Message	BTU rating of E85 is about 82,000, gasoline is about 112,000. However, if you build an NA engine strictly for E85, you use higher compression because of the octane rating of 105. That NA engine tune for E85 "may" have more torque and HP than NA engine built for gasoline. This offsets the lower BTU rating. An E85 only engine can't run gasoline cause of the higher compression. Also, E85 has higher oxygen content so the A/F ratio needs to be adjusted for that. On a turbo engine, you raise the boost level to increase the dynamic compression to get the same or more HP.

Follow Ups	Question - I have been hearing rumors that E85 - The Devils Z 08:06:10 07/26/07 Yes, it's true. They say it's pretty much pump alcohol - John@z1 08:16:59 07/26/07 doesn't matter - aliaZ 08:35:15 07/26/07 2nd. (n/m) - TheTwinZ (Peru) 09:04:12 07/26/07 it's the same with race gas.. at the same boost level - The Devils Z 10:45:19 07/26/07 not really - aliaZ 11:02:10 07/26/07 I thought I was confused but now I think I understand ..what - The Devils Z 13:41:39 07/26/07 Race Gas IS Gasoline, E85 is 15% gasoline. The - AZHeat 14:35:34 07/26/07 you're always confused... - Spee 23:20:06 07/26/07 lol ... (n/m) - The Devils Z 12:26:17 07/27/07 I thought it was less effieciency not less energy(power) (n/m) - Jonez 13:41:00 07/26/07 how do you measure efficiency? (n/m) - aliaZ 15:12:03 07/26/07 You'll need about 30% more capacity fueling system - BOOZTD 3 09:05:07 07/26/07 Is a new ecu fuel map needed as well? (n/m) - spyhunterTT(nj) 09:25:32 07/26/07 well what do you think if it has less BTU's than gasoline? (n/m) - AZHeat 10:01:22 07/26/07 LOL @ Cheaper. (n/m) - Zluster(Abudan) 10:56:05 07/26/07 Cheaper than race fuel and most of the time cheaper - AZHeat 14:19:01 07/26/07 Thats true. - Zluster(Abudan) 22:08:46 07/26/07 Ethanol in its pure form has 30% less energy per gallon - TheTwinZ (Peru) 09:31:53 07/26/07 BTW, E10 (10% ethanol with 90% gasoline) is a safe mix... - TheTwinZ (Peru) 09:47:10 07/26/07 that's what we have here in new york. (n/m) - stockplayerz(nyc) 11:27:29 07/26/07 2nd... there are corrosion issues in the combustion chamber - CaliguyPurdue (redesigning) 11:35:28 07/26/07 Tune the engine for the type of fuel you run.
