Just looking for an idea where to run my mighty mouse catch can on a Whipple. I have one side coming off the driver side valve cover and I assume it would go back in where the intake tube is pre throttle body just like the Whipple line is ran?

 

It would continue to wherever that driver side hose goes to. The passenger side is inlet air, driver side is exhaust to the intake.

 

With this thread mentioned might mouse catch can, whats people opinions on thinking they are a must for boosted applications? I think the obvious answer is yes, because of their design but dang that much money for a can.

 

I personally think that style can is not a good fit for boosted applications. The sealed cans dont flow enough on boosted stuff to adequately vent crankcase pressure. It has its drawbacks but for the purpose of venting crankcase pressure under power and not injesting oil I never use a recirculated can and just use a vented one.

 

I just drilled out my oil fill cap and glued a filter on it.
