New STL Fan

[Greg Amy]

My point is, if they're equal in ITS why would it not be so in STL?

Because your BMW has a 2.5L engine. The class limit is 2.0L

And I'm not being flippant. That is exactly, completely, 100% why you are not allowed to compete in STL. We don't really care about performance potential; we recognize it's not likely to be competitive against "true" STL cars. That's beside the point.

Would there be a large objection, based solely on the fact that it's not less than 2.0 liters, to the BMW classed as an alternate allowance similar to that of the ITS RX7 with ITS weight and prep in STL?

Yes, there would be.

Get <2.01L engine and you're in.

* Note that you are not the only one that recognizes the inconsistency about how a 13B engine is actually rated at 2.6L per the GCR. In a 2L piston-engine class. Don't bother, you're preaching to the choir on that one.

This.

That was my rambling point.

As the man (generic) said, rules are rules...until they're not.

Having driven one of the largest engines in ITA, I feel your pain. We were in the same boat. ----- We even ran ITS with the car once, but that's another story.


13B is called a 13B for a reason... 1.3L.

Can I "call" my engine 0.9L? 'Cause if that's all it takes...

(Google it.)

[Andy Bettencourt]

Correct me here Greg but common thought process:

Even though the 13B may have 1300ish cc's of actual volume it acts like a 2-stroke. So they class it effectively as 2.6L because it has twice as many power strokes per revolution as a conventional piston engine...1 power stroke per rotor every revolution whereas the CPE has 1 PS every other revolution.

By that reason, the 325's M20 normally called 2492cc motor is actually a 1247cc's because that's what it uses in one revolution of the crank, so it's STL legal then

Right!

And if one wants to get pissy about it...go read the GCR Technical Glossary definition (which I don't agree with, and tried to get corrected...)
