RE: More RPM from my 390

Well it has the same slicks now with 3.50 gears and it is faster.

I think it is mostly to do wht the fact that my car makes good power up to 4500 RPM but above that it falls on its face.

With 4.11 gears I was hitting about 5000 RPM at the finish line (somewhere around there anyway) and there just wasn't any power there.

Its not missing or anything like that, its just not making power. with the 3.0 gears I'm doing like 4200 RPM at the finish line and there is lots of power still, and with 3.50 gears its doing about 4500 at the finish, which seems about right for now, but not what I wan't, i need more power :)
Traction is still a bit of a problem, with slicks and 3.3 or 4.11 gears I'm averaging a 2.0 60' time with street tires and 3.0 gears it was 2.4, I did a 1.8 once on slicks but it was hot and they had just VHT'd the track.

I've tried different tire pressures in the slicks but the car seems to run faster the harder they are, even though I get a little wheelspin. I'm starting to think that my traction-lok isn't working very well though, I've noticed a few one wheel burnouts and I'm miffed about that as its just been rebuilt. I'd like a locker, but not a clunky detroit locker as I always thought that I had a broken axle every time I turned the corner :)
