Weapon X Supercharger Lid Review (C7 Z06) Does it Make the Blower Whine?

[@jacobhauenstein]

In my experience smaller supercharges with higher speeds whine more. I've played with TVS1320 superchargers on the Audi platform and they whine much louder than the Hellcat or Z06/ZR1/GT500 chargers. Polishing them makes no difference, porting them or increasing the throttle body will make them deeper. Changing the pulley to overdrive them will shift the pitch up, and increase the volume a bit. The intake also makes a huge difference. Rubber/Silicone intakes dampen and remove the higher pitches, which sounds muted. Metal intakes sound OK if they are thick, with a lot of volume, but if they are thin they add some clangy bad frequencies. Carbon fiber intakes seem to yield the highest volume that sounds good, and that seems almost universal, it is thin but does not resonate like the metal ones do, so it does not vibrate but also does not dampen the whine like silicone does. If you really like hearing engine noise inside the car, taking a page out of the BMW scene is to modify your HVAC filter. It almost always pulls air from just below the windshield, and you can modify it to allow sound into the cabin through the air conditioning vents. Of course you still have to retain a filter, but this method has worked really well for a lot of people looking to hear more engine noise without making anything louder or resorting to electronic fakery. Your car sounds and looks great.

[@JMGENTERPRISES]

I appreciate your thoughts and tips! Sounds like you really know your stuff! I am going to try removing the hood liner and see if that makes a difference.

[@garyrichardson7592]

Because people that want to drive the automobile for cruising do not want to hear that. Ever thought about that.

[@K06E]

Inside the car is the most important. You want to hear it while your driving. This mod seems pointless. I want hellcat whine

[@JMGENTERPRISES]

Exactly. I just wanted to hear it in cabin. Waste of money.

[@knjpollard]

The lid upgrades are really so you can replace the intercooler bricks in 2015/2016 Z. So you add the larger 2017+ lids with the bigger intercooler bricks. I actually like that I can barely hear the stock one in Tour mode. I can't hear it in Sport or Track.

[@JMGENTERPRISES]

Oh I gotcha ya. Well I wanted was more whine. Haha. I guess C7Z's are just not the hellcats I wish they were. Lol

[@scenicsets6645]

Thanks for doing this video. I too asked them for z06 example clips but were shown the camaro videos. you would think both the vette and camaro would sound the same being the same engine and blower but obviously they don't. sorry to hear you didn't get the same results on your vette. expensive lesson. thanks for saving me from ordering one though. I was going to in a couple weeks.

[@JMGENTERPRISES]

Glad it was helpful! Yeah, the lid sounds AMAZING in cabin on Camaro's but it is non existent in cabin in Corvettes. I just wish Weapon X would have told me that prior to purchasing. All they did was send me the in cabin Camaro videos which made me think that is how it would sound.

[@smoothdrive3055]

@@JMGENTERPRISES because the Camaro has way more air flow than the corvette same for the c ts v it has a lot more air flow its how the car is designed

[@JMGENTERPRISES]

@@smoothdrive3055 Darn! Wish vettes had the same airflow. I want whine!!!!!!

[@BladedAngel]

So many of the NX Lid owners have made videos and bloat the forums saying how much louder the whine is, Yet compared to the Weapon X I hardly see a difference in Lid design on the outside or inside. So Is it the material? They're both billet Aluminum, so maybe thickness? Either way I haven't heard my whine since I got Headers! Seriously, I can't even hear it from in the cabin anymore. Even at low RPM, my Longtubes just drown any supercharger noise out. Thanks for the video though, definitely gave me some food for thought. I did a Corsa CAI, Ported Throttle Body, and barely hear anything over stock, so I feel the struggle to wanting whine!

[@JMGENTERPRISES]

Yeah, I am unsure about the NX lid compared to the Weapon X. I have emailed Weapon X several times as well as tried to get them to respond on Instagram and Reddit. However, nobody has responded. Pretty shitty customer service in my opinion. I was shown lots of videos with their lid on LT1 Camaros which made me think that would be how it would sound on my C7Z but it does NOT sound anywhere close to the same. I can imagine you can't hear any whine with headers! I bet your ride sounds mean though! Did you notice any performance gain with adding headers? I have heard mixed reviews on adding headers to C7Z's.

[@BladedAngel]

​@@JMGENTERPRISES Headers are more of a "Future proofing" mod. They don't do much without an upgraded pulley or cam. I'll be honest and say I did mine mostly just for sound and 2-step, since I don't want to trash the stock cats when spark cutting and going bang bang. Either way I'm glad you bit the bullet for us on this one. Definitely helped me steer clear of a mod on my list!

[@JMGENTERPRISES]

@@BladedAngel - Good info on the headers. I guess I am just worried about increasing boost on the stock bottom end with upgraded pulley etc. What level of boost are you comfortable with? I would hate to blow my engine!

[@BladedAngel]

@@JMGENTERPRISES I was at 13psi on Lingenfelter's 720 setup. It had Upper, Lower and Harmonic Balancer and...uhh yeah don't do that! I overheated like crazy! So much heatsoak! Can confirm it made great power though! With my Headers, Midpipe, Exhaust, CAI, and those pulleys, I had almost 700WHP...for like my first 3 runs, then I lose power after!! Yikes! I'm thinking of stepping down to just an upper only. Maybe 12psi this time? Still looking at options. I'm also redoing my cooling. The Z06's lack of cooling is starting to finally get to me.

