Added Boost - What Fuel Pressure?

Will be installing Jim's MVM stepper pulley next week w/ RC310's. What fuel pressure should I be at (idle/static)? See mods in sig.

Any replies will be appreciated [img]graemlins/thumbs_up.gif[/img]

36 psi static. Your rise rate should be about 3:1.

I will drill a 1/32" on the stock fpr to lower the static to ~36psi.

I know that the JR is a 5:1 rise rate from factory but how do I know what the rise rate for the Cartech 2025 is? How can I adjust the Cartech to get the 3:1 rise rate? I'm confused.

You should have a fuel pressure gauge and a boost gauge. Measure your max fuel pressure and you max boost. Then compare this to static. Subtract the difference in FP then divide by your max psi. That will tell you what rise you you have. As for adjusting the Cartech, search the forums, it's been covered a million times, or check their website for the instruction manual.

Thanks for the clarification on the rise rate calculation. It makes sense now. That was my only question. The Cartech adjustments is simple [img]graemlins/thumbs_up.gif[/img]
