The point, was that this was a callout (by a built evo) gone bad. And, that with the right setup, RWD>AWD....
From what I understand, EVO guy know what the Cobra had, and what he ran. He just thought things would work out different on the street.
I'm guessing staying with the stock cams was a dollar/per hp deal. 2-3K for some custom grind turbo cams would probably net him an extra 100 horsepower or so(best guess). I've seen similar setups at around 20 psi see gains of around 100 hp by going with turbo cams over the stockers. And in most other applications custom grind cams are good for 30-40 hp. Though they are blower cams, they work pretty well with turbo setups. It's an expensive mod for the money for these DOHC motors, and one of the last mods you'll see on the to do list.
I don't know what the EVO runs, but its a 700 whp car...
