You never add weight unless you HAVE to.


You're better off being at minimum weight than being over with the weight where you 'want' it. The bottom line is you don't 'want' weight. Being at minimum weight is a good thing. Tires last longer and you have less car / sqin of contact patch. Brakes last longer and have less heating issues. It's easier on the drivetrain and engine.

(Adding weight where you want it is only applicable when you are below the minimum weight and need to ballast up.

I'd go with restricting airflow before I add a manual fan. It's rotating mass. Rotating mass is bad.. it just adds more stress to the engine.

A cam change might be your best bet. Something a less peaky with a broader power band would be ideal.
