I think its obvious, I chose pump/meth.
The decision was very personal and I've come to learn that different setups just make sense for different people. For me, I really really wanted E85 and gave it a try, but as soon as I switched, I found out that two stations I had been planning on getting it from that were along my normal route to/from work were no longer carrying it. The only station in my hometown (Fergus Falls) is on the far end of town, the station near my house is 5 miles past it. Quickly I found getting fuel for my ride to be a PITA. I didn't care, I was happy with it. Eventually the PITA won out, I was constantly driving extra just to fill up or filling up early so I wouldn't run out of fuel, and that just made the mileage penalty worse.
I was flabberghasted by this, Jim (TalonEvo) on here makes me so jealous, he's run the stuff forever and thinks nothing of it. Well, I've come to learn that he has no less than 8 stations that carry E85 on his daily commute, so running it long term is almost a no-brainer for him, because it's 'everywhere.'
It was easy easy easy for me to try it. I had 1050cc injectors, enough fuel pump, a wideband, accurate boost measurement, etc. I could make all the changes myself and it cost me nothing. Some may argue that it cost me a headgasket but I'm not entirely sure about that to be honest.
Anyways, I LOVE the added power meth offers over straight pump, but ultimately E85 WILL MAKE MORE POWER, MORE RELIABLY. I made what I would say are ideal numbers on my setup earlier this summer, but on the street I just wasn't able to run the timing required for that last 12whp and 2° of timing that separated me from timing numbers on a comparable car. This after doubling the amount of meth/water I was spraying (950cc now) was a bit of a hard pill for me to swallow, but eventually I have come to accept it.
So, 80% of the power/torque advantage of E85 over pump gas but you get to keep the pump gas mileage. Even trade in my eyes.
Anyways, my $.02. Shane has great info on this, hopefully he can share his insight
