The Z33 application does not require a high RPM cam profile since the engine design is suited to 6000 RPM so with the camshafts alone good gains are seen at 4000 RPM with ample power all the way to redline. The PONCAMS exceeds performance in the overall power band range without compromising smooth idle with these easy to install camshafts. The result is amazing street and sport performance as it is proven that Tomei Powered tests all designs on their in-house engine Dyno which reflects on the superb power and drivability for the suited. Response is now more sensitive and will give your NA feel more fun with gear changes and throttle response. With the engine now boasting the sportier sound which can be further enhanced with the upgrade of the exhaust system. We can recommend the camshaft upgrade benefits from the performance results we have seen in our Z Race car from the events we race in. We also now include the camshaft upgrades in our rebuild menus as well.
