did alot of searching and all i can find is people running dual 255's or a 255 with a bosch 044 inline combo.. in the middle off a build and shooting for 600ish hp on E85 using 1600cc injectors.

Will the walbro 416 pump support this kind of HP? i really dont want to run a intake AND a inline.. like to keep things as simple as possible.
Thanks in advance

 

Its IN TANK, not intake.
And yes the big Walbro 416 is what you want.

 

Thank you Muckman, yes in tank, not intake LOL loooooong day. And im glad YOU responded, between you and a few others on here I know when yall answer, it is 100% accurate. will be ordering the 416. THANK YOU!

 

i've seen a car make 616whp with the walbro 450lph drop in pump and id2000's on stock lines and stock filter on e85, but injectors were pretty much maxxed out.

 

Prob was the stock lines then. Thats a lot of volume for stock lines.

 

glad i saw this thread, was looking for a better pump over the 255 without going the inline route...thanks!

 

you could also look into the Bosch pumps.

 

Care to elaborate on the Bosch pumps? I have a 92 integra I'm currently upgrading the fuel system on. On e85 with Precision 1200's and a Walbro 255 it made 357 on a Mustang Dyno maxing out the injectors. Stock lines and rail and a 1,000,000 mile old fuel filter.

 

What about the AEM pumps. I think I read a post that said they made high 500's on just 1 of them. True? So then, 2 and some better plumbing should take one way past 600whp, right?

 

If you run the 416 or 450 be sure to run at least 10 gauge wire and a 50 amp fuse. The contactor on the typical 30 amp will run hot and fail over time.

 

when you guys say need aftermarket fuel line, are you saying all the way from the pump to the regulator/rail or just run aftermarket from the line in the engine bay at fuel filter to regulator/rail?

 

I would also like to know more about bosch pumps.. ive looked online and all i can find is either inline or a 255 stayle in tank.. am i missing something? ALSO! were is everybody buying the bosch 1600cc injectors.. googled the crap out of it and looked at MANY aftermarket sites and havent found anything that big except ID's

 

You need to upgrade the fuel feed line from pump to filter to rail. The whole thing. Return is not required but youre right there...

 

ok. Thanks for the answer. What size is best? im sure with fluid flowing in the lines the correct size is important. Does the bigger line require more pressure? only reason i ask is because of experience in the past with brake lines, changing size would change the action of the brakes greatly

 

Hydraulic pressure is different than fuel pressure, much more psi in hydraulic systems than fuel systems. Besides that's what a good fuel pressure regulator is for.

With fuel line I start at -6 and move up the scale depending on power goals and fuel requirements. The question I'd like answered : Are banjo fittings suitable for a 450 whp -6AN application? I've never used them in the past, but I may have to on this 92 Integra.

 

does the factory size lin e on the fuel pump assembly effect anything? like the lin e the pump feeds and comes to the top of the sender assembly..

 

Would you also suggest this with the Walbro 400?

 

To be safe, yes. I have not witness the relay failure with a 400.

 

The Bosch 044 will also do it, it's a tried and true product, granted the price point is somewhat high but I myself have never heard of a unit failing.

 

Guys,

See bolded. Per TurboLS and D-rob(Bill)

 

hmm, I've been running mine for about a year now and the wiring is fine (10 or 12g) with a 30AMP fuse

 

A very good friend/shop owner had his 30 amp fuse fail. I originally thought 10 ga and 30 amp would be enough per the walbro spec. but it seems as if people are having some trouble with tha set-up.

 

We are putting over 600 on a AEM 320lph in tank pump and Bosch 1600's Injectors
