Racers
This season I am hoping to move up a class at our local track. The class I raced in upto now used a .5 pro-tree. It took a whole season but I finally got the hang of it. The new class uses a .4 pro-tree. My question is do you think I can get my car to react fast enough? I have upgraded the engine to a 512 with a [Email]262@.050[/Email] solid roller. Same 5000 stall,4.10,t-brake, with Cal-tracs. Last season I could cut a pretty good light but was red quite a few times (.008-.010) Will the mods over the winter make up the difference?
Thanks
Dave
It's 268 @ .050 Dave

Well if you are allowed to deep stage per the rules seems like the best way to go. If not limiting travel, shorter tires, higher launch rpm, more gear, more converter and practice practice practice.

As already stated...small tire, High pressure, tie down the front suspension and leave against the converter (no two step)

Put the smallest front tire you can on the car...set the front tire pressure at 45#....and if you have limiters on the front suspension get rid of as much travel as possible...or tie it down if you don't have limiters..
 If that's the route you go don't try to deep stage. The idea here is to LIFT the front tire out of the beam as fast as possible. If you roll in you have more tire sidewall to lift out of the beam.
If you tie down the front you still need to have a couple inches front end travel to get the thing moving up. Then you probably need a pretty good shock to keep the front from bottoming out and bouncing when it comes back down.

I know it's gonna be tough but I will try anyway. If it turns out bad I can always slow it down and run in my old class.

The new AHRA rules(draft) had the GAS (10.90) class running a .400 Pro tree. One of my comments to the rules was that for the grass roots racer that they are after many would not be competitive on a .4 tree. I hope they change it before finalizing the rules.
it makes a whole lot of cars unable to compete.

IMO depends on the rest of the rules in the class. Weight, chassis type etc. IMO if it is a stock suspension class with a fairly heavy weight I dont see why it would be an issue, keep the playing field level IMO. Now if they allow cars like mine, meaning tube chassis cars, with boxes I dont think it is a step in the right direction at all.

Somewhere between 400 rpm less than stall speed to just pull the chip out and go against the converter for your best leave on a .400 Pro Tree. My 400 is chipped to 6200, shift at 8200, I can red a .400 Tree if I really want to.
