9:1 vs 10:1 aint gonna be much difference my bud, maybe a few ft/lbs in tq. but the s2k before that i did, had a 35R on it and on the 1 BAR map sensor(stock) we made 379@12psi on AEM<U>(Mainstream performance got 362@13psi before i tuned it)</U>

I just really think something is up. Im not trying to go starting a pissing contest with anyone but it does seem a bit high. i mean look at the full-race car you talked about.

anyways, good luck with the car they are very fun to drive with HP

so far on our s2k KILL LIST we have, 3 trannys and 2 rear ends. all the s2ks either have the inline pro z32 conversions in em, and rebuilt trannys, i snapped a tailshaft section almost completely off in a 3rd to 4th powershift </TD></TR></TABLE>i understand how you feel since i couldnt believe it either...dynos to me are just used for tuning and to show if a change in your setup has increased your power..on this car baseline was 177 and end result was 499.5 so we nearly tripled the baselines power...that is why the owner is happy...anyways the owner will be trying the car on some different dynos just to see how they stack up

 

It was great to have another S2k at the shop. I own the yellow S2k and was very estactic about his numbers. Unfortunetly it also confirmed the worse on my end. #1 is oily and fowled and #2 is not in the best of shape. A loose map created some lean conditions that have for sure added to its undoing. On the great side was this car coming in and setting an example to confirm why worst fears.

No joke this car is making the power. Not only do you have a turbo that is more efficient at this psi and range of use at 10:1 compression but you have a great engine builder to back it up. There is no telling what power this car is going to make later in its life. Congrats and glad to see another S2ki in the area sporting its stuff.

Yeah i told brain about your plugs, and the IM flaw the s2000 has for a FI application. i think you should have him put the the 3 bar in and do a little work to the map. Hope to see your car make some higher #s. See ya around.

these are the last 2 i did, both of them in the same shot

Yes dynos are a tuning "tool" but to me i would not want a customer to go out in a "500" hp car and get destroyed by a "300"hp car, or have it reflect in the trap speed MPH. All it does for a tuner is reduce his tuning credentials, and in return give people a reason to say "aww man that dyno is screwed up" or "that guy doesnt know what hes doin"

Having a an MD dyno i know how much we have to always stay on top of calibration of our dyno and i show every customer the calibration numbers are3 correct before we start makin pulls, jsut so they know without a shadow of a doubt that it is correct





here is what the white one made

</TD></TR></TABLE>those are very nice cars..you should make your own thread instead of whoring on mine...i am not the tuner nor am i the dyno operator so if his car gets owned by a 300whp car it is no reflection upon me,i merely built the engine and selected the parts...the owner has a tentative appt at the local mustang dyno next sunday so we will see then how it does on a dyno like yours

sorry I'm not up on my Hondas yet

regardless just seems like an abnormal drivetrain loss

oh well, car sounds like its a beast now

on a car that stock with 240 crank hp, to put down 177whp is close to a 25% drivetrain loss. i think normal is around 20% on rwd manual trans, so it's not too far off just depends on the type of dyno. nice build

 

clutch?

roger that, will do

 

Nice!! Must be a blast to drive!!

 

Very nice car. It has been in my neighborhood the past couple of days. This car sounds sweet! I will have to come take a closer look next time you are in the area and I am not in motorcycle gear.

ahh that is to funny

 

That's quite a bit of power for roughly ?14lbs? on a DD. I would have expected 450whp - 470whp on a DJ at roughly 15lbs. None the less. Get some video of the car. Looks very nice

 

i thought it was high myself, but im sure it will be confirmed in a couple of day when he hits the next set of rollers


Car and engine looks fantastic, makes me want credit cards.lol

Have fun kickin that thing side to side mang

 

That would have to be one of the most efficient engines to make 499.5whp at that boost level. if you take into account the 63hp to turn the drivetrain, that would be about 562.5hp at the flywheel. According to the 3076r compressor map, at a PR of 1.88 it will make ~46-47lbs/min at most before choking, an thats in a rather low efficiency area. Even at 11.8afr the engine must only be using about 0.42lbs/hr of fuel per hp. (47/(562*11.8))*60. That is almost as efficient as an F1 race engine. I would definitely check the results on other dynos. I'm not saying it's impossible but unlikely that the motor is either getting enough air or using the air it is getting efficiently enough to make that much power.

 

dyno plans are on hold...fuel pump failed and the engine is hurt bad....we are gonna open her up this week and check the damage

 

Holy ****. Dudes. Man I feel for you. Man my hopes for a quick fix and return to the field. The four of us should get together and share hurt motor stories. Always seems to make me feel better. "300" in Hd anyone?

-Xcat</TD></TR></TABLE>yea it sux..its not even my car so i know im not the saddest guy in town right now...we will get her going again..i doubt the rods are damaged but im sure the pistons are probably gone..the owner told me their was little chunks of grey stuck to the remains of the plugs

 

I agree. It isn't my car but i know the feeling after this week. Hoping for the best for both of us. Merry X-mas. That really doesn't sound so good anymore.
