I worked for Honda a long while ago. Probably most here have never heard of their RC166 road race bikes from the 60's. If you want to hear what they sound like (employed flat plane crank in a 6 cylinder), take a listen: http://www.youtube.com/watch?v=oIJT4TXoq1A
Imagine a variation of that in a Ford. That would be a mind bender. :thumbsup
Whipple supercharger in the works for the 2015 Mustang. BHP number impressive if accurate.

How would this work? The current 5.0 is 11:1 compression ratio. Presumably, the '15 will be the same or close. A 260 or so HP increase would require at least 13 psi boost. Into 11:1? And they are going to work this magic on 91 octane?
Where do you come up with 13 psi? In theory 14.7 psi (1 bar) would double power. Assuming they are in the 420-440 range stock, 8-10 lbs should make 700 from the results I have seen on current Coyotes.
Also keep in mind that tuners can manipulate the dynamic compression ratio with the variable cam timing.
Gary, I agree with you. Those who just strap a blower on a 11:1 CR Coyote and think they are just fine don't really understand what is going on. I KNOW there are vendors out there who sell the add-on blower's but if you look carefully at Rousch, Ford Racing and Edelbrock who offer a complete 5.0 engine with a supercharger, they ALL supply their engines with 9.5:1 CR pistons. Wonder why that is? What do these engine companies (who offer a warranty on their engines) know that the add on racers do not?
And pacettr, could you explain to us what "dynamic compression ratio" is?
