Default Superchargers - Blocking vacuum line to BPV

Hi Guys,

Have a question around this if anyone has tried it, and wanted to know thoughts around potential issues or ramifications.

My mates who have turbo setups block their vacuum line that runs to the BOV's. This causes the air to run back down the pipe and out the turbo, which creates a fluttering sound that sounds awesome.

We tried this on my HKS SC setup once last night and the sound and effect is exactly the same, it definitely left a big grin on my face!

However, before I decide to continue with this mod, are there any damages this could be causing the supercharger and/or the pulleys?

I understand its slightly different on turbos as they are spinning on a ball bearings, what what about on superchargers?

^ +1 - compressor surge. also, if you take the line off the BPV without capping it you'll have a boost leak.

You bring up an old thread to flame?

This forum is full of immature kids and obviously people like you with too much time on your hands.

If i think it sounds good, who are you to say otherwise?
