So i'm saving my money and planning on getting a Kenne Bell for my 'stang by summertime. What # injectors should I use? I am planing on running 8-10 psi and was thinking 32# Injectors. Also how big should my throtle body and MAF be to compliment the supercharger? Thanks.
Go at least 42's. When/if I ever get mine going with the Vortech, I'll be running 60's, plus a 255lph in tank pump, and a Vortech T-Rex 255lph external. Overkill? Maybe, but I'd rather not lean out.
if getting the car tuned (highly reccomended) and are planning on increasing power (which you probably will by cranking the boost up) then i would say 42s at a minumum, i'd even go larger. 42s can be tuned for with a good tune and idle and drive awesome, so there isnt a reason to not run the larger injectors, get a big pump also. mustangs have a return line so getting a large pump and injectors is the best way to do. dont use the FMUs, they work decent but its a hack way and just not the best way to do things.
I agree with the FMU but in my case i have to use it till i can get money to do they next step..Im going with the Kenne Bell and im going to use the FMU and i am going to install a 255 lph pump right away, Then in a few months i'll go with injectors and A Tune this is my daily so i have to do it in stages...
Im going with the Kenne Bell..I was told yes you need a bigger fuel pump and should get 42# injectors and a MAF to match or a PMAS...But its not needed until you go higher then the basic kit which i have no plans of doing ...im staying at the 5-6 psi kit...so im going to get a wide band Air fuel gauge to make sure i dont go lean under full Thorttle...I might do a dyno tune down the road but KB and i talked to a few tuners said i can run the FMU it might run a little rich ..set that spark plug gap at .030 bring the timing back to 5 degress well start there and use at least 91 octane...so thats what im going to do for now until i have funds to upgrade...
