20000 RPM, 2.4 litre, 780hp

[GPI Racing]

For those of you who follow or want to see the latest 2.4 litre V-8 Formula 1 engine run on the dyno at 20000+ rpm, log on to www.cosworth.com and click on the V-8 dyno video. It's quite interesting to say the least. They are at just under 800hp and the engine has been running for only a few months so far. Rule changes went from 3 litre V-10's turning 19000 rpm to the 2.4 litre V-8's (for the 2006 season)to slow the developement of power. Rumor has it that Honda will break 1000hp by the Chinese GP in October with the last V-10's. Cosworth expects to be at or near 21000 rpm by years end.

Daaaamn, that's wild! You figured out how to attach a sportmaster to one of those yet randy?

That's why Nascar bores me.... Only GOD know's more about internal combustion and airflow than Formula 1...

Sounds like my GPI 2.5!

At the end of the video when it IDLES down to 9000 rpm, it sounds like it just loafing on a Sunday drive...

But NASCAR builders do 800hp with a push rod engine and a single carb at only 8-9000rpm. No multivalve, multi injector voodoo required.

That Voo Doo can also be reffered to as ingenuity...

I checked it out the other day when you posted this and forgot to reply. Now tell me why Merc didn't go with a 2 speed tranny and a lighter powerhead when they went to 4 stroke . Can't be any more complicated or expensive then a blower. Very cool link.

Those NASCAR guys try to conceal their technology, but they are much more sophisticated than they look. I was in awe when I toured some of their facilities and met some of them.

But a front running F1 team costs over $300 million, enough to pay for what, 20 NASCAR rides?

So sure, more money in F1 is spent on engineering.

Any bets on when Toyota starts running for the cup? A fraction of their F1 budget would be big bucks on a cup team.

Road and Track recently noted that a NASCAR engine's piston speed at 8000 is higher than a F1's at 18000 (rough numbers). Someone starting fresh without the years of development, and with no engine to benchmark, would take a long time and spend big money to make a big V8 turn 8000 rpm for hours.
