The unit then increases the amount of fuel for the E85, thats why cars using E85 get worst gas mileage than gas cars. Yes, has less energy then gas, that is again why we use more.
The high octane of E85 lets you run alot more timing and boost. And to answer the question about can your fuel system handle it long term(i.e. the rubber stuff). All cars since 1985 were built to be able to run on E10 and the fuel systems have just gotten better. There has never been much testing done to see if a rubber hose that can handle 10% alcohol can also handle 85%. But many in the automotive industry feel that if a piece of rubber was made to handle alcohol, it can handle alcohol at any %.
Brazil started converting vehicles over to E85 back in 1974 and has been self sufficient on e85 since the early 90's.
E85 will however clean your fuel system so anything that is in your tank from dirty gas will now be in your fuel filter. So after the conversion your will need to change your fuel filter and oil after about 500-1000 miles.
All right someone also asked the price. The kit I used cost around $450. If interested go to the Full Flex International web site and check out the videos under the news section. I think under the news 2, then scroll to the bottom and watch the videos. They have one on a year long test of a no E85 vehilce using it for over 105,000 miles.
This is not something I just jumped into I have been looking into E85 for over a year and I liked this kit the best. I will post my track times after I get home from the track, BAD OR GOOD.
Surprising.........per the Vice-President of vehicle emissions and regulatory affairs at Chrysler, The rubber parts, (o-rings, hoses, gaskets and seals), are in no way meant to work with E-85 if they've been specified for gasoline. There has been much endurance testing done on this topic. This has been a big bone of contention between the automakers and the Government agencies pushing for more widespread use of alternative fuels.
