how does a Pete Jackson "noisy" gear drive sound?

like the whine of a roots blower??

i once had a convertor cover that was scraping the convertor and it had that turbo pitch sound and i liked it a lot.

okay forget it, i did a search AFTER i posted this question (smart huh?)

Too much gear sound and bad harmonics. ill pass!

sorry for wasting your time.

happy x-mas

The noisey drive is very loud. Sounds likes rocks getting crushed. The quiet is a much nicer sound, still plenty loud enough. In all honesty neither one sound like a blower.

I have been running a Pete Jackson "NOISY" in my small block since Feb of this year and to be honest it isn't as noisy as alot of people complain about (although I did get stopped by Cobb Counties finest for it, no ticket just curious). I have had alot of people think and ask if I had a blower under my hood (I have a 4" cowl hood).
CFUNK has a video from when we were at the track and you can hear it then.

I am in the process of putting together a 350 and I have the double roller from my old engine and I came apun a dynadrive gear drive I am debating which to use on the car.

What are the advantages/disadvantages of both and longevity as this will be my daily driver.
