I hear a lot of people talking about the amount of lag with a big single that can blow 650-800rwhp. My question is for street and road racing is the lag unbearable is it streetable. Is it easy to overwhelm the supra's traction at low rpm (1500-3500) or does this only occur at 4500rpm or more . I'm trying to get an impression on whether its worthwhile to upgrade to over 500rwhp. Basically is the power usable only at high rev's. Will I lose street starts.
