Dave, there have been a ton of good points raised here in the 330 plus posts...
We've covered:
-differences in dynos, both manufacturer and location.
-differences in cars...some ARE weaker right out of the box
-differences in prep levels
-differences in the same car at different tracks, vis a vis the other cars
-a variety of data, some conflicting, some rather consistant.
We should be able to draw some conclusions-
1- the class "target" is the RX-7/Zcar. That is to say, (and lets not get hung up in definitions TOO much here) on an average track, the physical properties of the 7 and the Z, will yeild, when well prepped and well driven, the benchmark in terms of performance. On some tracks certain cars with different characteristics will be stronger, and so on. That is the nature of racing cars with varying configurations. Ideally, it all averages out.
2- there is a process that is in use to equate the physical characteristics of varying models and align them with the class targets. This is true for all 4 classes. It takes into account a variety of chacteristics, not limited to the type, and spec of engine, suspension, brakes, weight and balance, and so on. The numbers that the process yields along the way are constantly "reality checked" by a panel of 9 guys, who draw upon experts in the various marque areas as further reality checks.
3- if you read between the lines you can see that the ITAC is doing work on many cars in all the classes, and this may come to light in the future, if the boards decree it. We make recommendations, they enact. Any car that is seen as not fitting the model has gotten a double take. We use the car names to ID them, but thats it, we don't care if it's a BMW or a Borgward.
4-Finally, it is very evident that the BMW needs a double take...it doesn't fit the target as it is.
Some pertinant BMW points-
1- the car is widley known to be conservatively rated hp-wise.
2- it has many desirable traits as a race car.
-great suspension
-great brakes
-great engine, both in front of the pack torque and power
-great balance
Plus, a wealth of support from a variety of sources, and the lack of an Achilles heel.
3- we've heard many hp claims, but throwing out the highs, and the lows, and concentrating on repeated submissions by a variety of sources, it is safe to say that 210 at the wheels is very viable. (Dynojet) With tq in the 200 range.
If you take this as acceptable.....( and really, we can debate that these are "fabricated" numbers all day long, but as we have been requested to keep the sources to ourselves, that's pointless), you see the dilema we are in. (Interestingly, some of the numbers have come from unbiased third parties not in the class)
Leaving a car with a physical superiority alone is not in the best interests of the class at large, nor the people who have been marginalized by the cars inclusion.
Now, you have been better in some respects than some of your fellow BMW champions in looking at the big picture, but on the other hand, you do, as you point out, come across rather acidly in text. To the former, I direct this:
As you pointed out, you can NOT deny it is an overdog.
So, what do you suggest?
To the larger reading body, I am amazed that nobody has mounted either: a serious rebuttal, with expert testimony, etc., or has decided to work with the system to minimize the "damage" and resolve the issue in a way to serve their interests.
Largely, but not entirely, the feeling I get from this, and from previous threads is that the BMWs are entitled to their overdog position, and that the club shouldn't be raining on the parade.....and doing so in any way constitutes a "witch hunt"..
If it were me, I'd be thankingmy lucky stars for my fun few years in the sun, and I'd be trying to minimize the damage by working to an equitable solution. But then, I've never liked denying the obvious either....
