Does anyone know what type of supercharger Ford uses on this car.....manufacturer and type?

Also, what’s the max HP on the stock internals?

Thanks....

in 2011 they still used the M122, same as the07 and up to 2012. in 2013 they used the TVS trinity 2.3 with the 5.8 motors.
don't know max limits but i know several people running a little short of 1100 RWHP without problems. i hopefully plan on doing the same.

Yeah, you're not gonna run 1100 rwhp on a stock bottom-end GT500 engine, of ANY year.

STOCK INTERNALS are good for about 725-750 rwhp, with GREAT tune and fuel.
No more than 19psi.
Anything more than that and it needs beefier rods

not really a tech question... however, I'll leave it here, OP please review the posting rules.

To your question - Gabe's spot on above.

the blowers are Eaton twin screw type of supercharger

the rods won't handle that much power. the pistons and crank can.
the piston from this link, http://www.s197forum.com/threads/genuine-gt500-paperweight-conversation-piece.134844/, was making a little over 1000 rwhp on pump gas with the 100% stock bottom end and a whipple 4.0 supercharger, 25lbs boost on pump 93 octane. the key is low RPM's. you can't rev past 6K.
i know 5 people pushing 1000+ rwhp on stock crank and pistons with good rods. they are using a cast iron block.

I’m looking to bump my FWHP to about 650-675....100 to 125 increase from stock, so I think I’m good with stock internals, according to you guys....so, what’s the best approach for that type of upgrade?

Thanks again...

Get a used '13-'14 TVS blower, leave the stock pulley on, get a Ford Racing twin-65mm throttle body, '13-'14 GT500 injectors and a new tune.
You'll easily be over 600 rwhp which puts you over 650-675 crank-hp.
