Just trying to find out what are the highest HP double pumper setups out there and what type of modifications did you do to your setup to make it efficient as possible. If you don't mind, just list your setups i.e. single line/dual line, stock rail/aftermarket rail, stock 255/modded 255 etc. This is mainly specific to the buschur setup on E85, but other dual 255 setups are welcome also (but must be on E85 or better ethanol).

I guess you can just copy and paste this:

Brand:
Single/dual line:
Stock/modded pumps:
Stock/aftermarket rail:
Stock/aftermarket regulator:
Injectors:
HP and what type of dyno:
Notes: (any extra info such as inj. duty cycles and such)

Thanks in advance,
William

 

Lev, we did 850 safely with br double pumper. Modded walbros, each pump had it's own line, y'd at the rail. Id2000 and fpr at 60 base. We pushed it to 900 same setup, but idc's were too high. At 850 idc's were good.

 

Thanks bro. Does the mod to walbros affect the longevity of the of fuel pump (as in how long they will last before they need replacing)? I guess I'll do a little searching and figure out how to do this mod.

 

What do you mean by modded walbros? And how did you run a line for each walbro.? Thanks

 

Here is the double pumper for my Evo X. Kind of curious what they mean by modded too. They are two Gss350g3 which say they arent E85 compatible on Walboros site. Found this thread trying to figure out if BR does anything to the internals to make them E85 compatible or if I need to upgrade to AEM 340s which support E85. I guess I never asked if the hanger was for E85 when I purchased mine so no hard feelings.

 

It is recommended to use, and the part numbers are 267 .. 264 respectively...Using a pump may make your work smoother and better. . As technology advances, dual pumps are not necessarily required.

 

Bulletproof racing double pumper with dual 535s with a -10 feed and -8 return. Plenty of fuel to get you to the edge of the solar system. But I will play the game.

Brand: Bulletproof Racing
Line: Single line -10 feed, -8 return
Rail: Magnus
Regulator: Magnus
Injectors: Id 2600s
HP and dyno: Looking to do close to 1200 wheel on a dynapak, 1050ish wheel maybe more Dynojet, 900ish wheel Mustang
Info: Buy it and control it with an ecu not a Hobbs switch will make your life so much easier.

Wow I just posted on a 12 year old post Doh!

 

Brand: BR Double Pumper
Single/dual line: Single line
Stock/modded pumps: Stock 450's
Stock/aftermarket rail: AMS Rail
Stock/aftermarket regulator: Aero FPR, 43.5psi
Injectors: FIC 2150
HP and what type of dyno: 750/620 tq @ 38psi, dynojet
Notes: We ran out of fuel at 800hp/660tq on E75. Dialed back to 38psi, injdc is 77%ish
Will upgrade stock feed/return lines and rewire pumps.
