I may be wrong (hope I'm not), but I thought this would work for a GC-type. I am under the impression that it would work for the 00 & 01 RS's - EJ251, MAP based, 3 plug ECU - even though their development car is an '05?
Do you know the stock injector size? Since I really wouldn't want the injector duty cycle to go above 80%. If anything I would actually recommend welding injector bungs into each runner of the intake manifold and then splitting it with a 4 way fuel block.
Also wouldn't there be a code thrown due to the fast MAP rate for different throttle positions? Like for example once the S/C starts to spool the ECU will only see 1 bar max BUT at say 25% throttle the MAP reads 88kpa when it normally reads 65kpa (N/A) my old saturn threw this code when i boosted it. (Some sort of MAP High / MAP Low Code)
Just wondering if Raptor
The injector duty cycle, I cannot remember, I will go into the ProSequential software sometime and check it for you. The answer right now without looking, there is WAY more fuelling capacity there than we can use at the moment. The only issue I have noticed was during hard cornering with 1/4 tank of fuel, the fuel sloshes away from the pick up and pump runs dry. This will be normal for this model car and is something people need to keep an eye on if driving the car hard.
To those people wondering about 5th injectors - Raptor SC does not do 5th injector style fuel systems, its either correct sized injectors with ECU management or nothing.
