Best fuel pump to run?
Hey guys, quick question, I'm wondering what would be the best fuel pump and injectors to run for my 06 evo. I'm trying to build it to run e85 but still running 91 at the same time considering it is still daily driven. For my setup hoping to reach around or alittle above 500 whp. I also don't plan on keeping the stock turbo, I will be upgrading soon to a ets turbo kit just haven't decided which to go with. I've heard the walbro 255 and 1000 cc injectors are decent but I'm not sure if that will get me to my 500 goal. Any advice at all is greatly appreciated! Thanks again guys!

1000cc will limit you to around 450ish on a single pump on factory wiring. The easiest way to get there as far a fuel setup would be 1200cc injectors and a double pumper.

AEM 320 --- Reliable and flows a bunch.
I'm partial to the FIC 2150cc but they're pricey. |

The reason i asked because me just like op I assume want to know what's the limits. I made 365 on e85 mustang dyno. Don't know how to convert into dynojet but looks like we have some room.

If you intend on making this system E85 safe over the long haul, the Walbro 255 doesn't fit into your plans. There is another Walbro in-tank pump, the -267 or 416 lph pump, that is relatively easy to swap. The good news is this pump has the capability to deliver more than enough fuel for the job. The bad news is your skimpy factory wiring cannot deliver enough power to support the demands of the pump if its full capability is to be realized. That will materialize only if the factory wiring is fully upgraded with large power and ground leads. If this is accomplished, the pump will have the juice to pump enough E85 through your puny fuel feed line to get you 500whp. IF you have enough voltage at the pump to maintain at least 3 bar (44psi) at the fuel rail at full tilt, one may be able to squeeze 500whp out of 1000 lph injectors with sharp tuning if everything else is mechanically efficient. As previously mentioned, 1200s give more headroom. If you're going to do it, I suggest doing it right the first time. Avoid doing what some folks have done, having undersized/underperforming pumps and trying to band-aid the pressure loss at the rail with oversized injectors. Don't fall into that trap. |
Upgrade fuel system double or better and some 2000 you will be safe ;)
