FPR Necessary?
Hey,
Just about done on all my installs but before putting it all back together wanted to double check on if I needed to put in a Fuel Pressure Regulator (FPR)?
List of mods:
Walbro 255
Greddy 720 sec.
Ported Wastgate
Apexi AVC-R (Going for around 10-12 psi)
New fuel filter
3" Turbo back Motoria Exhaust
Rtek 1.7 ECU
Removed Split Air Valve , ACV and Sub Zero Assist
Also if needed what has seemed to be the best one to go with?
I did search but didn't find what I needed.
Thanks,
Mike

That would work for me.
I am not going for agressive right now. Probably later on in the future but since this is my daily driver I am just looking for some extra power. Not looking to lay down great times at the track.

Hey,
I have a local guy selling this FPR for $30. Just curious if it is something worth getting at the price and adding it into my system?
sorry large pic but I didn't take it nor am I at a pc to resize it.
thanks,
Mike

Haven't we ALL heard this
For 10 bucks you can build a temp fuel pressure tester...
If your stock one is being overwhelmed you will note the fuel pressure rising above 40 psi i believe.

Hmm that's an interesting rule of thumb...

Am I wrong? When the FPR starts getting overwhelmed it won't hold the pressure...the pressure will just start rising?

wouldn't the pressure fall? if the FPR can't handle the pressure and become ocverwhelmed, the fuel should free flow resulting in lower pressure. Isn't that why aftermarket FPR are much larger? handle more pressure without failing?

If the FPR isn't big enough, fuel pressure will rise. It works very similar to a turbo wastegate. A wastegate bypasses exhaust around the turbine instead of through it. If it can't byass enough exhaust, turbine speed (and hence boost) goes up. An FPR bypasses fuel back to the tank instead of out the injectors. If it can't bypass enough fuel, pressure goes up and injector flow goes up.
