      Scott, yes, one with equal length from intake bellmouth inlet to the back of the intake valve(s). Maybe I'll get motivated now that I know there's no cam compensation. I've been wondering awhile about that one.

      I'm sure there's a reason that they stopped doing it, could be something very 24v specific (is there injector specific fuel trim that is tuned for not having it?).

      I have put regular cams in cars with the 12v Mk4 manifold and all those cars made good power. I've yet to see a solid dyno from the 'foffa'/DRC front/rear asymmetrical cams on a US car.

      Must be something to it.

      Less hassle with having to calculate how much compensation to apply to it if they're symmetrical.

      *Finally* received the test rocker from overseas today.

      It may take a couple more weeks for all things to come together for the measuring to take place.

      Weigh it and measure it.

      That whole power collector design with the roller seems that it could hinder more than it could help for some reason. I mean look how many things you have added to the equation that need optimum conditions to operate correctly.

      Ever get these installed Josh?

      I know your busy with other stuff and you're still working on the stock mani project too.

      I drive a Chewbaka noise maker. What 'bout you??

      Still waiting on Paul, as last I heard he was changing a diaper, taking out the trash and looking for somone called Tim-e.

      There are quite a few inter-related components that need to be measured for this and other projects at the same time.

      Has anyone tried these shims?

      Anyone got a link to anyone using them on a 16v?

      The lifter shims? I think a few but no one is open about it other then a few people that race FSI turbo cars. I have a set for my new motor and a few others are going to be using them as well.

      The rocker stuff is on hold, my head is elsewhere (for Josh's other project) so I can't do much.

      Hey Paul... My car is currently apart again...

      I've got stock cams here.. care to do your chart math wizardry on stock cam specs?

      I'm considering throwing these rockers on stock cams to see what happens.

      Now i am not sure on this particular cylinder head if we can upgrade valve train without removing the head.I know some motors you can pull the cams and then fill the cylinder with air and do the springs and reatiners.It would be nice to beable to do it that way and not have to pull the head.Hopefully someone can chime in here if they done so.

      Hopefully we can got that route if need be without pulling the head

      i did some head work on my brothers supra a while ago. we got soft white nylon rope and stuffed the cylinder with it. turnd the crank pulley to compress the rope and keep the valves up. did each cylinder 1 by 1.
