[QUOTE="Kenne Bell, post: 16338208, member: 13389"] Justin, I believe you are confusing the undersized 2.65 you use in your kits with the KB Liquid Cooled Patented 3.2, 3.6, 4.2, 4.7 and 4.9 displacement superchargers. If you are going to continue to hype without data, you should know that: 1). KB superchargers do not need to be kept under 30 psi and preferably in the 20's 2). KB superchargers can run 30-40 psi We run 35-38 psi on Mark Meiering's 1652RWHP Record Holding 6 second Shelby GT500 and 32 psi on JLP's 1500HP 5.0. Have you ever measured the temps on our 3L and 4L superchargers? 3). Too much rotor deflection? You can measure this? I own the company and am not aware of any "rotor deflection" that causes any issues. Now to your comments about the 2.65. "No RPM limit on the 2650?" Really? Enough of this B.S. When tested, the 2.65R on our supercharger dyno (at a much lower 23,000 RPM and 22 psi), we were forced to lower the oil level 50%. And even then it burned the paint off the front cover and destroyed the drive. The 2.65 Shelby kit supercharger completely melted and dissolved the front plastic coupler at the same 22 psi. The remnants destroyed all the bearing and scuffed the abradable rotors and internal case. Air charge temps were 380 degrees or a big 55 degrees hotter than the 3.6 at the same boost. This is data from our own dedicated supercharger dyno. You may want to consider purchasing a supercharger dyno as testing on a chassis dyno does not in any way provide all the necessary data for supercharger development.
