Increase the Turbo Sound?

I went to school with a kid with one of the supercharged harley davidson f150's, and dude must have had his blower ported, or kenne bell or something because you could hear the blower wail from a mile away. Pretty impressive, even if it still ran a 14 something 1/4 mile.

 

Arrogance of youth, would hang it out for all to see. With age, now like the quiet sleeper approach. My regular daily is the Tundra TRD Pro and have nothing to prove. Fun ride is an RS3 Roush Mustang and very hard to hide it......have no decals , it must be the culvert pipe diameter exhaust, quiet rumble at idle and foot wide wheels. Still have a few that try. As for as sound, the Roush SC is quiet as a mouse. Once you go WOT, different story.

 

I love the sound of a super charger.


Fun fact: the "whine" sound you hear from a sc is the screw warping and rubbing the walls of the housing.

 

Yeah, spartan is the truth, in 2004 STi's didnt even come with a radio, just a black double din that had the STi logo on it. I can appreciate the appeal of those vq nissan cars, they are bad ass. I am going to have to call you on the g35 sounding better than an STi . IMHO, the STi with those unequal length headers was THE best sounding car of that generation.

 

Interesting, I always thought it was from the straight cut gears on the screws.

 

Love a good supercharger. You guys remember the Pete Jackson gear drives people ran on smal block Chevy's? Those sounded pretty good also. The poor man's super charger!

Reviving this from the dead.

I pulled the "sock liners" out of the intake boxes, coupled with the TRD factory intake panels, it has dramatically increased the sounds you get in cabin.

This is correct. Your MAF (Mass airflow) sensor has accounted for the volume of air that has been ingested by the engine, and it goes into an equation with MAP (manifold absolute pressure) as well as a few other parameters that dictate how much fuel volume to be injected into the combustion chamber.

My GTI had a MAF, and running a VTA unit would dramatically screw your fuel trims up and cause a rough stumble when you would get back onto the gas after venting boost pressure.

TL: DR, if you have a MAF, keep it recirculated.

Alternatively, if you MUST replace your diverter/recirc valve, these are my suggestion and go to. Had one on the VW, and it held 26psi of boost with zero issues.

The TRD airboxes have a liner inside?

 

Stock airbox, TRD panel filters.

I'll grab a pic when i get home.

 

These things. Just pull them out

 

It is.

 

They simply pull out or do you have to snip off some plastic rivets first?

 

I just yanked it out. It will break the small plastic rivets holding them in.....not too concerned about it.

Again back to my VW days, we had something similar called a Snow grate. I imagine this is similar...cut down on noise, and let water drain if it ingested it. BUT, seeing as I do not plan on fording a river where the water level is at or above the intake ducts, i am confident in zero issues arising from this.

 

I was recently able to get a set of HPS Charge Pipes for an insanely cheap price. I hadn't intended to pick them up originally but I figured I wouldn't find a better price, and could have them as an option further down the road. All I really planned to do was eventually add decent intake & exhaust in hopes of improving efficiency.

I figured that if I install the charge pipes, I'd be better off upgrading the stock valves because of the increased pipe size; I'd likely choose the Plumb Back if I decide to install the charge pipes. Would I be correct to assume the charge pipes and (either of) the VR20 options would be completely useless without a true tune? This is the first vehicle I've ever owned with a turbo, so I'm still trying to figure it out.

 

If you’re at stock power levels or slightly above, you’re not really gaining anything with the charge pipes.

if you have upgraded turbos, and your flow rates are higher than stock, you’d be well served in it.
I say you’d be better off spending some money on downpipes and deleting the secondary catalysts.
And then a tuner.
The VR20s will provide no real benefit over the OEM ones on stock or close to stock power levels.

 

Frankly I’d be curious to see the airflow rates on the OEM Air to water intercooler.

in addition to the thermal efficiency of it.

but downpipes and high flow catalysts are going to be the biggest power adder here.

 

I kind of figured that would be the case but wasn’t certain, so I appreciate the input. I might end up just selling them, I’ve got no real desire to build up the engine. The further I’ve looked into it, I’m realizing how limited the options really are.

 

how much you want?

 

Haven’t given it too much thought. I’m going to wait a few months to see if anything useful comes out that will justify installing them. I’ll shoot you a PM if I decide to sell.

 

Not sure where he is at with the 3rd gens since the recall, but you might want to ping Jesse @TurboKits

He's on here almost daily, turbos are kind of what he does, and he's a cool guy to talk to.

 

may want to consider BMS BOV for the tundra if you're looking for the pshhhhhh

 

These turbos don’t have blow off valves to the atmosphere. The bypass is ducted righ back into the intake manifold. You’ll never hear a Pshhhh.

 

Got these installed on my TRD Pro pshhhh all the way

Interesting. So how do they stop dirt from going into those holes?

 

My understanding is that the BOV serves a different purpose releasing excess air when the throttle body is closed whereas it would be the air intake to keep dirt out. But then again I would direct that question to BMS

 

Do these prefilter for the filters?

 

nope.

 

3rd generation crowd is truly wild. Some complain about wind noise, while others complain there's not enough noise.

OP, why would you want your 60k+ luxury truck sound like a sheitbox?

 

I'm no mechanic, but that doesn't make sense. If it's releasing into the intake manifold, isn't that the purpose of a turbo and just creating boost? That pressure not needed has to be released externally somewhere otherwise it's never ending boost.
