You are wrong because nobody has said this yet,How much horsepower does it take to move the car or truck or anything you are trying to move?It never took 450 horsepower to move a tractor trailer.In the 1960s they had 180 horspower diesel engines,even smaller before that, in tractor trailers running 70 MPH.No turbo,and lots of gears,even 3 speed rear ends.A 13 speed transmission with 3 speed rear ends is 39 speeds. A VW doesnt have a lot of horsepower,maybe 20 hp on the old air cooled ones,and they would go 70 or 80 mph. In an ideal situation,you want enough horsepower to move you quickly,and a VW with 20 horsepower will move it alright.Say you rigged up a 5 horsepower motor with a lot of gears and you can still move the VW at 70 MPH on flat ground,it might take 3 or 4 time as long to get it there. In the extreme example I gave about moving 80,000 pounds at 70 MPH on flat ground with a 15 horsepower motor,I even said that getting it started was what was hard.Plus Ill even say this,you just pull out the 450 horse power engine and put the 15 horsepoer rig in,but with another transmission hooked to the truck transmissin.The little motor will only put out so much power,but how do gears effect the power the engine puts out?There is underdrive as well as over drive.You would need torque multiplying gears,like my example of the wrench to get the truck transmission turning,but it can be done.So say the 15 horse engine puts out 10 ft pounds of torque,then you put it through an underdrive set of gears to put 100 ft pounds of torque on the transmission of the truck input shaft.Smarter people than me can figure out what gears it would take and how much would be lost to friction,but its possible.I dont care if it takes 3 hours or even all day to do it,Im saying it can be done.It would be too slow to be practical to use.
One time I ran out of fuel before I got to the top of the ramp with a fully loaded semi.In order to coast down into a gas station I pout the truck in gear,cranked the starter and the starter pulled the whole truck up the hill,around the corner and got it started coasting into the station.Not fast of course,but faster than you think.How many horse power does a starter motor have?I bet its not close to 15 horsepower.
Some of you all are handicapped by what you think you know.You have book learnin but no practical knowledge.Every discussion always has nay sayers,but some of you all,even sounding as if your argument has merit,dont know what you are talking about.Gears are how everything is done.Look at a tractor,its not fast,but it will pull a house down.Why?Gears.Gears work the other way too,which is why cars can go 150 MPH if you believe it or not?Just watch Nascar,they go over 180 now and did go 200.Did you know that in the beginning of Nascar up into the 1960s,they went and got a stock car without an engine and transmission and made a race car with it?If gears wont make a car fly,and solid lifter cams wont make an engine scream,you all better tell Nascar,but I dont think they will listen.This is really kid stuff.I grew up with kids that knew this stuff 40 years ago,and here you all are,being defeated by your own knowledge,or lack of knowledge. So here is a question for you,when does my 15 horsepower motor not have enough horsepower to move the truck with enough gears?Can gears increase the torque put out by an engine? There is always more than one way to skin a cat.Plus there are guys here who just post to run their mouth as if they know something,or to stir up trouble.You can figure out who.They never help any conversation,and drive off people who might have good replys.Just dont pay attention to them if you want to reply.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
