Hello all,

I installed the JWT popcharger yesterday, and I am hearing a "whinning" "screeching" noise. Its not the normal suction noise, I am use to that on my other vehicles, this one is a whinning , screeching sound. It is not constant and seems more apparent at WOT. I just want to see if this is normal of did i connect something wrong or tighten something too much.


I did check to make sure that nothing was rubbing or touching. As always any input would be appreaciated.


P.S I know with the installation of some products, you have to reset the ECU, is that the case with this JWT Popcharger, if so, how do i do it on the Z?

thanks

Nigel

 

you dont need to reset the ecu...my popcharger whistles between like 3 & 5 RPM. it almost sounds like a turbo whistle. It is not to loud, but just loud enough for me to notice..

 

Rollin ...I think I passed you a few weeks ago on 376...your the only other lemans 350z I've seen in the burgh...

 

Thanks rollin350z,

So the "whinning" is normal? are there other people hearing this as well, or is it only on some of the JWT popcharger installs?

thanks

 

When I had an intake on my wrangler it wined heavely from 2,800 rpm to 3000rpm due to an air leak...check you hoses to see if their tight again

 

YEAH it is supposed to whine like that, and it works great.

Hey philly I dont think it was me...There are 2 others around here in my color

Mine is hooked up though....did you sell you TRACK brakes?

 

I think it is normal. When I first installed the JWT, it sounded almost like running your fingernails across a chalkboard. The sound would last for like a second and then stop and start up again. After a day or two, you will get used to the whistling sound and you gotta remember, you are hearing this sound while inside your car driving with the gas pressed, so you are getting a lot of road noise, engine noise, etc... You should pop the hood and have a buddy gas your car in neutral, then you can really hear what the sound is.

 

track brakes are long gone...is it me or does no one in Pittsburgh no what a 350z is

 

Same here there is a slight whistle while at WOT. It does sound slightly like a turbo. Man I better not get addicted to that sound $$$

 

I like the fact that there is almost no 350z's in pittsburgh. makes me look better when I roll by...

 

Mine doesnt whine...its hisses or whistles when you step on the gas at idle or if you are accelerating around 2800 RPMs and then i cant hear it anymore after about 4,000 RPM's because it turns into a roar.
