For you guys that have hit the Dyno making big power at what point did you have to go to 60lb injectors. I am maxed out right now with 60's and will have to go to 72 lbs. I have never dynoed but am making 18lbs of boost so really can't see how I need to step up more.
The fuel flow calculator on the Injector Dynamics website shows a total fuel flow of 288 liters per hour, which I believe translates to 57 lb/hr per injector (at 6500 RPM), so yeah, you are probably due to go up a size if you put more squeeze to it.
