Definitely not needed for E85. I'm on the bridge just how much my IC helps as I have had two occasions of complete W2A IC failure. Once a pump failure second time was the pump kill switch was off. Both times it blew off the fill cap and all leaked out. I was beating on the car both times in the summer and still never saw KR with ~20* of timing and mid teens boost.. Shows just how much of a safety net ethanol will give you. If you can tune and you are aware of the things that come with a ethanol convert car make the swap.
What I said above about IC's kinda goes out the window when I used my ice box setup. I believe that is a gain along with the E85, With that I could get my FMHE, IC and blower very cold to the touch and in turn much colder intake air. This helped me take a tenth off my 1/4 mile.
I'll post pictures of the hydro dipping.
I'll also have to take a look at those mount bolts. Did you snap off the little studs on the single bolt mounts? Seems like it would take a lot to bust those off. Did you run a upper mount?
