What you might be thinking about is the agreement between manufacturers to not make motorcycle top speeds more than 300KPH (186MPH). There are no limits on horsepower, though, and the top speeds are simply electronically limited. This also has no relation to car models.
- jimjimjim 11y agoNo, there WAS an agreement between Japanese car makers to limit the HP of their vehicles. Even the GTRs, Evos and Imprezas left the factory with approximately the the same stated HP figures. They could then be reasonably easily tuned to produce ludicrous amounts of power.
- grecy 11y agoBoth of you commenting in this chain are correct. The Japanese "gentleman's agreement" was a limit on power of 207Kw. Towards the end, many of the cars hit by this were making more than that at the wheels, let alone the crank. It was possible to gain 50Kw on certain WRXes and Evos with a different air intake and exhaust, they were so restricted. Also, for a while there was an "agreement" that sports bikes wouldn't go faster than 300km/h - they didn't limit them, the end of the speedo was 300km/h. Lots of R1s and Hyabusas will be revving somewhere in the middle of their rev range at 300km/h in top gear, then you can wind on another 4-5-6 thousand rpm, while the speedo stays pegged at 300km/h. You are, of course, going faster than that.
- snaily 11y agoYou do realize that speed and revs are linear as long as you're in the same gear? If you're "in the middle of the rev range" at 300 and double your revs, you're going to be going 600 km/h.
- grecy 11y agoSorry, you're right. I was trying to word that in a way to not say 10,000 rpm to 12,000 rpm, because all bikes rev differently. Obviously you don't double the revs, but they for sure increase
