How many of you guy's run one. I was thinking of doing this because it's cheaper the getting a double pumper. What do you think.

You mean an inline pump or a Boost-A-Pump? If you're on E85 then an inline Bosch 044 will get you a long way.

How's your car running anyways? Just run a boost-a-pump on a single walbro in tank. Jake (311evo) hit 530whp at DB with this setup with room to spare.

I had to put in all new bearing and a new 100mm crankshaft and now I just waiting on getting a clutch. Iam running a single walbro in tank thats why I was asking about the booster pump. Shane at DB side I would run out of fuel at about 450 to 470 with 1000cc injector and I want to be close to 550 to 600 and that I need a inline pump with mt in tank walbro or double pumper.

Well, I would run a modded single pump (shane can show you this) with a BAP, hands down. It worked on many other cars and it will work on yours. That should get you to 550whp at least and if you make more than that then worry about the dual pump setup or an inline or something. If you are 130% sure it will hit 600whp on shane's dyno then you might need more.
Wait, are we talking about 1.0CF or shootout numbers? What turbo are you running? Your 470whp sounds like shootout numbers....if that is the case then just go for the single as stated.

A Boost-A-Pump is not an inline booster. It's a voltage booster/regulator. Some guys run that, some guys put a Walbro GSL392 inline or a Bosch 044 inline. Some guys run a Walbro intake plus a Bosch 044 or GSL392 outside of the tank, but with a pickup intank in parallel.

You will need bigger injectors. With 1 intank Walbro with stock wiring to the fuel pump on E85 you would probably max them around 420awhp on my dyno. With good fuel pressure with 2 pumps or whatever they might be able to handle another 10-30awhp.

Like was said, there's a few options. BAP will just increase voltage to the single pump, causing it to flow more. Adding an inline external pump (dual pump in series) is another way t get more fuel to the injectors. Not sure about evo's, but twin intank pumps in parrallel is another option possibly. Pick your poison :)
