Man, you're an engineer, use your brain. The new revision to J1349 is what's causing the revised horsepower ratings. To achieve the certification, ratings must be repeatable to within 1% of the advertised numbers.
An even 200 was the planned horsepower rating, but the new SAE ratings system cut that number back to 197 hp at 7,800 rpm.
Don't you find it suspect that a car that just just had its numbers adjusted under the new system, which states that they must be repeatable to within 1%, dynoes at 197 "hub hp", which would put the actual crank hp at around 230hp?

Last time I checked, 230hp is not within 1% of 197hp.

I take it you didn't read the comments.

I did. One interesting thing that I came across was this:

In this case I don't think anything like that has happened, but the car is preproduction and the engine is largely hand assembled. So it may have components that are manufactured and assembled with much better tolerances than a stock motor and the development ECU may also be a little more liberal with the timing and fuel mixture than a production ECU will be.

The ones from your old 2005 RSX article look like it is a Dynojet chassis dyno and the print out is wheel horsepower.

This article mentions wheel/hub horsepower but all the charts appear to have been corrected back to flywheel horsepower.

I think you need to explain that before you say this one is really up 20hp. If the dynapack is actually printing out a flywheel horsepower rating that it computes based on a loss factor it comes out to almost exactly what Honda was rating the RSX Type S at for flywheel horsepower for 2005 MY.

geez-o 7000rpm for max torque and 7800rpm for max hp:confused:
how's the powerband on these things since most n/a 4bangers you haven the rev the crap out of to get any power

i love my rsx-s 05'. i've been having a lot of fun on twisty roads, learning to rev match, heel-and-toe, and just overall messing/learning more about my car in general. it really is a blast to drive, plus the mileage is awesome if you don't gun it on every stop lol. from LA to vegas, i had a 1/4 tank of gas left... this is on a 11.5 gallons tank. of course you have to buy premium gasoline though. buy it... it's just an awesome car for the money. :)
