i have a 98 t/a m6 with 44.xxx miles iam currently doin a winter engine build, it consist of prc ls6 2.5 heads 2.02 1.57 valves, tsp ms3 cam on a 112, ported ls2 intake with 90mm t/b, 42lb injectors, 1'' 7/8 long tubes, scorpion 1.7 rockers, and 4:10 gears, can some one give me a estimate on horsepower and torque, on a safe tune by cartek iam guessing 450-475 rwhp? any help would be apprciated, thanks matt

 

Feel free to post up results in the dyno section after you have them. This section is best for guesses and estimates.

 

I'd say somewhere around 420-440rwhp with an M6. That LS2 intake is gonna be holding you back some compared to a Fast setup imo. Its also gonna depend on which type of chassis dyno you will be using.

 

iam ditchin the ls2 intkae goin with a fast 90 now iam gunna do a lil port work to it also, its probly gunna be on a mustang dyno

 

They say a ported ls2 intake will flow just as good a an out of the box fast 90.

 

Who says that?

 

430rwhp. IMO.

 

Thats a great idea my friend Remember though that mustang dyno's usually read lower than a dynojet and or a dyno dynamics dyno.

 

im REALLY interested in seeing the results being i have the same cam, comparable intake and want to run the same heads, with by chance the same dyno your going to use...the anticipation is killing me!

 

in a month or two it should hit the dyno ill let ya kno wat she puts down, thanks for your intrest

 

thanks for the heads up, this will make or break my decision on which heads to buy next winter, thanks for the update

 

everything i've seen or heard is that the dyno dynamics reads lot lower than the others, in order from lowest reading to highest its dyno dynamics, mustang, then dynojet. that's why dyno dynamics dyno's get the nick name "the heartbreaker ". i know my tuned, 224 cam'd, full exhuast, bolt on's 02 camaro only put down 365rwhp on a dyno dynamics. that sucked.

 

You are right...But the few dyno dynamics dynos around here have been adjusted about 14% do be about the same as a Dynojet.
