Does this ever happen, it seems everybody did real well out of that group purchase for the headers through 928 intl. Also people did real well out of that Leda suspension deal. So why can't it happen with the cranks. These cranks are ridiculously over priced when it comes to chevy and Ford stuff and if Scat could set up for it why can't they just run a batch of 50 or so that the price can come down and then they could sell plenty of them.

Also I think it is time for the stroker cranks to go away from the old 2.1" pin and use the more modern 2" and if there was enough overlap on the journal go to the Honda size. This cuts the weight down in this area enormously. Saves friction too.
Just my 2 cents.

Cheers Greg

P.S I also know Moldex make great cranks but they do all there work by hand and volumes wouldn't cut the cost with them I don't think. Anybody got a stroker crank for sale?

Hi Greg,

For the most part, batch ordering is the ONLY way it happens. I think Don Hanson got a one-off Moldex recently (and that took a very long time), but prior to that Mark Anderson once again came through and put together a batch order for stroker cranks through Scat. (I believe it was a 10 unit batch). Devek put a batch order together right afterward through Scat, and I think both sets were fabbed at the same time although the two models differ in design . It's been at least two years since those cranks were ordered. The batch (years) previous to that one was a Devek batch, I think Sterling got his crank out of that batch.

50 cranks is a tall order for the 928 strokers. History shows that it takes several years just to work up enough interest for a ten unit batch. With the advent of forced induction systems for the 928, I think strokers are going to lose even more of their sparkle. Let's face it, you can get similar bang for a let less buck with a super charger (and soon with a turbo(s).

I've always said that any monkey can strap on a prefab forced induction kit and get major HP, but it takes a real man to spend 4x as much to build a stroker and get the same result. Oh well, such is fate.

One thing that bears mentioning, and this is just from my own observations, is that the recent availability of the headers from 928 Int'l., and the prior batch order of 928 Int'l stroker cranks are truly from Mark Anderson's excellent relationship with his fabricators. 928 Intl is an OEM parts /dismantler retailer, not a fab shop. I have a hard time believe that these custom hop up parts have much of a profit margin, and but for Mark's appreciation for the 928 community, these custom parts have to be more trouble then they are worth. I think both the stroker crank and header orders arised out of Mark A. ordering parts for his own race car, and then him going the extra step of burdening his fabricators with a small run of additional units for his customers. I could easily see a fabricator not having any reservations of making a one-off part for a reputable racer, but extending that to a short run of parts that are going to find their way out to the general public to be used on street cars, well that seems to just be asking for trouble. Somehow I get the feeling that if you or I called Scat or the header fabricator and asked them to make a crank or a set of headers, we probably wouldn't get the time of day. It's truly exceptional that Mark is willing to make the extra pitch to get these custom pieces made, let alone at a reasonable price and unbelievable turn around times.

Well stated Adam!

Think Mark mainly does this to "help out" a few of use wanting to build a high performance 928. Like you said, his business is really oem and used parts, not performance stuff.

I think moldex does one offs for 2200 or so. I've never seen prices lower then that for groups, so I was just expecting to get the crank when I needed it.

I am definitely in the monkey camp in this regard.

Moldex will cut you a crank, just don't expect it for over a year after placing the order. Then you need to spend another $300-$500 to balance it with heavy metal.

I thought Scat was willing to do one-offs now...........

I heard a rumor that three guys in Wisconsin ordered 3 Moldex cranks - they arrived in a very reasonable amount of time. It's just a rumor so I cannot confirm anything.

Could be true. Moldex can do stuff in 3 months or 30 months, who knows why!
I've talked to other Porsche shop's who deal or should I say use to deal with Moldex. Seems like they can never be sure when somthing will arrive.

If you want a good crank, do your homework. There are three top manufacturers out there. One will not do them the other two will. I can put together the nicest crankshaft order avaiable, but it would require at least 10 units and preferably 20. We specified that the pin size be 2.000" for small block early chevy pin diameter. Hondas pins won't work as well without the necessary overlap.

There is only one name in crankshaft engineering and we know him. He has been working on a 944 project set of cranks for me for several year because of a couple of problems on my end.

If you guys want the nicest cranks, I can get a price, but I would want at least 10 "interest parties" They won't be made by SCAT or Moldex either.


Let me know if you have any real interest, Greg.

Dunno dude. I don't think you're quite in monkey-land if you're talking about using a GTS crank with 968 pistons even if you do put a vaccuum cleaner on top of it. Austrolapithicus maybe?
