Well, it IS possible if the rumor I have heard is indeed true :
Wikipedia says :
SL 320 with a M112 3.2 L 18-valve SOHC V6 (224 PS (165 kW; 221 hp) at 5600 rpm
( that's 6 more hp than the Crossfire's 215, I believe the SL320 had the 74mm TB )
But I have also heard that the true HP of a stock N/A Crossfire is around 240.
I have never seen any facts to back that up, however if true, then my mods might well place it in the 260-270 HP range.
I'm just too frugal ( mrmiata's word for cheap ) to drive 100 miles one way to find a dyno and know for sure.
