Using a dyno you Average those readings and even if we allow the first one in its at best a sustainable 181. Thats 6hp from a rotary. If you'll check some of my other posts on this subject, a show on SPEED is doing an upgrade on a Acura RSX-S This car shows 210RWHP. They installed a cold air intake specially designed for the car and measured 4-6 RWHP with the hope that they will pick up an additional 2 @100mph from ram air effect.
Forgive me for what I'm sure is a stupid question, but what does RWHP mean? I'm sure it doesn't mean Rear wheel horsepower, since the RSX (and RSX-S) is a front wheel drive vehicle.
By the way, there is no fundamental difference in how a cold-air intake would affect a rotary engine compared to a piston-driven engine. The rotary engine in effect simply acts as three pistons at once, with the rotor dividing the cylinder into three stages (intake/ compression/combustion, and exhaust). So one shouldn't discount a 6hp increase in an RX-8 simply because the engine is a rotary.
