Maxing out stock feed and return.
I'm curious on what's the most power the stock feed (3/8) and return (5/16) will support?
I will be running 2000cc injectors. 1 Walbro 416 pump. Aeromotive regulator on e85 fuel.
Wanted a idea on what this fuel set up would max out at. Thanks.

According to the article, the strength of the fuel pump is the limiting factor up until a point.
1000+ hp on stock lines with the correct pump selection >shrug< just reading.
Change the lines to make it easier on the pump.

Re: Maxing out stock feed and return.
Does the Civic Del Sol have smaller fuel lines than an Integra? (I think it does) My friend ran into a wall around 450hp on E85 with stock lines on his Del Sol. Couldnt maintain fuel pressure with a Walbro 400lph, Ev14 1600cc. Replaced FPR, eventually upgraded lines and smooth sailing.

There's quite a few s2000's that are at the 700whp level on e85 with stock likes with a Waldron 400 and 2000cc injectors

62mm B series car went 791whp(Dynojet STD) on Ignite Red which is considered E90 before i saw it leaning out. This was on the walbro 416 in tank, bosch 044 inline and grams 2000's with the base pressure cranked way high.

Re: Maxing out stock feed and return.
I've tuned a friend of mine's car on stock lines using e85 ID2000 450lph and made 619whp. Pump couldn't keep up in the higher rpm range.

Dual aeromotive 340lph with individual relays & #10 wire

-6 return
Aeromotive A1000 regulator
same 1200cc injectors
looking to push 600+WHP
