Even popping the clutch at 4 grand, the car will still lay down and hesitate giving me 2.10 60 footers! I'm using M/T drag Radials set at 18psi. I tries moving the card accelerator pump cam to the #2 position and it didn't help at all. Best time on a 60 degree nite was 13.16 at 106 mph. Any help?

Do you have jet extensions on the secondary jets? If you like drag racing, support your local track.

BTW, there's a HUGE difference between yanking a motor down because the flywheel is too light or the gear is too high and a bog....... If you can't handle the truth, you're living a lie.......

If your bogging the motor because it doesn't have enough gear or power you need to leave higher or you will start breaking parts from the double hit on the driveline. If it's bogging because of a carb problem or something of that nature fix the problem and then you can figure out how high you need to leave but I'm sure it will need to be higher then 4000.

He'd drop the hammer at 6k and roll. Try going up to 4800. If it still bogs you might need to add some pump shot. Maybe add some timing too. That cam pulls from like 3800-6500.

If I can find it I think I have a vid of that car leaving.If I find it I will post it. God made cold beer,good friends,hot ladies and race cars don't spit in his face by pi$$ing and moaning about how life sucks!!!
