Cam + maggy 2650 and supporting mods is fine for road racing/track work. Just don’t try to add a pulley to increase the boost. More boost = more heat which will decrease reliability and consistency when racing. The marginal gain is not worth the trade off. Making the engine more efficient (better supercharger, headers, less restrictive intake, cam with better fuel lobe) will give you plenty of power without affecting your ability to track it.
