Im buying a super charger and some 8.1 marine injectors come with it will these injectors fit in my truck its flexfuel and will they be enough?

 

What supercharger kit are you getting? 8.1 marine injectors should plug right in.

 

not if its flex fuel the connectors are different .but all you will have to do is find someone that sales the adaptors .

 

kenne bell

 

ok so I will have to get adapters, anyone know it they will flow enough with the super charger and cam.

 

i think the flexfuel injectors are 42lbs...might not need the 8.1 injectors

 

8.1 marines will be plenty enough

 

i have flex fuel if you are running 5 to 6 psi stock injectors will be ok tune truck and check duty cycle with stock injectors.

 

Il try it, im gona have the same kenne bell as you so il take ur word for it. Are you running 5 to 6 with the stock pully? What do you guys think of the cam i have with the sc its a 220/224 530/534 112lsa with the 1.75 rockers the lift is in the 540s how do you figure the overlap?

 

I'm running 6.6 lbs boost on my Radix and using my flex fuel injectors and stock fuel pump with no problem. Magnuson sells their flex fuel kit without injectors or fuel pump as they are both higher capacity for flex fuel application. I believe the FF injectors are 38 lb. rated. Magnuson customer service is first rate and you could call and ask them how much boost a FF engine (injectors and fuel pump) will handle. Also FF engines run at lower fuel press. than stock engines. 48~54 lbs with key turned on with a drop of 4~10 PSI at idle is acceptable according to my GM service manual. They list 55~62 PSI for a stock engine fuel system with key in ignition and turned on. For comparison, My truck is 50 psi with key turned on and 48 psi at idle.
