100hp/ liter normal aspiration

[nthfinity]

Detroit is on the onset of 100 hp/liter over the next 10 months with a few interesting production engines...

how long is it before we are running 8000 rpm pushrod engines with 2 cams, and 5 valve heads, and variants of BMW's Vano's variable valve timing... and still 7 liters... 8 liters of displacement...

Will 100 hp/ liter no longer be the european benchmark of an engine? What will the european answer be? Turbocharging is coming back into style.. as can be seen in the 335 i, and the Milichilli concept from Ferrari being the future of the next super ferrari ("small displacement" twin turbo engine)

It's coming, and coming very very quickly...

What will it mean? Is this the future demise of engine building excess? will it be legislated right out altogether?

8 liters, 100hp/l ?

800hp? na?

[inso]

think tvr speed12 and you are there.

7.7liters and 800bhp.

Why go turbo when you can go NA?

Easier to tune and a lot less heat and weight and complexity - not to mention "instant on power".

I'm just curious if the giant lightweight engines are still going to be considered inferior even while hitting such a benchmark that has kept the euro's from loving our "yank tanks"

...
all the while, european sportscar marques have been increasing displacement slowly, but at a steady rate... Be it BMW, Ferrari, Lamborghini, Porsche, Mercedes... etc.

^Simple...4th law of physics. No replacement for displacement lol

Hasn't the new Viper already achieved this? I'm pretty sure it has some sort of VVT. Maybe I'm wrong, I don't know.

The turbo charging might as well (points out that a wrx engine is much less thrifty on gasoline then the big 427 in the z06).

It's about damn time! Look forward to it, other than the LSx engines, I haven't been too impressed by what comes out of GM's motor engineering department.

LSx is the biggest component coming out of powertrain production haha

maybe the 2008 viper motor has exhaust VVT? I'm not 100% sure... but the 2010 viper will have VVT

Honda achieved 100 hp per liter with b16 then b18 and now with k20a2 but the only problem is that engines are really small in cylinder. :x
