Hello, I'm about to receive my ms3pro sometime next week.. and I have some questions.
1) What supporting member here can give me a good deal on ID1000 and fuel pump to run e85?
Back in the day I bought an AA stage2 turbo system then I upgraded to the stage 2.5 which according to AA I needed to to upgrade my fuel lines which I bought from them. It was a slightly larger aluminum tubing plus other parts that were rubber hoses.
2) Can I used the aluminum section of the fuel lines and just upgrade the rubber sections with whatever hose is e85 compatible, or replace all fuels and with what size?
This will be installed on my e36 m3..
96 M3, GT4094R, Arrow Rods, CP Pistons, Elring HG, cutring 87mm, 10 mm ARP studs,MS3pro, EMC Intercooler, n54 6 speed with Motiv twin disk, ZT-2 wideband, Zionsville Radiator, X-brace, H&R springs with bilstien shocks, QTP electronic cutout, Line Locks, stock exhaust 455rwtq, 453rwhp at 14 psi 91 octane.......684rwtq, 681rwhp at 24 psi running flex fuel E60 at time of dyno tune.
I only use steel hard line for long runs. I know it can be difficult to add hardline so, another possibility is: Some cars already have a Steel feed and return, and some also have a 3rd larger line for the emission canister (charcoal canister or evap/purge). These lines may be 5/16 or 3/8".
Because there are three, if you tied the two 5/16" lines into an aeromotive regulator it would have (pie*radius^2+pie*radius^2) or (£(5/32)^2+£(5/32)^2)" = .15339sqin
Where as
10AN
£(10/32)^2 = .3067sqin
8AN
£(8/32)^2 = .1963sqin
6AN
&c = .110
7AN
&c = .150
If you had a 3/8" and a 5/16" it would be:
£(3/16)^2 + £(5/32)^2 = .187sqin
a -7AN+ line is already there, steel, plumbed for you to a regulator in the engine bay, hose clamps and braided hoses for short runs, its cheap and track legal.
Fuel calculator says 1000cc + 6cyl around 50psi base is 750bhp

search reveals -8AN supports 700+rwhp which would be 820-850bhp already and morehttps://ls1tech.com/forums/fueling-i...e-support.htmlThe mechanical pump I use has a -8 in and out. It feeds my engine at 40lbs boost with 100lbs fuel pressure.........
http://www.460ford.com/forum/42-gene...0-support.html"in Theory" a -8 line will flow 337 gph, now this is a dead straight line 100ft long without fittings, connectors, etc. Now, in the "real world" I've got customers that have supported up to 1700 hp (single turbo SB Fords) with a -8 line from the fuel pump up to the fuel rails. It all depends on how efficient your fuel system is as to how much fuel it will actually flow.
It all depends on the pressure.
An 8AN line would flow a hell of a lot of gas at 16 PSI. A lot more than 600 HP worth, that's for sure.
Now, at 2 psi, maybe not so much.

with respect to 3/8" line (6AN):
http://ipgparts.com/blog/fuel-line-s...ize-do-i-need/The key to sufficient fuel supply is pumping power. As another example let’s look at a flow of 1 gallon per minute at a required fuel rail pressure of 70 psig. That is enough fuel to support 720 HP. The pressure drop thru a 3/8”id line at 60 GPH is less than 1 psig! Switching to a ½” id line would result in a pressure of about 1/10 of the 3/8” line. However, given sufficient pumping power, a one (1) pound drop versus a tenth (1/10) pound drop is insignificant. At 500 HP the pressure drop is even less.
