AFAIK they still have cams, the pneumatic part of the system is the valve spring. It's pretty universal being used since the about 1993, I think Renault introduced them in their first V10. There is always talk of a camless valvetrain with every generation of F1 engines but I don't think (?) anyone has run one in a race yet.

 

Funny how the Cosworth sounds like it has gone to a slow idel at 9000 RPM's....

 

I'm down for 20 k rpms..... evo X anybody??? haha

 

LMAO!!!!!!!!!!!! Best one yet!

 

What about the old school f1 cars that were turbo driven? 1.5l displacement and 1400hp. Can't touch the hp per liter ratio.

 

^ They have no cams, the pneumatically operated valves is how they rev so high.

no cams? show link please

Check this link...http://www.formula1.com/insight/rule...gs/14/485.html

limited to not only have cams but they are not allowed to even use variable valve timing (MIVEC)

 

That engine is insane! I'm watching F1 right now I can't believe how this race has turned out so far... ugh!!!

and then

press control f then camless ot find it from the first link.

[snip]"Renault have not planned an Electro-mechanical system, which was commonly believed to use actively controlled magnetic coils to open and close the valves. Clearly the electrical and RPM performance required from the this system were not ready or suitable for a F1 engine. "[/snip]

 

Hmm, maybe with the Evo XX

Nice find Ted!!

Now I know why the Renault engine is better than the Cosworth. Better tell those Cosworth gus to work with the lights on, kindda helps to see what you're going and stuff.

 

It has been talked about for over 10 years now, there was a ton of speculation when BMW entered F1 with their V10 (and it was instantly very strong) that it was camless (which turned out to be untrue). The actuator technology is not quite there yet plus it seems that the rules prohibit it in any case (at the moment).

 

Well there ya go, I assumed that speculation was correct. Nevertheless, the day is coming, and it's only a matter of time . . .

 

Hey Shiv, how about a boost map for this one . . .
