HKS BOV! too loud!!

335iJWC · 10-12-2011, 09:11 AM

Hey guys

i have the ER chargepipe with the HKS BOV and two meth bugs, i think its too loud for my taste. ive been searching and i know there is inserts you can buy for it, do any off them quite it down.

im running meth so cant go back to stock unless i tap the stock pipe or buy an elbow.

ill buy ur charge pipe and bov if price is right ; )

usc335 · 10-12-2011, 09:38 AM

Just remove the insert entirely. That is as quiet as it'll get and will eliminate the high pitch sound.

Cool!! Thanks, ill give this a try tonight!

If it's still too loud then, hook a 1-2 ft piece of hose to the vent of the BOV and point it down to the ground.

That is assuming you have the HKS recirculating insert.

If it's too loud just recirculate it.

I can't even hear my Tial when I shift. It's probably not that loud at all.

Not meant to hijack, but in a similar situation. Running meth with ER and Tial. Don't like the meth blowing off into bay. How can I switch the Tial to recirculate?

Take it out entirely and sent the charge pipe back and get connections for Diverter valves...I just cant understand why people install a bov and also have meth injection.

you can also contact a tial distributor and get the recirculation fitting, it's not terribly expensive and will allow you to run a hose down from the engine bay to vent

Just bought the HKS recirculation fitting $22 shipped

I can answer that one very easily....for me anyway...inexperience.

Actually I am in contact with ER now. Am leaning strongly toward getting a whole new pipe (the longer version this time so I can place the bungs at the elbow area and get rid of the oem rubber elbow) with the BOV connections.

That would save me some $ obviously. Thanks for the info. May look into that.

Where did you buy this from and how do you install it? I am tired of that stupid high pitched chirp from the HKS BOV.

Ant Anthem · 05-04-2012, 09:09 AM

I found them on a few sites but none say if it will work with the one for the 335

Syndicategt · 05-04-2012, 10:40 AM

Trade it in for a TiAL or Synapse BOV

Mike@N54Tuning.com · 05-04-2012, 10:43 AM

Tial is probably the quietest BOV compared to Synapse and Tial and is actually my #1 seller.

Can someone comment on putting the recirculation fitting on the HKS BOV? It essentially turns it into a Diverter Valve correct? Any pros or cons?

Correct. No cons.

Ant Anthem · 05-04-2012, 12:43 PM

Is there any room for adjustments on the blow off valve itself, to remove that annoying chirping sound?

Fred_Boosted · 05-04-2012, 02:34 PM

hmm

I have my HKS BOV with insert also, I can't hear it when I cruise under 3k rpm.

With window up and music on, nothing at all...
