suspension and ignition setup need help

Yes. That was last summer at englishtown. Much appreciation for all the responses so far.

Wow. lots of feedback here. Front springs are Santhuff 250lb. rear springs are stock. Front shocks are QA1 single adj. Rears are QA! double adj. Adjustable upper arms are technically not within the rules but are not enough of an infraction that anyone complains. 6 inch rims are all that's allowed but most racers run 7s. The basic premise of the class is that the cars appear stock to the casual observer. I'm running a turbo 400 with a 2.10 first gear with all light weight internals as well as a 12 bolt with 4.56s with a spool and gun drilled axles.

I leave off the foot brake at 2000 rpm pulling out 15 degrees of timing for 1.5 seconds.

It sounds like you are pretty much maxed out given the restrictions. I agree with Alan about testing the limits of launching be it thru timing events or other means. The testing never ceases for any of us...

Another engine builder, who is a friend of mine, and responsible for some historic performance, told me "it isn't so much that we know what makes the car go fast, it's that we know so much about what doesn't make it go fast, or even makes it go slower". All of that comes from testing, relentless, exhaustive, tedious testing. Unfortunately, there is no known substitute.

Four wheel scales? 50/50 or better? Just some things to think about.

After giving this some thought I maybe would be inclined to look to the other end of the track instead of beating a dead horse....err, tire I mean.
