Dyno Time with a B18

[Civic Type R]

OK i finally got around to a dyno machine to test out this new puppy of mine.
I went to Hyperdrive Dyno Dynamics as part of a shootout test to see how its all running.

Dyno result. 149.5HP@wheels = 111kw
Engine B18
Mods: u know them.
This calculates to be 211HP@engine using a conversion dyno run.

My previous run there was 124.7HP@wheels.
Engine B16A2
Mods: Intake, 4-1 racing extractor, full cat back exhaust, mugen twinloop, JDM ITR running gear

Red line is with the B18.
Pink Line is of B16A2

nice one!

[kenshin]

chase that 280HP !!

[spoondc2]

That's quite alot of gain....... Cool....... :)

[SiR JDM]

Top stuff thats some nice power... i wanna see some track times!

[DLO01]

Thats awsome man, well done. :thumbsup:

[Weq]

sounds good. look forward to the graph to see how the curve looks.

[Civic Type R]

oops .. i just rememberd i forgot to change the run in oil :oops:
fuk !

[DLO01]

oops .. i just rememberd i forgot to change the run in oil :oops:
fuk !
Doh! :p

[Civic Type R]

dyno chart added ..

[edw-R]

wow......nice job!!

[Perry]

woooow nice gain, wats the stock kilowatts from the stock?

[tinkerbell]

ha! i was spot on with my prediction eh? well, out by 0.5hp...

good looking A/F line :)

well done!

[Weq]

curve looks nice. fun car :)

[Civic Type R]

woooow nice gain, wats the stock kilowatts from the stock?158kw compared to 147kw

Im worried about that big dip with the VTEC changeover tho. :(

[tinkerbell]

do a search on VTEC dyno graphs, your worries will dissappear...

[Civic Type R]

do a search on VTEC dyno graphs, your worries will dissappear...i know its normal but look at it compared to the B16A2 line ...

[tinkerbell]

the B16A A/F line is abnormal.

for whatever reason.

[Civic Type R]

lol !

well the 4-1 header and catback made that line a LOT straighter..

[h22a accord]

thats a good reading! your civic must be a rocket. How much does it weight?

very interesting that my jdm h22a with mods consisting of pod and catback put out 111wkw aswell.

Adam.. I dont know how you got 211HP as my calculations equal 186.9HP at the Flywheel, but we all know that a dyno is only good as a tool for measuring gain/loss rather than an outright power figure. I thought your B16A got (typeR beating) 150something at the Dyno-comp ? now it's 124 ?? hahah WTF ?

Your 1/4 mile time the other week was indicative of a motor with about 200HP at the fly.. so the calibration of the dyno or whatever may have been pretty accurate.

what Management are you running there ? I also am not impressed with the bumpiness of your power curve. but this shows that with further tuning there's MORE power to be had :)

Why does the Torque reading drop off the scale when VTEC enguages ? is there a noticable bump/lag when you drive it ??

[tinkerbell]

Why does the Torque reading drop off the scale when VTEC enguages ? is there a noticable bump/lag when you drive it ??
because it is measuring Air/Fuel ratio?

[VTEChnique]

WHAT ?? isnt it the Torque (Nm) not A/F ratio ?

Ohh I see "AF:R"

would like to see the torque curve...

[tinkerbell]

Your 1/4 mile time the other week was indicative of a motor with about 200HP at the fly.. so the calibration of the dyno or whatever may have been pretty accurate.

very true,

i stated 2 days before the dyno run that:



from your 1/4 mile time i'd say you are putting out abt 150hp ATW on a Dyno Dynamics dyno...
http://www.ozhonda.com/forum/showthread.php?t=12583

[tinkerbell]

WHAT ?? isnt it the Torque (Nm) not A/F ratio ??
yeah, check the scale on the top right corner.

[tinkerbell]

oh - and thinking about it, the dip in the power curve shows that the VTEC engagement point is wrong.

i think it should be higher, like 5500 maybe?

