Your B16A dyno results?

[bizee_1]

Thanks man :thumbsup: What I/H/E do you have? (if you don't mind me asking), and do you remember what you made few years back at the Mr Druitt Dyno? I did 74.5kw on that day with a stock motor (just wanna get an idea of what gains my bolt on mods did)

Cheers!

By the way, back then, i thought maybe ecu was chipped. So Tinkerbell wrote down it was. Found out later it wasn't.

i/h/e = K&N pod, not so great OBX SS 4-2-1, 2.5" cat, thru to 2.5" cat back done by Hitech Mfflrs. Tuned Hondata. So you can see why i'm lil concerned in other thread lol.

i was thinking, got tuned with mobil 98. But since everyone had shortage of 98pulp. only one i find is Starmart Caltex to have 98pulp. Also got a dent in my header. but those wouldn't be much gains.

when it got tuned, it pulled 105kW. It got tuned on same Mt Druitt dyno, but diff day. So how that compares to our results on sunday, i'd say quite well for the mods you did. :)

If you need it tuned in QLD, go see HiPower :D

[fatboyz39]

wow... nice numbers from a B16a...

Going down the 1/4mile?

[kraiye]

thanks.
just let me get used to the bloody clutch 1st!!
lol
my feet have grown heavy and imprecise from driving a stock D all the time... traction is now an issue ;)

i'd like to say i put a lot of effort into it but i cant claim any praise cause i bought it with the work done... just not tuned

[teh_mechanic]

kraiye,very nice number from a b16.
makes me want to put CTR pistons in mine to up the compression a bit
really couldnt be bothered though haha

if tractions getting to be a problem at that power (its big power for a b16 but not really that huge a power figure in reality) then you really need to look at getting some better tyres,spoil yourself and get some good rubber,the difference is amazing.

next mod i would suggest is final drive replacement,or get a CTR gearbox,comes with short ratio gears and lsd....mmm nice

[kraiye]

thanks mate, i am very happy with it. and when they told me the potential is there for more i was... even happier :p
the tyres i had were pretty old and bald (so alot of fun!), it's got some cheapies on it now for rego. after the tune and fixing odds and ends on my other car i'm pretty darn broke (plus i need to spend a lil $$ on the missus for a while ;))
lsd would be sweet and i'm happy with the ratio as is - in the end it is my daily. much closer ratio than my cxi anyway!!!

compression came out to 12:1 too
:thumbsup:

[Waggy]

I'm very, very glad it turned out well for you man.

Ah, the good things about living in a capital city.... you (and HPR) went and did what two supposed "king" tuners couldn't.

That power figure is even more than what I thought it would make (I got told 120kw) and there is more in it once you let the HPR boys loose on the cams! :)

And yeah man, it's yours now. You should take the credit for it because it's YOUR car and you got it tuned properly. Now, all you need to do is give me a ride in your EM1 and show me. :thumbsup:

[kraiye]

lol
ok it's mine. just doesnt feel like it yet... still excited i guess :D
maybe we can swap rides when you come down

and sorry sydney boyz, IT'S MINE!!!!
mwuahahahaha

[JasonGilholme]

since when did us QLD boys steal cars from SYD?? lol

QLD Hondas ftw yO!!!

[kraiye]

i saved yet another QLD car being stolen from us ;)

ITR box you mean... CTR ratios are same as the 16A box.

:thumbsup::thumbsup::thumbsup::honda::wave:

[RtN]

BWAHAHAARR.. you got no tune-ability.. you have NO variables with the standard ECU.. you cant tune shit without programmable Electronnic Management System... derrr

however IF you had VAFC or Greddy eManage.. up to Power FC, AEM, hondata, Motec etc, you have FULL tunability !!

VAFC is full tunability? I thought it just changes VTEC engaging point and throttle body positions... is it?

[kraiye]

maybe he meant V-AFC II, although still not all that tunable

buy my emanage ;p

[hui]

I've seen dyno operators fudge the "post mod" runs to make their customers happy. That's not saying it happened to you, but it does happen :?

yeh thats so true....

