Haven't had to buy any in a while, but last time I checked meth prices it was cheaper than 91. Also pretty cool, the meth and n2o jets are the same size if you run ford fuel pressure.

 

How much is E85/91 out in AZ?

 

93 oct here is 3.65ish
E85 is bout 2.25 i think

 

Jesus, your E85 is cheap. With prices that cheap it would still actually make financial sense to run it all the time. Filling up last night, paid 29.58 for 8 gallons of E85 and 31.00 for 8 gallons of 91. Almost the same here

 

its been awhile since i was up that way too, so it could be in the $3 range now.
but 87 here is 3.32

 

I have considered switching to an E85/87oct mixture to save a bit on the gas side, as its 25 cents cheaper per gallon. Not a huge savings, but seeing as the gasoline contributes next to nothing for usable octane it makes sense.

 

Why not spray water/meth? Works for me

 

E85 is so much easier! I have a meth kit but haven't had time to install it. Honestly haven't needed it much with the E85. Will get it on there for IAT purposes but so far its working well without it

 

E85 is $2.23 at the closest station to my house. Just throwing that out there.

 

There's a bunch of guys running E85 in a dedicated system, cheap and easier to come accross.

Man it's at 3.35 +/- here...
