Lethal Budget Return system @ 750whp e85?

[broke7]

I was planning on running this kit with my current 60lb Injectors until I made the choice to swap to E85 after being able to get E85 in bulk shipped via boat to Alaska.

Lethal Performance 99-04 4V Budget Return Style Fuel System [LP-9904BUDGETRETURN-4V] : Lethal Performance, Performance parts for Ford Mustangs

I am ditching my 60's, and going with 80's which I know they will support my power level (made 723whp SAE on C-16) so the 80's will suffice with a slightly elevated rail pressure on E85.

Just need to know if the twin 255's/gss342's will support 750whp worth of flow @ possibly 45-50psi of fuel pressure. I have heard 600whp safely being claimed on E85 with 60's with the injector being the limiting factor.

IF the 255's will not flow Im pretty sure the New Aeromotive Stealth 340lph pumps will......
Thanks!

YOUR GONNA HAVE TO UPGRADE PUMPS. On my gt500 I ran out of fuel on E85 with 80lb stock dual pumps an a bap at 5800rpm at 700hp

Thanks for the info. How was your injector duty cycle, and how much pressure were you running? I want to stick with 2 pumps if all possible due to simplicity and stock feed line capability. Fore does not have the capability of running the stock feed line with 3 pump 255/gss342 hat.

If you put a BAP on top of the 2 GSS342's it should be enough.

I would return the dual hat for the triple. Keep the other stuff and just get a -8 line to run to the factory rails.

I was running stock psi on stock returnless system stock fuel lines with a .25 Micron metal mesh fuel filter an a fore fuel rail for a return line for the E85 analyzer. You should be able run only 2 pumps they have return style pumps that run over 300lph now.

Thanks for the recomendations, for now I am just gonna do the following.


Triple pump Return Fore Hat
3 to 1 Y Block
-8 to Stock Rails (already have aeroquip pushlock running to stock rails)
80lb FRPP Injectors
-8 Return
Fore/Lethal Stock Rail F1 Fuel Pressure Regulator/Adapter


Car made 723whp on C-16 last year @ 27psi on a MMR Bottom end, and Stock Heads/Stock Cams, hopefully made a lil more on E85 at the same boost, maybe 750.

 

[04sleeper]

That should work perfect.

That's what I would have done if I switched over to a return system.

You should pick up some power for sure.

I'm running the exact same fuel system 100%. I had the dual version but the folks at Fore were top notch and swapped it out for the triple hat. I kept trying to talk myself into the dual pumps since I already had one but from talking to 04sleeper and a couple of others I went the same route as you. It is more work but I feel much better about the system.

What are the differences between this budget return kit @ 899.99, and the LP triple pump return kit @ 1999.99? And the dual pumps are enough to supply 700-800 on E85? (assuming I ditch the GSS342 for the Aeromotive 340lph pumps)

I know theres no rails included for the price and no 3rd fuel pump, but what else is missing that would constitute a price difference of $1100? This just seems to good to be true for me lol

 

[GodStang]

Looks great on the triple pumps. What pumps you use?

 

[alpha06]

I will be running Jay racing dual 340LPH Walbro Pumps. These pumps are suppose to outflow the Bosch 044 pumps up until around 95psi. These should be enough for anyone that wantless than 800rwhp, however, I'll know for sure ina few weeks.

Will the 340LPH Walbro Pumps fit on a Fore dual Ford GT pumps Hat?

Yes they will fit!

 

[VenomSVT03]

Yes they will fit!

How sure are you on this? Some people say they only fit the fore walbro hat, NOT the fore gt hat

I dont know about the Fore GT hat, but I do have these in the Fore 03 Cobra HAt.

Can somebody help answer the above? Want to go e85. Current set up is twin ford gt fuel pumps, 60 lbs, stage II fpdm, kenne bell frps disc, pprv delete.

 

[Termilvr]

Fore innovations has a twin 405lph pump setup that will be plenty :thumbup:

The budget system uses 2 walbro gss342's standard and feeds through the stock filter, lines and rails. It also uses a 2 port regulator and aftermarket return line.

The other system you mentioned which we don't even offer anymore used 3 gss342 pumps, aftermarket lines/ filter/ fittings and rails. It also uses a 4 port regulator and a triple relay harness. This system was replaced by our 1200rwhp system that uses 2 walbro 405lph pumps.

Let me know if you have any other questions.

Thanks,
Jared

We've had the DivisionX hats which are compatible with those pumps in stock for a while now. You can save by ordering the pumps and hat at the same time. Don't forget about the SVTPerformance discount as well!
