I hear on the F-1 television coverage that 19,000 RPM is currently the rule-mandated limit which cannot be exceeded either in qualifying or in the race. This is supposedly in an effort to control escalating costs.  ;o)  (I love it!)

>From what I have heard, sonic-wave tuning throughout the entire intake and exhaust system plays a big part in it. Pneumatic valve springs was a major 'breakthrough' in achieving ultra high RPM several years ago. 

An interesting tidbit that I heard on the TV from Steve Matchett on his Inside Formula One TV show was that at normal room temperature (say 70-F) a Formula One engine is completely SIEZED, and will NOT turn over with the starter. It is only after a period of time pre-heating it by pumping 180-F water and 180-F oil through it that it reaches proper internal clearances where it can be turned-over and started by the starter apparatus.   Wow!  ;o)

Did you guys notice the JCB diesel streamliner using all the fancy engine pre-heat systems at B-ville?  Who knows???  Maybe (probably) it was just for starting with extermely low C.R. for the high boost. ???

I've seen the diesels at competition tractor-pulls pre-heated to absolute boiling and cranked with 48-volts into a 12-volt starter, and they STILL use either to get them to fire!
