Gearbox Limits

[ajcluck]

hi all, can anyone tell me the torque limits of my gearbox on my st205?

[GT4 BOOSTER]

i think its 350 to 400 bhp and it dies.

oooh, i was expecting it to be a bit higher than that, was looking at about 450bhp with 400 worth of torque with all the upgrades i have done.

Just for future reference, i phoned up fensport and asked them about the gearbox, and they said they have used a standard gt4 gearbox to well over 500bhp, they never mentioned any torque figures but i am assuming it will be over 400.

[GT4 BOOSTER]

didnt fensport only do a few 1/4 miles runs at 500 bhp though , and the gearbox exploded. its not really for conventional everyday use . ?????

haha, they failed to mention that bit! i know there is a few ppl on this sit that are running over 400bhp in thier gt4's, what gearbox are they using?
