No change in turbo sound at all it sounds the same as stock just goes like hell.

 

That is the only thing this beast is missing, would love to hear it.

 

Put different exhaust (louder) to hear turbo whistle

 

An open intake with a filter would allow you to hear it but it wouldn't do well in offroad conditions.

 

add a microphone onto the ducting to the intake, and pipe the sound through your speakers. (Believe or not, have seen folks do this on their turbo cars)

 

Ford plays v8 sounds thru their v6 f150s radios.... gayyyy

 

All I hear is turbo whistle from intake I put on mine.

 

Put a turbo xs blow off on atleast people would know you mean Business lol

Cody,

What intake did you go with? I would love to hear a little noise like a diesel truck . Lol not doing a bov, then it would be a maverick ricer

 

I just installed a BOV on mine. It serves a purpose.....doesn't mean ricer!

 

Turbo rotax with bov sounds badass 4 cyl ricer with bov not good !!!!!

Ive got it installed....it wont pop off just revving the engine in neutral.....makes me wonder if I got the spring a little heavy. It shows on Tial's website..... 16-19in-hg gets plain spring, and 13-15 gets the white spring. I have about 16-17 at idle full operating temp, and closer to 15-16 when cold.

Guess Ill wait and see what happens once I get on 4 wheels again.....waiting on halo locker to show up!

 

Mine barely blows off in neutral there's
Not a not a lot of boost without a load

Drop it into low on your favorite trail and you should be able to hear it.

I was driving around dunes in high and could barely hear it, took my 6 yr old daughter out for a ride and put it in low gear, all i could hear was the turbo.

I know sand is a lot of load and the lower gearing rev's higher but it was still kinda cool

 

Guess Ill wait till she's drivable again and see how it reacts!

 

Does anybody have a part number for a 2015 mav xds turbo blow out valve and where can i get it?

 

There is no stock valve.....I added one to mine. You have to do it all on your own.

 

They say it's better on the turbo and you get quicker throttle response Just think the turbo spinning 100000 rpms Boosting then when the tb closes all that boost pressure has nowhere to go. So it tries to slow down the turbo thats spinning that 100000 rpms to 0 rpms. It can't be good for it. But I think at stock boost (5psi )it's fine it's just when you get a reflash (12psi) you mite want to get one

I would think if it was really needed either EVO or MrRPM would have had one on their turbo Mav but I don't believe they have or at least don't mention it

in their advertisements of stage 1 2 3 and 4's.

 

From Garrett Turbo:

The layout of the turbocharger in a given application is critical to a properly performing system. Intake and exhaust plumbing is often driven primarily by packaging constraints. We will explore exhaust manifolds in more detail in subsequent tutorials; however, it is important to understand the need for a compressor bypass valve (commonly referred to as a Blow-Off valve) on the intake tract and a Wastegates for the exhaust flow.
The Blow-Off valve (BOV) is a pressure relief device on the intake tract to prevent the turbo’s compressor from going into surge. The BOV should be installed between the compressor discharge and the throttle body, preferably downstream of the charge air cooler (if equipped). When the throttle is closed rapidly, the airflow is quickly reduced, causing flow instability and pressure fluctuations. These rapidly cycling pressure fluctuations are the audible evidence of surge. Surge can eventually lead to thrust bearing failure due to the high loads associated with it.
Blow-Off valves use a combination of manifold pressure signal and spring force to detect when the throttle is closed. When the throttle is closed rapidly, the BOV vents boost in the intake tract to atmosphere to relieve the pressure; helping to eliminate the phenomenon of surge.

Mine cannot be heard.....its setup to recirculate back into the air-box. Although myself, I like the sound of a quality BOV, others may not!

 

I don't know all that much about blow off valves but my Powestroke does not have one and it runs about 20 lbs boost.

 

you don't need a blowoff in a diesel. diesel engines do not have throttle plates, therefore, you can never build up compressor surge like with a gasoline engine

Exactly.

People, do a quick google search....its very easy to understand the theory behind these types of valves. I am not saying everyone needs one.....but they sure as heck wont hurt anything!

Does bov iliminate turbo overun on reflash?