[innozent]

possible to have a look on dyno sheet?

:thumbsup:

Hi, just wondering how to get 12:1 CR on b16a with ek9 piston :)

[todaek9]

how do i convert 2xxpsi to xxx:1 compression?

[dsp26]

how do i convert 2xxpsi to xxx:1 compression?

you can't because he's talking about static compression

even if you have 13:1CR ur cylinder psi could only be 200psi coz of camshaft duration overlap... and altitude...

just use this as a guideline to guestimate:
B16A2
220psi = 10.4:1CR

B18C7 (i think)
240psi = 11:1CR

***EDIT***
there is a calculator out there... but you neeed to know every aspect of your engine from head gasket, camshaft, pistons etc...

Hi, just wondering how to get 12:1 CR on b16a with ek9 piston :)

Don't know if it would be 12:1, but it would be close. Kraiye's B16A has a rather worked head with lots of milling involved.

[kraiye]

12:1 may have been rounded up a little ;)
it's funny... i've had one person say 125kw is near impossible for a b16a and another say it's pretty average i should get more.
lol

[spoondc2]

Don't know if it would be 12:1, but it would be close. Kraiye's B16A has a rather worked head with lots of milling involved.

Always wanna know how to achieve 12:x CR with b16 stock block and head with ek9 piston. I will be lot more than happy if anyone can tell me. Since I think i can only do 11:3 CR max

Good figures on that dyno... you know what our motor made on that dyno, so its a good platform to compare..:)

[mrwillz]

that sounds awesome for a b16a2

at teh gtcc dyno day
got 92kwatw
5zigen headers, stock cat, custom b pipe and mugen loop

eveyrthing else stock

[andiiso]

do intakes of any form at all give any gain ? or is it barely even noticeable on dyno type of gain ? like sri, cais etc etc

(Gain 4.5whp at top end and a slightly smoother mid range).. My Air Fuel Ratio was pretty alright according to the tuner except for one part which is way off.. didnt really understood what was going on though..lol..)

Got 134whp or 99.6kw atw..Dyno dynamics

[GRU53M]

I got 94.2kw at the wheels with a full stock B16A2 on a dyno dynamics DYNO @ Autotech in Canberra.
This is a Dyno run before i get anything done to the engine, Starting this week with the exhaust getting done and maybe a pod filter.

[delsol9000rpms]

any reason y its run on e85? yous made more power like that?

nice power..

[Benson]

Why E85

1. Emission friendly, burns clear and will pass emission easy
2. $1 a litre
3. Gain 3-4kw everywhere
4. Good power gains
5. Works even better with higher comp engines
6. Able to lean it out a little

Downside
1. Not readily available, only 2 servo's i know has em
2. Burns 30% quicker

[Limbo]

e85 also runs cooler apparently, the new audi run this with their turbo setup and can make some good numbers

ok fair enough...

[delsol9000rpms]

how is it for the cleanlinees of the internals of the motor.. as in carbon buildup on piston tops, valves etc?

[Benson]

haven't taken this head off yet. When i do, ill let you know the results

[vinnY]

shame you look like you're making a huge bomb when you go to buy a few jerry cans of e85 benny :p

any ill results on the fuel lines or seals yet?

[Benson]

E85 smells nice :p

[Limbo]

E85 smells nice :p
helps keep you high? lol

[Benson]

helps keep you high? lol

Makes me drive better :p

[dsp26]

sooo... i have a general question for the B16a owners here

hypothetically speaking...

would you trade ~10wkw at 6500-9000rpm for ~5wkw everywhere else below and not knowing the torque figures?

[Benson]

Ill trade 10kw between 8000-9000rpm to 10kw greater between 5000-8000rpm

We have already done this, so we are learning from experience.

[dsp26]

^^thats actually a better scenario, i would too... need cam gears right.. not achievable by tune alone?

[vinnY]

mid range gain > top end gain i say

especially for a street car
who drives around 8000+ everywhere everyday?

