CAMARO6 - View Single Post - Port Plates- Injector Sizing

AC Promotions · 03-10-2023, 05:37 PM

I have a stock dry sump LT4 with a Harrop 2650 and the newly released Harrop port injection plates. They are similiar to the Too High PSI plates except they are located in the valley plate and take the short EV14 LSA type injectors. The question I have is that if I run the stock boost level of 12 psi and target 750 wheel horsepower on 93 octane or E-40 what size injectors should I be looking at when using the Reflex + system?

And yes, this is a Pro-Touring build but just pretend its a stock ZL1 LT4 with Too High Plates and a 2650. It does have a LT5 throttle body, 1 7/8th inch custom headers, high-flow cats (and test pipes for road racing), full-3" exhaust and a Magnum F. The object is to run a bigger supercharger at low boost so this almost 4000 pound Lemans can run long road courses without cooling or fueling issues. The fuel tank has twin ZL1 fuel pumps.
