That sentence is pretty clear. If I don't actual test something myself, I can't form a valuable opinion. That means without experience my opinions, based on the knowledge I have, are not valuable. So, if that is not what you meant to say, be more careful with your words.

As far as this head stud things is concerned, I mention 993 Twin Turbo heads studs as studs that work and work well. Henry says they suck. I say they don't and he says they do. I back it up saying where I got my "knowledge" and Henry says I am some disciple listening to the "cool kids" and because I have never built an Porsche engine my posts mean nothing.

Yeah, I am going to keep quiet after that crap.....

Actually, putting words in other peoples mouths, introducing straw man arguments and pitting one group against another is really all you bring.
When asked the question "why use Dilavar" your answer is consistently "because these guys all use them and they can't all be wrong". Maybe not but never once have you offered an argument based in science. Your argument is always conjecture, urban legend, internet belief and hero worship.

hey, so I'm back and now I've got the motor apart, trying to find a supplier with stock who answers the phone and can get me some head studs. I'm leaning towards the Supertec studs but our host says they are out of stock and can't give me a firm date when they could supply them to me. Need a few other parts, but for the most part the motor looks very clean.

Any suggestions for an in-stock head stud that will hold up to my 3.6 application?

If you want to use the SuperTec studs, call Henry.

I am sure you can get the 993TT studs from Sunset pretty quickly.

Not to take any business away from Henry or Pelican, but if you come up empty, I have plenty of our Stud kits in stock.

[blucille]

Gave up on phone calls and emails to Henry, pelican was back in stock, so I ordered all the bits I needed and a 10% discount helped bring the price down to what I would have paid to buy direct from Henry. Thanks all.

I apologize for the radio silence out of Supertec of late.
As a hands on owner/operator, I was absent due to a prolonged Covid hospitalization.
We are restructuring delivery systems to ensure that services, parts and information are less "Henry" dependent.

That said, 993TT Delivar studs an inferior/ ridiculous design and I wouldn't use them in a stationary generator.

Here we go again....

You don't have to use them....but to suggest the 993TT studs are somehow "inferior/ridiculous" is, in itself, ridiculous! There are just too many high output race engines architected and built with them by respected people to take your position seriously. Just ask William Knight. He designed my 431HP 3.6L race engine and he spec'ed 993TT head studs...and he knows about yours.

That was easy........

it's all semantics, but putting this thread back on track, I'm happy I was able to get the Supertec studs. Was hoping to buy them direct, but Covid got in the way, sorry the team at Supertec had been so severely affected. Still, our host has them for only a little more money and was able to supply me with most of the other bits I needed, combined with a PCA 10% discount, I did ok.

I'm always happy to support the little guys, and appreciate the help I got from Henry on my '72 2.7 RS MFI/twin plug build recently. It gives me great peace of mind to know I won't have to worry about head studs on the 3.6 ever again.

Mercedes F1 completely dominated the Formula One championship with innovation for nearly a decade.
Every engine manufacturer from Ferrari, to Renault, to BMW, and Honda all used their "we've done it for years" mentality to simply survive.
Porsche engine builders in many situations are guilty of the same complacency.
Every time someone says "But these guys do it" they ignore the opportunity to achieve an even higher level of excellence.

Is that directed at me?

The people I know that use 993TT head studs don't use them just because Porsche does. They use the 993TT head studs because they work in their engines when other products did not.

I know they are working quite well in my high compression high output race engine. The 993TT studs were used in my engine because the guy who designed my engine, William Knight, said to use them.

If you don't know by now, I don't just take someone's word for something if I don't understand something. I had been reading for years on here about how terrible Dilavar was as a head stud material. Mostly from you. Pelican is just a microcosm of the Porsche world. So, I decided to do some research to see if William's choice was sound. First, I talked to William about it. Then, I talked with several race engine builders I knew and trusted. To a man, they all said the 993TT head studs were the way to go. No one said I should use Supertec head studs. No one said anything negative about Supertec head studs, but no one mentioned them either.

I am sure that your head studs work great. But that does not mean that the 993TT head studs don't also work great. Your massive bias against dilavar prevents you from having anything close to an open mind on this issue.

The idea that your are Mercedes in your example is hilarious!! If someone wanted a high output race engine built to beat the competition, your name isn't even on the list of builders one would go to....

[Henry Schmidt]

It's absolutely hysterical to watch ideology conflate personality with technical product assessments.

