I've been getting a bit worried at hearing of various reports and possibilities for a GTHO, regarding super/turbocharging.
I'm not a hater of forced induction (done right, as in XR6T, Nissan GTR, etc they can be fabulous), but I do cringe a bit at the thought of a GTHO resorting to such measures.
I believe a GTHO should, nay, MUST, produce brute horsepower the "pure" way, using capacity and revs. My ideal HO motor would be the current 5.4 litre Boss tuned and strengthened to rev to at least 7000 RPM or even 7500RPM. Wouldn't that sound glorious?
I would prefer it stay N/A but the reality is that foced induction is a cheap way to make alot of horsepower and manufacturers are in the business to make money. If they could make a 5.4 with lets say 350kw and 600nm N/A, then I say go for it. I want Ford to release a beast with this amount of power, but If it can't be done naturally aspirated then I don't think they should not proceed just because they have to use forced induction.

i look at it this way............
IF the GTHO does come out Naturally Aspirated.. people can just bolt a supercharger on and already you got a GTHO-eater, then the fastest sedan in the world wouldn't seem as fast anymore.
I would prefer it to be forced-fed straight from the factory because like cobra said, its the cheaper alternative (instead of going 7.0Lt V10, etc) and also.. you can't go past forced induction these days for performance.
edit: I also want to see quad exhausts (2 each side).. and also flared arches (wide-body design)... 19 inch wheels a must!!
This isn't the 60's, manufacturers can't produce lumpy growling thirsty beasts any more. Forced induction is the only answer, for a number of reasons:
(1) There is no way that a highly tuned N/A Boss would be streetable for everyday driving, and in this market segment, there has to be plenty of refinement as well as outright grunt
(2) A highly tuned N/A Boss would never pass ADR & emissions regulations
(3) Can you seriously see Ford offering a 3 year warranty on an "at the limit" N/A engine?
(4) A larger capacity engine (think V10) will not fit into BA engine bay, let alone survive the beancounters for R&D expenses!
(5) A low-mid boosted engine will provide a superior torque curve, more refined power delivery, arguably better economy, and less mechanical stress, than a N/A engine with the same power/torque figures.
(6) You can't beat forced induction for easy power gains and a value-for-money upgrade path!

Clicky clicky here for previous ride! I still miss her!
Now i don't know why some people think this is the easy way out, or it's the cheap way out... by no means this is a "cheap" way around making horse power.
Just ask David Flint and the engineers at FPV regarding costs for validating, evaluating and developing such an engine. Obviously these costs would follow onto other components of the car, such as gearbox durability, as force fed engines characteristicly produce power/torque lower in the rev range, so gearbox validation and testing would have to be carried out on such a configuration.
And as Sparkles has already said, there would undoubtably be benefits in economy, drivability etc...
If it was good enough for mad max, it's good enough for any of us!
Falcon Killer (if you believe what Ford Service Departments have to say about me)
AU II XR6 - October 2001 ~ December 2002 - RIP
BA XR6 - December 2002 ~ Soon to disappear if Ford CRC can't fix it....
45,000km service coming up - and i'll be asking for a sizable list of fixes:
* Gearbox (3rd time)
* Steering click (5th time)
* Brake Shudder (2nd time, and has the applied "Fix")
i belive becuase Ford have made such a ripper in the XR6T that the car buying public would accept a supercharged GTHO in the belief it WILL be just as good as a xr6T. The XR6 has begun a psyche change in australians car buying minds i believe........
Also, to get the required power fit for a GTHO, forced induction is the way to go in terms of what Jem and Mr. Sparkle said
