22451, bigger injecter/fuel pump question. attn. Corbin Posted by toykilla, May-17-02 12:32 PM
Ok, as you know I am gonna try your 8 injecter setup. Im getting set of 8 injecters (all the same size for a mustang). With those injecters I need to equal 625cc's out of 4 injecters. I plan to run 4 with an AFC and the other 4 with the EIC that I ordered. What size injecters would I need to equal 4 injecters at 625cc's? I was thinking something around 400cc? Maybe even a bit less. Also, 110psi fuel pressure is with stock injecters and 9psi boost, 2 fuel pumps. If I increased the injecter size so much and added 4 more my fuel pressure should drop dramatically, even at higher boost levels, right? About what fuel pressure will I be shooting for with the setup im going?? Im gonna daily drive at 15psi and race at 30psi. I already have an aeromotive 1:1 fpr and stainless steel gas lines ready. also another gas tank that im placing in spare wheel well. im attaching a solenoid so at a flip of a switch i can start flowing cam2 into 93octane anytime i want and for any amount of time. what do you think of my thoughts corbin?

You've read my rant at the top of the 8 injector page. I really think the AFC throws off your timing. Thats why I've pushed this extra injector setup. I would really suggest that you keep the stock 235's in the stock locations and add 4 440's in the extra location. Set the fuel pressure to 50 psi at 0 psi boost (stock conditions) you will have access to 724 cc/min of fuel! Isn't that enough fuel? Just buy 8 42 lb mustang injectors and sell the other 4 (I know you can find a buyer). That will give you alot of fuel and only one fuel system to tune (no AFC). At 30 psi of boost, your fuel pressure will be 80 psi (50+30). You'll have to check if your pump is up for that. 30 psi is a shitload of boost. Feel free to run a spare gas tank with race fuel. Just consider that you have a return style fuel system. It cycles alot of fuel from the tank to the injectors and back to the tank. You may drain your auxiliary tank dry if you turn it on a couple minutes too early. Unless you have 2 completely separate fuel systems with pumps, feed lines, injectors, FPR's, and return lines.
