ok i have a LS i/h/e will boosting the fuel pressure do me any good in the HP department, ie a quicker 1/4 mile run

if so what it stock and what should i go up to

i really dont think so...

stock should be around 40psi with vacuum hose removed.

 

i did some research and stock should be between 40 and 49, but upping it i dont know what that will do wiht what i have....probably nothing but i juts got a B&M for free so hell why not put it on

 

whoah whoah!

no no!

unless you can measue your fuel pressure, dont put the B&M one on!!!!!!!!!!!!!

if you got it free, buy the B&M gauge and do it properly!

you wont be able to set FP at ALL!

thats why not.

It might help a little bit. But if i/h/e is all you dod, it probably won't help much. And listen to what the other guy said. DON'T use an adjustable FPR without some way of knowing exactly what the fuel pressure is. In fact, the proper way to start off using an adjustable FPR is to first measure the stock fuel pressure to know where to begin. Then add the adjustable fuel pressure regulator and start at stock pressure. The B&M gauge is inexpensive and easy to add.

 

ok yeah definatly, my dad has a gague bot filter mounted thouhg, but i will probably get the gauge, they run like 35 bucks i think

but the question is, if bumping it up will help even a little, what to i bump it up to above 49 btu what does anybody elese run

i have a K&N filter and a close to stock exhaust (cat-back)

i run 42psi, which is close to stock.

turning it up doesnt help uintill you have more *airflow* through the engine...

with i/h/e maybe 44 to 46psi in a B16A is cool...

(sorry i dont know your engine etc...)

t..

 

are these fuel pressure numbers with the vacuum hose attached?

 

of course.

how else do you measure it?

 

i have a LS b18b

 

thanks bro. i was asking because when u take off the vacuum hose of the FPR the FPgauge reads a higher pressure than the reading with the hose attached. now i know u based the numbers when the hose is attached. thanks
