those of you with a paxton,vortec,procharger or any other gear type charger how noisey are they comparted the the kenny bell,whipple,salean, and so on.the full throttle howl is fine but what about noise at cruising speed?also,about what rpm do they start to make good boost on a 8 lb kit?

 

They whine a good bit under most driving but it's nothing that bothers most people. Under boost you don't hear them unlike a roots or screw-type. Highway cruising the whine is hardly noticiable. Will get you some funny looks in city traffic though.

 

I have a Paxton Novi 2k and the noise level is said to one of the quietest of the gear driven centris. It is noticable at a 650 rpm idle as a low whistle, and gets slightly louder at 850 - 1,000. Above that it is not audible at all, as the engine and exhaust sounds take over.
I would not let noise level be the major factor in my choice. Everyone seems to learn to love whatever they have.

 

Truely I wish my Procharger was a bit quieter with the gear noise, I love the whistle that it makes. The gear noise is only heard at low idle rpms. Once you're on the gas the gear noise goes away. What my buddies and I like is the sound on the highway, much like a jet engine with that slight whistle and the exhaust sounds. A while back I was at the dyno shop and one of the guys took me out for lunch in his Chevy truck with a magnacharger and I really liked the whine of that blower also. Personally I don't think any blower sounds bad, just bad a$$.

Hell yeah I second that, I drove into Chicago 2 weeks ago and on the way back it was kinda (considering I have the Roush O/R exhaust) quiet doing about 70 on cruise and I actually got a headache from the whistling sound from the intake (I have the Roush Supercharger) but its cool almost sounds like an airplane. Other than that I like the sound from my blower sounds like a screaming Banshee.
