Ive searched and really cant find anything that relates to my situation. But im running a stock turbo, Aeromotive 340 fuelpump, 1200cc injectors ,E-85, and the car is tuned for 22psi and also has a dual map for 91. Other than that the car is stock. My question is to run my HKS 272's do i need more fuel ? If so what size injectors? Do i need another fuel pump I.E ( Double Pumper ) or can i run a inline pump? My HP goes is to break 400 on E-85.

Thanks guys !

That is plenty of fuel for stock turbo no matter what cams you'll use.

hks 272s are not that great of cams. Rather spend couple hundred more and get a set of S2's.

Ive done my research and from what ive seen they arent that bad. Ive seen all kinds of cams. My favorite are the Kelfords but I got these cams for a steal. Im not trying to make big power right now so for now i think they should do. especally on stock valves and springs.

HKS 272's are good cams, just older design and not real aggressive. I made 510whp on them, and they revved out nice, but I had to run them pretty retarded to get the top end. From what I read, the best way to get power from them is to get adj gears and go for -4 intake and -1 exhaust cam timing. Either way, they did well for the $200 I paid for them. I have kelford 272s now and the power difference isn't really that much.

Yeah. Those 272 cams are not for squeezing all of top end power like new ones out. But I don't think there are any others that could make more TQ under 4K RPM. They spool the turbo very fast!
I just got a set of S2 but still reluctant to switch out my HKS cams...

Thanks for the advice on the cam gears going to for sure look into that. And I totally agree with you they arent that bad as some people say they are. eventually i want to get kelford but I got these for 200$ too FTW

Yeah i heard that they dont take any bottom end loss out whitch is what im looking for. Ive heard great things about the S2, kelfords, and HKS. I got the HKS for super cheap so i said why not.

op may i ask you why you were tuned for 22 psi on E85?

DomsDDE85RS

I honestly could not tell you the answer to that. I got the car already tuned