[fatboyz39]

^^thats actually a better scenario, i would too... need cam gears right.. not achievable by tune alone?

what are cam gears gonna do with anything midrange?

[Limbo]

i think Ron's talking about moving the timing with the cam gears to get the power band in the mid range

[Benson]

Combo of parts to get the right midrange..

might need to upgrade displacement or go itb's

[dsp26]

Combo of parts to get the right midrange..

might need to upgrade displacement or go itb's

yaahhh.. the BC3+ cams aren't living up to their midrange prowess reputation despite the recommended +2 INT setting that was supposed to give it.. as can be seen in our BC3+ equipped graphs, sure the curve is smooth but the biggest gains are still in the upper 6500rpm+ range

***EDIT***
it's just weird to me and i wanna fix it with cam dial if i can.... revving the car to 9krpm then shifting lands me around 6krpm with x-over at 6200rpm and my peak torque occuring roughly between 7k-8500rpm (1500rpm powerband).....

i know what some of you are going to say and an FD+install is waaaay out of the budget already.

[Benson]

BC Spec 3 are great cams for a simple upgrade. Ill suggest upgrading the bottom end to see the real result. b20vtec is bang for buck since you have most of the mods for it already

[bizee_1]

Ill trade 10kw between 8000-9000rpm to 10kw greater between 5000-8000rpm

We have already done this, so we are learning from experience.


what he said :arrowu:

[koldfire]

great to see and interesting results using e85...

anybody any idea which pump in melb selling e85??

[ef-civic]

i just got my car on dyno. not tuned. just power run. stock computer, jdm b16a just shitty headers 2 1/2 inch exhaust whale penis intake ITR throttle body. in 3rd gear got 98 kw - 131 hp. some people are saying should be done in 4th. what mine do better ?

[DNYALL]

98kw sounds bout right for the mods. I had similar mods except with 5zigen headers and got 100kw with my old jdm b16a. on another dyno, same mods i got 95kw's.

[ef-civic]

yeah i been told that my car has stage 2 cam shafts. but im doubting that now. previous owner is load of shit.

[markoJEK1]

should be run in 4th gear because the gear ratio is almost 1:1 , which will give you the most accurate reading

[ZeForce]

should be run in 4th gear because the gear ratio is almost 1:1 , which will give you the most accurate reading

Actually I tested this whole gear thing at the last dyno day.... did back to back runs in 3rd and 4th and there was only a 2kw difference.

[markoJEK1]

Fair enough, there ya go, tuners prefer 4th I guess

[delsol9000rpms]

also third gear wnt show the correct torque figures they will be multiplied.. due to gear ratios.

[ZeForce]

Depends on the type of dyno

[jspec civic]

my civic with b16b stock with adj cam gears (dont know if they've been adj) but
tuned with jdm itr and emanage blue pulling only 131hp atw does this sound right?

car had stock vti exhaust on it.

[mr dc2 vtecdu]

itr dc2,124kw atw .cold air intake,mugen twin loop,apexi neo. thats it .

[SPEEDCORE]

Afternoon jack offs.... Your B16A dyno results?

[Mikecivic78]

Sorry to ressurect an old thread, but I've had quite a fun time reading this old thing.

Most of this thread goes fairly off topic, but if anyones keen to post their new or updated B16a 1/4 mile/dyno results, I'd be really interested to hear them.

:honda:Atmo 4TW

[dougie_504]

I made 99.4kw on what was labelled a 'low reading dyno' by the mechanic/tuner (he said it's probably closer to 110kw).

Just running JDM B16A in EF8 CRX, ghetto DIY CAI, RS-R headers, 5Zigen cat-back.


The previous owner told me that the engine is internally stock but now I'm not so sure.

My mate made 100.7kw with port work, Skunk 2 springs, retainers, valves, cam gears, Crower cam shaft, CAI, Fujitsubo headers and legalis cat-back (untuned).
My other mate made 84.9kw on his B18C7 with CAI and stock exhaust (Neptune ECU).

