Best Fuel Pump (130-160)

[md20]

Anyone have suggestions?

I would just get a Walbro that is a little bigger than you anticipate needing.

Good luck.

A walbro 190lph would be fine. I'd replace the fuel filter while i'm there.

A while back I did some calculations based upon numbers from a book called Four-Stroke Performance Tuning by A. Graham Bell.

_____________________N/A_______Boost
Ford EFI Options 80% of Max 80% of Max
110 _______________240______ 200

155 _______________340 ______280

190 _______________420 ______340

255 _______________560 ______460


What this means is that with a 20% margin of safety you can run a 155lph pump up to 340hp if N/A and up to 280hp with boost.

I have not compared these numbers to those from any other source yet so I would be interested in getting feed back if anyone disagrees. The problem is this author lists one constant for all cars/brands of pump/ etc.

Hope it can provide some guidance.

I would just get a 255 and be done with it. Dont have to worrie about it later when you start doing more mods.
