Fuel Injector Size HELP!!
 

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.

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

You also need to look at the stock fuel pump. I installed a LSA crate engine in my 2010 Camaro a couple of years ago. We used the CTS-V pump and controler from Lingenfelter.
We made 14 pounds of boost and ran 62 pound per hour injectors. We ran them at a system presure of 58 PSI. They were rated at 43 so we picked up a little flow.

Car ran 10.33 at 132. Horsepower at the crank was about 750.

Thanks Robin, the car is equipped with the Lingenfelter stuff! Would it be OK for me to give you a call?
