The Kenne Bell kit required a dedicated lower intake assembly to secure the twin-screw supercharger to the LS3/L99 cylinder heads. The three-piece design not only provided exceptional port flow, but (more importantly) housed the ultra-efficient air-to-water intercooler assembly. Run as a self-contained system (including its own pump and front-mounted heat exchanger), the intercooler is a serious weapon in the fight against detonation.
Actually, the intercooler improves the safe power output by significantly reducing the air intake charge temperature. Since heat is a natural by-product of compression, the intercooler is called upon to reduce this unwanted heat. Running just nine psi, the efficient twin-screw design provides very little increase in charge temperature, but the intercooler has been designed and sized for future (read higher) boost levels.
Helping to further keep things cool is a compressor bypass valve. The bypass valve is used to recirculate the air from under the supercharger back to the inlet. This helps both lower the inlet charge temperature and reduce pumping losses under cruise conditions.
Additional features on the new Kenne Bell Camaro kit include a fuel system upgrade consisting of 60 psi injectors housed in an aluminum fuel rail and fed by a Kenne Bell Boost-a-Pump. Like the MAF, the larger injectors required dedicated programming.
When everything is said and done, you have a complete system that will increase the power output of an LS3 Camaro SS from 376 rwhp and 374 lb-ft of torque to 553 rwhp and 505 lb-ft of torque at just 9 psi on 91 octane fuel.
The peak power numbers are nice, but so too is the fact that this system provides a big block-like torque curve, bettering 450 lb-ft from 2,500-6,500 rpm.
