Okay, so the is is an impeller upgrade. Is this something you just buy and it gets replaced during install or do you have to send it our to vortech?
I doubt I would run e85 with the SC. Between my 4.08 gears, the SC, and e85, I'd probably be getting 10mpg which I now we shouldn't care about butt hat's just way too low.
I know mpg depends on your driving habits, but with SC, you're almost always in some amount of boost since it's belt driven. Also, since the power come son gradually, I might even keep my 4.08 gears. With tt, those gears would def be gone and you can stay out of boost easier. The downside is $$$$ and more maintenance. I wihs I cold get a ride in a SC and TT z.
