Review on Competition Cams 7138 Keyway Adjustable by Adrian Olivares
Useless Adjustable Keyway for Engine
Based on my observations, this product is a complete disappointment .The installation was difficult, and even after adjusting the keyway, there was no significant change in performance. The only good thing I can say about it is that it looks nice on my engine. However, the lack of results outweighs any aesthetic appeal..
Pros
- Allows for precise timing adjustments to improve engine performance.
Cons
- Requires technical knowledge and skill to install correctly.
