Raptor 150 or 100
hello i am deciding what to get becasue i am done doing mods to my truck now i just want to get a good lift pump. At max im pushing 430 horsepower. Will this help my problem also that i am having if i switch. Because lately my ddrp has benn pushing 20 to 24 psi of fuel pressure at idle. and it makes it sound like it has a little miss at idle. My question is if i get a raptor pump that i can adjust fuel pressure to about 17 at idle will this get rid of the miss im having because right now the only time i have a slight miss is when it is at 20 psi or 23 psi at idle.

Do you guys think if i can get my fuel pressure down would the miss go away.
|
I would get it down below 20psi you could damage the diaphragm in the vp pump.But yes getting it below 20 should get the miss to go away.Unless you have injectors that have different pop pressures.
|
is their any possible way to get my pressure down on the ddrp pump?
|
I would call fass and see what they say.That pump is not adjustable.:humm: That is to much psi at the vp44
|
maybe you can modify the overflow valve to open earlier.
|
FASS can send you a spring to change out in your DDRP.
|
i wander if it would cost any thing being that their pump messed up?
