DYNO Day Figures :D

[Age_S2000]

gday all

SASS Automotive down here in hoppers crossing had a Dyno day open to all cars were i went and enterd my S2000.

i won myself a little trophie for taking out Top 4cyl N/A

126.5rwkw@156kph/8300rpm in 4th gear on 98 BP Ultimate.

i know dynos are different so i didnt know what to expect but atleast i came home with something lol

the car has no modifications other than a K&N in the box.

i would love to supercharge it but abit strapped for cash so im going to do a single 65mm stainless mandrel cat. back system with a resi and a twin loop at the back i know gains arent much in these cars but that combined with a CIA will see gains of atleast 10 - 15rwkw lol i HOPE lol
if not the car goes hard stock and i need a clutch as it slips when changing.

let me know what your thorts are :)

Careful what exhaust / mani / CAI you buy. many on the market have proven to lose power over OEM.

Best of luck getting an additional 15rwkw out of the car. :thumbsup:

[dudeoflife]

guess there are so many variables when it comes to dynos ... i dynoed my stock AP2 and got 139kw/atw...

have fun with the mods .. wanting to dyno mine with my exhaust before i add anything else.

[ludecrs]

I get dyno'd on Tuesday for 12 pound.

w00t.

congrates on the trophy,
i should have stuck around and took out forced 4cyl class, ohh well, next time..........

[Age_S2000]

what CIA should i be looking at there are too many to chose from??? and i dont plan on spending anything over 600 for one.

[JAP-S2K]

Mine came with an Injen intake, when dyno'd with standard setup, the Injen made no real hp gain up high, and only made a slight amount of power in the midrange. Much the same for J's Racing, Gruppe M & Password JDM intakes. None of them give you a subtantial power increase for the $$$$. 2-5hp gain on back to back dyno runs.

lmao ill shut up now hahaha damn.........

so wat about exhaust systems i hear the most u can make is about 5hp with a single cat wack if done right.....

enyways what Dyno figures are other S2Ks out there pulling and with what mods....

im really not expecting many to answer that as there so hard to improve on unless big $$$ are spent...


ALSO

today i went to auto barn an bought me some spark plugs http://www.bosch.com.au/content/language1/html/5684.htm
Bosch Platinum Fusion

here are two different K&N intakes ones short ones long(typhoon)
http://www.knfilters.com/search/product.aspx?Prod=57-3514 SHORT
http://www.knfilters.com/search/product.aspx?Prod=69-1040TWR LONG
the short one makes 9.5hp@6500rpm and the typhoon makes 6.7hp@5500

I had the short one - the K&N FIPK.

Sounds the best IMO.

Costly to import from the US however, even more so with todays current economic USD / AUD conversions.

ludecrs is it true if the resinator + some of the piping is removed on an s2000 it gains alot more hp? because i've been told by many because of the emission laws they had pipes and whatnot put into the whole system to reduce power + emissions + sound?

[vyets]

same with every car mate..

Every car has a Catalytic Converter to reduce toxic emissions, and a resonator and mufflers to reduce noise.

[9large]

I made 14rwkw on a DynoDynamics with CAI and exhaust. I had BP Ultimate in the car.

[vyets]

Good gains :D
were they done on the same day?
What cai and exhaust?

[F20C]

vyets i understand every car has it, but is there power gains if those are removed?

[vyets]

yea as long as when u replace it the pipes are straight or mandrel bent also the same diameter and good weilds

[Age_S2000]

i was told u need to have the center resi on these cars other wise u loose.... im confused??????????

[vyets]

Yea some cars will loose power once you remove certain things. in theory it would make more power. but only way to find out is dyno it remove it and dyno straight after to find out. It won't be a massive gain or anything 1 - 2 rwkw if anything.
If you want power get a 70mm Header back without resonators.

[F20C]

what would the invidia n1s do? or the j's racing?

[vyets]

lol can't compare the 2.
1 is ebay crap
other is a high end jdm titanium.

the J's will be better caus its a titanium and will save you about 20kg's over the stock unit but cost ur wallet alot more

[F20C]

lol gay i thought the invidia would add abit.

[dc5ive]

i fitted my hks cat back havnt fitted the headers yet... dont really feel a gain
its still the same as it was before just sounds sexy =]

[vyets]

invidia will, if you get the single, and louder too!
Singles always ad more.

I'm not talking about the J's Dual btw haha

[ludecrs]

lol gay i thought the invidia would add abit.

The combination of my Invidia exhaust & Toda headers saw a 5-12rwHP gain across the rev range.

[Age_S2000]

yea but thats because ur car isnt stock try that on a stock S2K n it prob wont???????

[JAP-S2K]

Exhausts are one of the hardest things to gain power in right across the rev range in an. Either you lose alittle in the midrange and gain some up top. And it's very easy to make less power than oem. Most Jap systems work well but do require engine mods to perform at there best. That's why most are offered in 65mm and 70mm diameters.

