Take the car to the track, and then see how it performs.
Take my car for example... a stock LQ9 truck motor with an EPS cam, dyno'd only 388 rwhp through a redneck racing 4,500 stall and a TH400.
Even taking it pretty easy at the track my 2+ ton car ran 12.0@111mph... using the Wallace Racing Calculator it shows the car is making closer to 415 or so to the tire.

You guys really think I can gain 13hp from just a lid? I'd love to hit that magic 400rwhp number but I don't know if it's possible. My engine mods are basically done at this point, there's a 75 shot of nitrous going in ( already have the kit ) and other then that I don't have any plans.
and don't focus on the dyno #s too much.every dyno reads different.the track is the real dyno.
