Big Wasser?

[Type 5 Joe]

Sorry, I'm not shure what I was thinking.

I think I ran some really short H-beams in a Wasser I did years ago... I used 2 litre Type IV pistons, dished stroker in a 1914.

Oettinger's boxer6 engine for the Vanagon brings back some interesting memories. 20 yrs ago I was working at VW's R&D center in Wolfsburg, and would take as many opportunities as possible to detour around the workshops to see what projects are shaping up. Remember seeing a Vanagon on a lift with a 6-cyl engine- it was a VW case with another 1/2 case welded on! A few years later I learned that this project was shelved by VW but sold the tooling to Oettinger.

(Re:Strictly Foreign...)
I met that guy and yakked for awhile at the portland bug-(whatever) a few years back.

Seems a good sort, and has a great rep.

Fast car too.

John, any thought on bottom end combos?

With a 15cc combustion chamber, the piston "crown" basically IS the combustion chamber, so you would have almost full control over the shape of the chamber so to speak, and getting 15-17:1 CR wouldn't be too hard, as it is with a T1/T4 head with real chambers.

I was also browsing over at Boston engines website, and he makes an interesting observation that the 2.1 rod big ends get badly out of round, a leading cause of ventilated case syndrome.... The 1.9s don't as bad, and it's the same rod...

A chromoly rod/stoker crank/Squishie NA combo (with matched cam/lifters) might last longer than stock, even al elevated power. Any thoughts?

I'm still lusting after a turbo setup, but the above combo could sell well just for Vanagon rebuild apps, esp if the "chip" for the digijet was included... Of course the Subaru swap kit guys would be after you;-)

(Some worked but still reasonable AMC heads would be a bonus)

I thought the story with the 2.1 throwing rods vs. 1.9s was the use of stretch bolts for the 2.1s. The thought was supposedly the stretch bolts were losing their torque and therefore the nuts holding everything together... thrown rod. I thought it was mr. B. bob saying this, too...

I'm going to stick with the 1.9 rod bolts, though.

Stretch bolts would... Stretch, and might cause failures, but would not be the CAUSE of the big ends getting out of round.

Excessive clearance causing poor oiling and throwing a rod causes failures, and that is what the article was about, if you think about it.

I am suggesting that a good quality aftermarket rod (CMo) may be a RELIABILITY improvement due to less suseptability to big end distortion..

Here's what got be thinking...

If it was only bolt stretch he would recommend ARP Bolts... The 1.9s rod big ends get beat up too, just not as bad due to less stress...

So this subject is particularly interesting to me because i am building a stroker 2.1... displacement will end up at just hair over 2.3 (82mm x 95b), and am concerned about the rods. The rod length to stroke ratio is just a hair on the short side (1.67), so side loading may be a concern.

Who makes quality aftermarket rods that would fit our wassers? I need to figure that out really soon as i have a set of rods queued to be rebuilt, clearanced and balanced.

Wassers just use t4 rods, right? Can you point out a quality replacement?

Thanks,

Actually they use wasser rods;-)

T1, but shorter, and with a 24mm pin.

!!!Correction from earlier in the thread---T1 length, 24mm pin. A CrMo rod may be a big win in longevity based on what I am thinking... What's less likely to get beaten up on the big end, a H or an I beam?

There is some motion as to setting up working combinations, but at early stages, all involve custom pistons at this point.

I have posted some musings that a 96x80 combo with CrMo rods may actually outlast a stocker in some apps... Just looking for other folks thoughts.

I suspect John at aircooled.net has some things in the oven.
