I've got the BMS filter, Mamo TB and an X-pipe as well on my '17. I wonder why you're not getting the loud whine everyone else has reported.

BMadden

Driven yours anymore BrookenookZ06? Can you hear the increased whine at all?

Just got back from running a couple of errands around town....found a few opportunities to get on it a bit and...heard no whine....just my X Pipe and Exhaust ripping the air apart.... sounds just as the stock lid did...will say though....the difference in responsiveness and SOTP feel is really noticeable....

BMadden

I'm disappointed to hear about the lack of whine, but the noticeable gain in responsiveness and feel might make it worth putting on. Btw, do you have the weatherstripping at the base of your windshield still on? I removed mine because it was supposed to help with the sound so I'm wondering if the new lid combined with that would make a difference.

BrookenookZO6

No I definitely think it’s worth putting on just for the performance gain if anything!!! It seems most if not all others who have switched lids commented on a noticeable increase in the Supercharger whine....I don’t know.....it’s weird..... and kinda disappointing that I’m not getting ANY whine at all....it was 1 of the main reasons for me purchasing the lid and switching them out in the 1st place....yeah I still have my weatherstripping on and that will stay on.....will be interested to hear your results when you switch yours!!!

Can you post a video so we can have a listen? Maybe try sending the manufacturer a quick email to see if it's normal to have increased whine after the installation of the lid

Don't you have to remove the hood insulation and the hood weatherstripping to get the wine anyways?

BrookenookZO6

That could very well be it Ruder....I haven’t and I’m not interested in removing either insulation or weatherstripping....maybe others can tell us their experience with removing one or both....

BMadden

I've got the weatherstripping removed, but I'm going to keep the hood insulation on. I'll report back when I get my lid installed.

FYI I recently called the manufacturer with regard to increased intake noise with their lid alone and they stressed that I would get no more sound from the supercharger than with the stock lid.

I'm going to post another video today with my PRR showing my supercharger sound with the lid. It almost overpowers my exhaust.

BrookenookZO6

Well...I don’t know what to believe now?? 🤪🤪 I guess the only way to hear it more is with the weatherstripping and Hood Liner removed....

Below is a video of the stock supercharger with the nx lid that also has the weatherstripping and hood insulation removed. Additionally I have a BMS filter, Mamo ported TB, Borla catless x pipe and BB Bullets exhaust.

Wow, sounds like my buddies Hellcat, awesome!

BMadden

How much is the microphone in the PDR amplifying that sound vs. what you hear when you're actually driving it? Can you really hear it screaming like that from the driver's seat because if so that's damn impressive!

BMadden

Compare SGT_G's video to this one. You can't hear any supercharger whine at all on this car.

SGT_G

It's pretty damn close. When I go to car meets, people love hearing the deep exhaust note mixed with the very high pitched s/c scream.

BMadden

Awesome. If I can hear anything close to that when I get mine on I'll be a happy camper. I've got the weatherstripping removed, but I don't think I'll get rid of the hood liner. I hope that doesn't muffle the sound too much.

SGT_G

It's a small difference to be honest.
