help on injectors and fuel pump.

i have stock cobra injectors 24# and stock fuel pump. putting in a p1sc procharger kit was used and doesnt include fuel pump. what size do i need to upgrade to and will my stock 24s be big enough.

The 24#'s should be sufficient,as far as the pump goes,I'd say at least a 155 lph,but I could be mistaken on that one.Are you running an adjustable FPR?

QWKSNKE · 07-19-2008, 04:31 PM

no 24# will not be sufficient.

I also recommend no less than a 255 in tank pump. How much boost are you going to pulley it for?

95cobra · 07-19-2008, 04:33 PM

i will be using fpr. the setup is coming with 12# pulley so thats what im going to start with.

FYI 95cobra... QWKSNKE had a procharger on his last car, so his advice is from direct experience.

I concur with at least a 42# injector and 255 pump.
I sell 255 pumps: >CLICK HERE< I happen to have one in stock too.

Lee,did'nt you mention that you pulled an 11.5X with that setup? 95Cobra,I can get you a set fairly reasonable (including my "finders fee"),if you just let me know how soon you need them!

no my 11.5 pass was on a 150 shot many years ago.

Fastest I ever run was a 11.7@123 with a 1.7 60'. I never could get the car to hookup and leave correctly. This was on 15 psi of boost.

Man I miss having boost. Wish I could afford to put it on the new car
