did i miss something?
i was on the acura home page to see if the a-spec suspension was still available and i noticed that the specs for the type s have changed. apparently now it only makes 201 hp? i was under the impression that the k20z1 made 210. any info on this?

Re: did i miss something? (cnyej1)
all engines are rated at the crank from the manufacturer, i was just wondering why the drop in hp from 210 to 201. what is the new sae rated system?

The new SAE "certified power" rating uses a new formula to standardize engine hp and torque ratings. I think in the most basic form it is something like this ... all accessories that come standard with a specific model (A/C, power steering, cooling fans, etc) must be installed at the time of engine testing ... I believe this new testing better accounts for parasitic losses. I think the formula they use to calculate hp was tweaked a little bit too (i.e. ambient air temp, barametric pressure, etc.) I'm sure there is much more to it ... but I assume this is just another way to try standardize engine output testing across the board with auto manufacturers. It both helped and hurt auto makers ... I think Honda came out very well ... I know some cars like the RL and TL took bigger hits ... but overall most of the new SAE numbers are close to the original stated numbers. (RSX 210 to 201, S2000 240 to 237). I read up a little on this some time ago ... so this is just what I kinda remember ... I am sure you can search around and find info on this.
