I've seen the SyncLink before, looks very clean and would seem to work great theoretically.

Any other upgrades this time around?

Other than the linkage, mainly just the valve train: eliminating lash caps, and higher quality, longer, stiffer springs. The valve train should be good to 8k RPMs now no problem. I'm also going to run a 30 mm oil pump this time, with such high compression it looks like my rod bearings may have been suffering a bit.

Edit: Spelling fixed for Scotty

what is the compression ratio ?

10.2:1. That's getting up these for a pump-gas street motor (well, for a VW anyway). The motor runs really cool though, cooler than my old motor that was at 9.25:1. I have a really tight deck and great combustion chambers, its a really efficient setup, so it runs cool. You have to have the right combo to get away with it.

Edit: another reason I want to run the bigger pump is because of the Pauter rockers. I actually lost some oil pressure because of them. They basically just have a through-hole in the adjusters, unlike more traditional rockers that the oil goes from the adjusters through the rockers and then out at the shafts. Because of this design, they are way less restrictive, which tends to drop the pressure.

I never knew that pressure was related to the rockers. I always thought it was more from the clearance on the bearings.

Anywhere oil flows has to do with it. In the case of the Pauters, they don't offer much restriction to the flow of oil coming through the pushrods, so overall the path of the oil is a little less restrictive compared to the same motor with more traditional rockers, which in turn results in a little less oil pressure.

here is a picture for reference Boom..


also Pauters site says they've made some changes to the rockers .
As of the end of March, 2012, all of our Type 1 & Type 4 rockers will be transitioned to non-needle bearing type (as pictured above) where the aluminum body will ride directly on the hardened shaft. This type of joint has proven itself over the last two years of testing and in actuality, this type of contact wear surface replicates what you see in piston to wristpin joints in millions of vehicles. After this transition, all needle-bearing (at shaft) rockers would be special order.

Latest version feeds oil to shaft and roller tip/valve spring/guide areas of valvetrain.

Yup, that's what I was talking about, the oil just squirts right out the end with very little resistance. Pauter is transitioning away from the needle bearings to help them save on manufacturing cost, it's not an improvement...

Yea Konstantin was just asking why Pauter needle bearings are not as sore a subject as other ratio rockers with needle bearings... I didn't really have an answer for that......

I don't know, they probably use a much beefier bearing, maybe higher quality too. The shafts on the Pauters is huge, which means the bearings are big too... The Pauters run those rockers (with needle bearings) on some engines that have like 1000 lbs open and 500 lbs seat pressures, they are up to the task...
