NSX engine vs 3800 II
A friend at work said that the NSX has the most effeciant hp out put per L. on a NA engine. I do not think that that is correct but i could not find any thing on it so I decided to ask of you all what you think.
The NSX http://www.acura.com/models/nsx_specs_results.asp
I figure that the out put for the engines would be
3.0 = 84hp per L
3.2 - 90.6hp per L.
Also What do you think the out put on the 3800 II would be with the same compression and higher RPMs

Now, if you insist on talking about Bonnie vs. NSX lets see here...
The NSX has the following:
A Final drive ratio of 4.062:1
224 ft/lbs. @ 5500 RPM
290 HP @ 7100 RPM
8000 RPM Redline
and a 10.2:1 Compression Ratio
Titanium alloy Connecting Rods
Aluminum alloy with fiber-reinforced metal (FRM) cylinder liners
Oh, almost forgot about the gear ratios...
1st 3.066:1
2nd 1.956:1
3rd 1.428:1
4th 1.125:1
5th 0.914:1
6th 0.717:1
Now... what do you think a 3800 Series II engine would give you when built to those spec.???

An NSX costs 80000$ plus. the B32C engine it has is also the same one that is placed in the Odessey and and one of the SUVs Honda makes, just a different transmission. I believe the NSX runs a mid to low 14 in the quarter.

I figured out that the 3800 II with the same compression ect. the only thing that I changed was the RPM.
What i did is use the equaston Torque X RPM / 5252 = HP and figured out that for every 1200 added rpm over the max torque you lose 22.95 torque. So at 7000 RPM you would have a total of 172.625 torque resulting in 230hp.
172.625 X 7000 / 5252 = 230 HP
That leases me about 112hp short of the NSX
So can any one give me what the differences in hp or torque between the 9.1:1 and 10.1:1 so I could try to finish the theoritical output would be.

The NSX and S2000 also have 4 valve per cylinder and fully variable valve timing which is going to throw your calculations all out of whack too. The all aluminium construction will make a difference too.
