Walbro 465 pump.. max hp on pump

[98 N/A 4V]

I have 2 of these pumps but was wondering if anyone has any real world results running just one. I'm curious how much 1 will support on pump gas (No E85).

Novi 2k
93 octane
Base pressure 40psi
60lb inj

Thanks.

708 through an auto on a single? Holy shyt! I'm going to stick to pump or at worst 110 with will be maybe once in a while. Cool. Good to know.

Thanks.

I believe he is referring to Ed's setup in which case he is also running a bap.

Around 600rwhp is possible no bap depending on setup and boost level. Turbo always get further on fuel as they make more power per boost.

Ah ok. BAP helps a bunch. I think I might just put both in for safe measure. I'll just have to change my return line to -6 to keep the pressure down. But one should make 600. My motor is fairly efficient.
