What size injectors for up to 1000 HP?

RC000E

95lb/hr at 80% duty cycle will cover 1000hp at an estimated BSFC of .60. In the real world, I've used injectors smaller than what typical calculations call for, but having a comfort zone duty cycle wise, is always a good thing.

I agree with RC000E but since I always like to have some headroom, I chose 120lb/hr. injectors for my 1000hp project.

I am running the Bosch 160 #/hr, but have been looking to upgrade to the larger Siemens units (may make a run on E85). The 160 #/hr will support way more than 1000HP on gasoline.

I ran the Siemens 84#/hr when I was exceeding 900WHP (which is past 1000FWHP). It was only when I upped the boost significantly that I moved to the larger injectors. All of my injectors are low-impedance.

Corn fuel is the way to go. Been running it for 3 years now in my car and never looked back. The torque, reduced spool time and clean burning nature....all good things. Stuff is a little pissy at leaner mixtures and lambda values that don't seem to misfire on gasoline, but aside from that I'm loving it.

I enjoyed the attention at the E85 pumps originally, but now it's more of an annoyance. I had a Sheetz employee running outside towards me waving arms like I was destroying my car. I explained to her why I was able to use it, but regardless the other people at other pumps got a good laugh like I was an idiot. I gave them some 3 gear wheelspin when I left. I thought some of them might pump it in their own car seeing how well mine apparently ran on it..haha.
