R35 E85 Roll Call....

[handbrake]

Hey Domino

i use only sucrogen E85 in the big red drums. more expensive but 100% consistency in quality.

I only drive it on the track but the car runs/performs flawlessly

I have ID 1000cc injectors and Walbros

if anyone wants to see whats actually involved...

Diy injectors

Diy fuel pumps

I'd go the Deutschwerks pumps instead of the HKS. http://www.speedfors...1.html?cPath=96 $338 vs $740 for the HKS and supposedly a drop in replacement as well. No happy about that bit with the HKS's about either having to grind the pump body or pump housing to make them fit . Would be interesting to see if you have to do the same with the DWs.

As far as Ethanol percentage goes I guess as long as you know what you've got in your tank whether it be 60% in winter or 80%+ in summer then I'm sure you can have a couple "intermediate" maps set up with your Cobb AP so you can select based on the mixture of your ethanol/petrol blend. It wouldn't be hard to knock up a simple dash meter to convert and display the PCM signal from a COTS flex fuel sensor to tell you what you've just pumped into your tank and select your map accordingly...If only the ECU could accept this input and do it for you! Or are you just better off just watching your fuel trims and selecting maps based on this?

That's good about the ECU reporting the correct flow rates as well Martin. I like the idea that the conversion doesn't leave you with small compromises such as losing some of the factory niceties such as accurate displays. Once the warranty is over I think this is a must do conversion!

Have any of you guys considered running 98 on the street and buying drums of E85 for the track? You can pickup a 200L drum for about $500 and its FAR better than the crap out of the pump they claim is E85

Why would you pay that much for E85? If the percentage of ethanol is important (for competition purposes) I'm pretty sure you can get 100% ethanol (4%? denatured) for just around a buck a litre and make your own E85 up yourself.

Re hks pumps I agree

That Diy link is just to show what's involved in the install

I personally would go dw injectors with dw pumps just to keep that consistency bw parts

Fungoolie, contrary to the info supplied on the web the DW's are not a straight drop in replacement. I've had a couple of sets now (800cc & 1,200cc) and both times we've had to make some modifications to get them to fit correctly.

Oh so the injectors as well as the pumps arent direct replacements either? Thanks for the info Slip. Does anyone knopw of any injectors that just drop in? Or is there always going to be some mechanical or wiring adapter mods required?

that's odd, my DW 950's fit straight up, no mods required.
