I have a walbro, just one, in the tank, making 400hp. stock primaries,1600 secondaries, aeromotive regulator. My car NEVER runs lean, starves for fuel, ect. I love the walbro pump, had it for over 2 years, works great, no complaints.

Oh and BTW, it's ******* obvious that manufacturers like porsche will use bosh pumps, everything in Germany is bosch. Walbro pumps do come stock in some american cars, and many a fast track car use them. So don't knock what you don't know. I'm not defending it becouse I have one, I'm defending it becouse I know about them

I'm not to sure on what a track inspector might say about running the setup you are talking about, and in all honesty if youplan on running dual Walbro's into a single bosch you might find you are acctually restricting it more than helping it, you will have to deal with the restrictions of the fuel lines, if you push the 500+ liters of fuel into something that can only push 300 then you create a restriction. Now I have seen twin Walbros running on Scotts blue car, and twin GT-R pumps (R32 stock) in Fergys R31 Skyline w/ RB26Swap and 720cc injectors. Both cars never really suffered from fuel starvation or fuel pump failure, although Igy may know something different on Scotts car, but I do know both of these cars are at far higher power levels than your looking to achieve and both do fine with twin intank pumps

Who are you (camel) refering to , me ? , If so my fuel lines is -8AN (5/8" I think) , and I want to tie in the discharge of the twins into the A 1000 discharge , not go through the pump.

Jim, I just pulled the manifold for porting(it's cast, I know, I know ). I would Imagine ~640+ on race gas, and ~525 on on 91. I really do not know, I had major boost creep initially, and had to pull the whole set-up. It was only in for a day, aargh........I had to switch from anMy Webpage Innovative wastegate to the 60mm HKS GT wastegate, in order to do this, I have to add material to the mounting flange, and then port match it to the new wastegate. Jim, where did you read about my Sup(just curious)? I just just put a bronze six puck in that car, that is one tough bitch to drive in stop and go commute, but it is fun to spin the tires on the 2-3, and the 3-4 shift. Anyway, I know you are mainly givin me a little **** cause I have no dynos

Anyway, if you are serious, thanks for the props.

On topic, I think that there are lots of choices out there, just depends on what is proven in the particular car. I suspect that the bosch pumps may oulast the walbros, but they do roughly the same job, and cost more than twice as much, the bosch pumps certainly won't last twice as long, so why spend the money? For certain there are Supras out there with 30,000 miles on the walbros, and I have not heard a complaint about longevity on Supraforums before. I have heard several complaints about the longevity of the Supra pump when run on 12+ volts. I think most everyone on here can come up with something that will work, but I think saving ~300.00 for pumps that do the same job is worthwhile. This is a forum, the different points of view are what make it so valuable, Jim's right about the performance of the apexi, but it is certainly not the only solution, anyway peace, and I will post dynos on the Supra as soon as I get them.

BTW, Jim, do you have a divided manifold that will allow me to fit a T66 on the FC?
