I think it would either be an F90000267 or F90000274

What bigger pump setup did you go to?
What was your apparent HP limit with these pumps? On E, or pump, or pump and meth?
I have dual 340L pumps and I’m certain my new build will outrun them.

These were in a friends 5 second (1/8th) turbo LS 3rd gen Camaro. He upgraded to single magnafuel pump. These would typically be used with a Fore fuel pump setup in our cars. I'm personally running 2x340's and a dsx aux pump. You well be will over the capability of 340's. A local has a 427/2650 and he tried larger aux pumps and other stuff but never could keep from running out of pump. Eventually he just put a Fore system and ID1700's in.
