Overkill for 550hp yes, but leaves plenty of room for upgrades.

very nice good luck :

looks promising...

I see it needs a return line..so no dead heading..

its not a submersible, so thats good to where the fuel cell doesnt have to be changed out if you went to Injection..

looks like a very nice pump...

so who is running one now..

-8 in and out was kind of a tell. It isn't a monster , but should deliver pretty good volume.
The h.p. estimates that it will support might be on the generous side , and I don't know if it is designed to draw ( I am thinking yes ) or if it should be behind the tank.

I am glad you posted this question. I was going to ask the same thing. I am using an old BG280 with a stepdown box for the street. I want to get a new pump. This one looked pretty nice.
