I just saw that today and was wondering the same thing, pretty slick.
Trying to wrap my mind around this. Appears to be a hydraulic solenoid that will affect the timing. Looks to me like it would affect the belt tension more than anything else. I am FAR from an engineer though, so I would love to know more! Strange that there is a blanket wrapped around the rest of the engine.
There are others on here who could expound upon the idea more than I can, but Chrysler did something similar to this on the Ultimate Daytona(?). I always forget what it was actually called. IIRC there was a cam phaser deal that pushed on the timing belt in between the two cams and adjusted the timing in the way this guy is doing it. Very cool to say the least that he's doing it to an 8v.
I just read through that thread on the WV forums. He has a ton of cool stuff going on there.
That guy is on TD.com. I recognize the Water/Air setup. I might have his build thread bookmarked.
Acanell and the rest of the "cnc junkies" were discussing prototype vvt cam gears on td. Research the vari cam. There were other desifns considered, that we are looking into now.
And yes, jay ive seen that ac water cooler for his system on td. Not too long ago i read about it.
The camshaft gear is rolled a few degrees (looks like retarded and should be) when the solenoid is activated. I thought about doing such a thing for years now. I think a slightly longer timing belt would be needed to get enough movement to make it worthwhile. I also think a pretty large HP gain and extended RPM's could be had while not loosing (could even gain some) low RPM power. I have been retarding the camshaft up to 6 deg. on my combos for years. It would be interesting to find out at what point no gain in HP could be had by retarding the camshaft.
This is interesting.

I bookmarked the writeup. Can't wait to see dyno results
I'm a member of that forum and let the OP know that he has a thread about his car on TM. I linked the thread and invited him over here, hopefully he'll sign up and give some first hand info.
Sorry guys for not posting my build here too. I've been a member here for a while now but due to time I was just keeping up the post on td. Now a couple of other sites have some of my experiments posted so I will try to answer any questions to members here that I can also. All these mods are just that, experiments. Just like many others there are things we would all like to see done to see how it works out. Now that my kids are raised and I have the time and the perfect car to work on I thought I would do some of these mods. The water to air intercooler mod worked out better than I had expected. This winter I'm working on the vct mod. I'm using a stock belt with just the factory tensioner removed. This gives 10 camshaft degrees of timing control, pretty much the max you need for a single cam system from what I've read and saw from synthetic engine program benchmarks. The dyno this spring will tell the tale though so I will try to have it done by then. Any questions? Ask away!

Experiments by people that think outside the box=Awesomeness Do you think you will need an addtional idler pulley when your timing is fully retarded or in 'loose' mode to control belt harmonics?

Well thanks for joining the forum to post. I'd love to see some better pics of your setup, just because from the one up top it looks pretty amazing, but more would be better. I'm not versed on the variable valve timing, so I don't know what to ask, but others on here are and I'm sure they will come up with some good questions for discussion to get everyone thinking.
Thanks again!

Idler pulley is homemade also but the belt moves on both sides nearly evenly since I use two pulleys. Here are some videos that might show how it works better. The spring loaded tensioner just barely moves to keep the belt at the same tension no matter where the vct is.

Two idlers,good plan, I didnt pick that up from the initial pics Thanks for posting here, I havent ventured to TD.com in many years and wont be either so I appreciate the cross posting here

Ok I will start a project log here and try to put in the more experimental stuff that I've done to the car over the last year or so. It might take me a while to get it all up to date but don't hesitate to ask any questions or make any comments you want over on this post-

Have you thought about using a linear actuator instead of an air cylinder?
I'm not sure how you're controlling the amount of timing adjust, does it have stops to limit the adjustment?
