RRFPR or Standalone

[bimmerdreamer]

Im getting anxious to get my car boosting. The dilemma is whether to go full standalone or just run a rising rate fuel pressure regulator.

It would be great to go standalone- BUT its really expensive, is much more intensive, and will require a laptop for tuning and monitoring. I could do it but I would have to wait at least a year.

RRFPR- quick fix, cheap, and should support the levels of boost im looking for at this time (8-12psi). BUT- doesnt have the tunability of standalone, or the monitoring/datalogging capability, or the cool factor. If I was to go standalone I could do the project this summer.

so take the quick fix and get the car boosting or wait and go standalone?

BTW- if anyone knows of a good source for either hit me up!

If you compromise you'll kick yourself until you finally end up going standalone...

the RRFPR doesnt work on boost, decision made for you

Standalone.

Why would a rising rate fuel pressure regulator not work on boost? TCD uses them on their installs... the signal comes upstream of the turbo if I am not mistaken.

im not sure i read that somewhere, its probly cause they run under vacuum

RRFPR work, but they never run anywhere as good as those cars with standalones. Wait and do it right. I started with a RRFPR and ended up getting a Standalone..
