Dave from memory the FD weighs about 1180kg, Winton was good but the 3 consecutive hairpin style corners just destroyed my lap times as traction was non existant on exiting them, Im hoping the Mfactory LSD aleviates this. max boost is 7psi, plan is to do 5 or 6 more track days this year and then turn the boost up to 12psi, 15 psi is about the limit the motor can handle from what Ive read, thats should deliver me around 230kw's atw !! Motors are dirt cheap some Im not too worried about destroying a few ... lol
