Sure 4 valve per cylinder "pneumatic valve system". Any idea what a pneumatic valve system is. Sounds interesting, but the first few google hits didn't help.

EDIT: Wait, found this. pneumatic valve springs...

sounds awesome, great video

 

Vtec Range... 0-19000rpm.

 

I heard from a dealer that they were putting the 2.4 V8 into the 2009 S2000.


















J/K.

 

and price will be

A LOT

 

this may be a stupid question, and totally unrelated to the topic, but can someone please tell me when 5252 comes from? my physics teacher and i couldnt figure it out

 

Problem is that an F1 engine is built to only last a few hunderd km's. Then it needs to be rebuild and after a few races it's over and out with it. Therefore it can produce those enormous rpm's etc... But only for a very short life F20C is second best, although sometimes I wish it could rev up to 10k

 

It's the point where torque and HP are equivilant. Torque is a measure of turning force, HP is a true measure of actual ability to do work. 100ft/lbs of torque at 5000 rpms and 100ft/lbs of torque at 10000 rpms are equivilant in torque but at 10000 rpms, it's possible to do twice the work. This is why torque alone is meaning less. And also why we measure output in HP. The equation for HP must favor torque at higher rpm to show the potential for more output.

Why they chose 5252 could probably be found with google, but I suspect it has something to do with lineing up ft/lbs with an actual horses ability to do work.

OK I googled it:

that's a shitload of torque for 2.4L. A good 2.4L "street" engine only does about 160!

I guess high compression helps, huh?
