I have a Buschur double pumper. I maxed out at 750 with pressure dropping, was wondering if anyone is running dual 450 e85 pumps. And if so how much power have you made on them. I'd rather run intank then a big external pump if possible.

 

Yes its been done with in tank 450's. My buddies in the high 900's

 

at those levels you can maximize your double pumpers if you have upgraded feed and return lines. I would start with those before upgrading the pumps.

 

Ok cool I was a -8 AN and will be installing -10an now. The Buschur double pumper with the 255 is only good for a little over 700whp. I have a walden external pump now and just pice up a 450 but thought the dual 450s would be better. I know they draw alot of amps and I need to upgrade wires and fuses but that's easy to do.

 

Putting together a dual 450 setup now. Shooting for 750 but I know it will support over 1000 if I ever get that crazy

 

That setup is Killer !
