Fuel Pressure?

[beeza]

Thanks Heaps Guys.Great Info!
Cheers Dave,that's what I am talking about.I initially got the idea from you when you put in your FPR.So that answers my query.It's simple then 10% increase in air flow in = 10% you can increase the Fuel Pressure.
Ha Ha,I know I had planned on getting a header (I will in the future),but I Love how my car runs now,stealth too,cause a Header will make it quite Grunty yeh?
The MSD System is the shit! I Love it!
MSD Box (Multiple Spark Box)
HVC (High Voltage Coil)
I Had to Modify the Stock Dizzy Cap with a MSD Power Tower since MSD don't make a Modified Dizzy Cap for the D16y4

im sure you've seen a fuel pressure regulator before haven't you?

[crx88rb]

walbro fuel pump + sard reg = 45 psi

but that formula for 10% increase is in relation to vacuum... pressure rises the higher the revs.....

A Nice Bump in Power For sure.Obviously nothing BIG but Definately worth doing.
I installed a Walbro 255LPH Fuel Pump 3 weeks after that.I know 190LPH would have been suffice but I thought what the hell it cant hurt.If I decide to do Major Mods in the future (when I get $$$-Ha Ha) it will be better to have the bigger pump.And offcoarse there was no increase in power but I reckon my 10 yr old pump wasn't cutting the mustard anymore.
I'll take some snaps of My engine bay tomorrow,I've been meaning too .

Depends on what other mods ya got but

i/h/e billet cams, cam gears, safc2...works nicely

Peek a Boo I can C U


Why Not

good you have a gauge on your setup... notice how when you rev the car the pressure goes up... it's rising rate... supposed to provide a little extra fuelling in higher revs....

it's controlled by that blue hose you have at the top.

[Mr_will]

fair to say that the rising rate regulator might make more of a difference if you have msd?

bit of a noob when it comes to fuel pressure stuff so willing to stand corrected

Nice thoughts , but point is with current mods and engine , increasing fuel pressure will not yield any results apart from leaving more black soot on his bumper.
