ok i have mods in sig 2.8 60's dualpass intake header exhaust

my question is are 60's enough to run E85 on my set up got a tone of spots to fill up down here and people are saying i can gain 10-20 hp just dont see a down side

also will it need to run it till its low and then have the tuner do the base tune for it when i fill up with E85

thanks guys

 

im pretty sure youll need minimum 80`s

 

i have their set up on e85. u need 80lbs tho

 

im sure it dont get very cold where you live down there in AZ.
thats your advantage. E85 sucks in winter up here in MO. or i would be planning on doing the mod next summer... might still consider it tho.

 

its cold here sa a bit and the idle sucks for a lil while then all good lol

 

but will 60s work or will i need bigger injectors i heard 80s where for e85 on a tvs i was just wondering what min would be the stock supercharger

 

You will need 80's for your setup. 60's might work on a stock pulley, but not on your setup

 

lol noob question what would happen if you mixed 91 with e85 lol could u get a mid run of better hp? just wondering

 

No you would get somewhere around 98 octane (assuming half and half mixture) that would be extremely inconsistant causing your tune to be off by a huge margin every time you filled up since you would never get a perfect mixture. I would stick to one or the other.

 

either do the full swap or not at all it aint worth the risk

 

I love that people are doing e85. hope it works out.

 

Its one or the other.

You need 80s. End of story.
