A lot in here that has been mentioned is both power suggestions and refinement suggestions. For instance, weight savings, drive shafts, wheels, and suspension are all about finesse and swave rather than bruteness. The way I see it: Power is cheap, refinement will make you broke.

OP, Susspension and shoes are a great start, as there is no point to increasing power if you can't put it to the ground. Then once you decide you are committed to increasing power, rather than bleeding to death from a thousand cuts, might I suggest that you just bite the bullet and go with forced induction. I realize that this will require a tune, but once you start adding up the costs of all of the other upgrades that you can do to the car, forced induction won't seem that far out of reach.

15K miles later and it still makes me a smiling fool when I punch it! :kooky:

And, the Coyote engine was designed for a supercharger. Well, except for the rods.

I would be interested to see the rate of failure of coyote's boosted at 10psi or less vs. the rate of failure of N/A coyotes. I doubt there would be a whole lot of difference there.

Which is exactly why Shelby/Roush/Ford Racing offer supercharged versions with warranties...

I had a great comparison picture of the 4.6 vs 5.0 connecting rod but can't find it anymore. They are actually surprisingly beefy and I have not heard nearly as many rod failures as I have piston failures.

I think the hardware was built to last for moderate power levels, so long as the fuel and tune are up to snuff. There are always the '$hit happens' events but those can happen anytime.

But those warranties quickly become useless when the owners become tired of the factory 'warranty-safe' tunes that come in those kits.

Duh! If you're going to invest all that money, why leave power on the table, besides, who needs a stinking warranty. If you can afford a supercharger, what's the big deal about replacing/rebuilding an engine. What's crazy to me, is investing a couple hundred bucks for 20hp and potentially losing the engine warranty anyway. Go big or go home. :kooky:

Still, with a reputable tune the failure rate of boosted motors under 10 psi does not seem any more common than the N/A ones.
