Screw Blower Dillema

If you got a MOD-MOTOR and you put a screw or a roots on it your got real problems with the tune up. The computer doesnt like um a-tall.

Here's what we have to do to get the tune up fixed.

1) Get 30 lbs injectors
2) Change all fuel lines to larger
3) Take the pump out of the tank and throw it away & get an external pump and adaptor to go in the tank it takes (1/2 ID Inlet line) 2 190 Z-Rex pumps hooked together with 1/2 inch OD fuel lines going to the engine.
4) Now you have to add 3 or 4 injectors to the top of the blower to get it to idle properly and take throttle at low rpm's.
5) Ignition Timing is very critical so find a chassis dyno service to help you solve that problem.
