HP Level To Max Out 60lb Injectors?
This was of course done on some kind of closed course.
It looks like these 60lb injectors would be maxed out or close to it without the meth injection. It seems like based on the injector duty cycle on these 60lb injectors a decent hp estimate could be achieved. I just don't know the formula. Even with perfect math it would still be off since a 50/50 meth/water mix is being injected at the same time. I would just like to hear some educated guesses. I will be hitting the dyno up this week or coming weekend anyway.
This is a stock bottom end ls6 with a 218/228 cam, 1 7/8" LT's with hi-flo cats, and the stock TI catback.

One more factor is your fuel pressure at high rpm, max boost. If you don't have a good enough fuel system to support your setup and are compensating with an increased pulse width, then it will skew my guesstimate numbers. I will guess 575rwhp. You tested this at TX2K9 right?

Well, I do not have a FP gauge inside the car. I could tape 1 to the windshield and probably will during the dyno. I have the racetronix pump, hotwire kit, and KB BAP. It gets richer when I increase VE so I'm not too worried about that part.
TX2K9, yea, that's where I did this
I'm expecting much higher numbers, but we will see.
