One of my goals was to get it on a scale at one of the tracks last weekend, and that didn't happen. Not a clue, but it's less than stock. Aluminum headed engine, fiberglass front and rear bumpers, no heat or ac, aluminum wheels, no front sway bar. And don't get me wrong, I'm happy as a clam, but I can and will do better.

I participated in the Northwest Nights Motorsports track event at Bremerton Motorsports Park this weekend. Pulled into the pits late Friday night and set up camp. It was cold. Here's some views of the morning.
And my camp.
Ran close to my best on Saturday, but only got two runs in. I was concentrating on getting my nitrous system wired and functional and logging the runs to verify the tune.
Sunday morning:
It was slippery!
Pedal, pedal, pedal....
The important part- it all came together in the end and I ran a 10.98 on a 100 shot.
And a snapshot of the log of that run.

Thanks! There's a couple of things I wish I had different, like 1-7/8 headers and a billet 3,800-4,000ish triple clutch converter, but I just don't have the budget. And the smaller cam and tighter converter are compromises that make it streetable, but leave a bunch of power and ET on the table. I also went with the cheapest head solution out there with the PRC 5.3L, and they made a bunch of power, but hold back even more than if I'd have used a more expensive head. In the end, especially with the nitrous, the car is quick enough to need a cage now.

I know what you mean. I have a bunch of comprimises too. I got the biggest cam I could get without flycutting. Would like to have an aluminum block to drop more weight and some higher compression. I'm gonna do the 1 7/8" headers off the bat, along with a pretty radical converter. Maybe once I get my setup dialed in, I will have my truck and student loans paid off, and can go forged internals, fuel injection, e85, and turbo.
