As you say far to many people do come into this being told by internet forums and the like what parts or brand of parts they need to fit to reach certain h.p goals and there are far to many internet experts who talk the talk only for you to find out they have no real world experiance, my advice get out there and get building, change things and write down what the changes did with diffrent tunes/settings.
http://www.ek9.org/forum/resource-a...-specs-comparison-honda-b-series-engines.html this is an excellent read, that explains a lot, and shows that it`s not black and white when it comes to camshafts.
Most people when speaking about power an engine made have in mind peak power. Though one might see a +5hp peak but gains 5K-8K could be well over 30-40hp ans significant increase in torque.
I don't have thousands of pounds to burn on testing engines, I don't have a dyno I can use at my lesuire and mist importantly, I don't have the time. In your eyes, that makes anything I say worthless.
The way I look at it, if I looks like a duck and quacks like a duck, then it's probably a duck, and in the same vain if the numbers don't stack up on a particular combination of parts then I feel fairly confident that they will not work the way I intended. I had a build planned for my blown b16b, and having seen a few similar, knew it was pretty likely to work exactly how I planned, but guess what, I ran out of money and I ran out of time! I still have that block in the garage, so maybe it will get built one day, and if it doesn't work then I'll be honest, raise my hand and say I got it wrong.
In the meantime, I'll continue to model and simulate the workings of a car in order to understand it. You think there is no value in this and that's fine, but a large proportion of the motorsport industry would disagree with you.
For those still interested in the original topic.
What are the benefits of over compressing an engine?
What are the downsides?
low to mid range losses are a few of the downsides.
Nice graph there vtec6000 like you say clearly shows very nice tourque across the rev range. from 4400 onwards just like you said there is massive mid range punch... what sort of power would 216 bhp be at the wheels... is there a rough conversion ?? good power for a b16A..

Would be about 181whp, it's roughly 16-17% from whp to bhp.
OK lets look at it another way, since I seem to have drawn a bit of a blank...
Remember though that there are times and area's that sometimes we don't actually want to be running MBT
1. We may want to run slightly retarded ignition to help keep cylinder temperatures down and the piston crown cooler i.e. to help keep us away from det under constant high load conditions.
2. There maybe a area that is causing us to wheel spin when coming out of a bend or in the wet condition. In this case datalogs would need to be recorded and ignition timing removed from those area's that cause us trouble. So we actually end up with lower power in a certain area of the powerband but a faster car (check that one out hey ? ? )