So I'll have to take a look inside my engine when I do timing belt/pump/head gasket over the next week or two :)

Thanks for the info. No ECU tune on your EF8 yet? A big factor is the state of the engine and how many Ks it's clocked up. How many on urs?

I think 110KW is a bit far fetched, I've done a bit of research and i've read of many fairly low mileage stock-as-a rock B16a2s pulling 77Kw atw, so 99Kw doesn't sound too far fetched.

[newpaddy3]

unless you all use the same style dyno you will get different readings, just keep this in mind when comparing your power and whatnot

[dougie_504]

We all used the same dyno within 30 minutes of each other.

My engine is a 1990 B16A and has done 98,500 original KMs. Serviced every 5k KMs. Very healthy I believe. The mechanic said that of the 25 or so B16A's he's had on the dyno he's never felt one as smooth and easily rev'd up as mine. I don't think 110kw is far fetched for an internally mod'd engine, but for a stock internal one yes it sure is a lot to expect.

I'll post of the dyno sheet soon and we'll see if maybe I have some internal mods that previous owner wasn't aware of.

And no not tuned, stock ECU (checked that out when I got home that day lol).

[Mikecivic78]

That's why this is a good thread. So we can compare different results on different dynos with different mods.

I would like to see some bone stock B16a/B18C/K20a2 Dyno slips. I'm sure u've still got them somewhere!
Could you try to include (approx) engine mileage for stock results? Maybe I shoud start a new thread on this, I hope I'm not highjackin'.

Unless you open it up and check, it's hard to be defintely sure about what's in there. Otherwise, get another Dyno done at another reputable place familiar w/ hondas and compare.

I recommend you get a Hondata s200, they are heaps cheap from the 'States atm. Guaranteed gains, considering your I/H/E + (?internals).

[dougie_504]

If the head is built I'm considering B20VTEC bro. Hondata to rock it for sure

[GSi_PSi]

wtf a b18C7 making only 84.9kw +CAI+ECU.. ...
anyways can ppl post up their actual dyno graphs> or at least give us their tq numbers....b16a how shown good kw but curious to know the torque numbers

As I stated it's on shit headers and exhaust, running like a real dog so that he could get engineering cert. Will pull much better when it's finished but he just got huge hail damage which he might tend to first.

Here's my dyno graph:

Has your mate got a tune yet? To get that result after having all that work done is terrible!

I already stated that it was not tuned in the very post of mine that you quoted. Also his compression is about 5% off optimal and he needs to demolish his rev-limiter. Further, like I said previously, the dyno is a 'low reading dyno' according to the mechanic and should probably be rated 10kw higher +/-.

[KLR-16A]

My b16a2 in my ek4 made 113kw. Mods: -Type r intake manifold and throttle body, injin intake, HKS 4-1 header( headers were completly squashed), 2 1/4 catback, no cat. Head: Double valve springs, titanium retainers, and toda spec C's and adjustable cam gears. S300 ecu
Car was a monster but unfortunently only lasted one week as rubber from engine mount went directly into the timing belt and put the car out of timing :(. So therefore i bent 9valves in total. Now however i have gon b20 :)

113kw is impressive.

Where did you have it dynoed? Have you got a copy of the dyno sheet? Wouldn't mind seeing the curve.

Did you have any other work done to the motor while installing the cams? (ie port, valve job, increase compression etc)

[MRK20CRX]

This is a video of my ef8, it's pretty much stock apart from a k&n pod filter and an apexi vafc2, i'm not really into that much power, rather handling, and good choice of suspension conponents and tyres, to me that's more important than showing someone else I have more powerful car that them

Bump.

Where do you guys recommend going to get a dyno run. I just got a em1 and I want to have a dyno run to see what it makes before I start buying parts. Atm it only got a Injen Cai.

Located in south west syd. And how much does it usually cost. Sorry for the noob questions.

[Mikecivic78]

back from the dead.... but no Dyno results, not happy jspec89, start a new thread k3nt

need your dyno graph bor

dang how many km on the engine? mine stock did 101kw at Toys garage.
refer to page 5 of my build thread.