(sorry to anyone wanting to buy your ECU)

[Civic Type R]

Adam.. I dont know how you got 211HP as my calculations equal 186.9HP at the Flywheel, but we all know that a dyno is only good as a tool for measuring gain/loss rather than an outright power figure. I thought your B16A got (typeR beating) 150something at the Dyno-comp ? now it's 124 ?? hahah WTF ? ??ok.
my B16a 160HP at the fly. Remember my I|H|E mod gave me an additional 10HP @wheels. = 180HP at the fly .countering drivetrain loss ... correct.. ?

so 180HP @ fly produced 124.7HP on this dyno. = 1.443
calculate this latest run of 149.5HP @ wheels back to the fly and you get 215HP

so its about 215HP ish.. but i was pedantic with the decimals last time. :D

Plus 215HP is what the engine builder told me it was rated at anyway

[Civic Type R]

oh - and thinking about it, the dip in the power curve shows that the VTEC engagement point is wrong.

i think it should be higher, like 5500 maybe?

(sorry to anyone wanting to buy your ECU)no it is 4800. you can hear it change over.
thats what i was saying before when i was worried about the line shape

[VTEChnique]

oh - and thinking about it, the dip in the power curve shows that the VTEC engagement point is wrong.

i think it should be higher, like 5500 maybe?

(sorry to anyone wanting to buy your ECU)

I am kinda agreeing here.. if u look at the curve at about 4500 you can see it is still climbing high and hasnt started to drop off.. in fact one could argue it's just getting 'on-cam' for the pre-VTEC lobes.

though a power sure when it hit's VTEC is ohh sooo much fun HAHAH

if it has ITR cams, the initial Lobes are optimised for the higher swithcover of the type R.. a B18C (VTiR) is mean to switch at 4800, but I think this is not the best for an R-related motor. My JDM B16A is at 5800 and is a little high I think as it has too much of a power 'spike' as the initial lobe is 'on-cam' at about 4500.

Ultimately you want a linear power curve thoughout the rev-range.

Adam - what ECU are you using now ??? does it have VTEC switch on/off ability ? Take us for a ride now it's a bit healthier than the last time HAHAHA

[tinkerbell]

yes, that's right, it really depends on how the engine 'breathes' on where VTEC x-over is optimum.

i had R cams in my B20VTEC and we set the x-over to 4200

and it is obvious your engine crosses over at 4800, i am saying that that is wrong.

i think the optimum for your engine would not be 4800 but maybe 5500?

the way to set VTEC is by enabling VTEC from say 3000rpm and doing a power run then setting the VTEC at 7000rpm and doing a power run.

then overlay both graphs and see where they intersect, this is the approximate point where VTEC *should* engage.

but you need a VTEC controller or programable EMS to do this...

[defect]

Thats some pleasing results :>

[Civic Type R]

Adam - what ECU are you using now ??? does it have VTEC switch on/off ability ? Take us for a ride now it's a bit healthier than the last time HAHAHAstill the Mugen ECU. and no it doesnt have the on off switch.

[VTEChnique]

so what did they do to make it run better ? just the injectors ??

what are you goin to replace the Mugen ECU with ? if you're running 14.2" with that ECU, you should just keep it.

[Civic Type R]

I installed a Walbro 450HP fuel pump. This provided much better air/fuel ratios and has prevented the engine from running lean in the upper powerband.
Refer to the dyno chart for the readings ..

The Mugen ECU is a great ECU but i think its better in someone elses hands rather than mine. I am looking at getting a Microtech LT8 ecu as its replacement. Id like an AEM EMS but cant afford it. I have to sell the Mugen one first before i get anything.

I should be running faster times but im not going to gloat about it. My launch techniques are crap for this engine.

[VTEChnique]

I hear ya.. I am only JUST getting my launches a bit better - is amazing the difference considering that you have the same chassis, suspension and tyres etc, yet the HP and torque characteristics of the new motors make so much difference..

[SINISTR]

:D I should post up our Dyno run then hehe from PAS... 147.8hp @ wheels with the wrong final gear ratio inputed for calibration, and only 7000rpm - the graph actually runs off the page as it still has pull... so I could expect over 150HP i recon?

and thats out of a VtiR!

