I'm considering a magnuson heartbeat. How can I get a really good sound out of it? Anything at all?

Toddiesel

That's a 2.3L. It should put out quite a bit more whine than the stock 1.7L.

Can you order just the lid?

Toddiesel

Ordered one today. Thank you Billy!

Toddiesel

Since my car is STILL in the effin shop, if you get yours on before me, do upload some sound clips! I plan to when I can, but it's gonna be 2 more weeks at this point

badhabit_wb

Will do. I'm actually getting some work done on a quarter panel that I threw a rock through at VIR so when I get that done I'm getting it inspected and then I'l bolt it on. I had to order the hood liner too since I have a 15. Hopefully one of us will have it on soon.

I am anxious to get some feedback on this! I am thinking about one myself since I am planning on updating my tune soon. If I get one I will be sure to do a before/after dyno and give a full review.

Toddiesel

Well my car is out of the shop, but I'm out of town. I'll be back next weekend and I'll try to get it installed than and put out an update. I'm anxious to get it done, don't worry!

Also interested in this

Billy I sent you a pm.

I FINALLY got my NX cover installed today and DEAR GOD! It's unbelievable how much you can hear the whine now! Here's a video that should give you a good idea. To set it up for you: My Z06 is stock with the exception of a CAI. Windows are up, hood is down (obviously since I'm driving) and I'm in sport mode, so no gimping the exhaust sound

Sounds good. I'm planning to swap out my sc this weekend with the newer style with the taller lid. If all goes well I'll try to get my NX lid installed as well. I may wait a week or so to see how the new sc does before I swap lids.

Toddiesel

What's wrong with your "old" SC? As far as I know, the only difference with the newer style is the taller lid. I could be wrong

badhabit_wb

There are a couple of cylinders that run lean with the old one. I'm also getting an occasional misfire that we can't find a cause for. I'm going to give this a shot and see how it does. I don't have a track day scheduled until April 10 so I really won't know if this helps until then. If it causes any problems I'll post them on the forum. I'm just doing a straight swap so hopefully no issues.

Reggie927

Did you reuse your old supercharger lid gasket?

Toddiesel

Oh man, sorry to hear that! Hope it works out!

Not the main one, no. I ordered a new one from trunk moneys. it was like $35 shipped. I didn't know there are 4 little ones around the center holes though, so those I had to reuse.

Reggie927

Thanks for the quick reply! Mine is here just havent dont yet

The taller lid doesn't provide any difference in performance. The rear two cylinders on the LT engines run higher combustion temperatures than the other 6 so GM added more charge air cooling for those two cylinders by tilting the intercooler bricks inside the S/C. Tilting the bricks required raising the S/C lid. If you don't change the bricks there is no reason to change the lid other than looks. Tadge had talked about GM coming up with some sort of an update for 15 and 16 models but I suspect that intent ran into some technical and price challenges. There doesn't seem to be a way of swapping the intercooler bricks and the lid. The complete S/C has to be changed which then prices the GM version out the price range most Customers will pay.
