Adequate fuel system for 600whp?
 

Wanted to get your guys opinion on what I was thinking :scratch: . Goal is 600whp stock long block on E85. Ill start by saying some idiot/previous owner cut the rubber fuel feed line between my stock feed line and fuel rail. It was then rigged backed together with some worm clamps lol? :censored: :banghead: I dont trust it. It needs to be replaced which is why im considering using the Full Blown Motorsports stock fuel line -6 fitting then just running -6 line there after and thenback to the stock hard return line. Also up in the air on a fuel pump. From what i gather I feel the 340 may fall short. All input is greatly appreciated. Thanks in advanced guys :tipwink:

Fuel: E85
ID2000's
-6an fuel line
Full Blown -6 for stock feed line
Full Blown fuel rail
Full Blown fuel pressure regulator
Full Blown 340 fuel pump?
Walbro 400 E85 fuel pump?

I was told the walbro 416 and new ID1300 would get me there and I would give up some power going with the id2000 to make it idle n drive normal. In for advice also :)

E85

Id 2000s

walbro 416

Stock fuel lines

Fuel pressure regulator of your choice

Good to go :drive:

618 whp here on e85 with FID 2000's and a full blown 340. Everything else stock.

Wow you squeezed a lot out of that pump. All I could get out of a 340 was 580hp.

x2

I ditched the 2000cc. Maybe I have a defective 2000cc set. It makes good power, but it would just not idle and drive oem like.

I'm running th ID1300 and it is a night and day difference in idle, cruise and partial acceleration and deceleration. Noticeable drop in cabin drone with the ID1300.

Plan is to increase fuel rail pressure so that the ID1300 can flow for 600whp. Just need to get a set of pumps to flow enough at high fuel rail pressures. Don't think I'll go back to the 2000cc injectors and would rather stay under 500whp if need be for daily driving.

^ that's what my tuner told me. Said run the 1300 vs the 2000 for around 600whp goal. I don't plan on using a fuel pressure regulator tho. Just OEM....hope its enough

I have FIC2000's in my evo and the duty cycle at idle is 0% lol. And I'm still not even close to fully using them at Wot. I think a smaller injector would be ok

Some good input! Hmmm. Maybe I should just replace that rubber feed line and keep things simplistic.

AEM Fuel pressure regulator on the stock rail? Then tap the rail for a fuel pressure gauge? :D :ponder:

I made 640whp+ on a FB340 with KB BAP and ID2000s. They def don't idle anywhere near as nicely as the 1000s or my original ID1300 which were defective as they swelled and reduced flow.

I don't get why everyone complains about the idle of 2000s. Yes it lopes a bit at idle. but I can hardly tell the difference once the car is moving. My car is run on the street only an I have zero problems. (662hp) Just wondering why people are so against them. :stick:

yea, i'm on FID 2000's and they idle perfect to me. i cant speak for any other brand but i would for sure reccommend FID 2000's for 600+ hp

My car idled great on ID2000s? Took about 30 mins tuning it in, but once it was done it was perfect.
Like stated 2000s, walbro 400, adj fpr, possibly a fuel rail, call it a day. I love my ID2000s, never have to buy another injector ever again.

I made 650 with a 255 and ID1000s :)

OG right here. 650 is very impressive with that setup...seems like you would have to be at the absolute max capacity of that fuel setup to hit those numbers..can be done but probably not efficient

ive been contemplating the same setup except wanting mid 700s. Guys hitting those high hp numbers on 1000s have gotta be running on lean afrs.

from what ive seen, the walbro 525 is just a 450 running at higher amperage...question is, how long will the 450 pump last at that higher amperage. There is a 17v and 21v version of the BAP
