Re: Anyone have experience with the Autotech/Quaife cam gear (VeeDubbin16v)
I had it, it works good. You can do all kinds of adjustments on it. I would not reccomend it to a non mechanical guy since it can get confusing. You can easely over advance it and bend some valves.

Why did you get rid of it? Is there any other 16v cam gears you would recomend?

are u talking about a adjustable cam gear??? the last I looked, auto tech only made one for the 8v. I and quaife also makes a adj cam gear????

where can I find out more about the quaife cam gear. I have the tectonics modified stock adjustable, and am afraid of the keyway stripping out on me, like it has on many people and bending valves.

Do you mean this one

I don't know if it helps, but I have no experience with that gear, but the adjustment is the same as a 911 engine uses, and I have messed with those quite a lot. So I can't speak about the quality of the Autotech gear, but this style of adjustment is good. Pretty much infinite adjustment and a positive lock once adjustment is made.

Unless someone can provide the lift at a certain crank position for the 16v for the cam you are using, you may have to arrive at that spec yourself. If you have yet to install the cam gear you could check intake lift for the #1 valves at TDC on #1 exhaust stroke to use as a baseline. Did Autotech provide any specs or instructions?
Hope that helps

Well, the way it works on a 911 is; the factory provides a specification for valve lift at a certain crank angle. The engine is assembled with a best guess at cam timing. Then you put a dial indicator on the #1 intake valve and rotate the crank to, say TDC on the exhaust stroke and watch the indicator. As the crank approaches TDC the intake valve will start to open. If the lift is too much at this point, retard the timing with the gear, and if there is too little lift, advance the cam.Unless someone can provide the lift at a certain crank position for the 16v for the cam you are using, you may have to arrive at that spec yourself.

Re: Anyone have experience with the Autotech/Quaife cam gear (ValveFloat)
I do have the gear installed, the factory specs are well known and there are indications on the gear to set it up to factory specs. My approach was trial and error to see what works best, but there might be a more scientific approach to it. I know my Schrick cam specs so maybe I can figure out how to dial it in properly without too much guessing.
My question was geared more towards the physical handeling of the gear, and how to actually make the adjustements. Cam timing and timing belt fiddeling is not my cup of tea...

Is that what you were asking?
:edit: I guess I said that kind of backwards, you would turn the cam, not the outer part of the gear.

Well, basically the black center part of the gear is fixed to the camshaft, and the outer part is located by a pin that fits in one of the outer part's holes. To make an adjustment the nut is loosened, the pin is removed and the outer part is turned in either direction until another hole lines up, and then the pin is re-inserted and the nut tightened.Is that what you were asking?

Re: Anyone have experience with the Autotech/Quaife cam gear (Gewinn)
does this cam gear have the proper woodruf key that vw skimped out on it's 16v cam gears???? it has been known to break and strip out and bend valves. the 8v's had the correct design

Re: Anyone have experience with the Autotech/Quaife cam gear (ValveFloat)
My understanding was to unbolt that cover plate, take the pin out, give a little twist on the crank to position the outward part of the gear where you want it, put the pin where it fits to secure the gear, and bolt the plate back on to effectively reconnect the cam and the gear so they turn together again?

I understood it backwards of that actually. How would you go about turning the cam? :edit: I guess I said that kind of backwards, you would turn the cam, not the outer part of the gear.

Re: Anyone have experience with the Autotech/Quaife cam gear (AntoineJo)
Has anyone seen dyno graphs with different cam timing settings?
:edit: Are there any issues with having to advance or retard the exhaust cam the same as the intake cam due to the chain connecting them?
Just a thought...

Yea, that sounds right. On the 911 engine the cam has wrench flats on the end so it can be turned, so its easier to turn the cam than the crank, I didn't really think about how one would turn the 16v cam.Has anyone seen dyno graphs with different cam timing settings?

Re: Anyone have experience with the Autotech/Quaife cam gear (VeeDubbin16v)
so does this cam gear use the correct design of keyway that vw neglected to use on the 16v stock gears.

1. It has been stated multiple time that this cam gear is of good/excellent design...
2. what keyway are you talking about??? I think you are confused with the TT cam gear design. There is no "keyway" or any possible adjustment on the stock gear.
