I dont really see a problem with running dual walbros. Thats what im using in my setup (havent ran it yet though). If someone can give me a good reason why it wont work i'd like to know. looking at 20-25psi.... so far the numbers add up for it to work.

Well as a comparison, I remember a black FD3s with twin walboro fuel pumps beating a 20B TII with a TEC III and a T-76 https://www.nopistons.com/forums/pub...R#>/tongue.png

The Walbro pumps don't have the reputation for reliability that the Bosch pumps have. I got a Walbro pump a few years ago, and it went bad after about a month, and I ALWAYS had to crank the car twice to start it.

Isn't there two different style walbro pumps? A high pressure and a "regular" one? I think IGY is speaking of the HP ones.

Did you wire it with the stock wiring? The walbro pumps don't like the 6volts that the sock wiring puts out at idle.

IGY,

Incase you didn't know, APEXI BNR33 GTR fuel pump is the Highest flowing intake fuel pump out. There are numerous sites that say this. Here is a link to Maxcoopers site http://maxcooper.com/rx7/parts_info/fuel/p...pexi_bnr32.html



and another link

I don't know how much power you're making using the tiny Walbro fuel pumps, but they're not highly regarded here in the U.S. by ANY of the top runners.

I guess you forgot to put the APEXi in your first question, so I assumed stock. 310lph is pretty impressive.

Hey Jim, don't tell the supra guys, virtually all the big hp(700-900rwhp) are running dual walbros, but they're probably just guessing. https://www.nopistons.com/forums/pub...DIR#>/wink.png I suppose 9 second 1/4 miles don't count as "top runners, LOL. Missin ya Jimmy

BTW, I was going to use your Stealth club link to show you that you're mistaken, but you've already done that for me.

Guys,

I'm not trying to start an argument here. I respect everyone here especially people like IGY, who has a BAD ASS FD! I just think its really confusing when you have reputable people stating different opinions as fact. Soooo, if anyone was offended by my post, I appologize. And I would like to see Dyno sheets from Carls AWESOME and RARE SUPRA, pls. https://www.nopistons.com/forums/pub...IR#>/bigok.gif I think you're one lucky dude Carl.

I would like to know a couple of things, if WALBRO is so great and affordable, why would anyone use anyother fuel pump? Maybe PORCHE and many other SUPER CAR manufacturers should save some money and use WALBRO as OEM pumps.
