It is not likely that you will see a supercharged SRT in the near future. The stock crank pulley is too small in diameter to drive a supercharger off of an there is not enough room between the power steering rack and the stock crank pulley to add a 10 rib system. Looks like twin turbos it is! I have done some experimenting with a SRT and so far with minor engine mods I have made 534 rwhp and 525 rwtq. The mods are ported heads, headers, exhaust, and a cam that is very similar to a 97 cam. I'm going to try a couple of other cams soon and think we should see near 600 rwhp with the right combination.
