That's an odd statement. I've been driving high-reving fours (among other things) for nearly 40 years now, and I've *always* run my little motors to the redline on a regular basis. Except for Triumph cars this has NEVER caused any problems or shortened the life of my engines (and I've put over 100,000 miles on several cars). There are lots of ways to abuse a car or motor, but reving it through the rev range it's designed to be used in does absolutely no harm at all.

Also, the CF reinforced blocks are (as far as I'm aware) unique to Honda, and a key to making the F20C live at 9k. Knowledge and pride are two entirely differen things, are they not? Fact is, I had a 9k car way back in 1978. Back then it *was* something I was proud of, but today produciton cars can do it, so it's no longer any big deal. Bikes rev even higher, and don't have reliability problems as a result. Isn't it fair to say that ANY well designed engine can be operated at it's design limits without exceeding the design intent?

 

The F20C/F22C has abbreviated piston skirts, which are good for high RPM operation, but not so good if the motor is lugged. Under load there is likely to be more wear at low revs (2,500) than at higher revs (above 5,500). These motors are not like some American V-8's with inflated redlines where trying to run at the redline long term is apt to make the motor consume itself. They're far more like Benz motors, which are designed to run flat out on the Autobahn all day long.

 

I don't know if they are unique to Honda, but I don't know who else has them.

Also, it is not true carbon fiber, it is a carbon and aluminum fiber mixture.

The FRM cylinder liners are much slicker than the iron used by others. The slickness helps in generating less heat AND in preventing wear. That definitely helps with longetivity at high piston speeds.

[QUOTE=Intrepid175,Dec 10 2005, 05:03 PM]Ok!

 

[QUOTE=RED MX5,Dec 10 2005, 05:20 PM]
(2 * 6.62")/Rev * 9000 Revs/Min = 119,160"/Min = 165.5 ft./sec.

(2 * 7.14")/Rev * 8000 Revs/Min = 114,240"/Min = 158.7 ft./sec.

Somebody check my math; not my strong point.

 

[QUOTE=Intrepid175,Dec 10 2005, 11:44 PM]You had the right idea but you grabbed the wrong numbers off my post.

 

no, honda will not warranty a new S2000 with a comptech supercharger.

Some of the dealers will warranty it, but not Honda officially.

 

Honda does allow certification of used S2000's with Comptech superchargers. If they don't allow it, how do the dealers certify the cars?
