New project

Do you leave off a trans-brake or foot? If Trans why not try an adjustable button?

Looks like its running good HotRod. How red are you going? Arent you already using an adjustable T/B switch? Can you fit a taller front tire? Questions questions lol

Going to try a set of 26" fronts also . That right lane is still messed up and nobody will fix it . Hopefully after the national nhra will fix them .

Just almost too much work Truck has been on jack stands for the last 4 races . This weekend was no different . Guess I missed tightening a head bolt and had a water leak . It filled the diaper up with water and one of the header tubes burned through and found water . Had to drop the exhaust headers and front crossmember in the pits to get it off before first round . It was full . Found the leak in a head bolt and tightened it . Water leak stopped . I actually lost a round last sunday other than that red first and second round . On a good note swapping to 76% made the truck A/F ratios perfect and very consistant .

Hotrod It looks like you may be yanking the front tires out of the beams. If you have an adjustable front ladderbar crossmember you could try lowering them one hole. This should make the truck move forward more instead of upward. Or like you said change the launch rpm( I move mine as much as 600 rpm throughout the year) because i do a lot of my setup by 60 ft numbers. I dont know that there is still a problem with that right lane. NHRA sets up our stuff starting on Fri morning at our races. Hence my numbers in my delay box are .030 less from the TNT numbers on Thursday(local track setup)

Im leaf spring and Caltracs . So changing pinion angle is a no go . I am just thinking im gonna try moving launch rpm and tire pressure together . Say 36# @ 3600 rpm if im late i'll go 3700 and 37psi and so on . Im at 4200 and 44psi now .
