Description
#1 SELLING SUPERCHARGER KIT
Since 1996, our most popular 2.1 Supercharger Kit and the #1 choice of Mustang 4.6 owners. It increases stock RWHP a whopping 65-107% (160-262H) with ease. And there’s another +30HP in our wide range of dyno tested inlet system upgrades. For the higher HP applications (up to 1000HP) we offer the 2.6, 2.8, 3.2Mammoth Kits. Check out Ford Tech ‘96-’04 Mustangs for Tuning Tips, FAQ’s, Tech Info and Dyno Tests. (CLICK HERE).
Note: ’96-’04 HP & Torque at other boost levels will be approximately the same as ’99-’04 if late Pl heads are used.
Note: For consistency and to avoid confusion, dyno tests were all run at 11:1 AF ratio and 23 degrees timing. See Tech Tips for more details.

In 1991, Kenne Bell, was first to pioneer the Twin Screw concept on Fords. Those features originally promoted in 1991.
1. Quiet operation.
2. Self contained oil system.
3. Full instant no lag boost (HP and torque) at any rpm.
4. Lower parasitic loss.
5. Cooler air charge temperature.
Further proof of the Twin Screw’s efficiency superiority are the hundreds of Eaton/Roots supercharged Ford Lightning, Cobra and Shelby GT500 owners that have upgraded to the Kenne Bell. All have experienced big power gains at any engine rpm or vehicle speed. Ask any of these owners if they think Kenne Bell superchargers only make great power and torque in the low and mid range.
Given that history of success, it was just a matter of time before we introduced the ultimate intercooled and non intercooled kits for the ’96 up 4.6 Mustang GT. And it’s calibrated in house by Kenne Bell programmers. As with all our kits, we’ve thoroughly dyno tested it at varying boost levels and with other Kenne Bell product options. All major kit components are pre-assembled, sealed and tested. It’s ready to bolt on. Only the best and most efficient components are used – bar and plate intercooler, Dual heat exchanger, billet Kenne Bell Twin Screw supercharger, billet bypass valve etc.
Performance? This supercharger makes maximum power and torque because of it’s 90% efficiency and lower parasitic loss – at any rpm. At either 9 or 14 psi it produces more power than an ’03 Cobra. It’s what you’d expect from Kenne Bell – an abundance of smooth, quiet, brutal power in any gear at any rpm from 1500 to redline.