Don't go to byp.

There's a whole thread about them.

I think he's already been there

[newpaddy3]

I meant don't go back

Yes I saw that thread after I got my s300 from there :s habit worried now

Hi. Another OzHonda noob here. Thought this would be a good place to write about my B16A numbers when I had a working EG6 rally car along with some dyno sheets.
Just ignore my writing on the graphs. All runs were done over the years with Ed at Autotech here in Canberra on their Dyno Dynamics dyno. They upgraded to a different 4WD Dyno Dynamics around 2010 I think. My apologises for the fact that the graphs aren't in shoot out mode. Lastly, all runs were done on the same set of rally tyres. Not the best thing for gripping on a dyno and probably why the numbers read a lot lower than I expected. We ran a friends B16B rally car on the same dyno on the same dyno, changing from rally to worn road tyres and it went from 91kw to 105kw atw! Another guy with a different rally car has seen rally to road tyres knocking 1kw off the peak power though.

Anyway:
I hope these numbers all help some people who are looking at mods.

Setup 1:
I started off with it in standard OEM spec, just with Jasma extractors that it came with and dirty exhaust. Exhaust was some 2" piece of junk that had squashed down to 1" in one spot. It didn't make a difference. ~95kw

...then we removed the air filter for a 'best case' scenario:

Another nice 4kw atw from having no air filter was suprising. We tried advancing the dizzy at the time but it made no difference. Honda certainly built these engines well.

Setup 2:
I brought some OBX quads from the US, put air filter socks on them. Also replaced the exhaust with a nice 2.5" all the way through with a single hot dog and 2.5" straight thru muffler and tip. Went the 'Crome' route on the ECU myself just aiming for 13:1 on the A:FR at WOT. I also changed the gearbox to a Team MFactory one, with 4.875:1 Final Drive, and short ratio 3,4,5th at this point. Max speed was 175kph at 8,300 I think. 5,000rpm at 100kph down the high way was kind of noisy.
End result: 105-106kw atw:

Here's the same picture with the AFRs on it. And, from the time, my own estimation of the original 95kw run. Basically, it felt like the quads moved the power curve to come in about 800 rpm earlier. So much nicer to drive basically.

After a season of rallying and wearing the engine out a bit, it was down to 103kw atw.
I organised a dyno day and had the chance to run my car with a 2" straight through muffler versus a 2.5" muffler. Difference: 2kw atw...if you're interested.

Setup 3:
Time to get serious to try and give the turbo 4WDs a run for their money.
So, I used an EFI Hardware.com airbox to put around the quads, then had to extend it to keep the fuel injectors inside the box. 4" flexi pipe feeding it.
Mahle 11.5:1 C/R pistons.
Supertech valve springs.
4:1 eBay replica extractors based on the PLM B series extractors. Awesome looking set.
Davies Craig Electric Water Pump with mechanical water pump removal plate.
Red lines are the old readings from the worn Quads from Setup 2.
End result: 114kw

Here's the torque curve. About 15% more torque higher up.

Setup 4:
Unfortunately in doing Setup 3, I managed to cook the engine mainly because the radiator fan didn't come on initially. Big fail. As part of the diagnostic process, I removed the electric water pump and put the mechanical back in....
Blue line is the mechanical, Red is the Electric Water Pump.
End result: 110kw:

The graph above doesn't strike me as quite right as the blue curve shouldn't be to the left of the red (superior) curve. Fuel, tyre pressure, who knows. We hadn't changed the ignition curve between the two setups.

I hope this helps...

Thanks.

No offence mawkman but that tune still needs some work to smooth out the AFR's and a big thumbs up for all the rest of your developments.

[mawkman]

Yeah, Allmtr996, you are right - the AFRs aren't the prettiest down low in particular. :) It was really cost of the dyno time, and I only probably needed to add in a few more rpm mapping points in Crome, and in competition anything less than 5,200rpm is generally time to knock it down a gear. I wished I had the time to get it nice and smooth and get a few more kws out of the mid range consequently.

Thanks.
