i want to know what is the stock fuel pressure psi, so i know what to bump my fuel pressure,,,its at 45 psi right now, but don't know where to leave it at, i tried it at 38 psi and lags alooot, i left it to 45 where it is right now, and it still lags...what do you guys think i should do?

 

so why would you need to bump the psi for?

 

ok so i lowered the psi at 40, when the vacuum line is off it reads 40, when its on it reads 30 is this good?

 

with a fuel pressure regulator how would 50psi run with basic bolt ons? isnt that like dumping fuel?

 

you need to dyno your car to find out the fuel pressure you should be using. leave fuel pressure where it is despite having the ability to change it until you know you should

Ummm, get a real fuel management system and some dyno time.

 

my friend installed an intake manifold on my car last night, and he bumped the fuel, i believe at 50 psi with the vacuum hose off, and when on, it reads 40 psi...i told him it might be too much but said that, that's where it's supposed to be at,

omg it was hectic today, we installed the manifold last night fuel was at 45 psi,(b&m BTW) after reading hear on HT they told me it was too high, so this morning i lowered it to around 40 psi,(with the vacuum off) which was lagging alot, so i was cruising down the highway today and came to a stop, then suddenly my radiator just shot out like crazy, all the water just came out, it was like a geyser, so i took it to my friend and he told me that the motor was forcing itself because the fuel pressure was too low, so that's was caused my radiator to go out, so luckily my friend has a eg with a b16 that is totaled and we took his radiator just so i can go home...the fan switch didn't go on so we wired it directly to the battery....

how is this for a Thursday night?????!!!!!!!!!

so as of now, the fuel is at around 48-50 psi with the vacuum off and 38-40 with the vacuum on

EDIT: my set-up is this....

CTR pistons
dc 4-2-1 header
apex 2.25 cat-back
straight pipe
blox intake manifold
cold-air
b&m fpr
f&S stage 2 clutch
itr flywheel

so psi too much?
how much should my psi be at with this setup?

 

oh and i know you guys are going to tell me to go tune it, but dont i need an obd1 and chipped with hondata or crome or anything that they can tune it with? i mean, i cant go and tune the damn thing with the stock ecu

Yeah, you do.
