FPR: Rising Rate or fixed?

[alssupra]

I was wondering which FPR I should use with my 7M. I just purched a 255LPH Walbro fuel pump, I am running the Lexus AFM/550cc combo with a larger turbo. I'm not going for anything over 400hp...Yet!?

You need a rising one and here is the one you should get. It its a 1 to 1 rising rate. For every 1 PSI of boost you get 1 more PSI of Fuel. This is how the stock one works.

Here is a link to one of our vender's that carries them with new lines as well.

^^What he said. However, do NOT buy an adjustable rising rate regulator. I tried that once and you will not be able to turn it down enough for our cars. I had the go-go gadget smoke screen under WOT! The 1:1 is just fine.

that one is adjust able...as in fuel pressure. Or you talking about something else?

actually

the adjustable is just fine. The problem is specific to the aeromotive one. The by passs hole on the aluminum body is TINY. That needs to be drilled out.

I can't remember the brand that I had, I ordered it from Cartech.net. The lowest it would go theoretically was 2:1, but even that was too much fuel pressure on my 550's.
