I know this guy who is telling me that, he is gonna make 750hp with just adding a supercharger. I don't believe that can be done without headwork & cylinder bore and better exhaust. Any Comments on this guys ?

Automatic 5.0

I know a guy that put down 678 at the rear wheels with a supercharger on his 2012 Boss. It really wasn't a stupid amount of boost either, like 8 pounds or something like that.

Nothing needs to be done to the engine on the boss, its good to go.

Twin turbo setup can easily get you 700-800hp to the rear wheels.

So it could be possible with a vortech or other centerfugal superchargers.

A member here has done it with a Vortec blower. Should be no problem on a stock Boss motor. I would put headers and exhaust on it though.

Boss's already have head work, and as many have said it seems to be really easy for them to make power if your forcing air into them.

Sounds like Boss has alot better internals than a GT ! I think he said he was using a BKM or something like it.

Guys, does the Boss 5.0 engine have forged internals, ala the 5.4 or 5,8 shelbies?

Automatic 5.0

I think pound for pound boost wise, a Boss 5.0 puts out more power than the 5.4 in the GT500.

Dammit I knew I shoulda bought that white Boss, jerk dealership wouldn't take my trade-in

My mechanic put a custom TT on his GT. Only other performance mods were the boss intake manifold, cat deletes, and GT500 mufflers. He made 700+whp and 750wtq. Stock internals. I'd imagine it could easily be done on a boss which has better flowing heads and slightly bigger cams.

Types... you see my post above? Is the Boss engine forged? if so, what's the limit? I know the aluminator crate engine is 1500hp. If I ever upgrade mine, it would be that.

AlsCobra

Yes.
Only difference is they are not hand built by the SVT builders.

Interesting to know; Do you guys know what's the hp limit is for the boss stock internals?

Brandon302

Don't know if it has been seen yet, think JPC built a 1200+ wheel Boss and it may have had stock internals, http://mustangforums.com/articles/20...horsepower.php couldn't find the actual article.

Thank you for this. That was refreshing. What's the details on the mods? Can't "just" be the turbo.

So if I wanted 800-1000whp, what would I need to do?

crate engine
FI setup and tune
tranny
rear end

what else?

AlsCobra

Buy a Boss and slap a 2.9L whipple kit on it. Headers and a tune and 800 should be possible all day long.

FromZto5

Will the tranny and rear end hold that? Esp if I don't track or race

http://www.svtperformance.com/forums...+turbo+Boss%27 here is the info from JPC. I believe they say the owner still has the stock MT82, not sure if it is upgraded. I would upgrade internals but keep an MT82 for that much power since it is cheaper than a T56 Magnum. You could probably buy Boss heads with better springs and valves and some better internals rather than a brand new crate engine.

AlsCobra

Hell yeah. If you drag race and use slicks, you're gonna snap something but it should be fine otherwise. It will require drag radials or road race rear tires to even enjoy the car though. I believe 800 is a reachable goal on the Boss though. I recommend a large blower though. 2.9-3.4L blower just to keep boost pressure down as low as possible and still get tons of airflow. Turbos will work also but it's just a lot more work, heat, and tuning issues. Along with exhaust restrictions that I personally don't agree with.

Brandon302

You have heat issues with SC's as well, what exhaust restrictions do you mean on turbo's?
