Does any one of you own a turbocharged GT? Or you just dreaming of owning one some day?
I own a 06 turbo GT and IT owns every other forced induction 05+ Mustang that it has ever been up against.

When I went S/C about 5 months ago, there was not a lot of talk about turbos...now there are more vendors, more choices, prices for single are in line with some S/Cs. Had all this new info been available (maybe I just wasn't paying sufficient attention), I would have at least looked into turboing a lot closer.
Since then as a newbie, I have learned that great dyno numbers are only part of the ET equation. Traction and gearing are others.

To say the least, I am well informed about turbo's, KB set speed records with their own KB turbo in the 90's with a Regal. But when you all u turbo idiots say that turbo's are the superior bolt on for performance, then I say U don't know ****. If turbo's were the superior FI system then Dragsters would be using them to set the records instead of SC"S that they own or owned. While turbos may be your choice SC's are far less complicated to install and tune with the same and even better performance than turbos. No, I am not stuck on a product pushing company trying to sell me something I did my homework. SC's came out on top for me.

Have you (or anyone for that matter) took the time to think why 90% of car manufacturers use turbos on there cars? the rest are using a compressor type or whipple supercharger or whatever you wanna call it such as Mercedes and Ford. That pretty much says it all for me, If i'm not going turbo it'll be KB or Saleen.
Another thing, there is a reason why a turboed car will (mostly) beat a similarly equipped supercharged one. a supercharger might provide boost sooner, but once you have a turbo spoolin it will hit full boost in midrange and stay there no matter what your engine rpm is, even when upshifting the rpm will drop from 6k to 4-4.5k and the engine will still find full boost there and continue to pull hard with no hesitation!! that's why every single video of a turbo Stang against a supercharged one ends up with the turbo winning!!

The only reason manufacturers use turbos more often than superchargers is simply because they are cheaper, when money is not an issue, ask Mercedes why they use superchargers (Whipple) on their exotic AMG series and turbos on the C class. Also as someone pointed out before, ask yourself why top fuel dragsters use superchargers instead of turbos.
If you want a big boost in performance for race purposes probably either way of force induction will do the trick, but for the street, only Twin Screw or roots will give you instant acceleration and full boost from 2000 rpm and the feeling of a big block under the hood, on the street you live under 4000rpm that is where the turbo or centrifugal begins to make power. The choice is very obvious to me, Whipple or KB all the way.

I would probably choose KB too, i prefer that big block power, although the noise they make is annoying for my taste while some people love it.
Note: Of all FI companies i checked, turbo kits are always more expensive than blowers!! except for the KB about the same price.

Are you telling me that the (Mercedes 600S, SL65, Porsche911Turbo, Bugatti Veyron) use turbos because turbos are cheaper?

Erm sorry but all high end cars use turbos. A turbo is much costlier than a s/c set-up because all the manual labor and piping that is incurred. Surely a pos kit will be significantly cheap. But if you want a good ball bearing turbo, nice digital waste gate with boost controller. Good blow off valve and what not they usually go pretty expensive. LOL a turbo at 4k rpm? Sorry but on our cars a good turbo set-up is already spooled up by 2.3k rpm. And during shifts you dont loose much of the power like you do on a s/c car. Now for a second just leave out top fuel dragsters taking into consideration NON OF US DRIVE ONE TO WORK EVERY DAY. That said all the fastest street cars are turbo. Just go into the 03-04 cobra section and check how many people have changed to a turbo set-up whY??????

Everyone keeps bringing up dragsters as an example of supercharger superiority. Doesn’t anyone know that superchargers are mandated by NHRA? Turbo setups were tried many years ago and had some very promising cars but NHRA decided it would be almost impossible to make fair and enforceable rules for turbo cars, they also didn’t like the looks of all the piping involved, in what is now called top fuel class. This is the reason for superchargers only in top fuel not because they are better than turbo’s.
As I stated before each type has its good points and this debating could go on forever and never change anybodies opinion. For everyone trying to decide which way to go just be sure to do your research and decide how you like to drive and what power levels you are looking for as part of your choice.

By the end of this month/beginning of next i will have purchased and installed my turbo kit. I will provide a detailed report on all points. Also we can compare price tags with lets say.......a full whipple install. I will also post some vid of me racing my buddies KB 06 GT.

its simple, TURBOS>superchargers...the very best cars use turbos, why do u think when John Hennessey made the Venom Viper he used TT's rather than a supercharger, or when Lengenfelter made the C6 corvette with TT's, or when Heffner Performance made the TT Ford GT w/ nearly twice as much HP as the supercharged GT and when he made the TT Lambo Gallardo, not to mention Steve Saleen's S7 TT...why didnt he use a supercharger on that like he used on the mustang? maybe the top performance vehicle in my mind, the Audi LeMans TT...the list goes on and on, Koennegsegg, Ferarri, etc...they dont use turbos b/c they're cheaper, they use them b/c they are more efficient...btw, my friends TT 2002 GT(kit from Turbochargedpower.com) whooped the $hit out of a 03 KB Cobra...he's running 13 psi and is above 520 RWHP) and people shut up if u havent driven or rode in an up-to-date turboed car...modern ball bearing turbos, produce no lag whatsoever...TRUST ME
