In the mazda (stick car) it was setup with a stage brake and slipper delay valve. We launched at around 25 PSI loaded on the brake full tight clutch no delay. We also dabbled in 30 on the 3 step. No load, clutch out with a magnus clutch slipper valve. Motor went south before we ever got any good data.
this was all footwork in a car driven to the track.. stock 94 econoline bottom end cast pistons and all. nothing fancy cheap promaXX heads and mild cam. trapped around 145.. in the 1/4 not bad for what it was.

now I am helping him dip into the 7's in the 1/4 with the same car but dart block, still driven to the track E85 and 21psi but auto this time. he has to get the safety equipment in the car to go any faster.. it has ALOT more in it

You think building a racecar is expensive....until you get into the safety stuff. Then it starts to stack on lol. Cages, chutes, harness and neck support, helmets, etc etc.

Turbskis are in. And elbows. Need to cut the headers back, cut the elbows down and get welding.

Nice. Build. Are you going to keep the N-41 cam in it? If you're swapping cams I'm definitely interested in it for my 331 build. Thanks.
