So forget about the 200hp, so the BRZ only runs 12:5.1 c/r? I don't think thats enough uphill passing power...
hah, but on a serious note I am curious about something and I'm sure the throng of very smart TCLr's can help me out.
Read the specs released not to long ago on the FA20 and was really surprised to find that its running a 12.5:1 c/r. Just off the top of my head I know the Honda J series runs 11:1, the F20C 11.7:1 and the K series varies between 9.5:1 to 11.5:1 so I was really surprised to find that Subaru put out a very high compression 4 banger, yet it seems to be lacking in power as opposed to other engines in that displacement range.
Now just take this with a grain of salt because I know its comparing apples to oranges, but lets just for a minute compare the K20a2 to the FA20. Both 2 liters, both 86x86 bore and stroke, both 4 cylinders, 16v's, dohc, and variable valve timing. The FA20 however has 12 years of technology advancements over the K, which includes direct injection, and im sure other small things.
When you take into consideration they make the same rated hp, and roughly the same rated tq at the crank, why does the 1.5 point higher c/r Subaru motor make the same as the K series? Does it really just come down to the intake/exhaust flow of the head design being less efficient? Much less aggresive cam lobe profiles? Another thing is the fuel economy. The RSX-S posted roughly the same numbers as the BRZ/FRS so does it just have to do with a boxer platform being less efficient in n/a trim versus an I configuration (though Porsche has clearly proven that not true with the GT3 engines) or is there other technical aspects that I'm missing?
