So-so night at the track....
I went out last night to try and do some pre-N vs. S tuning. I wasn't able to add any weight to the car yet, so I'm still under the 3200lb. minimum. Traction was pretty much non-existent, even on my "monster truck" 29.5x10.5 tires. I spun some on every pass, and my 60' times were off by .05 or so.
I was planning to do a little fuel/timing tuning and eek a little more out of the current combination, but on the 1st pass, I lost a damn muffler! One of the brackets that I have welded to the muffler (that makes up my ghetto hanger) broke off, so I dragged the muffler all the back to my pit spot. You would've thought I had broken the crankshaft or something from all the noise it was making with the muffler dragging along the ground.
Overall, the car was running pretty good despite the heat and humidity. The best pass last night was a 10.09 @ 132.5mph, but I don't think there is any more in the car until I upgrade a few parts here and there. A nice new set of bigger headers would probably be a step in the right direction. Maybe one day...

Re: So-so night at the track....
What rpm are you leaving at? Do you have a tranny brake or are you just using the stall?
When I footbrake the car, I stall it up to ~2800rpm or so, and when I use the t-brake, I usually have the 2-step set to ~4500rpm.

How far under 3200??
My guess would be around 3050lbs. or so right now, but that's a wild guess. I'm going to fab up some bolt-in ballast before Saturday, and go do some testing @ ~3200lbs. in the heat (Saturday is supposed to be 93deg!!!), then leave the car alone until the BG event.
