Targa Miata
MIATA BUILD
January 29, 2010 - There's a huge change in the factors for 2010.
I've discussed this with the event organizers and it appears it's become public now so I can talk about it. You might remember the discussion of last year's factors. Basically, a base time is set for Class 9 Modified Large. This time is multiplied by the factor for other classes to provide the handicapping. The point is to try to make it an even race so the best team can win, regardless of car.
Naturally, it's the subject of some controversy. No Modern (roughly, 25 years old or less) car has ever won overall although it's been a lot closer than you might think a few times. Some classes seem to be more strongly penalized than others. And of course, there was the very public complaining by the Stillen team, who did not win the event - due to the quality of the navigation in my opinion. The other Targas don't try to handicap the Modern cars, and the Newfoundland organizers have been paying attention.
The end result? A few more classes in Classic, as mentioned earlier, to try to spread the field out a bit. And more fundamentally, the abolition of factors for the Modern division. Awards will still be given for the winner of each class, but given the number of classes this doesn't have a lot of meaning. There's still a 135 kmh maximum average and a 200 kmh maximum speed, so the Modern winner will be the person who can come closest to that average on every stage. The Classic division will be given their own first place award, so the race hasn't changed for the older cars at all.
The result is that Modern classes really don't matter. It's going to come down to the fastest Open Class car, and the rule book is pretty wide open. Worrying about things such as "will my 1999 head put me into Class 8, level 3 and is it worth 10 hp?" is irrelevant. Very few of the older cars are going to be competitive, it'll come down to a race between rally refugees like Subarus, Evos and the GTR with 600 hp and all wheel drive. Should be a dramatic race.
This is going to have an effect on a pretty large number of competitors. I'd say between 1/3 and 1/2 of the teams are suddenly going to be like us, completely out of the hunt because they're less than 25 years old and not equipped with the firepower of the latest supercars.
If I wanted the Targa car to be even close to competitive for a win, I'd have to do something dramatic such as install a V8. Had these rules been in place when we ran, it would have been cheaper and easier to simply stick an FM II turbo system on a stock engine instead of building up what I have. But I ended up with a pretty fun car, so no regrets there. The turbo engine wouldn't have been as operatic to drive as this one is.
It's a big change. Will it be enough to bring Stillen back? That team would have won last year under the 2010 rule set, as they expected to. Word is that Sprongl is preparing his Group B Audi to run as a 1981 classic with Level 3 preparation. Yowza.
There have been a few other tweaks. Cars with 14" or smaller stock wheels (we could do this with a different brake setup) are allowed to run R compound tires if they take a time penalty of 12 seconds/day. Race octane fuel is also allowed for 2010 only with a 10 second/day penalty. Nothing too exciting there.

So, if I was prepping the Miata for a competitive run for the win in 2010, I'd drop in one of the cammed LS3 motors we're using at Flyin' Miata. 480 horsepower and a total weight of around 2300 lbs would give it a decent turn of speed. It would be a fun (and terrifying) car to drive, but would require a fair investment. With the right driver/navigator combo, I think it would work. Unfortunately, that's unlikely to happen.
