What type of injectors would be best and with just one pump. Heard people go with two pumps. Would that pump give me any issues or should be fine

 

so your telling me with just 1000CC injectors and 250 map and tune would be enough to go into E85?

 

what brand for injectors is it good and after adding a down pipe is it really neccesary to do another tune?

 

FIC1100. Great injector for anything from stock on pump gas to 600 whp on pump or 480 whp on E85.

 

I need help!! Dores anyone in the Bay Area(California) know a good place to get my car tune in a dyno shop? Any sujections where i can go where i can trust them with my car??
: mitsu:

 

For that level, I would recommend one of the new HP E85 Walbro 450's. Safe up to 700 WHP. A 255 will do it but the 450 will give you room to grow.

Give me a call if you want one. 585-226-8226

I am running an inline Fuelab 40421 Prodigy pump (-10 feed / -6 return) and it seems to be fine. Only at 400awhp right now but plan to go to 700+

 

Is there any particular reason there hasn't been mention of a dual pump setup like Buschur's Double Pumper?

 

Because a double pumper isn't needed for less than 500whp on a Dynojet

 

True. I guess I forgot the original question was about up to 500 whp. When I needed to upgrade my 255 I went double pumper just to know I have enough for future modifications. If I knew I would never push my setup much further I guess it would be overkill.

 

Hell, with the walbro 450 and proper fuel system upgrades, 600whp dyno jet isn't out of the question.

 

I could see that. My 255 didn't fade bad until around 450 whp and 600 whp is only a little over 30% over that. Walbro 450 about technically flow around 30% more than than the 255 also.

 

At 90psi of fuel pressure, the 45o flows more than what the 255 is rated for at 0psi.

The new E85 Walbro 450, wired with an STM Fuel pump rewire kit should make 700WHP.

Walbro claims its safe up to 800HP on E85. We have not tested one that high to confirm.

Here are some stats on the new 450

Walbro 450 LPH High Pressure Fuel Pump (E85).

- Universal In-tank Fuel Pump

Fuel: FLEX (E85 Safe)
Horsepower: 750HP+
Flow Rate: 450LPH
Part Number: F90000267

- Outperforms all current market in-tank fuel pumps
- Designed for engines with more than 750 HP
- Award-winning OE technology
- High-pressure, high-flow performance OEM technology designed and developed for E85

Dual channel turbine design for maximum efficiency under high pressure and high temperature applications Made in USA by TI Automotive (parent company of Walbro.)

All pumping components have been validated to OEM specifications for approved use in E85/flex fuel applications.

The F90000267 requires modifications to system wiring, fuel lines and the fuel module, and should be professionally installed.

The innovative design of the DCSS 39/50 features a single impeller with two parallel rows of turbine blades. Designed for high performance engines exceeding 500hp and safe for E85 or Gasoline applications.

The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that's 20% higher than conventional pumps.

SPECIFICATIONS:
465 lph @ 40 psi and 13.5V (14.1 amps) in gasoline
Outlet diameter: 10mm (3/8")
Diameter (upper body) 39mm
Diameter (lower body) 50mm

That's awesome. Well under half the price of a double pumper also.
