New LSX dyno #'s I brought my car to the dyno and switched out the 78mm LSX.After doing 8 dyno pulls with the LS6 to make sure I tuned for the most HP I switched to the LSX.Then I tuned the LSX for the most power.
Before # 421hp/388tq
After # 432hp/394tq
There was hp and tq gain across the whole rev range.I have the dyno sheet that will be posted later.All in all I'm very impressed with the power.From what I see the TB is a major restriction.Can't wait till the 90mm version.I definitly feel a big difference in drivability,much crisper throttle response.
Mods
MTI lid
ported MAF
ported TB
TR236/230 cam
ported LS6 heads 2.02/1.60 valves
ASP pulley
FLP headers with ORP
Denny's nitrous driveshaft
Strange 12 bolt with 4.11's

Thanks for doing that testing!! I wish you had access to a 80mm TB and could stick that on there.

We played around with a few things.We pulled the Lid and gained 4hp which I didn't get when the LS6 was on there.
Also all runs were done with the engine at 170 degree's for even test results.

Thanks for the independent test!

Not the best of numbers, but many of us spend $2000 for 30-40rwhp on heads, which is the same bang for your buck.

Yeah, if your going from a LS1 intake, It might be something to look at, but theres no need to upgrade from a LS6 quite yet.
