400 torque
Hi guys I don't post much on the forum because almost everything I ever needed to know was covered, but I would like to discuss the gtir weak gearbox case and get some input, I am just about to finish my ve head install along with a borgwarner 8375. The reason I went with that turbo was reading jpsr20 post when he made 5**hp on 18psi with his custom housing 8875. his torque figures remained in the low 400s. Miko a few years ago whilst discussing pulstars (red pulsar out of jam) build mentioned a gt35 usually has 75-90 difference between torque and horsepower and that when your turbo is to big for your target you see an increase in this separation. My previous setup was a t3/t4 50 trim on a stock gtir head @24 psi I did 11.7 in the 1320 @118mph with a horrible 1.9 60ft we have no 4wd dyno in Barbados and I estimate based on injector consumption and afm voltage the car was between 450-500hp, at that power level the car had to be around 400 tq, the box took it like a champ, all stock gear box with just 85-140 gear oil. I plan to brace the gearbox case shortly but I have no plans on a gearset. I was wondering how much hp do you guys feel is possible from a sr16 cam motor reving to 8700 rpm with 400 tq as the limiting factor, also is my 400 torque theory flawed with regards to box life. I also noted coheed stated that he started to kill P11 boxes around 400 tq. Any input would be appreciated.
