If he only has enough mods for that much power you will smoke his ass, but I never admit how much power my Z has for the same reason. I just smoked a mustang yesterday but have also had my ass handed to me by a ratty mustang with a huge rumpety rump camshaft and open headers(gotta love that redneck sound.NOT). Just race him AT THE TRACK. There is a memorial about five minutes from my house where a guy named Big Lee DIED in a street race, and a dude in a camaro was beheaded going under a semi at another spot we used to race at. If you insist on street racing, do it right. Buy scanners and have lookouts, not for just cops but for vehicles that may get in the way. Have someone at the other end but OUT OF THE WAY!!
