IMHO, your power estimates look very optimistic. As others have mentioned he has an MT and weight advantage on you. I would call it a close race perhaps even an edge to him once the car is broken in.

Why??

He really wieghs that much less than me?

I appreciate everyones 2nd guessing on my dyno numbers.. I get dyno'd every few weeks-- never bother with a print out I just stand there and watch it...

w/e thanks for the input

yeah they weigh that much less, that's why z's avg mid to low 5's in 0-60 and 6mt's are high 5's.

Sounds like someone else has the fastest car in the "joint"

you have almost same set up as what i have, and i had a very similar race with stock 350z mt.

i won by about 1/2 car length. barely. the weight difference is a big factor. and show your dyno sheet. im kinda skeptical about your numbers as well.

I raced a supercharged m3 and he got about 4 or 5 lengths on me does that help
