Fuel Injector Size HELP!!

Duane Eiskant · 01-30-2012, 07:27 PM

I hope this is an acceptable post?
I am currently working with a friend on a 2010 Camaro street car project that will see a small awount of time at the dragstrip. We have a LS based 427 cubic inch engine with a F1C Procharger that has a 92mm throttle body and a Fast LSX-R intake manifold. It is a pump gas engine with a 560 lift, 232 degrees duration at .050, Comp Cam and All-Pro aluminum heads. Boost will probably be in the 15 to 20 psi range. It will be tuned with HP Tuner through the stock ECM. Any suggestion on a size for the fuel injectors? I know its not stock or super stock, but there seems to be many knowledgable people on this site that I know can give accurate suggestions!
Thanks for such a great site, Duane

I have no idea but Ed Wright of Fast chips is the man to talk to. Throw that HP Tuners stuff in the trash and call Ed. I would bet with his tuning it runs faster with less problems. I dont even waste my time fooling with mine when I make changes. I just box the PCM up and send it to him.

Thanks Rob. (blushing)
Duane your going to need about 75 lb injectors. I have honestly never tuned a 20 psi 427". Should be a beast. Good luck.

Duane,
Ford Racing offers an 80 lb set under the part number M-9593-LU80.
regards, Roland

Those should be good.

Again, thanks for a great site! Duane

I just wish you still had the chassis dyno. Best money I ever spent.

Duane its your fault I even know Ed. If you had not told me to take my car to Midnight madness all those years ago at Calhoon's it would still be bone stock and I would not have needed his help. I would still be trying to kill myself with that boat I had. I will admit I do feel alot safer at 135 in my car than I did at 135 in that boat. LOL. His number is on his site Fastchips.com
