SORC Please Consider "Parity"

[PittmanRacing]

Yes, check with Andy Hanson and see if he would be willing to share. No doubt he also has a good OMC to compare with as well.

They were 102's accordingto inspection I was at.

Kyle - Maybe you should check the pictures. Picture numbers 6, 250,and 254

You can dyno motors all day long and all it will show is power curve and horse power which means nothing with what we do. A motor may put out 10 more horse power then another but with a much smaller power curve and you keep it in the power curve or its a dog. To keep it in the power curve you add more gears in a transmission which we dont have in and outboard. How close do you think you can get different make motors close to each other then they are right now. All you are doing is looking at one or two races and coming to a conclusion

[rumleyfips]

That sort of silliness is the reason I don't believe anything said about the Sidewinder. As everybody knows dyno's are useless and neither Ferarri nor Hendrick own one: and they have transmissions.

Lots of boatracers have used a test wheel and a tack. This is nothing like a dyno which loads an engine with a water break and records the rpm - oh wait a minute.

We have all heard the cries of super OMC A's built by sorcerers who got their knowledge at the crossroads. How can this be true if a more horsepower can lose you a race?

Doesn't Ron Hill think of propellers as gears, able to compensate for different torque curves?

Smoke and mirrors. If the OMC's are faster than the Sidewinder, why this distraction.

I wont lower myself to respond to your post John.

Great Classes

If we put all 11'6" boats in one class we lose revenue at races
unless, as suggested, there are multiple heats. I region 1, as we all
know by now mostly the same boats run two classes. In addition
heavy or light drivers lose a class that is more appropriate to them.
25ssR is a great class as is why change it ?

25SSR and CSR are great classes. But we dilute the participation in..... and at some events it is all of the same drivers in both.

Ummmm Type in Hedrick Motorsports Dyno.... and Yes you will see there dyno on video http://www.youtube.com/watch?v=Is4AgjuWEPo

George:

As your reply was noncommital, I should clarify the sources that helped form my conclusion. Most of them are from Boat Racing Facts and are easy to find. Some are accessable using Google.

In the mid 50's, Mercury ran dyno tets on the B Hot Rod and the 20H. The results were used in the development of the 20H conversion package.

A 22 ci. OMC experimental engine was dynoed at the factory at 50hp in the 70's.

OMC dynoed a Koenig to compare a developmental snowmobile engine.

Wayne Balbwin has posted pictures of Dieter Koenig working at the factory dyno, developing a motorcycle engine. Wayne also shared pages from his notebook about that day.

There's a neat story about working off a hangover ( not Wayne's) in the Koenig dyno room.

Paul Christner has published dyno sheets from the Quincy facility. This is from memory and may be faulty, but 55 years ago, Quincy and Hubble built stock engines and provided before and after dyno sheets.

Frank Volker speaks to the usefullness of the dyno in looper development.

Some outboard shops have their own dynos and routinely test customers engines ( AIM, Ottawa).

It seems that outboard manufacturers as well as specialty builder have found dyno'd useful for development as well as comparison testing of competitor's engines for more than half a century.

Since some , involved in the development of the Sidewinder, are known for building fast Mercury's and OMC's it should be a cheap easy job to dyno all three. If I had spent a box of money and 5 years developing a racing engine , I would certainly have compared it to the competition both on the water and on the dyno.

Charlie P is correct.

Mike, Congrats for your HOC induction. Sorry I’m going to miss it. Couldn't happen for a nicer guy. It’s well deserved.

What's wrong with that?? Really??

Huh?

Why are you beating your head on the wall? It is a different way of looking at things. Outside of Region 6 we have diluted both 25SSR and CSR fields. We have had weekends when we do not have enough of either to make a race.

We can agree to disagree.

[Racerkyle20]

No class changes are happening this year in stock. No consolidation of classes were on the agenda in Texas. The sidewinder is still a legal A class motor. Furthermore an A class parity committee has been created by the SORC. Those members are:

Howard Pickerall (merc)
Rich Runne (SW)
Brian Trolian (OMC)
Kyle Bahl (not affiliated in class)

We will be working on trying to provide a fair way to make the A motors work well together.

Also the 20SW motor has been added into the B class (still a legal motor in 20ssh, 25ssr, 25xh). A parity committee will be created for this as well. More to come.

And mike....I guess I need my 302 to go faster Congrats!
