For the two or three folks on the board who might genuinely be interested, I have started the process of installing twin turos on my 2010 GT500.
If you will recall, I had previously owned a 10-second KenneBell 2007 GT500 which I took back to stock before trading it in on the 2010. It had been my original intention to simply transfer the KenneBell, coilovers and other goodies over to the new car.
Well, after much debate and realizing that I would have to make some significant modifications to the stuff I had to make it fit correctly on the 2010, I elected to instead sell the stuff I had taken off the 2007 and go a different route in my quest for better performance.
After consulting with several people with much more knowledge and considerably more experience than I have, I have elected to take the turbo plunge. Not only are turbos an efficient means of boosting power, they could also be installed without making any changes to the car at all. (i.e. no hood notching, no special k-members, no relocation of parts, etc.)
The system I have elected to go with is the Hellion "Hellraiser" system for the GT500. This as a compound boost setup that utilizes (in the kit I went with initially) twin 61mm Turbonetics turbos pushing air through the stock Eaton blower. This setup can be upgraded to two 68mm turbos down the road if I desire more power, but considering that this is my first foray in the world of exhaust driven boost, I figured going with the most basic setup will be more than capable of getting the car to the power levels I was looking for on pump gas and the factory powertrain.
Obviously, one of the factors in making this change was being able to do it with little or no out-of-pocket expense greater than what I was able to sell my other stuff for. I am pleased to say that the mission was accomplished with a little help from some friends and EBay.
I am hoping to make in the neighborhood of around 700-750rwhp on pump gas with this kit in place, but as long as it makes at least as much as I was making on 93 octane pump gas with the KB (~650rwhp), I will certainly be happy. The kit is scheduled to be shipped a week from Monday, and I hope to have everything installed and tuned by the end of October. If that is the case, I hope to get a few runs in with the new setup before Beech Bend closes for the season.
Here are some pics of the kit I have gone with installed on a 2008 GT500:
