Anyone have tips for the Pro Tree (.4)

[JekylandHyde]

Last year was my first year dealing with the Pro Tree and I do okay, but I was not consistant with my R/Ts.

Any tips or suggestions?

I am assuming you have a manual trans. Are you just sliding your foot off the side of the pedal or do you slip the clutch ?

If #1 then you can either adj the clutch so it engages just above the floor or put a block of wood under it so that you don't have excess engagement before it hooks up.

If you are slipping the clutch I don't think you have a chance of being truly consistent.

I always wished Atlanta Dragway had allowed the racers to select the tree they wanted. My last car would have been great on a .500 pro tree. I would have started running Pro against the delay box racers.

With my high rpm, boosted launches ... I do have to slip the clutch to get out of the whole without bogging or spinning.

You need to turn the motor around and move it up front . Then hook it to a multi-disc clutch and a clutchless shift tranny or a stout auto.

I used to do some "mental car building" using a turbo 4 cyl Fiat twincam. Icebox intercooler, EFI, twin injectors, hooked to a powerglide w/transbrake and with a 2.06 first gear.

At the line I would floor the pedal to get the boost built up against the torque convertor. Have the onboard comp limit the start line boost to about 10 psi. Let go the transbrake and the motor would quickly build boost to about 20 psi controlled by the wastegate. I think the 2sp tranny would keep the motor under a lot of load which would keep the boost up.

The car I envisioned this in was a miniature Brogie Roadster weighing about 1000 to 1200 lbs. Or a 150 to 175" dragster.

For your problem I used to envision an adjustable shock absorber hooked to the clutch pedal. Side step the clutch pedal and the shock would control the clutch engagement.

Get too aggressive and you will be breaking halfshafts and CVs.

A buddy that used to crew a small, independent Pro Stock team said that they used a multi-disc, small dia circle track clutch. It would slip a little on the launch and hooked up good after that. Required very little maintenance.