[ludecrs]

yea but thats because ur car isnt stock try that on a stock S2K n it prob wont???????

That was when I was stock.:p

[Age_S2000]

omg omg so u can get gains from headers too its just about getting the right combo n setting it up properly....


hmmm keepem comin im sure im not the only one this is helping

thanks to every one for there thorts and inputs......

[vyets]

Gains upto 20rwhp have been seen with a 70mm single straight through alone.
But lets not talk about hp it's australia :P

I dyno'd my car along time ago when it was stock.
I got 136rwkw i dont remember at what rpm but :P It was like 9000 or 8800 something like that.

[Age_S2000]

hmmmm 70mm thats 2 3/4" yea? i like wat im hearing but i dont want loud either lol

[vyets]

2.75"
Trying to find a place that can make me a custom 70mm muffler and resonator :( no such luck

[ludecrs]

But lets not talk about hp it's australia :P


****!, all my numbers are in american so I know what to compare it with!

i say HP all the time, and every farker goes, 'whats that in kilowatts?' and I have to sit there and figure it out approximately. Shits me! :p

[Age_S2000]

lol google.com search online conversion lol then ull know im good with Hp so what ever u know is good to me :)

[F20C]

i see i might look into getting toda headers then with the invidia n1's.. considering invidia have a header set, wouldnt that add good power? with the n1's that is. btw what exactly would cel fix in a test pipe do?

[ludecrs]

Stop you from getting a cel code.

[vyets]

oh and cel is .. Check Engine Light

what mods do you have done to your car vyets? what exhaust the most gains would be from the exhaust and the js racing intake hey?

[vyets]

I don't think there would be much gains with my J's intake, since the scoop sits down the bottom most dyno fans point into the enginebay where the SRI type intakes should perform better.

I don't have any power mods lol. Only a bazillion bars.
I have the J's intake and a Greddu EMU. Also I chopped off both the stock mufflers for weight, and sound. Pretty sure I'm losing power but LOL, because I got a real crap job done to extend the pipes and crush bend em so they exit straight haha. It's real ghetto but I'll be getting new exhaust soon. It sounds off its **** but and real loud, but no drone woo!

here's a dyno that me and erik (3R1K) did back in february...

I'm taking one has had a ratio change. 4.777 my guess.

[9large]

Good gains :D
were they done on the same day?
What cai and exhaust?

Injen CAI + T1R 70

Biggest improvement was actually weight loss. Yes, dyno was done on same day. An AEM V2 (an almost identical design) will give you similar results power-wise, but it sounds different to the Injen (it's more metalic sounding). The AEM V2 also produced a smoother power curve, and has a little drain hole at the first bend (near the filter) to let out excess sitting water.

Do some research on s2ki - you'll get a lot of good info there.

[9large]

Most Jap systems work well but do require engine mods to perform at there best. That's why most are offered in 65mm and 70mm diameters.

Not sure what you meant by this - what did you mean? So are you saying exhausts need to be 65 or 70mm in order to work well, with or without engine mods? What are the sizes of non-Japanese exhausts? The sizes of good exhausts that generate power are related to their respective abilities to optimise exhaust scavenging, based on desired engine characteristics. Some brands just copy. N/A and F/I usually have different requirements.

[h17am]

h17am wat mods are done????? and wat were the gains????


Mine = 179hp
3R1K = 165hp

What I have that erik doesn't:
intake, larger tb, thinner head gasket, test pipe, ecu

What Erik has that I don't:
70mm catback (mine is only 60mm :()

and yes my car has a 4.4 final drive vs 4.1 on erik's. Doesn't make a difference on power though.

[Age_S2000]

:O :O :O at 120kph u have 25hp more :P what quarter mile times u pullin mate i like it :)

i might goto s2ki and do some further reaserch on CAI and cat back exhausts....

so far the 70mm cat back is the way to go but like i said i dont want all noise i want go and id prefer it to be quieter too. as for the CAI the Short K&N still tickles my fancy so ill run with that i think but like i said ill do more reaserch....

any one got pics of there CAI or exhaust


h17am - were did you get the Throttle body and how much approx?

N/A and F/I usually have different requirements.

What i meant was that most Japanese tuners offer an exhaust which will improve engine response, sound, and still remain legal(not always) and are a bolt on fit and are designed for a standard F20C. These are generally 60 to 65mm. 70mm systems are generally designed for track only use as nearly none are quiet enough to comply with any epa laws, and most do not have a cat option.
Obviously a 70mm system without a cat will flow better than a 60-65mm system with a cat. And it will produce more top end power, but you lose some throughout midrange power. IMO 70mm is useless unless your constantly up it. Sure, exhaust flow generally equals power, but back pressure also plays a part in N/A tuning. I'm not saying the 70mm are shit. I think there not intended for street use.

