Fourcam, you forgot the link to the GT vs. STi.

Anyway, I think I would rather see a TT set-up than a roots blowing at 20 psi.
I agree that I suspect there is much more potential when using a TT application, but just knowing that the roots has this kind of potential with a pulley swap makes me giddy!

BRAD, we need more info.

Watch, he comes in and drops this bomb, now we won't hear any more about this for months...

Wow, now THAT is almost surreal!!
I believe it! :worship: :worship:

Can I ask a question? How many #'s of boost were used to produce that? 18#? 19#? Will the stock internals take that?
Crispy,

I would listen to Fourcam, the guy knows his S***.. He always has a valid agruement and unlike others, he bases his agruement with factual info.

Besides I don't think he wants a GT500, since he just upgraded his cobra, which makes me believe him more..

That's because you have no idea what a forced induction 5.4 with GT heads can do. FWIW, the GT and GT500 have the same displacement, same heads, same static C/R, same cams or very near the same cams, and positive displacement blowers. Bottom ends are composed of diff. components, but as long as the C/R is the same the parts are irrelevant, they either handle the power or they don't.
Here's a link to a vid of an otherwise stock Ford GT with a 20psi pulley (making 635rw on a Mustang Dyno or over 675rw on a Dyno jet) smoking a 600aw HP STI.
As for the integrity of the shortblock. The iron non NVH blocks can handle 1400HP+, stock forged cranks again 1400HP or 8000rpm (any higher and you want to go billet as forged 5.4 cranks don't have center counterweight like the cast 4.6 cranks but unlike forged 4.6 cranks), Ford claims the rods to handle 750HP at the flywheel or surprise 638rw @ 15% DT loss, pistons are 2618 forged Al by Mahle meaning they'll handle much more than the crappy Zollners in the 03/04 Cobras whose skirts yield @ 550rw.
All in all it's not a bad package, I can't wait to rip it out and start all over again.
Good information....Any more specs? Are the injectors and MAF up to the task or does it need to be upgraded.

I wouldn't be surprised, Ford knows what people are going to be doing. They'd be stupid not to overdesign the car.

I am hoping this motor winds up in an SE N/A... If in fact it does, with all the related components, then this is exactly what the Mustang will need to hold off the new Challenger's and Camaros...

Or is it? Anyone know aproximatley what a 6.1L Hemi will do with a blower or Supercharger?

Hey Suds, Crispy, 2L8IWON, what's going on

FWIW, I am Rad Craig's vehicle donor for www.inductionconcepts.com 's Twin 66mm kit for GT500s Look for my OEM shortblock and blower (keeping the heads) on Ebay in the next few mos.

I think you hit the nail on the head. A naturally aspirated version (fingers crossed for a decent OEM intake) of this motor would make a lot of sense, with regard to both financial obligations (won't need emissions recert if they borrow from the '00R correctly) and a decent timeline, for Ford to drop in a high performance (Mach/Boss) SE.
As for supercharged Hemi's I remember hearing about a Procharged 6.1 Chrysler 300C making 700-750HP (not sure if it was flywheel or RW) with a prototype kit from ATI. It ran in the 11s @ almost 120mph. No idea on boost level or if they forged the internals.

Haha, why is anyone surprised? Now show this to the guys that are buying Saleen Extremes.
Just read about some mild mods getting the E to 660rwhp...

That would be what all of us have been longing for, except make mine an aluminum block to save some weight off the front end.

Crispy23c visits SVTPerformance enough to know Fourcam knows his stuff just like I do!

Welcome to the boards guys!

Loosen the suction buddy, you'll be ok

I on the other hand have a hard time believing it. It took the Stang community a while to figure out the recipe to get our Terminators over 500 at the wheels. I think that the GT500 will dyno at around 475-500rwhjp stock and with a pulley prob in the high 500s. That’s just my opinion though.
PS Andy, welcome to the board, this is my favorite site by far.
I don't know if I could . I cant wait to get mine and change all of that to get 638 rwhp .

I recall reading somewhere that due to the modifications which were made to get the hemi to 6.1 in the first place, the compression ratio went way up and the internal tolerances (now this part may be made up by my untechnically savvy memory) were such that forced induction would not be particularly viable, at least on the 6.1.

If I recall correctly, these, along with the stroking, were also the reasons why the 6.1 does not have the multi-displacement feature that the 5.7 hemi has.

Of course, I barely understand the base concepts of most of this, so I could be completely wrong.

I'd love to see that as well. There are a few problems with using the 356 GT Al block in a Mustang (Front eng./rear drive app.). First, the starter bosses are on the wrong side of the block, which can be remedied with machining. Next, unless you're using a dry sump oiling system ($3400 for an Aviad 4 stage dry sump) you're going to need to drill a dipstick hole in the block which requires fabricating a jig to do correctly and a Peterson external wet sump oiling system ala nascar. On top of that is the price of the block itself, retailing @ $2500. While that sounds high at first, you have to remember that it is a full on aluminum race block capable of 2000HP. Similar quality blocks for pushrod motors are $5-10K.
I'm with you though, the SE needs an Al block.

This is quite amazing news. The potential of this engine setup seems to just have begun. Considering how minimal amount of money you would have to spend (respectively) that you would spend for those parts, that is awe inspiring!

Thanks Brad

Dude, are you serious? You still think Saleen's blown 3 valve 4.6 liter can compare to the Shelby's blown 5.4 liter 4 valve? Dude...seriously the Cobra is going to rock the S281E there is really no way around it.

Fourcam, and our other super engine guys, any ballpark estimates on howmuch the engine will cost by itself?
