View Full Version : challenger w/twin turbo

saw recent horsepower show where they put twin turbo setup on new challenger. custom exhaust too. made 120hp more with 4lbs boost. said they had to swap pistons out so they could lower compression down from 10.75 if they really wanted to step up the boost. than they also showed a jeep with a 7L motor that made 600hp? would love to see specs on that motor. i bet the turbo setup is $5K plus $1k for exhaust. the NA motor has a stroker kit plus better heads and cam so its probably close to 6k also. not sure which motor would be more fun to drive.

On a side note I think it's funny the Jeep SRT-8 is faster then the Challenger SRT-8 stock for stock....
