I just bought a Roush Supercharger for my 2012 5.0. How much boost should I go with?

Might wanna look more into why KB cools the front. Its actually a pretty nifty concept.

Whipple....170° AFTER 2. And KB had to liquid the front bearing support LOL. He said it was called "Delta T"


Roush has the largest charge cooler core for the 5.0 too. You have to rotate the knocks sensors and reroute the wires to not pinch them because the tub is so big."
I went out and did some 0-60 pulls, and got out and my supercharger was cooking, i couldn't put my hand on it... so I guess that idea is out. ha ha but intake temperatures still haven't got about 110 at idle and nearly match ambient air when moving. It's only about 67 degrees out though. Yeah, I don't know much about TVS, I just know my whipple was always hot after 2-3 pulls.

How robust are the forged internals in the boss motor. I would like to see some pic's of the rods and pistons.

Unlike the douche who replied to your comment first, I'll hopefully be of some help.

Here's a link on the Boss 302. Shows pictures of the internals and gives great information.

In terms of robust, I wouldn't push the Boss rods and pistons past 800-850rwhp. The crank can handle up to 1,400hp from what I've read and discussed with vendors.

Thanks bro.
I expected a little more meat on the Boss rods.
I'll probably put some H beams in mine.
As far as the douche goes, Probably a napoleon complex.

Actually, I made that comment because I saw your original post correcting the guy by saying "it's a cast block with forged internals" even though you knew what he meant. I can't stand the forum idiots like you that feel the need to correct everyone

How much HP do you think the Coyote valve train can handle? I don't think I'd go over 750W -800W anyway. Thanks

I wouldn't push a Coyote with stock internals and valvetrain to beyond 725-750rwhp. Too many things come to mind that could go wrong.

You think 700WHP is safe on a Coyote? I don't know that.


I have a Boss 302 block but have the Coyote valve train. I heard that I should probably swap out the valve train if I wanted to go over 750W or so.

There's plenty of guys running the stock valvetrain and are pushing almost 700rwhp. I know of one for sure over on SVTP that's pushing 706rwhp and is upping his Procharger boost this Spring. My personal choice, I'd upgrade the valvetrain at the 700 mark. Here's a link for a company that just released new valvetrain components for the 5.0 motor. Beehive springs, Titanium retainers, etc. I'd give them a call and go from there.

Here's the story they did on StangTV.

Does any one know what valve train the Aluminator uses, and is that the engine in the Cobra Jet? I assume it is.

Wasn't correcting anyone, Some people actually think a forged bottom end means a forged block. Of course what would you know.
And I can't stand idiots like you, who think they are something their not.
Get a life.

The Aluminator uses Boss valve springs, GT roller finger followers and GT valves. Also, the Cobra Jet uses the Aluminator.


Quick Reply: I just bought a Roush Supercharger for my 2012 5.0. How much boost should I go with?
