Looking at Vibrant 3" velocity stack adapter - Was wondering if adding the velocity adapter and running bellmouth filter worth anything for NA car with built motor running on corn.

 

We did a test of these on my car actually. Using a 3.5" intake the bellmouth actually made a tiny bit less power in a few spots vs a normal filter. This was a 6in bellmouth with a vibrant filter compared to a regular K&N filter. Most filters nowadays seem to have an integrated bellmouth already.

 

thanks for sharing. I currently have 2.75 intake pipe to a filter. Was trying to see if adapting these velocity adapter may help. But given i don't have a straight shot to the throttle body, it may be useless.
