An SRT had a Vortech supercharger added to it- 640 hp@crank, 525 hp@rear wheels.

Very cool stuff coming out now for us.

 

Cant wait till the vortech s/c comes out for the r/t. Lemme know if you guys hear anything

 

is this correct? the specs on the hurst challenger, which basically uses the same supercharger, says its got 572 hp and 482 hp at the rear wheels. obviously i hope this video is correct but im finding diff numbers online

 

Different Dyno, different numbers - even on the same car.
Compare cars on the same dyno and the "spread" will be more accurate.
