i was just wondering if i boost 20psi and use 450cc injectors do i need to get a better fuel pump or will the 450cc be enough to keep it from running lean

20 PSI WHAT DO YOU THINK?

you not only need a bigger fuel pump but you also need fuel injectors bigger than 450's

you need to do some reading

i bet you think stock block can take 20 psi

ssdelsolsi

yup! ur block will love 20 psi


you cant be serious

You could run 20psi on a 14b probably. psi doesn't break motors, max hp does.

20psi on stock motor, No.

20psi on 450cc injectors, has been done, but it takes a better pump and more fuel pressure ( about 50-52psi) to do it,

guys, quit referring to psi as if it doesn't differ turbo to turbo :1

bumblezc

I know it differs from turbo to turbo.

Just answering a question.

im not a idiot i know my block wont hold 20psi i ordered devcon and m filling it but all i see is people saying they put 450cc in dont usual say anything else about the fuel system.

nonvtec

You'll probably need a fuel pump for safety, but you need to give us a hp number you're shooting for, psi means nothing.
