M85 is about as powerful at E85, but retains most of the down sides of methanol, ie it is toxic, more corrosive, and requires even more fuel than E85 to make a usable mixture. CNG is good in theory for things like busses and trucks around a factory campus but has problems on the highway. It is high octane but has no cooling effect like the evaporative cooling provided by ethanol. CNG must be converted to gas at the injection point and as a result displaces lots of air in the intake manifold with vapor, cutting down on the maximum power available from the engine unless special efforts are made to improve breathing to compensate for the loss in volumetric efficiency due to vapor displacement. Natural gas conversions are the reason it is illegal to convert gasoline cars to alternative fuels. Back in the 1970-1980's there were lots of NG and propane conversions done, and they produced a lot of nitrous oxide emissions due to their high combustion temperatures. Both fuels have use in specific locations where their disadvantages are minimized but E85 and ethanol has all the advantages that both fuels claim with very few down side effects. Larry

Alcohol compliant Fuel Filter
Just as an fyi since it appears E85 is drying out the rubber material in our fuel filters.

How many miles were on your OE filter? I changed mine at 60k, just like the owners manual says. I went with the OE replacement filter from the Subaru dealer when installing my Walbro 255.... no problems to date but I'm always interested in findings. So you think the all metal filter is better?

I'm still waiting for JSarv to crack his open and share his findings as well. I do urge all E85 users to strongly consider upgrading to an alcohol fuel compliant fuel filter. It's great insurance and piece of mind for not that much IMO. |

Since we're talking about filters, I guess I'll post what I'm using.
I have 2 filters. A 100 micron 10an filter before the Bosche and a 40 micron 8an filter before the rails. Both are stainless mesh. The main filter is a KRC filter I got from eBay. I'm thinking that 350gph should be enough flow... This is the 40 micron filter: They have them available in barbed configurations as well. The filter is flat, so I don't think it would work as the only filter unless you clean it frequently. I only added it because I wanted to catch particles smaller than 100 micron or pieces of my fuel pump if it ever failed. It flows 135gph. Last edited by bluescoobywagon; 08-27-2009 at 09:52 AM. |

One thing folks should take careful note of about the Golan filter is the clear annodizing. It should be obvious, but you really don't want to expose raw aluminum to an ethanol blend, no matter how good you think it looks. (The screams of "it's corrosive! omg!" are way overdone, but you will definitely end up producing some undesirable material over time that you really don't want in your injectors.)
Obviously, note the seal material as well, but I think everyone is pretty aware of that. When I see what looks like a raw aluminum filter being pushed as ethanol-safe, though, I get a little nervous that people will miss the very important note about annodizing it, and think those cool-looking polished aluminum fuel rails and bare aluminum AN fittings are just fine. |

That was one of my reasons for getting the KRC filter. It's hard anodized inside and out. My Aeromotive rails are also anodized inside and out. Some ebay rails aren't anodized on the inside because they're not truelly anodized, but have just been dyed instead. The reaction with aluminum is why I need to get a custom made stainless surge tank. Every tank I could find was bare or polished aluminum... |

So it appears that hard anodized aluminum is alcohol safe and is probably the way to go. However I asked a few DSM guys that have been using these same clear anodized fuel filters as soon as they hit the market and they have not reported any corrosion whatsoever.
That being said, I would think that clear or hard anodizied aluminum is E85 safe. But that's just what I think. I don't know if this is 100% true. If I do see any signs of corrosion or if I don't, I'll report back. Hard evidence is better than speculation IMO |

What I'm warning about is the urge to look at these filters, see the shiny aluminum, and then proceed to litter the rest of the fuel system with bare aluminum like non-annodized aluminum fuel rails, AN fittings, fuel cells, etc. The filters Jay is selling should be just fine, but not all shiny toys are made the same. |

I have not read this whole thread and I expect the answer is in here someplace (but I did not find it) Can someone summarize their best tuning guidelines for a good cold start and E85?
More fuel? Less Fuel? (more but how much?) More timing during cranking? Less timing during cranking? Cheers Last edited by mick_the_ginge; 09-07-2009 at 12:20 PM. |

I answered my own question with a quick bit of tuning. Added some more fuel during cranking, removed some cranking timing. After this the car fired up quickly on the inital cold start. I'll try again tomorrow when the car is really cold again.

Do report back. I can't imagine it's that cold though in September in Oregon? Wait until January in Colorado

It was a good test. It was taking multiple tries to get started before, not it fires up on the 2-3rd rotation which is pretty typical. I'm sure it will get harder when in gets colder.

I richened up my cold start quite a bit and it really helped. I tried playing with the timing, but I dod not find any real benefits. BTW, "cold start" for me means below zero F air temps.
