October 21, 2009 - The 2010-14 regulations are available.
The rules are kept mostly static for five years at a time, allowing people like me to delay their Targa adventures without fear their classes will be moved out from underneath them. 2010 is time for the new rule set, and there are a few changes.
Some were expected, such as a minimum tire wear of 140. This is the same as "street tire" autocross classes, and there's quite a tire war going on in this category right now. They're not much cheaper than full-on R compound tires, but they also don't stick as well. I believe this is an attempt to slow the cars down.
Pump gas will also be required. Not a concern for me - we ran that way last year - but some past competitors have complained about problems with contaminated fuel. You're still allowed to carry your own fuel but can no longer refuel outside specified service stops.
Now we get into the interesting stuff. As expected with the fuss about handicapping and "modern cars can't win", there have been some changes. One simple one is the splitting of Modern and Classic Divisions. The organizers will essentially view the event as two races. Three, really, as Open also gets a separate win. Will this keep people from viewing the car with the lowest penalty points as the overall winner? No. But it's a good effort.
The various Categories have also been shuffled around. The year breaks for different classes have been moved a bit. Class 2 (up to 1961) is gone, merged with Class 3. A new Category has been added between ours (the old Category 8) and the newest, ranging from 1998-2004. Open used to be Category 1, now it's 0. The net effect is that we're in the same grouping of cars as before, but we're now the fourth-fastest category instead of third-fastest. Our category would be 6 in the new numbering scheme.
One of my suggestions had been to rework the rules between Standard and Modified, to make it more clear when a vintage car had been hugely modified and should run in a faster category. And the Targa organizers did something similar. Instead of just Standard and Modified, there is now Level 1, Level 2 and Level 3. On my first reading, it looks as if we'd land in Level 2 - and only barely! That category is only allowed a 10% displacement increase from stock, which means we'd be allowed to go up to 2023cc. Our engine is 2020cc. Whew! I'll have to go through the rest of the specs to be sure, but that seems to be the case.
Minimum weights have gone up. We used to be allowed a 10% weight loss from the factory curb weight, now we have to match it. Level 3 is allowed a 100 lb weight loss. This means we have to pork the car up to 2293 lbs. That's in "as raced" condition, so it would include tools and a spare. Honestly, that may not be far off what we eventually had.
There are some minutae as well, such as the method of adjusting displacement for things like overhead cams, four-valve heads and the like.
Hmm, it looks like my use of a 1999 cylinder head would bump me into Level 3. That's not good. It looks as if the big difference in engines in Level 2 and Level 3 are 10% displacement and the ability to change the number of camshafts and valves. If you have an old crossflow Ford and stuff a twin-cam Lotus head on top, this is for you. If you want to add a four-link suspension to your old Escort, same deal. But for those of us who already have four valve twin cam engines and good dual-wishbone suspensions, it's not dramatically different. Would it be worth dropping back to an earlier head to stay out of Level 3? Probably. Some dyno time would tell.
Or I could stick with my current plan of stuffing a V8 in there, running Open and scaring myself silly.
