I'm getting really close to finishing my project, after 2 1/2 years in the making, and would like to get some idea's from you guys as to what you think it'll be like.

Exhaust -

There are still quite a few things I need to get for it. If I can get it running good, and don't put the time down that I want, i'll be throwing on some nitrous as extra fun. Don't know what i'll go though for how much though if I do.

I wouldn't be happy with anything less than a 10 second timeslip out of that setup.

Should be mid 10's if you can drive it...

I've got some learning to do in order to drive something like that, but I think I could make some decent times out of it. I am at 5800ft above sea level though, so i'd be happy with 11's. If I managed 10's up here, then i'd literally **** my pants when looking at the timeslip.

If I don't manage to get at least 500 to the wheels, then i'll be throwing on some nitrous. Otherwise, i'll be damn skippy with 500+ to the wheel N/A.
