I guess that would be me, and while I realize it is all quite "course and car" dependent, I would just submit some of the following empirical facts:
1. With a 200-lb passenger in my car, I seem to turn laps on the average autox course about 1 second slower than without. A 220 lb. weight decrease by our rules is an 8-point penalty. With R-compound tires, I can turn a lap over 3 seconds faster in my car than I can with street tires. The R-compounds bring a max penalty of 4 points. It seems to me our penalty for weight removal is out of whack here.
2. The GT3 weighs over 3,000 lbs., yet it seems to get around an autox or roadrace course very quickly. The ex-Kinninger car weighs more than other AM cars, but given sufficient power, it doesn't seem to suffer much, even on a short, tight, autox course.
3. At the recent SCCA Solo2 National Championships in Topeka, a competitor in D-Modified named Delmar Long added 355 lbs. of ballast to his car in between heats and ran it in the next class up (E-Modified, which is identical in ruleset but allows bigger engines at a higher weight) and went a half-second
faster, on the same course! This is in a car that weighs 1400 lbs.--where 355 lbs. is a 25% increase! This shows me that weight, even on a short course track, is not supreme--that there may be other factors involving tire grip from working harder and getting up to temp faster that may mitigate some of the advantages of lesser weight.
Seriously, I have yet to see any proposals as to how we might solve this'problem'.
Then you haven't been "reading between the lines" on my replies. Above and beyond any specifics of the update/backdate rule, or the rules for engine mods or tire size, my contention is that we have gone astray in the classification changes made over the last 3 years. This all started with the elimination of 911s from G class, to protect the 944s which were perceived as being dominated. The error that was made was in moving the 911s UP instead of moving the 944s DOWN. Our car classifications are structured from A to Q according to speed potential, with A being the slowest and Q the fastest. If 944s were slower than the G class 911s, they should have been moved DOWN in class, perhaps to E, since it seems a well-developed F class 911 is still capable of greater speed potential.
Once the 911s were moved up to H and I classes, the HM class was considered unnecessary and replaced with KM class, and former HM cars were consolidated into AM. This again was a mistake, as the H and J cars have greater speed potential when developed according to our rules, and the former F and G class 911s cannot compete with them on an even basis (for the reasons I cited earlier.) Additionally, there have been ZERO, not one single car, entered in the new KM class in the last 2 years.
My specific proposal would be to establish a new E class for the 944s currently in G, replace the 911s into G class, and restore the original AM and HM division, eliminating the useless KM class.
I have still yet to see ANY modification lists or point sheets of the cars concerned.
Well, here is my point sheet for my AM class 1973 911E:
I actually have 53 points rather than 52, as our reg form curiously no longer has the 1-point penalty for distributor recurving that still exists in the 2006 Zone 8 rules. I am unsure whether our form or the rules are innaccurate, as there was a proposal last year to eliminate this section, and I have not been able to determine if it was approved or not.
I have not run this car in our TT series for 2 years now, but I have given a great deal of thought as to how I might make it competitive again. My conclusions have been that I must convert it into a widebody and run 10 & 12" slicks, plus either install a 3.6 engine, or else spend about $7-10K in wringing more power out of the existing 3.4-liter motor. Needless to say, I have not gone this way yet, hoping for some revision of the rules.
Instead, I have invested my time in developing an FP car with which I could legally move up to GP and thouroughly brutalize the 944s running there, a completely spiteful move on my part, admittedly, born of my frustration with the rules-mongering that has taken place. My twisted logic was based on the hope that perhaps having an F class 911 move up in class and dominate the G-class 944s would demonstrate the need for moving the 944s down to a new E class, where they might progress to EP and AI instead of GP and FI.
