For those running e85 straight out of the pump, not even checking consistancy...have you run into any problems? Mostly concerned about 500+whp setups.

 

Speaking of consistancy at the fuel pump, here is something I have thought about. At most gas stations now-a-days there is a multi-selector for the octane and then there is one physical hose. So you pull up and select 93 octane. Well, more then likely the person before you bought 87. So that would have to mean that when the gas pump starts pumping 93, it actually has to push out any 87 that was still in the hose. So depending on where that 3 way split is inside the pump, you could actually get a 1/2 gallon (or maybe more) of 87 octane when you fill up.

PS, I wish we had E85 here in Dallas/Fort Worth in any practical quantity. I have to drive 60 miles each way to work, which is about 5 gallons round trip for me and I only have a 8 gallon tank. So E85 would have to be pretty easy for me to consider switching over considering I would be getting even less range.

 

im on e85 and close to 500hp i get my gas straight from the pump and had no problem. one little advice is once you fill up your tank run the car for 10 min or so before you step on it. ( you want to warm up the e85) and you should be golden.

 

Where im at the E85 runs all out of a seperate hose. If you use a wideband air fuel gauge just keep your eye on it.WOT should be x, idle should be x, and part throttle should be x. When you get tuned on E85, just remember what af ratio you should be at at certain rmp ranges. Even in my NA car I noticed the E85 likes when the motor is fully warm, anything less it gets a bad hesitation, and stutters quite a bit. Where I am they switch the pumps to E70 in winter due to hard starts in the cold, which actually reads more rich than the 85, so instead of running lean it will be a little fat, and just feel sort of sluggish. If they dont change to a winter blend where you are it should be fairly consistant.

 

we fill up 55gallon drums
it last about a month for two cars

if ur useing a s300 put in a wideband and setup lean cut.....

 

nope never had an issue with it out the pump at all, and im straight out the pump
