dyno was on a Mustang 1100SE dynamometer. I stated i was looking for 550rwhp and 500rwtq. i was informed that those number on the mustang would be around 470-480rwhp. after a few days of dyno tuning and work numbers were 462rwhp and 442rwtq. numbers were very close to what i was going for. the car has crazy torque and insane acceleration. meth kicks in at around 6 grand. car idles great and is very smooth. the stroker is even smoother than my stock ls1. very happy with the way the car drives and responds.

What are the specs on the motor? I thought number would be closer to 500...

backdraft408

number are over 500 its just the mustang dyno it was on. i know it has way more power then my old head and cam set up on my ls1. numbers on my old motor was 435/405 on the dyno jet. 460 on the mustang is about 540 on the dyno jet. motor is a tsp 408 with there 250cc ls3 heads and 239/247 624 624 lsr cam.

Why meth? CR? I dont see 540 with those heads and that cam. Maybe 510 on a dynojet.

All pulls were made with 91 pump gas

Very Nice. I have a similar setup I will be putting together this weekend. Hope it comes out as good as yours

backdraft408

what set up are you going with?

30th t/a

Agreed.

Ive done back to back testing on a Dynojet & Mustang dyno and they were within 3rwhp of each other. Mustang dyno reading vary too much. If you want Dynojet number, put it on a Dynojet.
