My S2k Dyno run!
 

Ok so I just put my 2003 S2k on the dyno and had them run it up to 8700rpm. My first run was 187whp and 132 torque, 2nd run 190whp and 135 torque. I was running 12.45 AFR all the way along, they said I am rich and would be fine for boost but since I am not I can lean it out and make more powa.
I was bang on what I though it was going to be for torque and around the same area for HP.
All it's got is AEM intake, HKS exhaust, AC delete. Do these numbers seem to be pretty acurate??

My link

those numbers seem kinda low i think... i dynoed at 202 whp with exhaust, intake and header on a low reading dyno and 215 whp tuned. It all depends on the dyno though, some read higher then others. What dyno was it?

thats mine

Not sure what kinda dyno it was, I will ask tomorrow norning. But it was done in 4th gear and I was runing rich.

yeah man find out, mine was done in 4th gear and i was runing rich before the tune as well!

They use a dynojet...

I don't think you are running all that rich, max. power is usually around 12.7 a/f , you aren't that much more rich than that level, maybe just a tad. 190 whp seems decent, but every dyno is different, I always like running in 3rd gear myself, less load on the engine and the run goes quicker. In theory the gearing is not supposed to factor into the numbers but I always found 3rd gear produced better numbers, fwiw.

Unless you have multiple s2000's running on the same dyno, the same day, you really can't compare numbers.

what you should be looking for is have a base # and then tune and seeing the results

I am going to see what a street tune would run me.... As of now the wife don't know I had it dynoed at all Lol :zip: I figured 190whp was pretty decent since it's 227 at the crank so thats an 18hp loss over 8 yrs... I am not much of an engine guy at all! So this is all new to me but I wan't to learn how to get more power without boost! :LOL:

buy a different car or spend the same amount of money as a 400 whp turbo kit and buy ITB's a stroker kit and an aem ems LOL hopefully you will be making over 250 whp

actually you don't really know if the car has lost any power at all, it might have put down 190 whp on that same dyno when it was in brand new condition since all dyno's put out different numbers. Not knowing the starting point of that vehicle on that dyno is only going to confuse you, like Dom was explaining in his reply. Dynos are only good to record delta gains and losses of the same vehicle analyzed on the same dyno over time, they are tuning tools only. Having said that, I think it is safe to say that your car is probably running in pretty good condition, you aren't out of the expected range IMO.

Like Cleans2000 stated, NA hp is crazy expensive on this car, somewhere in the range of $100-$300 per hp, either go boost or stick with oem or minor bolt ons at the most, unless you have a lot of money to throw at it.

you guys should have a s2k dyno day again!

nick have you passed 300 yet?

to the OP: number seem ok. i love that sound of the HKS exhaust.

Hmmm Boost it is then! :argh:

s2k dyno day n/a winner will be S2KING... hands down il take bets on it right now lol

Colin the numbers seem reasonable for your car. I would expect anywhere from 185-205 on a stock motor with bolt-ons depending on the dyno.

Don't worry so much about the # itself, it's just a measurement- As you can see- your car is the same and it pulled 2 different #'s. Dyno should be used to get baseline- then tune. The overall #'s dont really mean near as much as people like to make it seem.

If you want power- N/A is very expensive and it won't net you noticeable gains without spending thousands and pulling the motor completely apart.
$ for $, boost is the best bet.

Its funny you ask cause I'm looking to do some tuning in a couple weeks.

siiick! let me know i would love to be there when you're putting it on the dyno.. seriously!

im getting pro-tuned this friday. im stoked!

when did you swap the wrx engine into your S?

Whats done to s2kings car? Isn't that the blue one with the j's wing?

um password jdm intake/ t1r header, t1r 70 mm (forgot what its called) is the straight piped one with the dolhpin tip, 4.77 gears (yes 4.77 gears on an ap2 lol), lightened flywheel clutch, aem standalone, im pretty sure hes going nitrous as well. When his build is done that thing is gona be retarded!

possibly a stroker kit.

Pretty sure there is a member from Ontario who was posting in the N/A forum about a Toda stroker kit and ITB's... :tipwink:

Not really sure what you mean..... :ponder:

Don't be concerned how much power you made in the end dyno's are like apples and oranges. Use it as a tuning tool that's it nothing else most people are dyno queens and just look for big numbers I wouldn't worry about it too much we don't drive DSM's, SRT-4's or Supra's. look for a consistent power-band on each pull and tune to your driving style i prefer a good few pulls and then take it on the street for a street tune it all depends on the tuner or yourself how much power is based on the dude who did the configuration in the morning. Car A could get 200whp on Monday when Joe did the calibration and Car A could get 190whp on the same car on Friday.. Car B on Saturday with less mods got 202whp when Bob did the calibration get it? . It's good to see what a stock car does and slap your bolt-ons on and dyno it again and see what you made on the same settings on the same dyno and possibly the same day, weather conditions etc. I wouldn't worry too much about numbers.

which shop was this? The last few years the southern Ontario guys have dynoed at Tag racecraft in Oakville. Does anyone know if a dyno has to be calibrated?

to the op, what was the temp and why did you only rev to 8700?

I had it done at DaSilva racing in Pickering, they mostly do mustangs and corvettes but the owners son seems to know a bit about Hondas and it's only 5 min from my work, I have been there with prev cars. $80 for 2 pulls.
I only had them rev it to 8700 becuase it looses power after that. My perfect shift point would actually be 8500 rpm, thats when we saw it start to loose power.
Temp outside was maybe 10c... It was rainging and kinda cold! It was on Tuesday.

That pretty much sounds like many other set ups in the southern ontario area...
Would be interesting to see the numbers on a dyno day though!

If you were shifting through gears, you would want to rev to the limiter so next gear would still be in VTEC so your perfect shift point would not be 8500.

AP1s loose power after 8300rpm due to running rich. Lean it out a bit and the power holds near peak. When my car was NA base dyno was 200whp with HFC comptech intake and fujutsubo exhaust. Tuned was 210whp with 201whp at 9k instead of the initial 176whp.

what were u tuned on? that was so similar to my dyno 202 and after tune 215

With an AP1 what are my tuning options? I understand K-Pro isn't going to work, so is it AEM EMS or cheap out and get a VAFC (but way less options\potential).

Mine was tuned with a vafc at the time.

Hey guys, I have had my 2006 S2000 for 2 years. I have decided to install the SOS stage 2 kit. I live near London Ontario and am looking for a tuner and dyno. Any recommendations?
