Another question, Why aren't Y202 motors legal in CSH/CSR?

[Silas_53A]

Just curious why Y202's are not legal CSH/CSR motors, from what I was told there isn't much difference between 102/302 except ignition system. So whats so different about the 202 that make it not APBA legal?

not enough 202's were produced/imported.......legal in OSY though.......

[Silas_53A]

So maybe there is a concern that the 202 is faster then the 102/302 so if APBA made them legal the few people who actually own them would have an advantage?

[csh2z]

I have no first hand experience with them but I have heard from reliable sources that they are faster than the 102/302's. I believe it has a lighter crankshaft among other things.

When the 202 first was imported, we tested one "out of the box" and determined it was nearly 1 mph faster than the 102.

Is that a Rumor, or are they Just Saying That?

When the 202 first was imported, we tested one "out of the box" and determined it was nearly 1 mph faster than the 102.

If this means that all 202's are faster than 102's, it is interesting that 202's do not dominate OSY-400 where they are legal and have been for some time.

It is also intersting that the reasons for keeping this engine out of the C Stock Class are based upon verbal reports of testing and intuition based upon what others have 'said' but that type of analysis has been argued to be totally unacceptable with regard to engines in the D Stock Class.

Availability?

I thought that it had more to do with the availability to import the engine in sufficient qtys, and the hoops that the importer was being asked to jump through by the SORC at the time the 202 was being offered. As I recall, Ricky got tired of getting a runaround and said, '$crew this, I'll just bring in the 302 instead.'

At least that's what I remember....perhaps Ric Montoya can enlighten us to the process and how it went.

I remember Ricky telling me the same thing.

[CSR4C]

The Yamato 80 was approved at the end of its production run. Same with the 102. Ric did not submit to 202 for approval, since he wanted to get the next motor approved near the begining of its procuction, the 302.
The 202 D (long tower version) has the lighter crank. The 202D (short tower) is the same as the 302 except for the mag and the exhaust releif fitting on the tower.

by longer tower do yo mean like a standard 15" transom or some odd ball height?

[CSR4C]

The 102 & 202D have the same height tower

[DougMc]

The 202-D has the same size tower as the 102. The 202-E is shorter like the 302. The 202-D has the lighter crank and is the best of both the 102 and 302. In my personal motors the 202-D is faster than my best 102 by 1.5 mph and has a bit more punch.

[DougMc]

I was told by Stock commissioners two years ago when I tried to push to make the 202 legal in CSH that they feared an unfair advantage by legalizing the 202 and more importantly in their opinion did not want to introduce an unavailable and rare 202 motor to compete with the available 302. Many Commissioners wanted to drive CSH racers toward the 302 and eventually sunset the 102s, which may actually be a better way to go for the continued strength of CSH for many years to come.

Ed - I do not get your point about "verbal reports of testing". Does this mean you do not believe the reports. Would test data convince you? Would you believe test data that people report? Or are you just trying to muddy the waters?

actually be better? why because the 102 is faster then the 302 (out of box)? How likely is that? Aren't there WAY to many 102s running right now for the to be even close to possible? I mean, try telling someone their $3000 rebuilt 102 is no longer legal. It seems it may be a little early for that. Maybe sometime... hopefully not soon!

Maybe if they tell everyone that in 2020 or something like in ten years they wont be legal, but that will probably still be VERY hard to get by the racers.


what about that Yamato 402 or something, I thought I heard something about a Yamato 4 stoke or something... my dad was talking about it, he was reading something on the internet. Has anyone else heard of this? (I just found this on the yamato site, it still in prototype. How would APBA handle this? any chance it would be legal in any class?)
