Kenne Bell S/C Whine

which KB are you talking about? Cobra KB 2.2L is loud; has a higher pitch whine/scream than the Eaton.

2.2L for the 2Vs are loud as well

1.7L for the 2Vs aren't as loud. Mine was noticeable until I added o/r x-pipe and longtubes. The exhaust now drowns it out.
 
:scratch: You can barely here a KB 1.7 with 9#. The only time i can here it is when it is coming down from rpm. it makes a little whislting sound. Not loud at all. Especially with LT's and exhaust you will never here it.
