|Adam Montague, chief spanker over at Spankin’ Time Motorsports in San Bernardino, CA (www.spankintime.com) has built some pretty amazing late model Challengers, Chargers and Jeeps. His own ride is a built 6.1 Hemi stock-block ’09 Challenger that, thanks to a Kenne Bell 4.2L twin-screw billet supercharger, makes 931 horsepower at the wheels. Running its full porker weight of 4610 lbs., the Challenger turns 9.97 @ 130 MPH in the quarter. One of his customers runs a KB-blown 5.7 Hemi Charger that also burns up the strip in the mid-9s.
We ran some Kenne Bell blower install highlights in our February issue, and we’ll show you a couple more here. We’re also adding here the dyno charts that compare the stock vs. supercharged versions of the Gen III 5.7 and 6.1 Hemis. You can see a lot more tech info on Kenne Bell by checking out their website: www.kennebell.net.