Mike i did ask you to put the graph up last month, and besides, I pulled 152.6HP @wheels at Motorvation with a B16A.
Take your car to Hyperdrive and we can talk there.
;)

[SINISTR]

I'll post something up when the car is running properly, last night we broke down in the middle of the city cos thesame fuel line as about 4 months ago blew on us again - in the middle of peak hour traffic. :( so another FIXING job awaits me under the car over the weekend.

dude - that 152hp run 'in my honest opinion' was a freek run. There is NO way a 160hp engine + your IHE can have the car produce 152hp - your b16a would have had to make 200hp at the engine to make a realistic 150hp @ wheels... and you know and I know that wasn't the case!

in any case - each dyno is different. I was just stirrin. Our car made 147.8hp on the HUB dyno from Speedworks, which again in my opinion is the better type of dyno than a roller dyno - straight wheel power (no problems with tyre pressures blah blah).

one day hehe we can do a dyno day with your car and carolines car... same dyno - I recommend the speedworks hub dyno :)

[My-B18c]

go for 300HP then go munchin GTRS n GTS-T lol

FYI. i got 151HP @ wheels followed up with a 152.7 in the next run. It was on film and in front of lots of very surprised people, including many of whom gave me shit on Mirc for saying i am a dreamer for thinking my car got 140 on a previous dyno.
Go to Hyperdrive. Ive done all my dyno runs there. I have been to most other places in Perth. I want you to go to that one at Hyperdrive because its the most realistic dyno in Perth. Im not going anywhere else.

[SINISTR]

Im not reigniting anything - im just stating, regardless if it was in front of all the people there... its freeky how a B16A can make 152hp @ the wheels while your B18C made 149hp @ wheels. think about it... doesn't make sense...

[Civic Type R]

Mike stop posting meaningless crap by comparing a totally different dyno run to another 11 months later on different machine.

For the 3rd time. Go to Hyperdrive and run Cas' eg on their dyno if you want to start who should be getting what. Then we can have a discussion.

Then we can compare our results ;)

[pornstar]

stop talking the talk and get the car on the dyno sinistr, i wanna see the outcome

[tinkerbell]

For the 3rd time. Go to Hyperdrive and run Cas' eg on their dyno if you want to start who should be getting what. Then we can have a discussion.

or take it to the strip and tell me the 1/4 mile time and i will be able to predict the HP output to within 0.5hp ;) :cool:

[Civic Type R]

or take it to the strip and tell me the 1/4 mile time and i will be able to predict the HP output to within 0.5hp ;) :cool:well i can debate that theory.
You were spot on with the dyno run but i had a mixed bag of times from 14.2 to 14.8 with the same engine. Only the launches were different etc.. plus you have to counter in gearing etc and rubber.

[tinkerbell]

see, you think it is about the ET, i *know* it is about the MPH ;)

Pornstar: the Dyno graph will be posted up tomorrow - deal?
the car was on a dyno. at the recent PAS (perth auto salon) dyno comp. we ran into a couple of problems and it wasn't going to compete because we didn't know the final ratio on the gbox, in the end we convinced the operator to run the car with a ratio of 4.7 (meant to be 4.4), without a tacho and only revved up to 7000rpm. it made 147.8hp and the curve at the top of the graph doesn't drop because there was still more to come but because we didn't know the propper ratios we opted for the safer 7000rpm cutout.

Adam - these are not meaningless posts... you're the one who keeps on bringing up that 152hp dyno run over and over again.


and besides, I pulled 152.6HP @wheels at Motorvation with a B16A

You are telling me something I have the right to express my opinion about - correct? so I am expressing my opinion... Simple.

[Civic Type R]

No mike. You are comparing your run on a different dyno to mine. I brought in the B16A as an example of how far out other dyno machines can be. Let it go.

Tinkerbell.. my trapspeed had a varience of about 3-4km/h

[SINISTR]

No mike. You are comparing your run on a different dyno to mine. I brought in the B16A as an example of how far out other dyno machines can be. Let it go.


so whatz your point? we are comparing B18Cs arent we- you bring in a B16A. WHY?


It was on film and in front of lots of very surprised people, including many of whom gave me shit on Mirc for saying i am a dreamer for thinking my car got 140 on a previous dyno.

obviously you were never competitive about the power your car made... yeah - right!

OK OK - im letting it go... not gonna say anything more...
the graph will be up tomorrow...

[Civic Type R]

OK OK - im letting it go... not gonna say anything more...
the graph will be up tomorrow...u sure ? .. good ;)

[tinkerbell]

Tinkerbell.. my trapspeed had a varience of about 3-4km/h
and you obviously DIDNT post what your lowest trap was, but your highest?

