Drag Racing Frustration!! Car Trouble
Ok, I am a typical guy and I hate asking for help, but I am totally dumbfounded. My car has an odd problem and any suggestions would be great!
I can make three perfect burnouts (Usually) then the third run it begins to mess up. When I am at the line waiting for the lights to finish the RPM begins to drop. My foot is in it all the way and I am against the Trans Brake at 5500. By the time the light goes green it nearly idles off the line. Then about 10 to 20 feet out it runs like a bat out of hell again.
I have replace my fuel Reg, fuel pump and it still does it. I was grabbing at straws and put in a new converter and it still does it. The motor is has only 15 pass's on it and half of those were with the wierd issue. I rewired the car etc. I am about to freaking lose it! Any help out there? Hell, and witch doctors out there?

I never thought of a cell problem. I run an 5 Gal RCI. Heck I am willing to try anything at this point. I appreciate your help. The cell has been the same one I have ran for years, what could go wrong with it? Kind of funny, everytime I think I have broken everything made racing I find something new to bust. lol

Are you running alcohol?
Injection or Carburated?
If alcohol, when was the last time you cleaned out your fuel filter and blew out the fuel lines?? Removed and cleaned the injectors?

It is an 1150 Doninator on gas.
Checked the vent line, it was plugged up with a little crap. But took it out and brought it up against the converter and brake and it did it again. And my daughter wonders why I am losing my hair!!!
