Increasing my rocker ratio

[need_a_VR6]

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.

[need_a_VR6]

Weigh it and measure it.

[PowerDubs]

I don't have the tools for that.. I only have 's

[newcreation]

Well can't wait to see what you come up with then

[fourthchirpin]

josh u dont have a triple beam balance?...opps.

When it comes making more power NA, your the man.

[xVolksR32x]

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.

[PowerDubs]

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.

Awesome stuff! Any new info? My best friend Henry wrote that Car Craft article. Classic I get all my parts from him.

Has anyone tried these shims?

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

[need_a_VR6]

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.

[my2000APB]

anyone have a link to the 16v 2.0t fsi cars using these shims?

[need_a_VR6]

Hit up Scott at Ferrea.

[PowerDubs]

this would be better to try out on a car with stock cams just to see what the gains there are vs a set of mild cams with similar lift.

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.

[need_a_VR6]

I think I did the math already, just gotta dig it up.

[my2000APB]

im eagerly awaiting results with credit card in hand

Josh was thinking if i am in there doing the rockers i never did valve train yet on a 24v.I was thinking of upgrading springs and retainers in the process not sure yet it it woud be worth it with the ration being low enough to still run the factory stuff.

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.

I have heard of that being done as well.

any updates on this? just wondering.
