Has anyone checked out the article in the March C/D magazine?
Hennessey bolted on a turbo onto the SRT8 Grand Cherokee. 0-60 in 3.7 seconds. 1/4 mile in 12.2. Price of admission: $76K.
Bad news - they fried the transmission during testing. Also the turbo is located underneath the engine - that should take all the fun out of driving through puddles.
No article posted to the caranddriver website that I could link to...
