GM's XV8 concept engine vs. current Northstar engine

[Racer 20]

It's a 4.3L V8 300bhp, 290lb.-ft., high compression ratio yada yada pushrod yada yada displacment on demand yada yada

Or the current 4.6L Northstar with 275-300bhp and 290-300lb.-ft. of twist.

the top one uses better colors

Nah... really though, XV8 appears to be a better choice.

[Racer 20]

better colors...lol

[Porsche]

I'd say colours too, but it makes more Hp with less displacement so I guess it's etter. I think it needs bigger headers.

The engine project engineer for the Corvette said that "there is a lot more power potential in there" refering to the pushrod V-8 that made Corvette famous.

It's interesting how just a few years ago OHC engines were the fashion, just before that it was twin turbos.

Have more information on that new GM engine?

You are so right there!
Lets not forget 4-wheel steering, front-drive and Garfield dolls ...

I recall a pertinent observation some years ago from a prominent Nascar engine builder, when responding to derogatory Euro-snob comments about his 'neandethal' OHV race motors:
Comparing then-current F-1 engines to his Nascar motors, he noted that both engines produced about 6-700hp, but while F-1 units cost $400,000 and lasted maybe 90 minutes between rebuilds, HIS supposedly primitive motors delivered similar fuel economy, cost $20,000 max and went all day (and night).

His succinct response: "Who's fooling who?"

Hi-tech specifications/fantasy vs. Practical benefits/reality

Thunda Downunda: Ya but NASCAR is boring....

Racer 20: Perhaps Nascar is boring (it isn't televised here) ... but few motorsports are as utterly soporific as watching those giant egos poncing around line astern in the glorified soap-opera that masquerades as F-1.

[Racer 20]

I like F1 as a sport but your right about all of that soap-opera crud. It gets lame after a while. But surviving 4-5Gs in your chest then ripping though the corner and going at it again for what seems like an eternity should be "glorified" atleast in a small way right?
