#N:gummo:29900002:000:332 gummo!thy Apr 28 21:25:00 1984 a little more info on the '85 Vette! the fuel injection system that will be used is called a port injection type. fuel is injected directly into the cylinders which eliminates any power that would be lost in the intake manifold (plenum). in '86 rumor has it that the vette will be running a dual port injected engine (mucho hp).

Directly into the cylinders? Would be nice, but not trivial to do. The injectors would have to handle temperatures of over 1000 degrees F, and pressures in the 150 psi range. And not fail due to deposits. You also need a fuel pump that does well over 150 psi. "Normal" port fuel injection injects not into the cylinders, but just ahead of the cylinders. The injector sprays towards the back of the intake valve. Life is a lot easier for the injectors, and the fuel pump needs to put out 'only' 50-80 psi. "dual port injected" ??? what's that?

Port injection puts the fuel into the intake port just ahead of the intake valve not directly into the cylinder as in a diesel. It is much better than throttle body injection anyway! Keith Bauer White Tiger Racing
