So I just finished swapping my L67 for the L32 and noticed several things. First, seems the old Supercharger whine is now pretty much gone. Just wondering if anyone else that runs a Gen 5 noticed this difference. I don't even really hear any vacuum/sucking type noise at low rpm (my CAI is a metal type JNB brand - that tended to amplify the Gen 3 sucking sound - ahhh will be sadly missed).
Also, under any type of acceleration, I hear more of a groaning/vibrating type noise - don't think it is the SC since it would seem an unusual replacement for a whining. I also have headers installed now and plan to double check that there is nothing moving, touching, vibrating while the engine is under load. In the meantime just wondering what the normal sounds are the SC makes under load so I could eliminate that as an issue. I currently have a 3.5 pulley installed.
Thanks!

Gen vs are supposed to a lot louder, so this is odd.

hows the power?

Mine definitely whines

Got the odd sounds fixed - was an exhaust baffle. I have not driven the car hard yet since I want to give some time for the ECM to re-learn the settings. However at similar throttle settings, the Gen 5 definitely seems quieter than the Gen 3. It does still have the nice sucking sound at low rpm (nice).

Separately, for anyone thinking of doing a full L67 to L32 swap, there was quite a bit more to swap then anticipated. Aside from what others in this forum mentioned, all the mounts are different, the oil pan was different, I'd say most of the sensors, not just a couple that needed swapping. I think I also had to cap off one of the vacuum lines to the new SC as well (had one more than the gen3). Once the swap-o-rama fest was done, not too bad getting the engine in. However header cross-over had to come back out, since the trans bolts would not go in past the cross-over. I'm actually quite surprised at how quiet the Headers are (used TOGs). You could barely guess there was a change from stock unless you have a well trained ear. Just like any headers though, they were a lot of work maneuvering during the install of the engine. Will be some time before I will have time to actually get to the track to see actual hp differences. I'm just happy that the used engine is running nice a smooth for now and I have my car back

Good to hear that bud. Kinda weird about it not whining tho...
