Hi guys

I'm aiming for 350bhp from by b16.

Will the stock FPR and fuel rail be ok at this power?

 

id imagine it might be the upper end of what it could support, my R made 350 whp with the stock fuel rail and regulator.

 

Yes - I made ~400whp on E85 (requires 30% more fuel than gasoline) with stock FPR and rail, you'll be fine... I wouldnt bother upgrading until you're in the 500whp range IMO

 

i have 369 on stock intake ,just different injectors...

 

I would at least upgrade the FPR to something like an Aeromotive. The stock fuel rail is fine.

 

Same answers to these questions as in your other thread.

Fuel pressure regulator means nothing unless you need to adjust your fuel pressure for whatever reason. I thought it has been long accepted on here that the stock fuel system (aside from fuel pump and injectors) is good to 600hp. Unless something has changed all of the sudden? Heh, there were even very argumentative threads on this subject matter.

 

I'm such an idiot.
I'm a member of so many forums that I sometimes post similar questions twice.

 

Sometimes I see some problems with stock FPR's that they can not a stable pressure at half throttle with, for example, a Walbro 255.
