Fuel Pressure

[jbower86]

I have a quick question for anyone who can answer it.I just completed my Mass air conversion and installed a 75mm throttle body and egr spacer 24lbs injectors fuel pressure regulator and cold air intake ,I was just wondering what the fuel pressure should be set at for now the car still has the stock 86 bottom end and a gt-40 intake that is ported fully.I know i am not getting the max preformance out of it since it still has the stock 86 heads and cam in but that will change soon just want to get a couple of pass before it goes to Ricksgt for a make over to a 331 low compression and a blower can anyone help Thanks

I feel a stock motor runs best around 32-33 psi. I would think with your combo, to try 39-40 psi vacuum off first, and then possibly work your way down, as the ECU will try to handle it after so long anyways.

i agree, you can try to over d the fuel and then work down, and see what works the best for ya. You will know more when you get that gauge working too.

guys: the reason some of that stuff is so big is that he bought it early for his 347 blower motor that Rick is gonna build for him.

i think that is one in the same (38-39 vac off usually equates to around 32-33 with the line connected at idle).

great choice having Rick do the work! i would love to have him do some work for me. i cant afford it, so i choose to simply bug him with emails.
