This is a gentleman’s muscle car. Starting with a stock Hemi SRT Challenger, we proceeded to add a supercharger and added some paint touches. This car was a lot of fun to drive, and got lots of looks. If you look closely, you can see the green accent stripe around the R/T style stripes. Although subtle, that really added a lot to the car’s appeal
Before installing the supercharger, we put the car on the dyno. It produced 342 HP and 337 lbs/ft of torque as delivered from Dodge. After adding the Kenne Bell supercharger kit, these numbers jumped to 515 HP and 472 lbs/ft of torque. That’s a big increase, and it really woke the car up – not that it was a slouch before.
The Kenne Bell kit included a 17V Boost-a-Pump (BAP)to enhance the flow rate of the stock fuel pump, while the factory injectors were replaced by a set flowing 50 lbs/hr. According to Kenne Bell, the fuel system upgrades to the Hemi will support up to 650 rwhp. Additional power can be had with a 20V Competition BAP and 75-80 lbs/hr injectors.
This was the first prototype of the Mr. Norm Supercharged cars. It was very successful, and we ended up building a lot of supercharged cars over the years
