Either Mugen is fleecing the hell out of its well-heeled customers or Honda's S2000 is so well maximized that extracting extra horsepower takes Herculean effort.
Mugen, of course, claims the latter reason and cites a two-year design and testing program to come up with a series of parts that make meaningful performance improvements.
Mugen, as an engineering and parts contractor to Honda, one of the world's finest engineering companies, did its homework, and the 15 horses Mugen added to the S2000 were some of the hardest-working we've ever tested.
The new engine parts are simple: There's a $1500 carbon-fiber airbox that inhales cool air from in front of the radiator; a stainless-steel header ($1300) and exhaust system ($1500); an engine computer ($1500);
a low-temp thermostat ($69); and a high-pressure radiator cap ($29). The trick, according to Mugen, is managing engine heat and ignition timing. Mugen says stock S2000s dramatically retard ignition timing in response to elevated
intake-air and coolant temps — a trait the above combination of parts removes.
So equipped, the Mugen S2000 scooted to 60 mph in only 5.4 seconds, 0.4 second quicker than the stock sports car. The Mugen car outdid the stocker in nearly every acceleration parameter,
including 5-to-60 mph (6.2 seconds versus 6.8), quarter-mile (14.1 seconds at 100 mph versus 14.4 at 98 mph), and top-gear acceleration from 30 to 50 mph (9.3 seconds versus 9.8).
Only top-gear runs from 50 to 70 mph yielded no improvement. Who could have guessed 15 more horses could do so much?
