Mark,

depends on your hp level. We ran an A1000 Aeromotive on the Procharged 406 at 700 rwhp and it was fine. I am not sure how far beyond that it will handle though; I had the same on the yellow car and at 800+ rwhp it wasn't cutting it. They make an A1200 which I swapped onto the Yellow Procharged Camaro and it was fine at 900 rwhp.

Dual 255 lph pumps are becoming very popular on blown motors. One runs all the time with the second kicking on under boost. I run twin Bosch pumps on the Chevelle and the Mule has the same basic setup, works great.

Jody, this may help Mark as well as myself...I was thinking of 2, 255 LPH pumps.

1) How much Blown HP will they support?

2) How did you set the pumps up?
In-line or 2 seperate feeds, as you said you had 1 going, and the other working when boost kicked in.

Would you be so kind as to post, or send me a pic of your system? If it's a secret or something, I will understand.

I know the Cobra and Lightning guys have been using twin 255's for years, at 800 rwhp or so. Not sure what the limit is.

The Bosch pumps I have are from Kinsler and are off the turbo Porsches from what I've been told. A separate inlet for each would work well, but mine are a single larger inlet, with a "Y" into the two pumps, and a "Y" back to the main fuel line up to the engine. The initial pump runs off the computer and the second works off a relay and hobbs switch where once boost is made the second pump kicks on. There is no pressure flucuation but additional flow is now available when you really need it (under boost).

Thanks for the info Jody...

One more question if you would.
I have the Aeromotve 16302 fuel pump controller, would you use this on the BOSCH primary pump to quiet it down and make it last longer?
Thanks for your help! Dave.

I also have that controller but am not using it with the dual Bosch pumps. The pumps aren't loud at all and were oem to be run all the time. I bought it to use with my Aeromotive pump.

If you decide to use it make sure that particular pump can run with lowered voltage. Some are damaged doing that from what I've read. There is a cool controller from DC Controls that pulses the voltage instead of reducing it that solves that issue.

Jody, If I remember, your pumps are on the frame, is that correct? That is not in the tank? So I guess I wont use the controller if they are continuous duty.

As Always, Thanks. Dave.
