any one runing e85?
|
it takes a lot to run e85. the entire fuel system has to be swapped out and an aftermarket ecu put in and a good tune done for the different octane.
|
What if you're running a carburetor?
|
We actually recently had a discussion in the general area about running e85 in carb'd outboard engines. Phins was running e85 and it caused varnishing inside the carb and restricted the flow of the jets
|
Very interesting, cause i've actually been considering trying it myself.
I wonder why it would cause varnish in the gets? I would think it would leave the carb much 'tidier' and clean.. even burn cleaner. Not that any of us rotorheads are worried about the enviorment>> Lol. |
Carbs seem to be more of an issue then fuel injection. The big issue is if ethanol sits for more then a week, sometimes phase separation occurs, it also absorbs moisture from the air (in the tank) and as mentioned my issues were/are massive amounts of varnish in the carb float bowl and jets.

Now that makes sense.
Still wanna give it a try to see what it does. https://www.nopistons.com/forums/pub...IR#>/smile.gif |

Used for years by USAC and many others. Flush the system with gasoline when done thus eliminating much of the trouble pointed out. Requires bigger jets, as it has 30% fewer BTUs per pound. Absorbs lots of heat so racers have very small radiators, allows for very high compression ratios even when boosted. Needs a high output ignition system. Pulls water out of the air very quickly. Flush when finished. Lynn E. Hanover |
