'21 Generation 7 Car news

I remember hearing "stories" about Rusty Wallace coming back from 2001 Daytona 500 and have crew cut "the spider" out of front clip on his chassis. Said they cars were too stiff. Maybe it was just a story?

Your statement about engineers leave a whole lot things out in not only the design process but economics. But whatever, this ain't Billy and the boys designing a race car.

Just can't wrap my Brian around the use of box tubing for upper part of chassis. How is that not a huge difference in crushability? My concern is car-to-car crashes. And before Charlie comes in and says, the roll cage is round tubing...i'm referring to the clips.

Thank you for implying I have the slightest clue what we're looking at. It's mostly all just shiny metal to me. Put some feathers on it.

The car is designed to crush front and back. This extends the "period" of impact. The center section is built to different specifications for more rigidity. Too much or not enough is not only figured, but crash tested in real life.

I'm trusting the engineering but some things just don't sit well with me from an "eye test"
 
Crushable, no?

Have 4 buddies that are mechanical engineers. Great guys. School is nice. You really learn when you have to make your designs work in the field. I also worked on cars for 45 years. LOTS of engineers designed & built some REALLY stupid ****. I know that some would say it's the bean-counters fault. Worked in Ford dealership. The had a problem with wiring that runs through column shift lever to OD button breaking where the lever pivoted in pick-ups. It was a DESIGN/engineering issue. This problem went on for 15 years or more. Had made a connection with a techline engineer by actually sending him pictures and MY changes to repair. It wasn't even remotely hard to see the problem. He wanted me to replace whole column in next one and send old one to him so he could see what the problem was. They had been receiving the old broken levers with wires hanging out of them for 15 YEARS and couldn't see the problem.

Just a little frustrating. Engineers put their panties on one leg at time just like you & me.

How much of a spike in energy when that aluminum bumper collapses and the actual rear clip has to absorb some energy? Of course I know nothing more about this that you or anyone else here. Just stating my concerns. Hope I'm wrong. Great thing about bolt-on clip is can change designs fairly easily. They may eventually have a 130mph clip/150mph/above 150mph? So clips for Martinsville would be different than Bristol or Dover. Another for 1.5 mile tracks. Plate tracks would be the usual unicorn. Maybe at some point they'll let the teams build the clips?

There are good and bad engineers, just like anywhere else. In your case that problem would be hard to simulate in the design process and it is from the same company that had spark plugs blowing out the heads and they continued to stonewall consumers by not making it right and fixing their vehicles. But having said that, these Nascar cars aren't mass produced, it's a totally different situation designed for racing not passenger driving and they don't have blinkers.

I wouldn't hold my breath. Everything they turn back over to the teams is one more R&D line on the Expenses ledger.

The point Jr made on his show is valid. The companies building parts for these cars are going to sell X amount then almost none. How do they stay in business after the first year or so? Since the teams HAVE the staff and equipment to build the clips, which would then be certified by NASCAR, that removes an item from the supply line. I know it's very unlikely. Just a thought.
 
Too be clear...I believe this car build process is a necessary evil. The sponsors aren't paying as much. Have to cut expenses. I actually like the idea of bolt-on clips. Just don't understand the use of box tubing for all sections. I'd expect lower box and upper rail round tubing. Like we've always done.

The engineering school in Miami designed a bridge that fell down before it was even completed/loaded. Engineering college. Sorry but I put little faith in engineers. Just over-paid math geeks.

Guess some of you have never seen what appeared to be a successful company go bankrupt.

I think you are missing the point. The point is by having non favorite outside vendors building the parts, it saves ALL of the teams from spending buku amounts of money.

Which is easier to work with, Square or round tubing for what is essentially built and designed as a bolt on replaceable assembly?

All it takes in one chassis test like McDowell at Texas to settle everything.

Case in point, the front and rear sections of the car are heavily damaged and took the brunt of the energy of the wreck, while the center section was intact. It's designed that way. The new car takes it one step further with removable pre built modular front and rear clips.
 
Yes, as I recall your position was that the vast experience you gained changing shim stacks in motocross shocks trumped the conclusions reached by the Ohlins' ... wait for it ... engineers.

I don't do lists. If I had you on ignore I would have missed today's nonsense.

Some of this boards members seem to have great difficulty understanding exaggeration and poking-the-bear. Or that 4 of my best friends are engineers and quite enjoy my bitching about how dumb engineers are. I mentored 2 of them in how to take things apart so you could put them back together. Learning how to take things apart without breaking them is difficult for some. Most people learn it by...breaking things. Was motorcycle/go-karts/etc related when they were kids.

Two were/are engineers at WVU. Was involved in the VW diesel emissions cheating deal. They were doing emissions testing for municipalities looking to purchase fleets of trucks/busses. Alaska, Mexico City, etc. Had two tractor trailers with a hub dyno. Drug it all over the country. Was pretty interesting stuff.

Worked with three of them at a drilling company building a new double rig. Had two Cat C-15's in a shipping container with a huge amount of hydraulic filters. Here it is:

Vertical and Horizontal Wells | Target Drilling | United States

Target Drilling's 480 Double Mast Tophead Rig was designed to drill shallow horizontal wells with total MD of 14,000 feet even with formation true vertical target depths of 1000 feet, and for tophole and large diameter vertical wells.

Okay, I now officially have no idea what you're trying to say. If you're saying now that your "little faith in engineers" was sarcastic or jibing, it didn't come across in text. If that's not what you're saying now, then never mind; I'll drop the subject.

Don't worry about it. I'll find somewhere else to be.
