xtremerevolution Posted October 30, 2007 Report Share Posted October 30, 2007 What will it take to get my L27 to run it. This shit goes for less than $2.30 a gallon around here compared to the $2.80 for regular gas. I'd seriously love to know if I can run it, and if not, what it would take to run it.

pwmin Posted October 30, 2007 Report Share Posted October 30, 2007 bigger injectors and a tune, possibly some other stuff. you'll be able to run a shit-ton of timing and not get any KR Quote Link to comment Share on other sites More sharing options...
GP1138 Posted October 30, 2007 Report Share Posted October 30, 2007 It's also a lot less efficient, it's been proven. It's almost not worth it. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted October 30, 2007 Report Share Posted October 30, 2007 It's also a lot less efficient, it's been proven. It's almost not worth it. x2. It's like spending 3$ a gallon and getting 30 mpg, or spending $1.50 a gallon and getting 15 mpg.

pwmin Posted October 30, 2007 Report Share Posted October 30, 2007 actually, if you can boost the timing up a lot, you wont need as much fuel (wont have to step on the gas as much) to get the same power which will result in better fuel economy which could negate that effect. it's 1.00 a gallon less here. ive been thinking about this, too. intelligent ethanol systems makes a kit to convert to E85. it has a switch so you can go from gas to E85.

It's like spending 3$ a gallon and getting 30 mpg, or spending $1.50 a gallon and getting 15 mpg. Disclaimer: That was just an example from my head, numbers represented are not accurrate representations of actual retail situations. from everywhere I'm reading people claim better gas mileage on turbo engines and lower on N/A engines, about as low as 33% lower. That, however, is only because the PCM can't properly read something that's going on down there. If its not worth the trouble, I won't go into it much. Would it be safe to run a higher than 10% mixture though? Like a 25% mixture? Pump 10 gallons of unleaded and 5 of E85 (giving you 11 gallons of gas and 4 gallons of ethanol)? Granted, that would probably only save you $10 in a whole month, but hey, that's $10 extra to put to something else. actually, if you can boost the timing up a lot, you wont need as much fuel (wont have to step on the gas as much) to get the same power which will result in better fuel economy which could negate that effect. it's 1.00 a gallon less here. ive been thinking about this, too. intelligent ethanol systems makes a kit to convert to E85. it has a switch so you can go from gas to E85. How much is that kit? Is that universal? If I could indeed change the timing to use E85, it would be quite worth it. $1 less a gallon is...damn...$15 less per fill-up. I fill up once a week, which is $60 a month. That's my electricity and gas bill combined... Quote Link to comment Share on other sites More sharing options...
pwmin Posted October 30, 2007 Report Share Posted October 30, 2007 at $600 its not really worth it for most people, imo, unless youre doing it to save money on fuel and help out the environment at the same time. intelligentethanolsystems.com Quote Link to comment Share on other sites More sharing options...
itsdave Posted October 30, 2007 Report Share Posted October 30, 2007 Most important thing about e85 conversions is new fuel lines AFAIK. I guess older engines may need more tlc than that. Quote Link to comment Share on other sites More sharing options...

intern8tion9l Posted October 30, 2007 Report Share Posted October 30, 2007 We dont even have E85 here and Gas is at $3.02 false. there is a station that sells E85 over on washington ave. i always meant to get over there and fill my truck up just for kicks to see how it runs Quote Link to comment Share on other sites More sharing options...

Because if it ISN'T you, WILL be on the back of a hook going to the nearest repair shop. E85 in a regular vehicle = all kinds of lean codes and a non running vehicle............... As for fuel econ: Flex-fuel E85 vehicles (such as some newer 5.3L C/K trucks and older 2.2L S trucks) usually see 25-35% WORSE fuel economy when run on E85...........and that's on vehicle's whose PCM's ARE tuned decently for it. Basically, I have a VERY low opinion of E85 for regular use, although quite a few turbo guys ARE running it successfully and enjoy plenty of benefits. But again, most of it's in the tune. Also, be aware that Ethanol corrodes a LOT of different plastics and metals, and the longevity of a fuel system NOT designed for E85 that has been converted may NOT be all that long.

GutlessSupreme Posted October 30, 2007 Report Share Posted October 30, 2007 E85 has a lot less energy per gallon of gasoline. Period. You will see a decrease in fuel economy and you're not going to gain it back just through ignition timing. as BIGBULS said, E85 can benefit turbo vehicles in the power department (I forget the reasons why), but your mileage will still not be as good. Better when compared to an N/A vehicle, but still not as good. Quote Link to comment Share on other sites More sharing options...
pwmin Posted October 30, 2007 Report Share Posted October 30, 2007 you may not be able to get ALL your mileage back, but its not unheard of to go from 30mpg in an L67 to 35 w/ just bumping your cruising timing. Quote Link to comment Share on other sites More sharing options...
z34Phoenix Posted October 30, 2007 Report Share Posted October 30, 2007 on the DHP site people have talked about it and barely a handful have done it. yes you need to remove all the rubber lines in your fuel system, your fuel pump needs to be upgraded cause the parts inside arent able to withstand the fuel. bigger injectors rated for e85 the normal metal fuel lines should be able to handle it. and plenty of tuning... the benifits of runing e85 is the much higher octane. its like runing race gas... and race gas is like what? $6 a gallon now? prob more. so yeah if i need to spray 20-30% more fuel (be it e85) to get the needed fuel, then MPG prob wont be so great, but this conversion is more for dealing with KR issues and runing more timing for more power.... and when high HP is your goal who cares about mpg for daily drivers.... prob best to stick to 93 and save the money that you would spend on converting. i know if they sold e85 in daytona i would be working on getting my Z runing it. but thats just me. i guess i could always carry the laptop and if i had to go back to 93 from e85 i could just flash a new PCM file with the correded injector flow rates to compensate for the fueling... got to remember too... these flex-fuel cars are new... and mainly aimed at economy and not HP. when the big boys start working on a flex-fuel Vipper or Vett then the true benifits of it will trickel down to us all.

xtremerevolution Posted October 31, 2007 Author Report Share Posted October 31, 2007 Or you could buy a GM car that can use E85 I drive a 95 regal with 161,900 miles (as of today), and spend a great deal of my time making sure it runs like a clockwork in perfect shape without a single fluid leak. Unless I managed to save the founder of GM from a car wreck and he makes me a 90% off deal on a new car, I'll be driving the Buick for another 50,000 miles at least. Oh yeah, and I'm a senior in college. This is about as low as it goes. Quote Link to comment Share on other sites More sharing options...
