Isnt your Meita a newer one? Would you have to smog yours? In cali the engine has to be the same year or newer, how is it in your state.

Bad bellybutton mode. I remember Hotrod or carcraft testing a monster Meita years ago... LOL they blew the rear end. Still awsome stuff.

I'm not sure how strict Lawton is, but OKC you can do pretty much whatever to your car, as long as you aren't street racing or purposefully causing a nuisance the cops don't care around here. I've had friends running open headers on their supra's and 2 running open headers on their stangs while they were getting exhausts built for them, no one got a ticket.

There aren't any vehicle inspections or smog checks around here.

funky said..."can" does not equal "are". They have not shown they can even get close to 100 bhp/liter without a blower. We are talking production engines that will run for 200k miles here, not race engines or lab experiments or tuner projects."

funky... not too up on the liter thing but... what cammer, normally aspirated production motor of 5 or more liters is getting 100 hp per liter? GM crate engines of 540 inch are getting 750 hp... the 383 motors are getting 440 hp. These are factory motors from GM with warranty. I am sure they will go 200k. It is pretty easy for the crate motor builders to get 600 hp out of 350 inches. the cammer motors are just too bulky when you get into the V8 configuration.

Lazs, imports are doing 100 hp/l without superchargers:

Acura RSX type S:

2 liter / 200 hp (normally aspirated)

Engines you listed:

383 ci = 6.3 l / 440 = 70 hp / l
540 ci = 8.8 l / 750 = 85 hp / l

Nobody is keeping up with the 8's except for the exotics. Nobody is doing it reliably in the V8 category. But that doesn't dismiss what the imports are doing with the hp / l on the 4 cylinders.

But then... 200 hp in a 3100 lb car is still just 200 hp. Putting it to the front wheels via traction control is going to reduce the effectiven hp even more. And nobody is delivering on torque.

I am saying that for a V8 in the 500 hp range nobody is making cammers for pruduction engines. I am saying that with a little 4 banger you have all the room in the world to have overhead cams and such. The pushrod motor is much more compact... it is easier to get the torque (which is really what you feel anyway) by going to large cubic inch compact motor rather than bulky small cubic inch cammer.

Ferrari, Mercedes, BMW, etc. all have 4 cam V-8's in that power range.

You don't feel the engine torque. You feel the acceleration of the vehicle which is equal to the engine torque times the overall gear ratio divided by the radius of the tire divided by the mass. For any given vehicle speed and vehicle weight, the engine with the most power will give the most acceleration given proper gearing.

None of them are what I'd consider even remotely reliable. There really isn't a comparison to the raw torque and horsepower available in the american V8's yet. Eventually... maybe there will be. But right now there isn't.

Ferraris are famous for problems but I don't think Mercedes and BMW are known for engine problems. Maybe you know something I don't.

I'd love to see Honda put a couple of S2000 motors together and make a 480 bhp 4.0l V-8. But they don't really make cars heavy enough to require that much power. Anyways the Japanese regulations pretty much rule out anything more than 300 bhp.

Nuther thing: In the 500 hp range you will find most of the Euro motors are V-12's. They will absolutely dominate an American V-8 of similar displacement.

I have not heard good of any high hp import V8. Not Mercedes, not BMW... nobody. The 500's do OK as long as they're not tweaked out. The 300 HP ones are just fine. They'd definately rank higher on the scale than BMW's 4 liter V8. I've not heard good about that engine from anyone that's had one. Though... I don't know anyone with a 2001 or newer that has one. The BMW 6 cylinder is a great engine. The 8 will amaze you at it's cost when it comes time to have the head gaskets replaced (again).

You know the only reason why you even feel torque is because the RPM is perfect linear line. Ha, all the nerds start laughing!

Ok... for small motors a cammer is a good idea. If you want to get into the real expensive exotics then you can get 500 hp out of a "production" cammer V8 but ...

there are engine builders in the states that are getting 700 hp out of pushrod all alluminum V8's with 2 year warrenties and they build thousands of them every year. The engine costs less than the "production" ferrarri motor and has more power and is easier to adapt to any drivetrain and is more compact. I would say that it is at least as reliable and way easier to tune. and.... has a much wider powerband.

when you get into the thousands of hp there are no cammer motors. Top gas and fuel dragsters..

Torqe band is what is important in a street car... that is what you feel. if you have a small hi reving engine with a very narrow torque band you will be constantly shifting. Punching the throttle when the car is not on the torque band will result in very little acceleration. For everyday use, the wider torque band is more useful.

I have no problem with overhead cams... they are just not the panacea the you make them out to be.

reminds me of a rice-burner bike I once had..

power band from hell

gimme a big 4-stroke anyday.
