Product Description
The GSC Power-Division billet S1 cams for the Mitsubishi Evo 9 are designed for those with a stock turbo all the way to a GT30/50 trim. 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 25-40 WHP (depending on turbo) have been seen by simply bolting the S1 cams in.
Notes:
- Designed for a rev range of 3000-8000 RPMs
- These cams work well on the stock valve springs
- 300-450 WHP camshaft
- Made 100% in the USA
**If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm under head length bolt may be necessary in this case**
