Do you think the new NSX or maybe even next gen S2000 will out due 120HP/Liter satus? I mean, if the new NSX had 4.0Liter engine, and could pull off 120HP per liter, then it would have 480HP. I can't wait to see how things turns out!

 

Unlikely. In economics there's the "Law of Diminishing Marginal Utility", sometimes incorrectly called the "Law of Diminishing Returns". After a point, the more of something you have, the less each additional unit buys you. Methinks Honda's reached that point with the S2000. So the additional 2 liters won't give an additional 240 HP. Sigh.

 

Only if they get to milking their prostrate a little harder!

 

Maybe Honda could put F1 engines into next get S2000

F1 engine spec:

The engine must be a 3-liter (183 cubic inches) V10 four-stroke with reciprocating pistons. Supercharging and turbocharging are forbidden.
Basic materials of the crankshaft and camshaft must be made from steel or cast iron. Pistons, cylinder heads and cylinder blocks may not be composite structures that use carbon- or aramid-fiber reinforcing materials.
Formula One engines generate approximately 800 horsepower.
Formula One engines have a maximum rpm of approximately 18,000.

800HP/3Liters = 266.7HP per liter! and best of all, 18,000rpm redline

True, but how often do F1 engines have to be rebuilt? I know you're not being serious anyways, but I do think Honda can marginally improve on the 120 hp/liter (just check out the JDM spec S2K). However, I don't think it'll come on the new NSX, for the same reason magician stated.

 

Honda also produce nearly 200 reliable HP/liter in the CBR600 F4i. Only $8K, and you'll have better acceleration than almost any prod. car regardless of price.

Nope, not high compression at all. You'd be lucky to get an F1 motor over 11:1 or 12:1 compression. They have huge bores and short strokes. That means they have to get compression through large piston domes. However, this can interfere with the combustion process and with airflow. Additionally, the effective octane rating of F1 spec gasoline isn't a whole lot higher than what we get at the pumps (our 92/93 vs. 94-95 R+M/2?). The quality of the gas is better, but not necessarily the detonation resistance. Mario Illien of Illmore Engineering has stated that the benefit of F1 race gas vs. pump gas is only on the order of 2% in terms of power. He may be sandbagging, but its probably in that range.

F1 engine are actually relatively weak on torque, most report them in the sub 300 lbs-ft range (and I have some other data that backs that up). 100 lbs-ft per liter isn't excessively high for a NA race engine and has been exceeded by lesser engines. Where the F1 engine makes power is not in Mean Effective Pressure (which can easily be converted to torque) but in sustaining airflow (and what MEP it has) at very high rpms.

Wow! Did you do all that math in your head? Nah, I bet you cheated and used a calculator.
