RE: Whats going on with auto makers???
thats hypatheticly that a 4.6 liter could make that. I think in time engineers will design smaller light engines that produce the same kind of power that old biger engines produced. like a 2 liter V-8 engine that makes 300 hp and 300 ftlbs. would be compare able to a 4.6 liter now.
Im just curious about the topic.

It'd could be done. But figure, 8 cylinders, you got a ton more of moving parts that can break... it'd be so damn unreliable.
The big issue all of us car freaks tend to forget, we are a very SMALL portion of the automobile industry. Millions more people buy sedans and SUV's than sports cars and most people are oblivious and could careless about HP and 1/4 mile times. This is why it doesn't happen!!

just kind of an aside point. yes the auto makers could do it. but imagine the accident rates. any idiot kid can get a drivers lisence. you want a 16 year old out there with a 3000 pound 880 horsepower car?

dirt bikes are the same way, I have a 05 yz250f its a 4 stroke 249cc 4 stroke motor, but get this 5 valves, and 2 cams, and doesnt hit the rev limiter untill 13,500 rpms. I also makes about 42-46hp stock. its a fasttt bike

RE: Whats going on with auto makers???
I dunno about everyone here, but being someone with an engine that does produce a good hp/liter and revs to 8000 rpm... it does sometimes get VERY annoying to have to rev that high to get into the powerband.
I get around town quite nicely shifting at 4500-5000 rpm, but it sometimes is a hassle to rev the living bejesus out of the engine.
I do know that there is a 5.0L V8 Mugen engine out there making 380 hp and over 500 ft lbs torque NA with ITBs running on premium. It's for Show use only though. If Ford and Chevy REALLY wanted to put the technology into their engines, it could be done... but not everybody wants a 9000 rpm redline and have to wait 80 years while the engine finally winds out there.
American V8s are built for torque, and they're tuned for driveability. Why mess with that?

Its not that you have to rev these engines up real high to feel the power. They have a steady horspower increase as the rpms go up and a nice toque curve. Its just nice that they have the ability to rev so high.
heres some dyno charts. For the 2004 liter bunch

RE: Whats going on with auto makers???
Just my two cents, I'd agree with 2000si. A lot of HP but look at the RPM range. Not to mention...torque. I haven't seen anyone mention that too much. A 500lb bike + rider is way less than 3800lbs. You have to have some way to get that weight moving. Torque is the only way to do it.
Yamaha may be 180hp but with less than half in torque. If you put the same equation into a car you'll be driving no faster than what you do right now until you hit well over 60mph and 8-10,000 rpm. [:'(] That or you'll have a twelve speed car to keep it in the power band all the time. You think your tranny gives you problems now?? Just add another 7-8 gears with about 900hp...no thanks.[:'(]
almost forgot..durability. If you say you own a bike with 30-40k miles on it people say that's a lot. On a car that's nothing. Motorcycles don't wear as well. High compression, high revs = shorter life.
