Looks like Jesus took the day off.

I'm sorry, but I just can't agree with this theory. Additional hp does not equal more accidents.

I believe that accidents are more likely connected to demorgraphics than the actual car.

That's why there are more accidents in the S2000 than Corvettes.

I didn't find very many stock RSX-S dynos via Google. But here's one from K&N's website. Compare the stock curve to a stock F20C. I don't really see any advantage to the K20.

Hard to tell with 100% certainty, but it certainly appears that the F20C has a torque advantage at every RPM. (Of course, different dynos, different days, yadda yadda. But if that RSX-S is representative of K20 engines in general, I don't see much of a big deal of iVTEC vs VTEC.)

Finally, to reiterate what others have said - Honda stated that the F22 is maxed out unless they wanted to go FI. And for whatever reasons (given Honda, it could be philosophical, economic, or even both) they don't want to do that.

Maybe Honda should upgrade the car with "dry weather tires" (aka slicks), a turbo that kicks in hard at 6k, and a super aggressive clutch type LSD. Instead of our weekly spin reports we'd have hourly reports, and Ralph Nader would have a field day.

I already go through back tires in 3-5k miles, and that's quickly enough for me.

Adding the ability to change cam angle by 50 degrees on the fly would allow you to smooth out the TQ curve and add more power. That's the only relevant fact needed to be considered. It would not be enough to silence critics. Peak HP would be the same. It would be a godsend to tuners, but stock it would add 5-10 lbs of torque to areas of the curve in the 2-6k range.

Your going to tell me a kid with 200hp has the same likely hood of crashing as a kid with 500hp?


Sure there are other factors, but power is also a big one, there is no denying that.

Don't look at the absolute numbers. Take the shape of the K20 curve and apply it to the F20/22. If you look at K20 dynos with good resolution it becomes pretty clear that they are much flatter than F20/22 dynos. That is VTC at work, which is the i part of iVTEC.

The K20 is not tuned to the same level as the F20. I am not expert enough on the K to know the reasons why from the perspective of the motor, but I am guessing Honda left more on the table with K for reliability and also due to the fact it's going into a relatively light FWD car. That's not the fault of VTC though. At worst VTC can duplicate a static cam angle so there is no reason to ever lose power with it.

Here's a decent article. As you can see VTC allows you to have more overlap at lower RPMs which increases TQ.

Looks pretty much the same to me?
