[MBZ] Re: Top speed in what gear?
Not at all uncommon at all. In a relatively low-powered engine, a higher gear can put you too far off the power peak to overcome wind resistance and other running friction at higher speeds, so you can achieve a higher speed in a lower gear. Downhill or in a stiff tailwind, you may be able to exceed the lower gear's top speed, but not on the level. Dan What? You're saying that your car has a higher top end in 4th than it does in 5th? Unless there is a governor attached to overdrive, that is totally counter intuitive.

Re: [MBZ] Re: Top speed in what gear?
You are talking about my first car, a 1956 36 hp VW that someone put 6.50 15s on the back. Uphill in 3rd, downhill in 4th. At 08:54 PM 7/14/2005, you wrote: Not at all uncommon at all.

You can't beat my BMW Isetta though for proving there is always an exception. It overrevs if you try to exceed 38-40 MPH in 3rd gear. 4th (top gear) will take you to 54 mph. It matches your criteria, low power, 298 cc, 13 hp. If you've seen a rolling egg you know about wind resistance. I think the majority of the time you see the phenomena beign talked about is when overdrive is involved. The drive train is geared to run up to to 1:1 ratio and then when you engage OD it is for economy not speed.

Re: [MBZ] Re: Top speed in what gear?
yes, or poor engineering. In the case of my VW, the oversize rear tires acted as an overdrive. Had it been left per Dr. Porshe's design, it would have run out to a better top speed. However, being broke and cheap, I left on the oversize tires and imagined i was saving money by lowering engine RPM/road speed.