[pornstar]

Tinker, theres some folly in MPH guessing power too in the case where theres alot of wheelspin, whether its due to power or whether its due to bad tyre choice etc..

[SINISTR]

and you obviously DIDNT post what your lowest trap was, but your highest?

so with my gen2 crx - i got 15.86 - 142km/h - what would my power output be if you dont mind calculating for me? :)

[Civic Type R]

same :)
ET: 14.281
mph: 96.35
kph: 155.06
60': 2.276

[tinkerbell]

Tinker, theres some folly in MPH guessing power too in the case where theres alot of wheelspin, whether its due to power or whether its due to bad tyre choice etc..that's why it helps with gut feelings, LOL!

--

sinister - maybe 110 or 120ish on Dyno Dynamics?

i'd say your 60ft time was about 2.4 or 2.5 as well...

[SINISTR]

this is at the wheels right? thats not too bad from a 124 hp motor - but doesnt sound Right??? no loss or very small?

[tinkerbell]

yes.

[SINISTR]

mmm... would it be right tho? my car only makes 124+ mods IHE... so maybe 134 hp at most... i guess 110 would be more correct then?

thats 15.8 was achieved without the extractors though, and also the suspension wasnt anywhere near the setup at the moment.

[tinkerbell]

mmm... would it be right tho?
i have no idea!

it is really only based on the calculations in my head, i am not using some sort of 'calculator' to work it out.

but from what you say, it could be about right...

[VTEChnique]

OKAY OKAY.. we'll organise a VTEChnique Dyno Day and Adam can come down also and afterwoods we can all measure our penises and see whos is biggest BWAHAHAHA

Tink.. mine is 15.02" at 147km I think.. what HP you think ? i'd say 135-140 at the treads :)

hahah this thread is very entertaining :)

[Civic Type R]

Organising a dyno day isnt easy Bede. Most of the time 95% wont turn up.
I will post it on my forums to generate interest as well.
Im thinking Ken's Hyperdrive Workshop with his Dyno Dynamometer would be the best place to go. They dynoed my B16A and B18c there and a few other Hondas have been there as well. They are also pretty much spot on with realistic figures too.

[tinkerbell]

Tink.. mine is 15.02" at 147km I think.. what HP you think ? i'd say 135-140 at the treads :)

i'd lean towards the lower side of 135hp, but you musta pulled a good 60ft time with that ET and km/h... :thumbsup:

[SINISTR]

just a quick Q: on a rollertype dyno like Hyperdrive - what would be the best choice for wheel size/tyre pressure? i mean you can have 15s or 17s on a car... its different for the street and its different on a dyno... does wheel size and tyre pressure make a diff?

I would think a hub dyno would be better being more accurate as there is no above problems... straight off the gearbox...

m

[tinkerbell]

http://www.ozhonda.com/forum/showthread.php?t=12665

[SINISTR]

thanks dude - very interesting!

In that case I suggest we all do the hub dyno shoot out... instead of a roller shootout???

[SINISTR]

ok here is the dyno Run for my gfs Civic.

93 Breeze with a B18C2 Conversion, intake, headers and a microtech ecu.

as you can see the run finishes just past 7300rpm as a precaution, as the car has no tacho, and we didnt know the exact GBox ratio.

so at 7371rpm it makes 147.81 at the wheels with still at least 1000rpm to go.

http://www.redpepperracing.com/gallery/albums/genone/ach.sized.jpg

[Civic Type R]

they should have given you another run.
They would have run it in 4th gear and gearbox ratio talk means nothing Mikey. - lol
I agree there is more power to be had after 7371, thats obvious.

[VTEChnique]

WOW that's a much nicer LINEAR power curve !! none of this bumpy shit HAHAH

I agree with Mike - a hub-style Dyno rather than rollers.. Much more accurate.

and we'll need a tape measure too ; P

[Civic Type R]

tape measure ?

[VTEChnique]

yeah so you guys can measure your penises !! LMFAO hahahaa

[tinkerbell]

you walked right into that one Civic Type R!

own3d!!!

[SINISTR]

they should have given you another run.

