That is so cool!!

damnit! i was just going to add that to this thread...oh well, im always late!

what exactly are they doing? are they breaking it in or....???

 

No clue, but I love the headers getting that red and the flames coming out of them.

What are pneumatic valvesprings?

And the high valve angle seems surprising to me?

Anyone know if it is true that a mechanical engineering degree is required to work for an F1 team? Or know the requirements? Cant imagine how awesome it would be to work on one of those and at the same time travel around the world to some of the most exotic places for free.

 

Think of a small airbag with a hole in the middle in place of a valvespring. Pressurize it with nitrogen and it's a pneumatic valvespring... Now, eliminate the rubber airbag and have an upper lower cups which telescope into each other. Put a seal, similar to an o-ring between them.

That's very basic, but it should give you the idea.

Now how about controlling the pressure inside the pneumatic valvespring (PS), say varying it with rpm? There is very little mass moving, and the PS either has few reasonant frequencies like a metal spring, it has vitually unlimited stroke, and it's rate is controllable. It really doesn't have a cycling rate (rpm ) limit.

My guess is the pit crews for F1 have very few engineers doing the grunt work. If you were a Honda engineer, there's a small chance you might get to work on the F1 team, but of the many hundreds (or is that thousands) of people involved, very few get to travel with the team.

High valve angle? Not sure what you mean. Intake and exhaust valves are on opposite sides of cylinder.

 

The throttle response is unbe****inglievable.

yes it is!

 

It says 25* intake valve angle. Seems high unless its totally different than what Im used to in SBC being 23* the least performance oriented angle.

Crazy sweet valvespring technology. I want some, I have this bundle of cash laying around that I dont know what to do with

 

It's a pent roof chamber..... So think of a Hemi type setup where the valves aren't angled the same way away in the bore they are on opposite sides.

Remember you can do anything with a blank sheet of paper!

Got it...

Anybody else have problems with the video Bret just posted freezing but the sound continues to play?

 

Some of that comes from extremely low rotating inertia and virtually no flywheel. The ones that have a flywheel attached to the crank have a clutch diameter smaller than an ob doc's "10 cm" magic number. (I'm getting an interesting visual here.)

I haven't figured out how they launch so well.

 

That is so wrong.......

Then again after Rich's post about the 293 girls of CZ28 collection.... I don't know which one is worse.... but then again I'm not related to Rich!

Is he a frustrated saw bones?

Rich

 

Sorta. Never could get past "blood and guts" however.

Orthopaedic Biomechanics was a possibility, but it didn't really exist in '61, and all those ObGyn guys did was talk about their work, not cars.

FWIW, the best docs I've met have a good basic understanding of things mechanical. It's a narrow view, I know, but understanding "how the world works" helps in every profession and almost every situation I've encountered in life. That's the ME in me speaking out. Ever wonder why mechanical engineers (MEs) have such a big ego? Shoot, we even use our degree to inflate the ego. You Medical Deities don't do that of course.

 

Well, people do have a big advantage over machines - they heal. But OTOH a 5-axis CNC machine never sued anybody
