I am after instant gratification right now. I can always get a pricier engine later on. Plus, there are several SRT-6's. What are there--like 4 V8 Crossfires in the world? I still would think that the mod capability for the 8 is better than the 6. I don't see why it couldn't be supercharger later. As long as it is an AMG. I am courious though, for someone who is good at calculating things, how much horsepower can be had before one must replace the stock N/A transmission?
