Better fuel milage with 3.5tt or 5.0 Supercharged
#13
I think if I did this I would get really bad MPG on the 5.0 simply for the fact I could not keep my foot out of it... AT ALL!!! LOL Honestly just do the 5.0 supercharge show pics here so we can all drool over it...

The epa rating on the 3.5eb is about 10% worse than the 5.0. My experience is that the whipple knocks about another 10% off of that even driving conservatively, so you're looking at 20% worse mileage, or 4 mpg. Now I've always been able to get good mileage out of a vehicle so take this as such, but I'm 500 miles into my current tank and averaging 20.8 on pure gas with the whipple.

Yes you need premium fuel. I had a Whipple on my 06 5.4 and the mpg was the same as naturally aspirated as long as I didn't get into boost. When you're in boost, naturally more fuel is applied. The boost is addictive and you won't be able to keep your foot out of it.

I recommend Googling for "problems with Hennessy" before considering.
