RPM's how important are they?
Original Message   Dec 21, 2010 8:40 am
OK. so reading posts, thinking (never agood idea) and just all around observing, Is a Honda machine more effective because it runs at a higher RPM?

I have the Tiny Tach on my Simplicity and it runs at about 3500-3600 unloaded and it bogs to about 3200 with a load.

Make no mistake, I have  no performance issues with it but hearing the praises and the like, does a Honda run faster, and have faster "gearing" on the impeller so the snow goes farther.

Now that the Canadian currency is so strong against the US dollar, a $3000 Honda HS724 is a hard pill to swallow.  Add in GST and PST, it's just crazy.  I'm not sure why pricing is so brutal there, especially for Honda and Toro products.  If that's the case here in the US, I'd pass on socialized medical plan.

Seems like Honda and Toro dealers in your area are not the kindest cuts.  If I was in similar market, I'd lean towards Simplicity for those kind of price discrepancy. 

However, the Toro and Honda dealers in my area decent with uniform and reasonably fair pricing, no games.

If a comparable Honda were the same &1500.00 I paid for my Simplicity, I'd probably buy one.  Even if it were a few hundred more I'd buy one.  But for more than double the price??? 

Not going to be a happening thing. 

Dealers around here demand maximum prices for everything.   Even my Simplicity would have been a good $500.00 had I bought  it in town.  As it was, I found it in a little village at a Massey Ferguson farm tractor/implement dealership.  If the tractor store can sell it for the price I paid and still make money on it, the dealer in town is obviously gouging.

Sounds like practices of under supplying the retailers that does meet not market demand and "relaxed" price control.  A bit socialist, if asked.

Why produce more if less gets you more money?  A funny concept of consumer funded subsidy.

OK.  Off my soapbox now.  :)

Canadians get gouged every way possible when it comes to large consumer products.  Automobiles for example were $10K to $20K higher priced than the same vehicle 30 miles away on the other side of the border.   When Canadians started buying from US dealers around two years ago, the Canadian dealers went ballistic.   They tried every angle possible to get the Canadian government to put an end to it.  They claimed safety issues such as speedometers not being metric, U.S. vehicles not having mandatory roll over  fuel cut out switches etc.   Since then, Canadian dealers have lowered their prices substantially.   The goose isn't laying as big a golden egg as it did three years ago. 

Some aspects of NAFTA actually work in favour of consumers.

Sorry for being off topic.

Horsepower = Torque x RPM, but Torque is not constant across the rev spectrum of an engine.

For gasoline engines, there is generally very little torque at low rpms, flat torque across the middle rpms, and then a drop off as the engine starts spinning too fast for complete combustion.

So, the short answer to your question is that the direct relationship between horsepower and torque changes the across the rpm range and the resultant horsepower curve will vary as the rpm changes.
