Default Which fuel pump for 650-675hp

I project my new engine will be 650-675ish to the flywheel. It currently has a Racetronix pump in the oem bucket and Racetronix wiring and it's not rated that high. What would be some options? I didn't think dual pumps were necessary but I don't know much about fuel systems......Thanks guys

The Racetronix hotwire kit with a Walbro 255l pump? If so that should hold 650 fwhp

Not really sure which pump, it's red anodized but I didn't see a part number......Racetronix lists 2 pumps and the larger one claims to be good for 600hp

What has to be done to put the 340lph in place of the 255lph?

You have to cut the bucket up some.
No big deal. It's the same physical size. It gets it's fuel from outside of the bucket.

Will this have any negative effects launching at the track? I was under the impression that the bucket helped keep a supply of fuel for the pump

Just keep atleast 5 gallons of gas in the tank.
Don't listen to a bunch of people that have not done this mod and read a bunch of internet BS.
I have this pump and no problems.
Still using stock fuel line and no return line and stock fuel regulator in the bucket.
