I had my brother drive the sc400, (my bro weighs 390lb,, huge guy
I pulled on him about a car and half up to 110mph or so,,,,
given that weight differances on drivers 150lb vs 390lb
i think the sc400 is right in the same power and speed range as the g35...
note my sc is modified i put down 230lb of torque and 207rwhp
have not clue what my g35 puts down,,my mods on it so far are a cold air intake......
also 0-60 times, on lexus sc400 best 6.45 with g-tech,,,15 sec 1/4 mi
with G35 i got 6.38 0-60 with G-tech. 15sec 1/4mi
