what should i set the fuel pressure at? i searched and could not find the info i need so spare me the lecture. my set up is as follows a 190lph fuel pump, 70mm throttle body 73mm mass air , e-cam, pro products upper lower intake with 1" spacer, 1.7 roller rockers, so what do you guys think? any help would be greatly apreciated . maybe someone could make a graph or reference guide for future newbs like me cause i know this question comes up alot.

just set it at 42psi (stock) since without a wide band to monitor what your doing, a fpr isnt worth much. even with the wb o2, its not a smart idea to tune with fp anyways.

what about 38? i wont' get anything from it?

Black Snake

Finally got the rockers on ehh? Feel the difference on how easy it revs up?

Anyways, with the stock 19lbs I ran with 39 PSI.

I hear 37-40 PSI is good, It actually depends on the car and how it reacts.

ya felt a noticable difference. so can you run the car while you adjust it and hear how it's runnin? kinda like ghetto timing withouit a light?

Black Snake

Well you still need a light, what I did is just adjust it and test drove it till I was happy.

Took alot of trial and error. I got it right after about 6 tries.

philthy89fifty

you talking about the fuel pressure right? you have a gauge in the car right ? mine mounts on the fpr. i was kidding about the timing light. btw hows your supercharger install going?

Black Snake

Yea im talking about the Fuel pressure mines also in the reulator, so I braught a wrench and alen with me when I took if for a test drive and adjusted it to where I think it felt right.

Havnt got the SC yet, supose to be here Monday or tuesday, Im also still waiting on my Cal tube for my 42Lbs injectors from summit.

well hows car run now? put the gauge on first if its a rail mount. and see where your at before installing adjustable reg.
