Centri sleeper

[PC_GUARD]

I am purchasing a G3 kit. I have zero experience with centri's and would prefer to keep it quiet as possible. I know most everyone just vents the bov to atmosphere, is there/has anyone done anything else to squash the blow off noise?

Im just trying to get my complete parts list together.

You could put some sorta muffler/silencer on it to keep it quiet. Would be very interesting.

You can buy a "suppressor" that's not an NFA item but listed as a "fuel filter" with very common thread patterns. Just don't ever put it on a firearm and you won't go to jail

I just tell people I have a squeaky belt with my G3.

A centri is not the way to go if you want to keep the car quite. Put in the remarks when ordering to have them put the standard gears in it.

That given but I wasnt sure if anyone had managed to quiet down the bov. Like a factory turbo car, you dont hear the bov.

I'll live with it either way

The BOV is used differently in a centri application vs turbo.

Since the centri is always under load and spinning because its connected to the accessory drive belt, that air being generated has to go somewhere because the engine cannot consume it all at idle and part throttle. In the centri application, the BOV is always open under idle and part throttle so it is ALWAYS noisy. That was my single biggest complaint of the Paxton kit I had on my 2014 Mustang.

The only time the BOV is closed is when you WOT ... as soon as you lift, it's open again.

procharger kits come with a filter on the bov and it quiets it way down

Ask @Brevin@ESS about it

My ProCharger P1X Stage II came with a BOV filter/muffler as standard on my set up. Would not run without it. Very quiet. Can't tell it's boosted.

I don't know how anyone could stand a noisy BOV for everyday driving.

Like they say, if it's too loud then your probably to old!!

On some of our other kits we use a bypass valve that recirculates the air back Into the intake system. It’s virtually silent. A custom boss/adapter could be machined to fit our v-band flange on the intercooler and you could run the vortech bypass instead and plumb it back into the intake tube. This is intended for lower boost applications, but could be something to look into.

Actually this could be your best bet. Haven’t done any testing with this but it’s recirculating and should be much quieter. It uses the same v-band connection and would be bolt on with our intercooler. Would just need to route a recirculation hose back to the intake.

Thats exactly what I was looking for. Thanks Brevin!
