Ok that makes sense, because 10.7 @ 128 is around 500 whp on a Dynojet for me and 600 crank HP and about what I calculated as being max safe flow on the single Walbro. I don't think I can hit that without race gas or E85 on my current turbo plus 30-35 psi boost and cams but having some safety margin would be nice.

I can see where this combo could allow 550-600 whp (660-720 crank HP?), what if both were Walbro pumps or has that combo not been tested yet?

The external pump is not very loud at all with the foam cover.

forgive my ignorance - but would this also help on the track to avoid fuel starvation? If so yes - very interested.

That would definitely raise the flow rate a little but the best route to go would be to run twin inline pumps mounted externally fed by the stock pump. That setup would flow about 500 lph at 60 psi and would be able cover you for almost anything you can throw at it.

That depends on the design of the stock tank because the factory pump location is still being used.

They did this setup on Ryan Gates car and I saw it, it looked pretty sweet.

I am guessing his is a little more custom, but he was still using the DW1000cc injectors (im guessing with raised fuel pressure) running 520 or so whp.

So that would be an awesome setup.

*Update* I am finishing instructions and a few other things and we will get them up on our site shortly there after. The price for the kit will be $399.95.

Does this kit come with a new fuel filter? And all this stuff is E-85 rated or at least you guys use them in E-85 cars right? I know a lot of stuff isn't rated but a lot of people don't have problems with them.

Ok good info! Since I'm lazy and don't want to buy another stock pump I would just assume leave the Walbro pump I already have inside the tank and add on from there. Maybe I could test an Aeromotive 800-1000 HP rated pump for an E85 setup instead of going Twin Walbros. My concern is with a twin setup that running with one pump dead would be hard to detect until you are at WOT and running high boost where you are exceeding the cabability of one pump without knowing it, I would rather just have it stall the car or be more obvious that a pump is down.
