GSC Power-Division Camshafts R2 Grind

GSC worked with English Racing on this camshaft to offer the 2.2-2.4 lower reving engines with MIVEC control a camshaft that would allow for more air volume in the cylinder to help fill the larger displacement engines and make more midrange and top end power. The 7009R2 is designed to rev between 4000-8500 rpms and should be used with a stroked engine or added displacement engine. The peak lift of 12.1mm intake and 11.9mm exhaust will require upgraded valve springs and a titanium retainer with special attention to seal to retainer clearance.

With the lift of this camshaft, it is suggested to only use the 5041/5040 Ti retainer and spring kits due to valve seal to retainer clearance. The 5041 can be used to 40+psi and the 5040 to 32psi on the R2 profile at 8500rpms without float or flutter issues. This camshaft will work fine on the OEM Rocker Arm and the Zero-tick lifter or with the OEM lifter.
