709whp from Modern Automotive Performance!

I just went back and looked at the runs. Pretty much every one of them over 635whp was spinning the tires between 7500 and 7800. DSMLink showed wheel speed and RPM up to 8500, but the dyno was cutting off every single one. I didn't even really notice. On our "low boost" 25 or so lb's pull that it didn't spin (first "full" pull) it looks like it made about 450ft lbs (had a spike that said it was at 540ish) and 577whp. Horsepower stayed identical between 6800 and 8200 (within 5hp).

Spinning was the name of the game on our dyno. we really need slicks.(for the dyno AND for the track) I think the car has 725-740whp in it at its current boost level. It sure as hell should be making that.

And that is why the car ran like poo under load up here.

Slicks should be coming!

I guarantee you were NOT spinning tires, now the clutch/power of the motor, thats another story..but there was NO rubber left on the dyno. I am afraid to come to your place without MASSIVE slicks to try to hook.

With the power spread out between 4 axles versus 2, you will not have traction issues up here for quite some time.



On a side note:

Was that E-85 car running 100%?
If so, its looking like there is an 18% power difference between the 2 places. Obviously this is a 2wd dsm to a awd dsm from dynojet to dyno dynamics. That is just number crunching the other car that was run here, as kyle's was obviously having a tuning/load/clutch? issue(s).

I'd like to run a few more fwd dsm to awd dsm tests to make a more concrete comparison estimate.

Back on topic:

That being said that car is SIIIICK. The sound, the setup, you guys should be rocking the track hard once you get it all figured out.

Sorry for not being clear, but I was talking about when he launched behind the shop, lol. I know he's definitely not spinning his tires on your dyno. Even assuming 700whp, thats only 350whp per axle, not enough to spin. Our dyno is another story, haha.

You didn't print off the a/f on Alex's car, so I am unable to tell you if it was at 100percent. He did some street tuning before it went there, and I think he said he added some fuel, so it was probably between 90 and 100 percent of where it was on our dyno. If you want to look at his A/F's on that run, we could get a better indication of overall.

Kyles car was probably slightly more off, but assuming the 18 percent drivetrain loss, he should have made around 575 on your dyno.

I'm thinking its more of a 15 or 16 percent loss though. Alex's car made 480 on our dyno x .85 (15percent) drops it right to 405.


Looks like on your 720whp pull on your dyno you would be making somewhere in the neighborhood of 830 on our dyno! Not too shabby.
