Running on E85?

Found M60 E85 build here - http://www.youtube.com/watch?v=THL1n7_lZDY
I'll contact the owner to get more info on how it's running and maybe a dyno sheet?
A deafening roar from the rebuilt 4-liter V8 (M60) when it is started after the rebuilding to 100% ethanol (E85) operation. After a 1.6 mm face milling of cylinder heads is the compression ratio now 12.5:1 (original 10:1). Completely rebuilt fuel system for higher fuel flow and pressure. The fuelsystem has now installed BOSCH EV6 injectors, that flows 42 LBS/HR (436cc/min) with E85 fuel. Original fuelinjectors flow 19 LBS/HR (191cc/min) for petrol. Fuel pressure set to original 3,5 bar (51 psi). It has a old engine optimization for Shell V-Power petrol. The motor control will be re-optimized for the E85 fuel.Mtech1 v8 build thread - https://www.r3vlimited.com/board/sho...d.php?t=413205

you're going to need to tune for it. stoich on E85 is significantly richer and you need something like 40% more fuel. that's way outside the DME's adaptation range.
the advantage is you can run a higher CR/more boost, and it's sometimes cheaper (in europe it's heavily subsidized). The disadvantage is you'll use a LOT more fuel, and it's not available everywhere.
for an N/A motor, I'm not sure it's really worth it. On a turbo it can make a huge difference, because you can run more boost, more timing, and a higher CR. on an N/A motor, going from 11:1 to 12:1 is a pretty small difference power wise, and you might not be knock limited on normal gasoline to begin with.
Is E85 cheap/available where you live? what if you leave your area?

Yep, it's available locally. I am just sharing what I am finding on this and maybe someone has done this before like the guy in the youtube clip :) I've sent him a message to see if he's got a build thread and a dyno.Mtech1 v8 build thread - https://www.r3vlimited.com/board/sho...d.php?t=413205

The easiest way to do this would probably be to run a standalone capable of supporting a flexfuel sensor. You can of course recode the stock ECU, but that takes a significant amount of skill and could be expensive. Plus you are stuck with one tune that only runs on one kind of fuel - a flex fuel sensor will automatically adjust fuel/timing (and possibly even boost) based on ethanol content.

Makes sense. But what needs to be "prepped" on the engine side/ fuel system side to make it E85 friendly if possible
One can posible have a spare DME for this, cheap and easy way to switch between the two if needed, for say smog or emissions?
What does running E85 do for emissions?Mtech1 v8 build thread - https://www.r3vlimited.com/board/sho...d.php?t=413205

Regarding E85 and emissions, they're much larger when the engine is cold (especially on cold-starts from -20c etc..) but I guess that's not a problem in California :)- E34 M5 (x 2) -

M60b44 should be no issues for the m60b40 dme to fire up/test driven.OBD1 M54/M52TU swap as a M50b25
