Dyno pull on monday 2nd or 3rd gear (results now in) What gear do you guys normally do a dyno pull at with these cars? 2nd or 3rd?
I'm going on Monday to do a few pulls and see where I'm at before I try a few other power adders.
Any guesses? Mods in signature.

Third gear. You want to have the transmission in a 1:1 gear ratio.
Guesses? How about 268 whp peak, maybe into the 270's, you ought to see a substantial improvement in the upper RPM range though, so if you have a stock dyno sheet, it might be interesting to look at the difference.
I think there's been a few people who have posted up dyno runs with similar mods.

I never tried this on my car but on th eold 4T60-Es if you unplugged the trans conncetor you would default to 3rd gear. Since this line pressure on this transmision is controlled electronially I dont know what th epressure would be, I'd like to thin k that it would be either max or mid. But furthermore the computer might protest in its dissconection...

depends on how much money you want to spend supercatxr7, mods from there out will require more money and and more time depending if you mod it yourself, if you want alot more power i would for the cnc 2.5 heads 5.3L from texas speed or the new weiand intake. i've seen where it should be out by the 15th. but like it said its more money

mine was 230.97hp 3rd gear pull with stock tune K&N CAI + magnaflow mufflers(was like 105 degrees that day :<)
Later on this year once the temp drops down into the 80's(might be November for that here in Texas) I'll run a dyno again on the car with the new upgrades. I honestly have no idea of the outcome since then it's been
SLP Rocker-Arm Package 1.85(rockers,springs,keepers,retainers)
3" catback with res delete still have the magnaflow muffles with 3"tips
ceramic coated headers&crossover pipe
flipped motor mount(will prob have ZZP by then)
K&N CAI(looking at a possible custom fender well intake for this atm)
head atm just have factory casting ground out and polished debating on attempting a port match myself just kinda tossing that idea around in my head while I wait on parts
still have to tune the car, I have the HPtuners software now just waiting to get the car back up and running.
also might have a custom 3" DP made with a electric cutout before the cat by then

If the run was done outside in that heat I'd guess it would not be too bad. On all my stuff when running at 95+ during the day and then driving with temps around 65-70 at night, makes me feel like I'm driving a completly different car.

I Did two dyno pulls at the carcraft show the first was with a k&n Cone with my aluminum airbox and i had removed the exhaust and Maf screen and bolted up a thrush turbo the first dyno pull chart looked really rough i think it was because of false knock because of the muffler contacting the tunnel. the second run was bone stock because i put the stock exhaust on and i had melted my intake from autocross the previous day its a pretty substantial difference check it out
