Vortech 6-Rib Supercharger Pulleys are machined from 6061 T-6, hard anodized aluminum with the proper profile to maximize surface contact area for precise fit. Each pulley is built to SAE standards.
To adjust boost levels on Vortec supercharged VQ35's, the simplest way to do so is by swapping to a different size pulley. Smaller diameter pulleys are used to spin the supercharger faster and raise boost levels while larger diameter pulleys slow the supercharger lowering boost levels.
**When changing pulleys a re-tune is required to compensate for the additional boost produced by the supercharger. Faliure to do so will force the car to run lean resulting in catastrophic faliure. A different size belt may be required based on the selected pulley diameter
Use the options below to select the correct size for your application.
