Turbo Fuel Requirements

[WVTurboLTX]

So I'm looking through the documentation that came with the MPI trail turbo kit. The pages that came with the EABC says that it maintains 5 psi at sea level and it is not uncommon to see it go to 8 psi at higher elevations. At the same time in the install instructions for the turbo it lists fuel requirements and states that 5 psi needs 50/50 premium/race gas at sea level. Is everyone running turbo kits on the trail with stock internals and 5 psi carrying race gas to mix with premium when they stop to fuel up? This seems pretty unrealistic considering I know a lot of people run 250+ miles per day. To do this you would have to carry around 10 gallons of race fuel......

Id like to know as well. Maybe Matt could chime in and settle this.

I heard that with any of the turbo kits 91 octane should be fine at 5 psi.

For alittle precaution I started mine off with a 1/1 blend of race gas 101 and our super 90 octane and I could not get the sled to fire once temps went into the negatives. So I've backed way down to a 10% race fuel blend and it fires right up at -10f now. I,m only running stock boost 4.5-5
I was told we can get away with 100% pump gas once we take it to the hills 2000ft or more.

I sent an email to matt asking a few questions about the kit. He said you're fine running premium. Everywhere I run the premium is 92 or 93 octane. I plan on carrying some torco with me just incase I get stuck somewhere without premium.
