Your thread inspired me. I went out and G-teched new combo I am trying on my 88 shelby Z (auto, stock intercooler, mitsu turbo,5th injector, 15# boost) [email protected]
Launched at 3# boost,backed out of first spinning.

Your's has a lot more in it. It is just going to take some work to get it out of it. Mine before with a t3t4 at 20# went [email protected] with a five speed.

Good luck and enjoy.

Just a thought, would launching at a lower rpm help? something like a 2500 rpm clutch dump vs a 4000 rpm clutch slip? just wondering..

Getting an accurate 1/4 mile without slicks is useless. On a street with street tires all you do in first and second is spin. So to get a half descent time you have to feather the gas which is costing you time. Get some slicks and at a drag strip you will definately get more accurate results (something worthwhile).

Oh, and to answer this. Launching at 2500 you'll probably just bog really bad and fall flat on your face. That's why turbo dodge's are so difficult to launch. And once you up the power it's almost impossible to get a good launch unless you have really good tires or slicks.

:thumb: thanks very much.. i figured dropping the clutch where your TQ is made would help with the "go" factor and help reduce wheel spin.. but as ive just read.. useless! :D

Im running the RP performance stage 2 clutch, the 4 puck one so its really hard to slip it to get a better launch.
If i had a stock T3 turbo i could launch at like 3000 but the super 60 needs a second of full throttle right at the launch to get it making boost. Otherwise i get about 2 seconds of "civic like acceleration" before the boost ramps up.

And yeah with the setup it pulls to about 6300, when im spinning in 1st/2nd doing a pointless burnout for show purposes its really easy to make a huge burnout if i keep it floating a bit above redline.

I'm just curious as to why your revving to 6k in 3rd and 4rth? I could see 6k in 4rth at the track.. but 3rd? I realize your car isn't stock though.. so does it still pull that high? I know mine are done by 5200-5300tops.
Even if you're out of your power band that high in RPMs in 3rd, shifting at the highest point, you're still making more power than at a lower RPM in 4th because of power multiplication through gear ratios.....plus, shifting at higher RPM in 3rd will make your shift to 4th right in a good part of the power curve.

Bad traction, agreed (as he stated that he feathered the throttle through 1st and 2nd gear). Also if it's the G-tech pro (not the latest one) it gives you a higher mph then if you were at the track.
