Supercharging Sound Level
Hello guys,
Can anyone recommend possible ways to dampen the sound of a supercharger? I just had one installed and it's a little too loud for my tastes. I even hear the constant hissing sound when I'm idle.
Thanks for any help.

I had this rattle noise at idle with the ECS kit and it was driving me nuts. http://www.kennebell.net/KBWebsite/C.../GearNoise.pdf
I was able to reduce it by turning up the idle to 850 rpm.
I think the optimal solution would be to dampen either supercharger pulley. Hoping an aftermarket solution presents itself.

It's the loudest BOV because it moves a ton of air. It's a bit much for me, as well, but there are some options...
Let me know if I'm on the right track here...

It's the ECS SC. It's a very noticeable upgrade. I gained around 155rwhp. Was hoping for a little more but it could have been other factors like low octane and the weather being 85 degrees.

It's the Tial that you're having an issue with (sound-wise).
There are a few options - one, you can contact Tial and buy the Q bottom-end which is meant for BPV applications and use a filter on it. I'm not sure this will flow sufficiently for our Novi 1500s, but it's an option to pursue.
Or, you could add another BOV to diminish the sound (this was done quite often on the C6 kits).

Yep, I have the kit, as well, as you can see in the signature.

2nd bov doesn't make it quieter, not in my opinion. You can try a stiffer spring but I wouldn't suggest that because it may effect drivability. Swapping to a quieter BOV is probably the best choice.

Others who have done this can certainly chime in, but I'm considering this, myself.
By adding a second BOV, you are halving the amount of air travelling through one of the valves. The sound you're hearing is caused by the air moving through the valve, so you would be halving the noise from both idle sucking and blowing off.

The best bet is the Tial 50 Q bottom end (cheap and plug-n-play) plus a filter - so long as it moves enough air! Please check that first, though - nothing worse than causing compressor surge because of lack of flow, etc.
You can also run an adapter from that flange to another type of BOV brand (flange adapter required of course).

My apologies - my reference to the 'quieter' Tial 50 Q before was meant to be the QR as pointed out above.

It just moves a ton of air... I'm with you, though, Sometimes it's just a little much for driving around.

I was close to purchasing the Edelbrock supercharger,but after seeing the installation instructions,i decided to see a&a but it was pretty much like the edelbrock,too much work,1 of the kits you have to remove the abs,the other disconnecting the steering rack,so im worrying about the installation here in Kuwait,rattling of some sort/problems later on.
The ecs kit seems easier,it says a 1 day installation

Yours (the standard with the kit that we have) is the Tial 50 Q:
