Are you considering a transmission cooler?

you should really have a trap speed of 110+ and be around 12.5/13 also with a bad launch.... on the road track you should be on par or really close to a 996 gt3 and an R8.... and that is even more impressive!!!!


damnnn 12.5? maybe with like a 2.1 huh? just throw some DR;s and 4.08 gears and youll give those cobras a run for their money

he quoted me.. I said on the straight... in the twisties is a completely different game. a GT3 is A LOT of car for a road course... an R8??? wasn't absolutely impressed... is more like a regular 911 that is nothing special.

at the end in an "amateur" driving world.. the driver still makes a HUGE difference on the track... no matter which car he drives.

I wanted some 4.083 gears but I was told I would need a new LSD cause I have an auto by Tadashi. True? And what are the benefits of a transmission cooler and how much?

you won't "need" a new LSD, but it would help alot from peg leg tire spins (stock LSD sucks monkey *****)

I think the pumpkins are smaller on the AT.

i know for a fact that the pumkins are identical cause there are interchangable, if there are any differences, then its whats inside the pumkin

I have changed alot of diffs and the internal parts out. AT have 3.3 gearing and 6sp have 3.5. This is because the AT has 5 speeds and the Manual has 6sp. the only difference in the spacing on the teeth on the pinion gear. Yes they are interchangable between diffs.

A.H. - Thanks for posting and helping all of us make better choices!

It helps keep the engine bay a lil cooler, increases the tranny's life, and helps hold the horsepower after some hard driving, and makes the transmission more efficient in getting the horses to the ground.

The more power you make the more stress you're putting on the transmission.

i sincerely appreciate the response....... last question for everyone, what do you ESTIMATE the increase in HP on a manual 2007 base?

im sure the answer will vary, but will it be close, more, just as close or way off?

Test pipes: 300 plus 150 install

INtakes: 539 plus 150 install

Pulley: 220 plus 80 install

Reflash and tune: 700


I know i pay a little over the usual for install but i like good quality shops working on my car and it gives me relief. This is basically what i paid minus the fee for the reflash cause i got that for free caseu i was a beta tester but since i had to pay to retune and do all those dynos i guess it cancells out. Plus you can still get my same power at a lower cost if you buy cheaper exhaust, i know the injen intakes are now on sale, and maybe buying used test pipes. I strongly believe however that my quality exhasut componets by Fast intentions and the inejn intake smade the most of this peak power and the headers smoothed out my powerband. The fact is the NA way on teh HR is not too bad for the amount of power you get for the money. How you get that power and what parts you decide to buy is all up to you. This is just the route i chose and the parts i used were the parts i believed would gain the most power and were off the highest quality. To each to his own

I think the 5AT found in the Z is relatively efficient, when compared to the 6MT. Since most 6MT HRs dyno around 265-270, and if you convert the 306 crank hp of the HR to the old standard, which is around 313-315hp, the 6MT has a drivetrain loss of anywhere from 14-16%. The 5AT HRs seem to dyno around 250-255, which under the same standards as the 6MT calculation just used, would represent around a 18-20% drivetrain loss.

On the OP's dyno, if all else were kept equal, and the only difference being the transmission, the 6MT would potentially read about 2-6% more. Anywhere from 6-19whp more. If you pick the middle percentage of 4%, it would equate to about 12whp. Keep in mind that this only applies to this particular dyno.

You need a Good set of cams, and with some good tuning you could see 330+whp. That would be so Sweet....
