The S1 cams are designed for those with the stock turbo or 300-400whp range. These cams will not sacrifice any bottom end loss over stock cams; nothing but gains and will promote faster spooling of the upgraded turbos. Gains of 30-55whp (depending on Turbo) have been seen by simply bolting the S1 cams in. Designed for a rev range of 3000-8000rpms, these cams work well on the stock valve springs. 300-450whp camshaft. Idle is slightly rougher than stock.

The S2 cams are designed for those with more power in mind or a larger turbo. No low end power is lost vs the stock cams when used with the larger turbos. The S2 cams will show gains of 50-70whp over the stock cams and in some cases more in the higher RPMS. Great for 2.0L engines revving to 9000rpms or for Stroker motors revving to 8000rpms. The S2 Cams are suggest to run on our upgraded Beehive valve spring replacement or can be run at the stock revlimit and factory boost on the stock spring. Designed for a rev range of 4000-9000 RPMS(2.0L or 3000-8000 2.2L+), 400-700whp applications. S2 cams can run on Factory ECU with custom flashing.
