I wish I only got paid 400k p/a

same. But half would be lost thanks to our lovely Govt if was paid in the form of wages

That was before Pneumatic valve springs though

Easiest fix is a restrictor on the turbo cars

Actually Renault introduced pneumatic valve springs on their turbo motor.

CSB.

along that line of topic, I went to a presentation by the engineer (Tony Wallis) who designed the Bishop Rotary Valve for F1 Merc engines...but was subsequently written out of the rules, apparently due to renaults influence on the matter.

interesting design if anyone wants to look into it. Beats poppet valve, pneumatic or otherwise hands down.

A links for those interested.

rotary valves are nothing new. IIRC there was a rotary valve head made back in the day for holden grey motors. Dunstan or something. And I doubt that was the first. Rotary valves have always looked good in theory, but have alot of problems in practice.

Main problem being less low end/mid range torque than an out of tune 10cc rotary engine

That was a different design.

There was also a French engineering company that designed a rotary valve f1 engine in the 80's (similar design to the engines you're thinking of) but I think they ran out of money?

The dunstan engine.

.

Aussie designed BTW.

Speaking of cylinder head design, I'm very much looking forward to seeing productionized versions of the 'Free Valve' infinitely variable pneumatic poppet valve actuation system Koenigsegg have been working on with their engine partner. Don't think solenoid valve actuation will ever be a reality with pissy low-voltage car electrics, but this other system has promise.

Wasn't saying they are new, but they were in development by BRV and Mercedes Ilmor, and were proven in both motorcycle and F1 engines to work, in practice.

No, that's exactly the same design principle, only difference is in the execution. Dunstan head runs the rotating valve shaft longitudinally with a port that opens to orrifices in the head casting, BRV runs individual rotary valve shafts at 90deg to the crank centerline necessitating a complicated gear drive system and completely incorporates the port into them. Same idea, different execution. The rotating disc valve is a different design, but shares the common trait that they really don't work reliably!

the significant difference is you can see actual images of a real life Dunstan rotary valve head, BRV ironically only had drawings of their design in that article about how they finally made one that worked!

that's kinda like when David Hasselhoff got in Pepsi ads on the back of the 'Don't hassle the hoff' memes

much lame, so last Thursday, wow

Yep.

Whoop-dee-doo basil....

I don't even know what it is but it seems lame...

[sh@un]

just more of the arsehole of the internet mooning the world, Dezz

[MatthewT85]

its just a more effective way of a team getting exposure then a normal sponsor....
just like this shithouse 'jandal' crap, was funny when he said it, but getting f**king annoying seeing it plastered everywhere...

And it continues....thjis time STR . Form Autosport

on JEV.... "While there's been some bad luck this year, the fact he has made Q3 three times (and would surely have done so in Bahrain but for a sudden change in the fuel-flow meter readings that forced the team to turn down the engine) shows he has emerged from the biggest disappointment of his career a stronger driver."

Would be simple to throw a bit of redundancy at them by getting them to run two meters

I was at the Sydney Retro Speedfest at Eastern Creek last weekend, and among the classic cars they had there were some old F1 cars, very cool seeing them out on track.

Team Haas Lola THL1

Benetton B186

Williams FW07

yawn... torro rosso = red bull

I've read the full decision of the appeals court - "As evidence of the reliability of its fuel flow model, the Appellant provided a series of graphs...Several graphs actually showed that parameters had changed from one lap to the other and that one cannot, therefore, conclude that the fuel flow model did not change notably... On top of this, it appears that not all parameters... were shown in the graphs"

That was their "proof" - doctored graphs and refusing to fully disclose the parameters used to esitmate fuel flow in their model!

Let's put it to rest already.
