For anyone interested in what the guts of our motors look like (that haven't had their hands in them themselves):



There are a handful of channels on YouTube that do these, and I'm not familiar with this one, but he seems to be pretty entertaining while being informative at the same time.

Whoever drove their car through standing water to cause the damage to the rods is an idiot unless they absolutely had to do it.

Papadakis racing also has an incredible detailed video of the teardown and rebuild. 2-port though, not 6.
I loved his video super interesting

I love that this dude is just impacting everything and letting it explode all over the place ?

The best number of ports.

Scandalous!
Two-port head spools faster, has better exhaust pulse pattern for twin scroll, and better thermal management d/t internal watercooled manifold.

I have zero engineering knowledge re: engines. However, based on my experience with other cars in the past, it leads me to believe that the overall potential power able to be pulled out of the motor with the 6 port is higher than the 2 port. Certainly nobody has tapped that yet given the ECU tuning options, but as more work is done in that area I expect it to change.

The early 6 ports were always tunable, FWIW.

True enough, though of course not for the 2022 cars as well, now. I think as a business proposition it's a tough call to put R&D into an expensive product, for a limited-run car, many of which now aren't (easily or cheaply) tunable. You're already looking at a small subset of a small number of cars, which may not (again, easily or cheaply) have the capabilities you need to have the product work. I can understand their desire to push development back a year or two on a kit for the 6 port version of the engine.

Totally right there. I had heard someone was going to slap a 6 port head on to a 2020, but I have no idea what happened with that.

Was this the one that got vapor locked and went boom?
