Must read for Div II Midget racers
 

Found a very good article in a motorcycle magazine. In it they are talking about Kawasaki Vs Harley Davidson. Engines are engines>>>If you read it, and it is pretty simple reading>>>You will better understand why Esslinger came out with the Tall Head, Why Toyota and Mo-par came out with larger bores and why it is possible to achieve such high power out of the 1000cc motorcycle motor. It also helps in understanding why the 4 valve automotive motors will help save midget racing and what to look for when looking for a high performance Junk Yard Motor.

That was a very good read Bill

Went to the AMA motorcycle races on the Duquoin magic mile July 4th the Kawasaki's could outrun the Harleys down the straitaways but the Harleys could beat the Kawasaki's in the corners because the Kawis had too much power a Kawasaki did win by a photo finish awesome race and I'm not a flat track motorcycle fan!

It is pretty easy to do a drive by inspection of a motor and tell if it will be a power house or a louse. Engine builders call it the "Port window" When you look down the intake port from the outside>>>just how much of the intake valve can you see. The more valve the more power>>>that is why the displacement argument is fruitless because the real power is in the port design>>that is why a 1000cc motorcycle motor can hang with a motor more than twice its size. When I look down the port of my Kawasaki I see about 7/8th of the intake valves. How much of the intake valve do you see when looking down the port of a Focus Motor? Then an Ecotec? As old Shakespeare would say, "Thereby hangs the tail". Don't get tied up with rules that don't add up to a hill of beans. A motor 50 cubic inches smaller than another can outperform the larger one simply because of Volumetric Efficiency. Decide on a displacement representing the size of the majority of cars found in the salvage yard close to what you are racing and let the racers experiment. I would think 2500cc or 3000cc and do away with the odd ball 2436cc or whatever it is.

I'm ready for a name change "Junk Yard Midgets" that is a much easier name for us low budget racers to get our head around.;):) and we might decide yeh I might be able to afford one of them cars myself.

https://www.indianaopenwheel.com/pic...pictureid=2925 a standard esslinger port. Can't see much intake valve here?

Esslinger xl head now we can see more than 50% of the intake valve https://www.indianaopenwheel.com/pic...pictureid=2924


Stock motorcycle head now we can see darned near all of both of the intake valves. As the amount of valve or valves uncovered gets larger so does the power output per cc that the engine will produce. https://www.indianaopenwheel.com/pic...pictureid=2926

How the heck do I get pics to show in my posts?:15::14:

Click "Edit Post". Click on "Go Advanced", click on the paperclip, click on "Browse" to find your files; make sure they aren't bigger than the max size allowed (it will say in the file size column of the "Manage Attachments" window). If they are too big go open them in your photo editor program and resize, then try again.
Trust me, I'm in IT...:31:

I guess when it comes to computers as well as race cars I am just plain DUMB>>>>> Did not work for me. Were you able to see what I was trying to get across anyhow.

[ATTACH]Attachment 15241[/ATTACH]How did I do that???

That was a pretty interesting, and informative read! Thanks for posting it!! Really hoping that the idea of "Div II" or "sportsman" midgets really catches on more to help the sport grow!! All it's going to take is more people putting out this kind of information to help spread it around.

I have been racing these Midget sized race cars for 20+ years and love it. I realize that they are often entry level racers racing with us. I am old and lack the physical to do what I did, but thanks to IOW I can express my views Right or Wrong. What I am attempting to do is give racers an inside view to what is actually happening. As new racers many people are taken in by the spend your way to success>>>this is simply not true. You must think your way to success. The top Midget teams get a lot of stuff more or less given to them, by doing this manufactures hope the other racers will follow the example of the guys out front and race with their products and is often the case.

We race for fun and the challenge of out thinking the other racers. Sometimes we are Hero's and much more times we are Zero's (It is that Hero thing that is addictive). If I can convince the newer racers that you don't have to use all of your kids shoe money to race on and be successful and convince the organizers to keep all the racers into account and forget about the Manufactures with all of their incentives then maybe I have done something to help Midget racing.

I agree with you 100%!! I've seen guys do a lot with very little. All it takes is the time to do the research in what your doing. Some years back I watched Dean Hoffman out here in Illinois beat guys in the A-Mod division with well built big v-8's using a little v-6 motor! That wasn't but maybe 15 years ago. I like the idea of the DivII style cars personally. Brings back that concept of doing the research in what junk yard motors to use instead of slapping a checkbook down saying "just build the biggest & fastest!" With BAM I've seen a lot of ingenious stuff going into the cars. One guy has a magnito powering his Ecotec, and we have another running a 750cc motor AND keeping pace with everyone else! That's the kind of stuff that draws me to it. That and doing the junk yard crawl.....
