LT5 Belt Tensioner + Billet Adapter Bracket
As you may be finding out, belt slip on a modified LT4 can still occur even when using all of the best parts available (ZPE Griptec upper pulley, Larger lower pulley, and the Gates HD Green Belts) This is exactly the issue I had, even after replacing my upper pulley and a fresh green belt. With only 770rwhp, I was still seeing alot of boost drop and belt slip on my HPT datalogs.
The solution? We have two depending on your power level.
The most cost effective solution is upgrading to the GM LT5 tensioner.
Why? Because the the OEM LT5 tensioner provides approx. 30% more belt tension and has approx. 12% more belt length take-up. This helps tremendously with belt slip, on higher HP builds.
Keep in mind, despite the LT5 only making 100hp more than the LT4, GM realized even that small of a bump in HP/TQ not only required 30% more belt tension, but it required an 11-rib belt which also provided 37% more belt surface area to prevent slipping. That context alone should help us understand why so many LT4 owners with even light mods are already experiencing belt slip with the LT4’s 8-rib system.
Luckily, the solution is pretty straight foward, and one that has already passed through the brain trust with our friends at Too High PSI. They have already created the perfect billet adapter bracket for the Camaro/CTSV LT1/LT4 users, allowing us to bolt the OEM LT5 Tensioner with no fuss, onto a stronger than OEM bracket. The Too High PSI Supercharger Belt Tensioner Bracket is not only a work of art, but it ensures your supercharger maintains full boost throughout your entire run - giving you the competitive edge you need, to keep all that power where it belongs… the pavement.
We think this is a great option for builds from 650-800rwhp.
Making more power than that? Then I suggest checking out our complete 10-rib upgrade package for those making 800rwhp or more found HERE.
