I recently decided to mod the air box like staged07ss by drilling various holes in the plastic filter holder and also switched out the filters with a K&n E-0777 filter. My problem is i haven't heard even a hint of whine. I've red lined it and don't hear a thing. I pmed him and he was also confused to what i did wrong.

 

Is the car making boost?

 

car is making full boost. so thats not the problem... i dont even hear any whine at all kinda eerie....

 

Then who cares lol

 

thought it was strange everyone that has done it this way can hear the supercharger whine and i cant. makes me think i did something wrong or something is wrong. I did notice my vacuum is under 20

 

Vac is where it's supposed to be. Pulley down if you want more whine.

 

more like any whine

 

Clean your tb and the inside of your supercharger to the rotors a lot of carbon and dirt will stop you from hearing the wine. The sound comes from the air being sucked in ,smoother surface faster air.

 

My supercharger is stock and she screams ..now I do have a k and n typhoon. But I clean my tb and supercharger every two or three weeks.

 

Pics of what you did

 

I'll try that. I find it funny that everyone else who did this can hear it when I can even here a squeak

 

Don't open your throttle body butterfly to much like a quarter inch no more ! You should be able to here the supercharger with a stock air box ...our dd is all stock and it wines a little on wot

 

I mean I have a 2.5 zzp cat back but it's not too loud. Idk man I'll have to go in there today

 

That's probably your issue. It's just drowning out the little whine a stock M62 makes.

 

Thats what i told him.

 

should be substantially louder with the airbox mod... zzp exhaust is quiet guys lol.

pics of what you did? Have you heard it from the outside of your car?

I mean **** i used to hear the blower whine on stock intake, stock pulley back in the day (damn that was a long time ago now )

 

yeah my zzp 2.5 inst overly loud or anything... I heard something today. hoping things get louder didn't think i filter had a "break in period" lol but i don't have pics of what i did. There is a thread with what i did floating around here somewhere. Just drilled wholes in the plastic filter holder basically

 

there is no break in period so its not gonna get louder. so what you got it what you got. blower should be whining a little bit.

 

hahah yeah i know there isnt a break in for a filter. But i heard a little on a second gear pull so ill take what i can get lol

 

How high are you revving?

 

Had an AEM SRI, and it whined like a little b***h!

Switched to modded airbox, and haven't heard a peep...

Its normal, just enjoy the silence while reminiscing about the whine

 

No its not normal.... my modded airbox is just as loud as my old aem intake, injen intake, xtc intake, and all the other intakes I've tested. It's just a deeper whine.

Fyi, the aem intake for the LSJ is not a short ram intake....

I didnt just drill holes in mine.... the size and placement of holes in my box were to mimic the airbox with out the bottom lid. drilling random holes will not do the same thing.

post a picture of what you did, maybe I can help you fix it up a bit.

Pulley size and how high you rev will alter sound as well, but as I told you before, when I drove my car off the dealer lot brand new, I had no problem hearing blower whine.

 

The AEM one is sort of both, lol.

It doesn't relocate the air intake like a typical CAI, since its already outside of the engine bay.

It just replaces your airbox with a smooth pipe and filter, which describes an SRI.

But by definition a true SRI shortens the length of intake pipe to give air the shortest distance to the intake manifold, but doesn't try to intake the coldest air possible.

I used you as an example when I modded my box, and when I switched from my AEM to the modded box, there was a HUGE loss in blower whine....

Maybe I did something wrong... But I don't think so though since my power remained, and my mileage improved (yay!)

I do have an aftermarket muffler. It's not loud or ricey, but louder than stock, so maybe its covering up some noise.

Guess ill be cleaning out my TB this weekend!

 

The factory SS/SC intake is a cold air intake.... doesnt need any sort of relocation!!

The AEM intake is an expensive airbox mod. Thats all it is. Dont be fooled by it. I used to have one.

 

Haha I know I know.... I got roped in too!

After reading your article, I'm back to stock filter with modded box.

I just noticed a BIG difference in blower whine volume when I switched.

Guess thats the price I pay driving like a grandpa and keeping it under 4k lol