[tekung89]

tune the car to however its gona be used or dont touch it at all. a car built for everything is pointless

Well, you've got a few generalisations there, and you've contradicted your previous post - there aren't too many exhausts with 65mm tubing :) You are correct (in your latest post), that most systems have 60mm piping, but probably not as prevalent as you'd think. Doing some quick research of 86 exhaust systems for the S2000 - of the exhausts with reported sizes - 37 are 60mm, and 23 are 70mm. There are 3 of 63mm size.

Sure, 70mm exhausts tend to be louder than the smaller ones, but this doesn't mean that they were designed for the track, and vice versa. A lot of the manufacturers make exhausts in both 60mm and 70mm tubing intended for either or both street and track use. Note, that these Japanese manufacturers tend to design these exhausts for their largest markets - Japan and North America - where respective local laws usually differ significantly from those in Australia, and may be less strict. A common theme for N/A cars, however, is that single exhausts tend to dyno/produce more power, making them more attractive for race tracks where noise restrictions aren't in place. Sure, we all know that a lot of mods make no or less power to the F20C, but FWIW, after having the intake and exhaust installed a few years ago, I dyno'ed significant gains in power and torque over stock, across the entire rev range - there was no loss in mid-range and big gains past 6K.

But seriously, if you want to make the most power-per-buck, you need to go F/I.

does enyone have a spare LH Head Light washer or know were i can get one other then honda.... i had a tiny accident last night and broke that only.....

PM me please :(

[vyets]

There are alot of 70mm catbacks with resonators avilable.
Greddy TI-C, J's Racing 70RS, ASM S-Special 70, T1R EM 70.
Both the ASM and the T1R are very very quiet 70mm systems.
Then you got the full blown race ones like the
J's 70RR, Amuse R1000, T1R 70RT which are the full header back systems with no cat and resonator.
And most 70mm exhaust will gain through the whole rev range.

There are alot of company's coming out with the 70mm type exhaust now, obvious reasons why they just gain more power.

But most people are not after power but are after sounds and looks thats why Duals are available and 60mm Duals for the super quiet and looks.

Yeap back pressure does play a part in NA tuning, but that was back in the 1.6L days with our 2.0L a 70mm is fine. Not just for our F20C, but most of the K20 guys love the 70mm they gain heaps.

Yeah, perhaps i didn't make myself clear on exactly which systems i was talking about. And perhaps what i should have said is single only systems. As there are only a few (IMO) that are worthy of getting, sure there's heaps out there. But again IMO I don't bother to mention any of the crap copies coming out of the states or elsewhere. As most performance worthy parts do
come from Japan as most tuners do R&D and a small amount from the States. I personally seen a full J's 70 titanium seen run back to back, factory vs J's, and seriously the gains were far from being impressive to brag about especially for the price.
As for dyno figures, It's difficult to quote as there are always more than 1 aspect that will change figures.
You mentioned a significant gain. What is a significant gain? I might think 5-10hp is lame. Yet you may think it the bee's knee's.
Yeah i agree, you want a significant gain, forced induction is the logical answer, yet so many people are quick to think you get massive gains from installing a CAI and exhaust. Lets be honest, the gains you get from doing cams, head work, quad throttles and possible storker kit, are still nothing to brag about, especially for the money you need to fork out.

Sorry but if everyone modded their car according to back for buck everyone would be stock.

Most mods out there cost a shitload and hardly supply any performance. Even a full blown turbo setup, with all the custom shit you'll be going through and tuning back and forth it's not really bang for buck either.

and a 5-10hp gain over a 2.5" system which gains another 5 - 10hp over a stock system = a 10 - 20hp gain 10 - 20hp is still pretty lame, but thats the NA world, not like your going to be making that power anywhere else.

And back for buck?

Greddy TI-C single $500 USD, 70mm Cat back single exhaust with resonator and made by a Good brand. I'd say bag for buck if it wasn't for the exchange rate + Shipping.

And the Greddy TI-C 70MM single is designed and made by Greddy USA

Yea agree on getting a cai, or a header or a exhaust wont give you gains. But put all 3 together and it will. Tune em up and it will give you an even better gain, worth the money or not? It's really upto you to decide, thats why you have people who do ebay brands and some do high end jdm stuff.

One part will not give alot of gains, the gain will be more substantial if you combine multiple aftermarket parts.

I agree with everything you've said, and the shit exchange rate doesn't help the fact that every trick part is worth a bomb. True adding all three can give a power increase, lets be honest though, not always. True N/A tuning is a royal pain with a S2K.

[Age_S2000]

what about NOS????

has enyone ever set up NOS on the cars ANY Honda not just S2K?

[vyets]

Heaps of people have a nitrous setup in basically stock cars in the states. Here not so common, but I did go to a drag day about a year ago with some mates and he brought a mate with a b18 ls with some nawsss. it didn't go as well as we thought it would.. Slower then his time without the nos haha.

[Age_S2000]

id only run 50 - 60hp shot but.
in the laws of nitrous its safe to use on a stock motor upto 25% of its HP at the flywheel.

S2000 - 25% of 240hp = approx 55 - 65hp

hears one with 100hp shot ;)
