I think it’s the changes in the LT4 used in the blackwing for 2022. An improved version of the Eaton. It’s nothing earth shattering like a larger displacement, but would be more HP. I’m throwing out 20, since the Caddy is a little different. I’m just thinking and hoping it won’t make sense for Eaton to keep the current version of the SC in addition to the new one.

I don't think any of us know what makes the new Caddy engine different right now, it could be internal to the engine such a small cam change, could be better exhaust manifolds, or it could be something as simple a pulley change. 20hp is pretty easy to achieve so it could be anything. Either way, its not a major design change which is why I certainly think its possible to end up in the ZL1.

Only time will tell.

From the Cadillac announcement, with their LT4, it seems like the snout, lid, and maybe even LT5 TB. IMO - not much to be excited about, but for those wanting to keep warranties, the more stock power the better.

I DO like that blue... I don't know if I can pull that color off though...

There are some supercharger changes per MotorTrend,

“ The Blackwing's big, forced-inducted V-8's extra power—28 additional horses and 29 more lb-ft of torque compared to the LT4 in the third generation CTS-V, the car the CT5-V Blackwing mostly replaces—comes primarily from a combination of a new 1.7-liter Eaton supercharger, 46 percent more airflow into the intake plenums, new throttle bodies, and a new exhaust system.”

What colors is the ZL1 getting for 2022 besides Rapid Blue? What colors is it losing?

The engine is only rated at 18 more hp and 9 more pound feet of torque than our LT4s. Nothing to really get excited about in my opinion at least not to spend a lot of money to get to its specs. To each his own though!

Agreed.

Actually, the majority of “what has been upgraded” has been disclosed...

+1.

Mostly intake and exhaust. New TB.

Personally, the potential of Alpha 2 is especially intriguing. I fully admit that the new chassis is what I envy most.

CT5-V BW weighs in over 4100 lbs. 18HP don't fix that.

IMHO, 650 at 3832 trumps 668 at well over 2 tons. Not to mention an $85K base price.

I'm thinking that you can probably find 18HP with a ported TB, CAI and secondary cat delete for less than a grand...without a tune.

Yep! The performance difference would be nearly negligible if they had just rated it at 650/650 with that kind of weight...

Naa, if someone knows what has been changed it will get posted again here and it did. I can't spend all my life on this forum.

MT has this tidbit on the BW LT4:

There's also a revised oil pan and oiling strategy that Cadillac developed after a 24-hour continuous track test in the automatic CT5-V Blackwing, and a half as long 12-hour continuous test of the manual version.