[@JohnnyCorleone]

@@JMGENTERPRISES The zl1 camaro doesn't have a "felt" hood liner maybe thats why its louder on the camaro over the corvette. Maybe try removing the hood liner and post another video, Im interested in the results. Do not remove the weather strip at the rear its bad for aero.

[@bobbyspanino6874]

I read your corvette forum and thinks it’s pretty shitty the company didn’t reach back out to you. Hope this continues to get more views. To maybe bring their attention to it

[@JMGENTERPRISES]

I agree. I tried to return it but they said I couldn't after it was installed.

[@egg250]

Great video. Thanks for the review. Does this require any tuning? CEL?

[@JMGENTERPRISES]

Weapon X said it dosent. I never got a check engine light. Seems to runs like it did stock

[@nyplantingsgardendesigners5645]

The whiners on the Corvette Forum would always complain about 1. Whine noise and 2. Don't want a bulging hood. (Those things I like) So marketing folks saw that and dumbed down our superchargers. Finally the ZR1 development went with taller hood. These guys likely never got into FI in the first place. Well, thanks for the video I'd like to know if it's easier to add if you're too add alcohol injection or nitrous with this lid or something to do with performance.

[@JMGENTERPRISES]

I hear ya. Yeah it sucks most people do not want blower whine or a taller hood. I like both those things too. I think the NX lid is better for adding alcohol injection or nitrous because it already has the ports for it.

[@dsmubz]

I'm going to test this lid on my brand new dynojet to see if the increased volume makes any performance gains.

[@JMGENTERPRISES]

Please let me know what you find out! 🙂

[@chriscar7798]

[@dsmubz]

​@@chriscar7798 hello 👋 I will post a video on my channel in about 1 week or so, the lid is on and it definitely wines like a baby hellcat blower lol, I have to put it on the dyno to see if there are any rwhp gains.

[@dsmubz]

​@@JMGENTERPRISES kzbin.info/www/bejne/eYjHY4qYZrmLZqM finally tested the sounds part, performance part is next

[@Cyberronnin]

The issue is the corvette does not have a port that routs intake noise to the cabin, the Camaro has a tube that plugs into the intake and routs to the cabin, there is also a delete option for this too. With the stock LT4 blower my guess is you’d have to flat out remove some of the sound deadening material between the engine bay and cabin, or get a aftermarket blower…not to mention the rear trunk is open to the corvette cabin which pulls more rear exhaust noise into the cabin which can block out the super charger wine

[@JMGENTERPRISES]

I didn't know Camaros have the already installed. That explains it. I recently purchased a shawn foster sound tube and will be getting it installed soon! Hope that finally allows me to hear it!

[@Cyberronnin]

@@JMGENTERPRISES yes sir, in fact Roto Fab sales air Intakes for the Camaro with and without the sound tube… I had a 2017 SS and it was a big thing in the Camaro community to get the sound tube delete.. please upload a video with the Shawn Foster sound tube id be interested to know how it worked out for you!

I don't have the part number anymore. The part number should be the same across all chevy dealerships. But I suggest calling around to different dealerships. Some dealerships were wanting $400. I called a few ans eventually found one for $150. Also, I just installed a Shawn foster SC sound tube. So much whine now! If you are looking for more audible whine, I highly recommend it.

[@MichaelGreco]

Was just researching this. I was more interested in the power side. Was also looking at Kong, are you going to do the Stage X? I'm trying to find ways to add power without flex fuel, cam or headers.

[@JMGENTERPRISES]

I have heard and read about the Stage X. I was thinking of doing a Kong ported blower but probably won't. I don't want to increase boost at all. Plus having intake, ported throttle body, x pipe and weapon X lid, I find I have more power than I need. At 600whp its got enough power without being to hard to handle on the streets. In my opinion that is.

[@MichaelGreco]

@@JMGENTERPRISES I hear you. I'm trying to get to 600 or so. After an AFE intake, Corsa Performance NPP exhaust and Tune in only at 550 wheel which is what it should be stock. Turner is blaming crappy California 91 octain.

[@JMGENTERPRISES]

@@MichaelGreco - I highly recommend the throttle body I got. Tony Mamo V2 Ported Throttle Body. Good for at least 15whp. It made an amazing difference on my manual M7 transmission. Throttle response was quicker, no more lag from a dead stop and more power. If you are trying to add more power without adding meth, cam etc, a ported throttle body will help you get there. I did a review on the throttle body here - kzbin.info/www/bejne/h2q7Y4aFfqqXj7c

@@MichaelGreco I made over 600 rwhp with just an intake GM box and E50 and flex fuel sensor. 😅

I got the same issue with my blower on the ZL1 , try porting it ?

[@JMGENTERPRISES]

I have heard porting it will make it louder. I guess I just don't want to spend $1,500 and increase boost which I know porting will do. I guess I will just be happy with the way it is. I really do wish it was louder though.

[@buddthomas4297]

Vent your hood, or get a vented aftermarket hood... otherwise, live with what you have.

[@JMGENTERPRISES]

Yeah since publishing this video I installed hood extractors which really bring out the whine outside the car. I also installed a FosterSC sound tube which REALLY brings the audible whine inside the car. Highly recommened.

Wow I’m really sure they aren’t making that lid for some one who wants to sit there and make “revs” and make the whine come out.