I agree there is more power to be had after 7371, thats obvious.

they did - if you look close enough there are two curves there... one in a dotted line (1st run) and solid line (2nd run)

Because we didn't know the exact gear ratio for the gearbox and the car has no tacho Ivan wasn't able to calibrate the redline correctly hence thats why it finishes at the 7000rpm mark. if we at least knew the correct gearbox ratio, he would have been able to dial that in, and set the redline at 8500 and run to 8500 without the risk of blowing the motor. Otherwise it was unsafe.

There's definatelly more in that car - i recon over 150hp.... but i need to get a tacho first!


PORNSTAR dude - theres the graph for ya!

BEDE - hahaha! nice one

[Civic Type R]

yeah so you guys can measure your penises !! LMFAO hahahaaso i can flop it right out onto your forehead :D

Otherwise it was unsafe.i believe thats total crap Mike.
everyone knows these engines revv up to 9000rpm. Gearbox calibration is a load of wank.

p.s. my dick is the biggest :wave:

[VTEChnique]

so i can flop it right out onto your forehead :D

URGHH Adam that's just ****in foul bro !! you dont even joke about THAT shit !! URGHH

As for Ratios ? well that meas a LOT when a dyno has to calibrate HP.. with Ratios, if you run in 3rd gear you actually are at what 0.8:1 or whatever while 4th gear in hondas is as close to 1:1 as you can get - thus the most accurate HP figure.

Plus the engine will rev-out 'slower' as in there will be more detail in the curve for tuning purposes.

Mike couldnt rev that motor higher on the dyno safely without a tacho as the Microtech has no rev-limit set I think.. thus it would just rev and rev and rev untill it blew.

IMO ALLY Honda Dyno's should be run in 4th gear.

[SINISTR]

i believe thats total crap Mike.
everyone knows these engines revv up to 9000rpm. Gearbox calibration is a load of wank.



wtf are u talking about? are u even reading what I wrote?

its not the gearbox calibration or what ever u calling it...
because the car doesn't have a TACHO - ivan was going to pull it off the dyno, otherwise he doesn't know how if the limit he sets on the rev meter is correct. Unless he inputs the correct gearbox ratio - which for a VtiR is 4.4 and not the 4.7 (which is a TypeR) we put in. Because the gearbox ratio which we gave him was a guess and he knew about it he decided to rev only to 7000.

So don't give me shit, everyone knows just as I know that the engine can rev to 9000, but with an incorrect ratio in the dyno computer and no tacho - 8500 could be in fact 9500 and Goodbye to the engine!

thats the result we got from 7000rpm. what else do you want me to tell u?

[Civic Type R]

lol .
well i had to get my one back at you hehe.
Again Ivan of all people would know what the gears ratios for a Honda would be. Its not like a B series transmision is that rare a performance shop hasnt seen one before.
3rd gear will give a higher reading, yes, but i am running the same transmission as Cas's eg and no one has dribbed on about calculating ratios etc..

[Marz]

I love the way you guys argue over pissy 150hp hatches.
When you're popping 300+hp, THEN start a slanging match.
I'm sure if other car lovers read this thread they'd lose it laughing.

[SINISTR]

lol .

So u're running a VtiR gearbox now? Since when? You swapped a TypeR box into onto your B16A2 and they mates it with the current B18C... so now suddenly you have a VtiR gbox?

I didn't expect Ivan to know the gearbox ratios, he doesn't work with Hondas everyday, as speedworks is more a Silvia, WRX and skyline workshop. and in any case, he didn't know and he wasn't going to risk it, he doens't have any proof that the gears haven't been changed in the gearbox... a tacho is the best indication for him, so he doesn't need to know the gear ratios.

Its not about getting back at me... what are you on about. You wanted proof that Carolines car made 147.8 - you got it. Im just making a comment about all the little things that still haven't been sorted with the car - so still not the final readout of the hp but an indication of where it stands right now!

Im even going to give you a CREDIT here...so appreciate it :) *im sick of having these conversations of whos car is better* this was a Hub dyno - you ran at a Roller dyno so im giving an allowance that you may have lost power because of the type of wheels you are running and the pressure of the tyres etc etc... those are the variables.

Fair enought?

[Civic Type R]

lol Mike !!!
no need to get all flustered. I was getting back at VTEChnique with some humour.
My car is not better than Cas's and im not trying to compete. Infact i wouldnt be surprised if her B18 produces more than mine but i will repeat myself and ask for it to be run at Hyperdrive. Now you can see why everyone hates dyno vs dyno discussions. People take them too seriously and start throwing bullshit factors into the equation.

p.s. i thought you said u had the Type R tranny ?

