Just came across this, and if perchance you still need a Supertrap, I have two that I bought for a project, and never put them to use,

All sounds good with the exception of the oil mentioned. If you choose to run street oil, you must boost the ZDDP, or you WILL lose a camshaft. Ever since the EPA dictated dropping the ZN and PH to...

Did not race, did not have a car rented, but there was no way I could stay away from this one.
Elaine and I hopped in "Schmoe", our 2004 VW Jetta diesel wagon and headed out from the mountains of CO...

Now, that there is just plain ugly!
I second the opinion previously stated. Even new German stock bolts simply aren't up to what we do to these engines.....especially hard downshifts.
There are...

I've been wrenching on VWs since I bought my first one in 1964, and I just learned something here! Never thought to lube the contact points on the backing plate. Thanks!
(might help to explain so...

Had a couple of interesting conversations today.
First one was with EIS.
(This is the site that another poster listed as having Mahle P/Csets in their catalog.)
I was informed, "Yes, I have one...

Here is a free tip to one and all......Was anything BUT that for me, and necessitated a couple of long trips to correct it in customers engines at various racetracks.....and while I'm just another...

I wouldn't worry about that, Bill.
My guess this one will go on for a long time.

[quote=Hardingfv32;372225]My impressions I got from the 'smoke' coming from Palermo's engines over the last 4-5 years on the West Coast was that there were piston troubles. This impression was formed...

Jim and All,

Yup, started installing these in a few engines after showing them to Tech at the Runoffs several years ago, and being told their was no problem.
Yeah, I know, I know. At the time I...

G. Brian,

A bit off subject, but your point is well taken. I have a good friend who has a kart shop just up the hill from me, and he just showed me one of those engines. $159!
China is no match...

That is exactly why VW modified the ring grooves to 2.0 mm in 1966 and on. Show me a modern automotive piston that has a 2.5mm ring (excluding big diesels that top out under 3,000rpm). I have built...

I say, use the Chinese, and beat the snot out of it on the dyno.....I have, without a single problem.

Have you noticed that anyone knocking these pistons has a large inventory of the far more...

Brian,
Geeze.......How many of those outdated, clunky K/S pistons DID you get stuck with??

"Trying to reduce costs"....Dang, ya got me there!

I have absolutely no idea of what "trouble" you...

Tad,
Tell us what the markings are, or submit a pic, and someone on here will certainly be able to identify them.

Well, I'm certainly willing to learn something here. Would you please share with me how you open the groove without removing material from the already thinner ring land? Is that the area where the AA...

Steve,
You have always been a voice of reason, with the best concerns for this great class, (as well as a keen eye on cost) and I for one appreciate you and the years of effort you have invested....

Ohh yeah, That'll work! 1300s got their added capacity from a longer stroke crank (69mm vs 64mm). I've got a set of 1300 jugs I'll sell you cheap. The bore remained the same, but the cyls. are...

Decided to post this in two parts after my laptop ate the entire reply the first time.

The other perceived problem is this:
Imagine Average Racer Joe damaging a piston early in his season. To...

"Why not just cut them to 2.5 its an easy thing to do".

Actually.....not that easy. I have worked on alot of pistons (from VW and Porsche to Cosworth) over the last 35 years, and to chuck up a...

This is the first that I have heard the sad news. Tom was a gentleman, both on and off the track. He fought his last battle with dignity and a great attitude. I am honored to have known him and dealt...
