![]() i have an 1989 vert with these mods, shortys, x-pipe, 65mm throttle body, 70mm mass air, 250lbs fuel pump and an powerdyne supercharger with 11pound pully.
1) Over the winter I have bought 30lbs injectors. I'm going to buy an adjustable fuel pressure regulator, what is a good brand to buy (if it really matters) and what should i set my fuel pressure at? 2) What should i set my timming at? 3) Over the winter i have also bought an victor 5.0 intake. Will this be too much intake for a stock cam and heads? thank you for your time and, any imput is appriciated! Last edited by 1_fine_89; 04-24-2004 at 11:33 PM.. |

![]() 1)IMO your gonna need a FMU if you wanna use 30lb injectors on your car. I'd actully sell them and upgrade to a set of 42lb injectors and ditch the FMU.
Kirban is the only way to fly when it comes to fuel pressure regulators. They're a nice high quality billet peice. Mustangwarehouse.com has them on sale for $67.99. http://www.mustangwarehouse.com/must...tegory_Code=HD 2)I'm not sure on the timing. A dyno tune is your friend. 3)Yes that intake is too big. Put it on a shelf in your shop till you've got aftermarket heads and cam. Or sell it and recop some of your money and put it towards a milder intake.

![]() I'll second the notion of 42# injectors and ditching the FMU.
Start with 10* timing and fuel pressure at 40 psi and work from there.

![]() Thanx for the info guys, but i think u have given me more credit than i deserve. I'm kinda a newbe when it comes to mustangs.
Why is it that i will need a fuel mangement unit with 30lbs injectors, and won't need one with 42lbs injectors? Does a fmu add more fuel as the boost gets higher? I no i will need to reca;ibrate my mass air meter for the new injectors. Is it hamful at all if u don't have the right size injectors? I havn't heard much about the fuel pressure regulator u have suggested, is it a well proven brand? I was considering a bbk, or accel? As for the intake i have decided to set it aside for now. |
