Wishing you the best on this project.
I Imagine the singer guys must have some interest.

993 Billet Engine Cases

Not cheap, but they are available; perhaps this is a shortcut for you.
Thank you - Adam.

We startede with the 1R mag. case as used in the 2.2. Then reinforced it as the 7R case with all built-in racing mods.

No additional machine work will be necessary.

Did our first test on the DMG MORI this weekend.

Computer renderings offer little to judge a project's potential but so far, I like what I see.
Cheers

Although there is almost nothing of less valuable than unsolicited advise I might suggest incorporating the head stud holes into the cylinder boss.
They can be counter bored if desired but additional head stud threads seems like a positive modification. The pictures shows case through bolts incorporated in the boss as well, I think that would be a mistake. It forces the builder to use 964 style case through bolts and washers.

Maybe even add support between the cylinders.....
Cylinder stability is so important.

Maybe we schould add strength throughout the area.

Tommy, my opinion is that you were on the right track the first time. What Henry is not taking into account is that you are NOT working with an original Porsche casting. I am not sure what material you are using, but any billet will be an order of magnitude stronger than a magnesium case, and you are running small bores.

You're just making the case needlessly heavier. I have done a ton of structural testing for my case and also had consulting engineers. My alloy is some 30% stronger than an equivalent Porsche case. Your should be too, but in order to actually quote strength you'll need to involve engineers. I know, expensive.

I would not worry about the strength of a 2L case made from billet *whatsoever*. It will be bomb proof.

My $.02

Adam.

Thank you for your $.02. I really appreciate.

I understand your point and maybe you're right.! It will be bomb proof.

As our billet alloy case is much stronger then the 40+ years magnesium maybe there is no need for the extra strength.

But we aim to make quality King here and Mr. Schmidt΄s point about adding support to the cylinder base because cylinder stability is so important is especially applicable with big bore.

We will offer the case in three different models:

Model 80 - With 80mm. head stud spacing.
Model 83 - With 83mm. head stud spacing.
Model 86 - With 86mm. head stud spacing

All these models can be made to order with your desired spigots size so choosing a model and Spigots size depends on your choice of cylinder - heads and final displacement.



Thanks - Olsen911 - Tommy Olsen.

I would agree that there could be some weight savings in the fine tuning of the final machining program but building in stability for racing application would (in my world) out weigh the need to save weight.
Small diameter (OD) spigots would limit the size and in turn flexibility of these cases.
As an end user, the ability to build a 2.0 this year and a 2.8 next year, with the same platform, would motivate me to choose this product over a more limit product.

The problem is that the repro cases already weigh significantly more than the originals. My case, which is made from a casting, weighs 10 pounds more than the original because of the unavoidable meat that you need to put on the case for the casting process.

Just by looking at it, with all of its square corners, it looks like Tommy's billet case will weigh probably 20 pounds more than a stock AL case, or 40% more than a mag case. This is significant weight in a racing application, which is apparently where Tommy is trying to build these cases for.

Again, he is working with computer models, and even Solidworks can calculate a weight based on the drawing. It would be an interesting thing to see how much his billet case weighs as drawn. Ironically, the smaller the bores are the more the case weighs.....

The advantage with Billet is that you can take off lots of material and there is no casting draft to have to add to the weight of the case, so in theory he could make his cases very light - much lighter than a casting.

The disadvantage is 50+ hours of machining time per case, the ridiculous cost of billet blocks that size, and the ultimate end price of the case. The company that makes them here in Orange wants $18,500 for a case and I am told they are losing money at those prices.

But you can make a hell of a light case out of billet, and strong too.

Yes - Undoubtedly, there could be some weight saving on subsequent fine-tuning of the case.

But here race cars must follow the homologation form as a part of the HTP - Historic Technical Passport - to be as authentic as possible in the class.

In homologation form 3025 - Porsche 911 1971 - The weight must be in 960 kg / 2116lb. Without fuel and driver.



So almost everbody must add some weight to get up to the 960 kg/2116lb.

I know that you want your weight in the middle and as close to the ground as possible, but I would choose stability and reliability on the case, anytime.

No need for casesavers or any additional reinforcement on this new case.

Almost there now.

Tommy, without reading through this entire thread I'll suggest something that may have already been mentioned. Easily removed, threaded galley plugs so cleaning is simplified.
Somewhere I've seen a threaded piston squirters so I would consider that option as well.

Both items patent pending USA and internationally by me is where you have seen it.

And will be vigorously defended, I may add.

You will take someone to court over a simple design change from the factory?!?!

You didn't design the first oil squirter, you only modified and improved serviceability of it...