Guys as you may know I try and stay out of these threads................ But in the effort to help people have a good laugh....... Just Kidding... First an answer to GTC. I use DC 111 on all O rings. It conditions the o rings and adds a lot of life to the O rings..
Now for the head stud mystery.....
I sent a client to purchase Supertech studs last week... Look like a good product I have used one set, I do not have a lot of experience with them and on high HP builds I try and stay with what I know to work as clients do not like me to experiment on there car as a championship could be riding on it..
993 TT studs are NOT inferior at all, maybe Supertech are better maybe there not... It does not matter. I would use Supertech to support a small shop that is a Pelican member.
15 years ago I was racing an 3.5 liter turbo motor at 2 bar of boost.. I never had a problem with the 993 TT studs on a motor over 1000 hp...
Back to studs and my experience I have had problems with Raceware and ARP. I would not use either on a build that was much over 300 hp.
I have built MANY turbo motors back in the day and had excellent success with plain steel 2.7 steel studs. Montys motor made 645 HP at the wheels and ran plain 2.7 steel studs for a decade without changing them.
I hope this helps, sorry Henry had covid, I have it now and hope to be back to well in a week, about 50% better and I pray all of this craziness is behind us and we can move forward and start living again.. I am thankful for Pelican and the help it brings to people. BUT It does suck when I see talented people on this forum going at each other, William Knight

I find it interesting that Winders "master race engine architect" would believe that a production fastener designed to mitigate warranty issues (oil seepage on cool down not a performance enhancement) could not be improved upon by a design criteria that specifically targets the design flaws of this (cascade of failures) stop-gap fastener. Then to ignore the design features that by ease of repetition, would entice the builder to improve consistency of the assembly regimen. Build every engine exactly the same so slight design flaws are easier to identified. Sometimes group-think and fear of change creates a fog of complacency. Even the nut and washer design lack any semblance to situational excellence. A low quality barrel nut designed for speed on an assembly line fails "fastener 101" in engineering school.
As for the "race engine scenario" 95+ percent of all the engines built on this forum are either stock, slightly warmed over and spirited canyon cars. My advise is for those guys who really want their best chance of getting it right. That's why I'm here. 8000 posts designed to help the "one timer" get it right the first time. The suggestion that what works on the track is right for most DYI builders generally does the community a disservice.

William, sorry to hear you got the Rona as well. It's too bad your Padawan saw it necessary to bother you with this non-sense. Rest and be well.

[winders]

Actually, Henry, William Knight is the "master race engine architect". I am not and never have claimed to be that. But that does not mean I can't obtain quality information from reputable sources. Also, you should note that I have never said that the 993TT studs could not be improved upon or that they were superior to your head studs. My only point all along has been that 993TT studs work and work well. Oh, and a lot of reputable high performance engine designers use them.

I guess, in your mind, high performance engine designers like William Knight, Singer, Dawe, Jae Lee, and Jeff Gamroth live in a world of "group-think", "fear of change", and "a fog of complacency". Yeah, that's how all of them got where they are....

William is being quite diplomatic in his post. But please look at this statement he made:

"993 TT studs are NOT inferior at all..."

That is counter to everything you say about 993TT head studs.

[KNIGHTRACE]

This is still sad to me, I know Henry enjoys the back and forth post with Winders, he actually told me this I am not making it up. I agree with what Winders has said and I also think he in this thread has promoted Henrys studs and said nothing negative to stir up drama. I like Henrys studs and I think all Winders was asking him to admit is that 993 TT studs are also a decent option.

Not a single engine builder you chant as the "holy grail" have been willing to do the research. On the other hand, I've built hundreds.
If any of your experts want to discuss the science/technology, I'm available. I would be interesting to have someone with an open mind to discuss the "real" issues.
Even William admits he's not willing /his customer won't let him innovate.
after selling a thousand + sets, we have never responded to negative input.
For those DYI builders looking to install a more conventional stud (using the silly nuts :et al) the Canyon stud is even superior to the 993TT.
John and I have been in the discussions surrounding stud technology for a couple of decades.

I'm not sure questioning my expertise (with less than zero actual knowledge) qualifies as "asking him to admit".
Teasing gyzmos can be greatly entertaining.
As for the request to capitulate, why?
They are not a decent option for a plethora of reasons not the least of which is the ridiculous price. 99310117054 $57.75/ea from our host.
