The added strain is proportional mainly to steering angle compounded by the weight of the car, not much by the speed. If one is at full lock, you are either parking, or headed to the wall at high speed, and your C body TR are simply window dressing at that point. I assume we are not concerned...

At my dad's garage in the early sixties he had a Champion? sales rep show up and the big thing at that time was spark plugs not being properly tightened. I suppose his sales pitch often challenged the shop owner to take a torque test with a bank of spark plugs to a suggested value of what 40...

"2) The Torque in the "Torque & Angle" procedure assures the MLS head gasket to compress and seat to provide a more complete and accurate tightening of the head." What I am failing to see here is that procedure does not require a TTY bolt. My feeling here is the TTY solution reduces somewhat...

Not sure "load spreading, consistent loading, and superior, more consistent clamping forces" are problems a competent mechanic suffers or needed to be covered for those who aren't, as they are the one's most likely to reuse a TTY bolt in the first place with or without this article..

A very thorough redundant review of TTY bolt concepts, that was pretty much however IMO covered in just 3? paragraphs already in this thread. The main new takeaway here strangely, best outcome it seems, it reduces chances of overtightening, by widening the point between yield and failure, but by...

More back story with a Bill Frick reference: https://www.msn.com/en-us/autos/enthusiasts/the-cunningham-c-3-was-america-s-first-supercar-in-the-1950s/ar-AA1L8JM6?ocid=msedgntp&pc=ACTS&cvid=68d28e780f2f47b2a0cae489ed31dc86&ei=48

I'm trying to figure out the basis for those sliced long rams in the last pictures in your link, which was very interesting btw, thanks. A project on the shelf for me is to convert/improve a long ram to a short/long ram version, and add EFI. I'm trying to design an idle air valve in into the...

The issues seldom addressed is additional caster adds to steering force/strain on IFS/steering components, which causes weight jacking (by lifting inside turning side of the chassis (forcing that wheel down) and that forces down the opposite outside rear wheel (lowering understeer and increasing...

So, your point has nothing to do with "tubular", but moving the BJ back will increase caster? In regard to caster, in your opinion, how much caster is enough, and can you share any downside to be had with adding additional caster? Be careful, that last one is maybe a trick question.

I agree with everything except the last sentence. There should be required a marking on the bolt (a big star?) that indicates it's a one-use bolt, end of story.

That is not necessarily true, the issue here is when it starts to first "yield", which I already defined for this discussion, and when it fails can be rather far apart, meaning when it starts to "neck" down it is becoming thinner in cross-section and ultimately weaker.

I just recently got around to reading "The Sebring Story" by colorful Russian immigrant MIT Aeronautical engineer race promoter Alec Ulmann. The forward in the book (interesting read btw) is written by Briggs and the Collier brothers are mentioned often in the book. Collier County (Naples) just...

BTW, IMO, it worked out fairly well. It was steel I used etch primer, applied the black wrinkle, and then the grey. The biggest shortcoming was the black wrinkle was not as even as I preferred, and being black that was hard to make out, when applying the grey, it was easy to spot the slight lack...

That is a new awareness on my part, being my new car repairs are rather limited As much as I detest more regulations, and as long as NHRA requires new seat belts every 2 years, how about this law: FMVSS? requires any part sold that requires removal of one time/torque to yield fasteners include...

"He told me the story of his father's experiences as a self-taught auto engineer and that he had actually worked with Duntov and Briggs Cunninham developing cars to compete against Ferrari at Lemans! " It should be noted Briggs Cunningham's car won the 1953 Sebring 12hrs in his own car powered...

Explain first why a 1.625" OD? "tubular UCA's are needed at the least" to replace effectively a 3" 10 gauge I beam that has been supplied for nearly 2 decades almost unchanged, is still in use over 6 decades later and has a proven track record in billions? of miles.

Because the real stall speed is based on the engine's performance, and every car/engine combo is different. Advertised stall speeds are likely just an estimate mean for a typical combo. Testing one's combo tells an owner what they need to know. How can you not know that?

Beats me why you need to help your uncle Jack off his horse

Nope never punctuates every day.

I have no car pic to post, but very few Dodges/Daytona's were blue from my memory at that time, and the pic at the proving ground sure looks like a two tone paint job, and Charlie and Buddy were if I remember right more Dodge drivers (vs Plymouth) which seldom at that time were ever blue...
