I recently went on the Hellionpowersystems.com website and they recently launched a new 500Rwhp Twin Turbo Kit for the Challenger SRT8 and the nice thing about it.The Kit fits all 300C,CHARGER,MAGNUM SRT8 Models.
the price is about $8,000 which is kinda high but considering everything else on the cars were stock to my knowledge the power gains are good.
I'm wondering if they'll come up with a TT kit for the 5th gen

BTW all this talk about garage's compound boosted snake makes me seriosly consider getting a 03-04 cobra just for that purpose
