Im setting up an e85 tolerant fuel system for my car to support 700hp, my plan was to run an 044 off an alloy surge but I wasn't sure if I should go stainless. What materials are people using for their e85 surge tanks, if alloy can it just be anodised, or is bare alloy fine?

Also, Bosch don't seem to recommend their pumps for ethanol, are there some available that are recommended? I'm running a Tomei 33 gtr pump at the moment with no issues, this will remain as the lift pump. Will one 044 flow enough ethanol anyway?

:devil:

I definitely don't want to blow $1300us on a pump. The engine internals are costing less than that. Worst case twin bosch 044's would be $400.

Anyone running ethanol actually checked their alloy surge tank? I made a small alloy primer tank which has started corroding with just petrol in it.

well how big is your turbo? how much psi are u running? these are things that i have come arcoss on my e85 set up. im currently on t72 with twin pumps with a relay and that is working on my set up at 600 hp.

I havent built the engine yet. Its a VQ35, will most likely have eagle rods, CP pistons and a GT35 external gate. Im building this engine slowly as a backup, just trying to sort out the fuel system first.

it's extra money and effort to be legally able to recommend you equipment for ethanol. it needs to be tested an engineered etc. at the moment it's a small part of the market so companies aren't bothering.

anything that is methanol compliant should be fine

:D

you are most likely going to have to have 2x 044 pumps and 1600cc injectors to give some headroom.

    • Pete knows these cars well, he does my car too, if he was concerned about the traction arm length for your use he would have said so. Do you have adjustable bushes in that arm, maybe he got enough adjustment there (or maybe the bump steer was not material for your use of the car)
    • Hmm. Yes. I should have been clearer. 1000s for Haltech, for extra headroom. 725s for Nistune. You might even be OK with 640s, but if the possible power ends up much more than 300 rwkW you will run out of headroom on the 640s. That would probably be OK and a signal to not push it to that sort of power with Nistune anyway. At that level you probably do want to be thinking about engine protection functions. Oh, and all of that presumes 98 only, not E85. Well....the 1000s would allow you to run E85 at ~300rwkW territory, again, maybe sort of running out of headroom. Hard to tell with E85 - depends on the tuner as to how rich they like to set it up.
    • Yes.  The only scenario I can imagine when the answer isn't yes, is if you drive like there is highway patrol behind you at all times.  If your car currently runs, enjoy it and keep saving. Better costs more, keep saving until you can budget the better ECU. It's worth it.  Nope. Plenty of us making >300kw on unopened motors. Mine is unopened and makes about 350kw if I turn everything up, its fine (lots of caveats here, how the car will be used/abused, how long you expect the engine to last between rebuilds, how has the engine been maintained prior to coming into your ownership, etc etc).   
    • Sorry just wanting to clarify, at this power goal, which should I be going? Also, More info regarding suspension, the rear upper camber arms were used to get the camber back to i believe around -0.5 ~ -1 degree (@ Road and Race in Rydalmere), I forgot the exact figure, but ALOT less camber than what it came originally which was like -2.5degrees. Are the traction arms still recommended? The bilsteins from SydneyKid, they've got 400lb/in fronts & 275/in in the rear, revalved to his specs. Intercooler, I'm just having a look at some on Rakuten.jp and some other japanese sites. Might get something from back there, GReddy, Blitz or HPI, all crossflow. Looking at roughly $450-$500 AUD + shipping... Theres not many choices except that chinese branded Justjap unless you go for blitz return flow. Yeah, only downside with Haltech is the price ahhaha, so expensive, and with all the sensors if I go that route... $$$$$ yeesh. Are headstuds/gaskets needed for <300akw?
