Here is the best time slip from my test and tune session last sunday. Launch was at 2000rpm so 60ft is pretty terrible. Even with the restalled converter, the brake can not hold the car back. I could not do burn out either since the brake is too weak. The slicks slip a bit at the end of 1st gear. The tach needle never left 7500rpm after each shift. The gear change was so quick, the car did not jerk at all. In another slip, the car did 112mph with a 7.6et.
I recent went to an automatic transmission. The tranny has the Kiggly's 5 discs front clutch pack, IPT end clutch, translab valve body kit, B&M Pro Ratchet shifter, and restalled stock converter. The car made 400hp and 317tq on the dyno last week with this auto swap. That are about 150hp and 150tq less than with the manual. Yike! I did not do the valve body mod when I dynoed it so it might be slipping the clutches inside due to not enough line pressure. I am not sure and will be heading back to dyno soon to see for sure. The run at the track was with the valve body mod. After reading about similar lost in power and torque, I believe it is the restalled torque converter that is sucking up all the power and torque. According to what I read, restalling the stock converter cause it to be less efficient. Most non locking torque converter can only transfer 90% of engine tq to the tranny. A poorly restall or poorly design converter can transfer even less than 90%. I believe my restalled torque converter is on the ultra low efficient zone. If the slipping clutches is not to blame, I will switch back to a bone stock converter and redyno. I am hoping to gain back at lease 50-70hp and tq which might put me in the high to mid 6s 1/8 mile.
I also want to step down to a smaller turbo to run with the stock converter so if anyone want to buy a near mint gt35r, please let me know.
