You shared it with a dick.

literally a fish posted:

It's loving witchcraft. The camshaft is in fact two shafts.

it's called CamInCam and it's ABSURD. (And still not as good as proper DOHC VVT)

Edit: OH GOD THEY APPLIED IT TO A DOHC ENGINE https://www.youtube.com/watch?v=Cpnv3lbagtg

I laughed at the "clink" noises they added during the assembly animation.

That's actually an incredibly simple and clean way to get VVT out of a single cam setup. All you're really adding is inertial loads, which unless you had a hollow cam you had anyway. But yeah, it's usually an emissions thing, when Volvo added VVT it was in 1999, and until 2004 they didn't even use it in a truly variable condition. It was either snapped to one position for warmup and then snapped back for running. It allowed them to fully eliminate EGR and air injection systems.

If it were me I'd take a bandsaw to those aluminum brackets on the engine and weld them after you dropped them down 3 inches.

Also simple enough to transfer the bolt pattern to a flat plate and just make all new mounts from scratch. 1 plate on engine, 1 plate on rubber, two plates cut to fit and welded in between. Design it in cardboard first.
