your claiming it won`t handle 650bhp how do you know ?? not asking wot you have read or seen, have you tested it ? maybe the turbo he has is right for the car and box , maybe your gt30r is to harsh for your gearbox, my t70 is i found that out also my gt35r , but things have to be pushed, otherwise you`ll never find its limit, its all down to luck and wot you want and how its setup, maybe he`s got it right and you`ve got it wrong or vice versa, no need either of you to be like this, i know wot he has, if he don`t wanna tell up to him i`m saying nothing but bickering about most power is nothi
