Nice torque and hp almost same now. Funny how sometimes see lower torque and sometimes higher on these various turbo dynos. Wonder what the secret is to have higher torque than hp? I always thought having bigger engine like our 402 or 408 or even bigger was the reason.

Anyway nice to see some LG builds getting dynoed now.

Good #'s but why are you only turing it 6200 RPM?

I dont see numbers falling off. You can lose torque and still gain HP. If it keeps the same power all the way to 7k thats where you shift it.

Exactly..6200 for a 402 with a turbo isn't shit.....
IF it's not carrying the power something is up...it should carry to at least 7k. You wanna shift a few hundred RPM AFTER peak. Not to mention i never saw if falling off really?

Good numbers wonder why your power stops climbing so early. Around that RPM is where my inlet ducts would suck shut. Did you have your ducts on or off?

tranny definitely beefier than the T-56. Gear ratios better spaced. 6th is not nearly as much of an overdrive. Went with TR6060 because I was afraid the stock T-56 after the abuse so far wouldn't hold up.

As to the power band. Replaced the inlet hoses with heavier duty wirewound silicone. Don't think they are collapsing. Restrictions I now have are the stock LS1 Throttle body and single borla exhaust and QTP single cut out. When next year comes I will get it retuned. (This car has not been retuned since I had the original turbos and LS1 intake). I suspect I can get more out of it with a full tune. I may have to upgrade the 60 lb injectors. Weather has not been good enough to check their duty cycle.
