Sorry Whp. I admit that I don't know who is fwd versus rwd among most of the newer tuner type cars. As far as the rotary being a 4stroke there is considerable debate as to whether it can truly be classed as an otto 4 stroke because it operates as much like a 2 stroke as it does a four stroke. The reason being that it does not have a valve train but simply an induction cycle. Many racing organizations have banned their use for this reason. They have also shown much more affect to changing intake and exhaust systems like a 2 stroke does. If you watch Sports car revolution, on speed you will see that they dyno'd a RSX-S and recorded 210WHP. If you check the spec's from Acura(2005), thats about what they list it at. You provided a link to a site that appeared to be about the RX8. In any case you're missing the point I made about FLASHING on the dyno. Manufactures have been doing it for years in order to support their inflated claims. If you look at the graph, you'll see that the HP reading on the first graph Has a very sharp peak and falls rapidly. Thats whats known as a flash reading. I'm not ignoring whats shown on the graph, I'm simply trying to explain what is being done. I understand that there is a need to think that intake systems on engines are very restrictive. But, without some type of turbo, supercharger, intercooler or changing manifolds or heads or valves, you cannot get the amount of HP back that are being claimed. I too have over the last 40 years seen lots of manufactures claim to have dyno readings to establish that their intake, velocity stack, whatever, does what they say it does. In the end the claims turn out to be just that. If you want to see what you are losing by using a stock intake, simply take it off and dyno the car. Do it with the hood off or open and you'll get less underhood heated air. By the way, I'd like to see one of those 350WHP RSX's that are driven on the street.
