I run 275 40 17's on my street wheels, and 28x 10.50 x 15 slicks on my track wheels.

3.55 gear out back

Spool is great. I'm in full boost by 3000 rpms. Granted its 5#, but thats where it comes in at.

I love this car! I think I fist saw it on a 1320 video, but I'm not sure. It looks the same. Been wanting one ever since! I have a 00 z28 I'm trying to get rid of to get me a Z car. I'm keeping the ls1 to rebuild and drop in when I get my hands on one.

Just blew the HG in my setup, thought I dont' think it had anything to do with timing. Depending on the cam 14-17* or so seems to be the standard for most on E85 and 10:1. I have peak torque around 14 and ramp up to 17* after 5500 or so. That was 25-26lbs. I run 50/50 meth inj and a cheap A2A IC.

Any updates? I'm sure you are busy enjoying all the hard work you've done. Did you ever make it to the dyno?

I have been enjoying it. It keeps chucking belts, so I'm getting a billet tensioner. Should be here this week.

No dyno yet, still working on other things with the car. I have been creeping up on the boost, but the street tires make for a wild ride!

Been there, done that. Pulled him on 13#.

Haven't visited this thread in a while. The trailer sat for a year, but I'm about to hit it hard again with drag week looming in 3 weeks.

Pulled the box off it this weekend, and started measuring for the axle, frame, and rolling stock.

This is very close to the ride height that it will be. For reference, the top of the bed is 33" off the ground
