    You guys are all talking about the catch phrase "Volumetric Efficiency". As displacement goes up, efficiency goes down. That 1.8L Honda Civic engine is only overcoming the rotating mass of 4 pistons, connecting rods etc. There are only 4 pistons creating friction with the cylinder walls etc etc etc. Add Cylinders and more bore/stroke and efficiency has to go down. There's just no two ways about it. The OP has ricer troll written all over him.

    OK, I've got to jump in here; it's getting too "deep". Your Honda example doesn't work. The motor's 7000+ HP peak is useless for the street, and has no torque. That's why they don't sell. Remember this rule: you can only get torque from displacement.
    Porsche can only get 350 reliable HP from their 4.5L V8. How much do you think that engine retails for? I sell Porsche and Audi. Audi gets their peak HP on the RS4 at over 6,000 rpm. That motor is not built for longevity. It's a grenade. I don't want a grenade in my Mustang. Ford did not take "the easy way out". They did exactly the right thing. A totally non-stressed 300HP V8, that will last a long time, is easy to modify, and dirt-cheap to replace.

    This guy stopped arguing with us a long time ago, and relegated himself to all the other forums where he started the thread. Either way that was an interesting post. Is the RS4 really a grenade though? I don't know Audi's very well, but I would expect for such an expensive car that it would be a pretty durable one as well. :shrug:
