I thought that it would turn results similar to the RL's or TL type S, its not even close. However, it is to be noted that this engine is very environmentaly friendly, in that light, I guess its very good. The Dyno shows the compromises of power and environmental stewardship. Just wait till the diesel shows up with a dyno that shows 350lbs of torque at 2500 RPMS and 200 HP at the 4000RPM redline! The VTEC faithful will have a heart attack! Unfortunately, the era of our dear ultra high rev gas engines and ever bigger power is on its way out, for all but a few models. The name of the game in the next decade will be higher milage and fewer emmisions. It will be similar to the change we saw in the 70's but this time the changes will be permanent. My suggestion is for those of you that cherish our classic Honda engines to go out and buy your s2000's now since they will be the last of the ultra high performance VTEC gas engines.

This is because it's the automatic with the VCM. Stick the 6spd coupe on the dyno and THEN tell me it's not impressive :)

What does VCM have to do with anything? Isn't VCM only supposed to kick in only in light cruising when you don't need all 6 cylinders to maintain your speed?
Honda should have put a sport shifter in the automatic so you can hold a gear if you want to (such as on a mild-moderate hill).

So disappointing that performance on this bigger and more complex engine is not better than the old engine. Makes people want to run out and buy a new 2007 while they can still do it.

The most dramatic improvement of the 2008s is that the coupe version's styling looks much better than the old coupe.
Sedans looks are debatable.

If I recall, there were only rumours of an I4 Diesel (N22) to be used in the Accord. That will NOT get you 350 lb. ft of torque and 200 hp. In fact, even if you had those numbers, diesels don't feel like that because they're slow revving and heavy.

We are talking wheel HP here. a 25% loss is less then normal. My 65 Chryslers engine on a stand pulled 350 big ones and 370 tq. The wheel HP is a mear 260 and tq is 250.

The trans and drive shafts take lots of power away. The more gears the less power goes to the wheels. At least that is what has been told to me as long as I can remember.

It should also be noted that with only 500 miles on the engine, it most likely has a fair bit of loosening up to do.

All of the J series we have owned seemed to loosen up all the way to about 3,000-6,000 miles.

It still put down noticably more power and torque than the 2003, but most likely had some breaking in to do. That could potentially account for 10 or so more whp. Maybe more.

Also, with the way VCM works, it doesn't boost the low end as much as the old VTEC system which is still used in the coupe 6 speed, so the powerband may not be as broad. Unfortunately, without a way to keep the auto tranny from kicking down, it will be almost impossible to compare, coupe 6MT to VCM 5AT.

I am not sure the news is all that bad... I have an S2000(AP1) and I also just picked up a Civic Si sedan for daily driving duties. Let me tell you, the K20Z3 is a very very nice piece of work. Infact I drove the two cars back to back Saturday... the Z3 has a lot more useful torque in the mid range that it makes a much better daily driver. While the z3 doesn't rev to 9k and does give some up on the top end (compared to the F20C), the engine pulls hard, is smooth, and sounds fantastic. All is not lost yet... the Civic Si is a FANTASTIC package.

I just bought an AP2. It pulls much stronger than the Si at all RPMS. I have never driven an AP1. The Si feels like a "regular" civic at low RPM with a vtec "swan song" at the higher end. Owning an AP2 I'm a little mystified by the old all or nothing stories of the AP1 s2000. The AP2 has a very linear power delivery, when it goes "on the cam" it just feels more urgent. The car pulls vigorously over 3K. In city driving you can essentially drive the car all day in 3rd and fourth except from a stop. BTW my diesel specs were pure conjecture ;)
