meh, i think it's a drivers race.
you can't just look at hp and tq figures to see who will be faster.
first off, the si is lighter.
and also there are two main problems with being autotragic:
1) you have more drivetrain loss, so you don't have all that much more wheel horspower than your friend.
2) gearing.... i've seen vids of auto SERs accelerating and they hit a wall when they hit their 3rd gear....
it should be a good race though. btw, i think you can floor it before 4000 rpm w/o spinnin.
