And you thought a Supra pump would overrun the stock FPR....

[RealMcCoy]

5x stock resistor packs tied together?

We'll find out shortly, it's almost done, but it was pulling 15 amps as the above pic was taken... I'm theorizing that the same doubled up resistor I use on the supra pump will do the trick.

Still has a slight overrun... Averaging around 41 psi at idle. I'm probably going to leave it there. I should be able to tune around that quite easily.

Is it the Wally 400, or the aero 340 that does not like anything but full voltage? I read somewhere it was not good to run one at a lower voltage, unsure which now.

I can't comment on the Wally, but the Aero 340 is specifically advertized to be suitable for PWM applications.

Ok, I will take a look at my info when I get a chance. It must be the wally instructions I was thinking of.

Good work!

I run a hotwired 340lph pump with a Fuelab 515 FPR and a gauge. After leaving the car for 2 weeks it started within seconds. Obviously the leakdown isn't that bad on it.

My fuel pressure leaks down on twin walbros with Sytec fpr when stood, but it will fire up within 2 seconds after being left a week or more..

I've run a single Walbro 255, Denso Supra, twin Walbro 255s, Aeromotive Stealth 340, and now a Walbro 416 E85 fuel pump on the stock fpr. You can definitely tune it out. Anyone that says otherwise hasn't bothered testing it. I've even pegged the wideband lean at idle before experimenting because I thought overrun would be an issue. I still recommend an AFPR for better control but sometimes it's nice to keep things simple and closer to stock.

I've got my ARC2 pegged right now trying to compensate for the extra psi at idle, if only I had one more click
