Hi all, first post,
I too am running a Race Truck with a 855ci Cummins Engine, compound turbo setup 75psi boost at intake manifold,
Max RPM 2700- 3000. WI switched on at 40 psi . One 0.8 jet @ 100psi right after the IC, has dropped intake temps from 107 deg C to 60-65 deg C. Exhaust pyro temp no change 550-600 deg C.
My question is, would 3 jets in the manifold be better with a 50/50 % Meth mix ?
What position is better in the manifold, firing at the cylinder head inlet port or at 90 deg to the air flow ?
What is the formula for calculating air flow etc, for this engine, i have looked at many web sites and they seem to differ ?
Any help would be great.