[VTEChnique]

For everyone's Sake..

Caroline's Breeze is running a B18C2 with ITR cams.. has the stock Integra VTiR gearbox (4.4 Final Drive).

Adam's VTiR is running a B18(C) type R (hybrid) with 99 spec Type R gearbox (4.7 Final Drive).

Ivan from Speedworks did NOT know the ratio of any stock hondas.. you'll find that like most performance shops in Perth, his business is mainly Nissans and Subaru's as that's where the $$ is.

[SINISTR]

lol Mike !!!

dude - im not getting Flustered... don't worry about me! I still have plenty of patience left... and please don't try and turn this around on me now.
You have said what u have said, and adding "My car is not better than Cas's and im not trying to compete" or "i wouldnt be surprised if her B18 produces more than mine" - is NOT what your're thinking deep down because when we do run it @ hyperdrive and it does get less than yours because it only is a VtiR and not this BUILT up to the max TypeR like yours - I can just see the 'i told you so' will never stop. Yes each dyno is different, YES - the graph is there because u asked for it - and i just stated the simple reasons why it wasn't a complete run - not bullshit factors - as you say - FACTS.

and no - the transmission and engine is all VtiR stock with i/h/e and ecu.

[Civic Type R]

bottom line.
Mike. buy Cas a Tacho for xmas :D

[SINISTR]

bottom line.
Mike. buy Cas a Tacho for xmas :D

hehe :D - that is the plan - she wants to call it 'IVAN' cos IVAN was nice enough to let us compete, even without the tacho and under the enormous pressure he was under at PAS. so yeah - i'll get it engraved for her with 'IVAN' as well hehehe

BTW: the TypeR cam thing is incorrect or unproven - we haven't taken the rocker cover off yet and from the power it makes so far its likely all stock.

who told you it has ITR cams ?

[VTEChnique]

dont get a gay Autometer tach or anything - just get an Sir cluster or even a GLi !! factory tach much more accurate unless you spend like $1k on a top-of the line tacho..

[Civic Type R]

i believe the ITR cluster will fit

[SINISTR]

i believe the ITR cluster will fit

It will not fit like a eg one, its completly different - it will have gaps all over the place.

I love the way you guys argue over pissy 150hp hatches.
When you're popping 300+hp, THEN start a slanging match.
I'm sure if other car lovers read this thread they'd lose it laughing.
we talk about 150hp cars cause we believe in the Honda ethos...ie: NA all the way. Not getting a great high comp engine then taking 3 steps backward by lowering compression and bolting an 'all i can do is boost..press accel' turbo and thinking yer a god :thumbdwn:.

Driving a well tuned, correctly constructed NA is a driving experience in itself....power on tap no lag and the most confused look on the face of boosted drivers or joe mustangs when u hit 7500+ :D .

every hp matters in NA...if u cant figure that go back to play skool. :cool:

I am kinda agreeing here.. if u look at the curve at about 4500 you can see it is still climbing high and hasnt started to drop off.. in fact one could argue it's just getting 'on-cam' for the pre-VTEC lobes.

though a power sure when it hit's VTEC is ohh sooo much fun HAHAH

if it has ITR cams, the initial Lobes are optimised for the higher swithcover of the type R.. a B18C (VTiR) is mean to switch at 4800, but I think this is not the best for an R-related motor. My JDM B16A is at 5800 and is a little high I think as it has too much of a power 'spike' as the initial lobe is 'on-cam' at about 4500.

Ultimately you want a linear power curve thoughout the rev-range.

Adam - what ECU are you using now ??? does it have VTEC switch on/off ability ? Take us for a ride now it's a bit healthier than the last time HAHAHA


It may sound silly, but did you consider the person who performed the dyno run may have backed off to cause the dip in power. Look at the air fuel ratio curve. I just wanted to put that out there.

[Civic Type R]

Yes he did back off the throttle after 8500rpm ish or around then as i said it has no rev limiter. Hence i think this may have been the reason why the room filled with smoke ?

[VTEChnique]

the room filled with smoke ???????? fark !!! that not good !!
