Correction to 5/09 Fastrack

[JoshS]

As you all probably noticed, the 305ci Camaro/Firebird and the 5.0L Mustangs were added to ITR in the latest Fastrack. However, they were published with incorrect weight listings.

Please refer to this post on the SCCA.com forums for the correction:

The news gets better and better. I think these weights will make sure that there will not be many of these hitting the track. I would need to put approximately 400 pounds of ballast on a Fox body that has the same engine as the SN95. I would imagine the crappy brakes may just catch on fire at faster tracks with hard braking with all of the help that the rear drums will provide. At least the Camaro is already a heavy car.

You cannot be serious!! Would someone care to explain the math?

this is for real right?

It's for real.

All the research that was submitted (which was plentiful), and then our due-diligence research following, agrees that 30% power gains are possible. Then, the cars get a +150 lb torque adder, far and away the largest torque in the class (for reference, these cars have 300 ft-lbs, the next highest cars have 225 ft-lbs).

However, they get some breaks too ... -50 for the live axle, the Mustangs get -50 for brakes too.

What Josh said.

This decision took a long time partly because we spent a lot of time digging around, to try to get the best evidence available. This was a potentially controversial move and we needed to be as confident as possible that we got it right the first time.

What is the logic behind the weight differences between the 94-95 Mustang (SN95) and the 89-93 Mustang (FOX)? The FOX has a disk/drum brake settup, is narrower (harder to fit wide tires), and has less aero that the SN95. I would think that at a minimum the FOX should get a more of a break based on these items. In my opinion It should be the lighter of the two - this is how the cars are handled in AS.

Either way, it will be interesting to see these cars on track.

Let's look at it this way. This is somewhat of a controversial move to introduce a V-8 into ITR, especially given the fact that this is an IT growth class. The cars that are classed have the potential to be very expensive builds (ask Phillips what he could POTENTIALLY spend on that 968). If you're going to class a V-8 Camaro (that is the width of a tank) the weight better be set at a level that makes it a little challenging in peoples minds. Otherwise it will be unstoppable and ruin a fledgling class. The formula for making power in these american v-8's is very known....you can get the recipe in the magazine section of Stop & Shop. I think the cars need to be heavy at least initailly to see how it shakes out. I think cars like this will be very tough to beat at tracks like Road Atlanta.

Make all the Mustangs the same weight at least , they are the same engine specs.

If they are the same engine specs why does one have 10+ HP? Headers, ECU?

Couple of points: The 'recipe' for power in these cars ALWAYS includes a high-performance intake manifold, a new cam and uprated air-metering device - all of which must remain stock in IT. In doing our research, when these engine builders heard those limitations, they hope for huge power gains. Torque will be the factor on how they perform IMHO because handling and braking will be way below class averages me thinks...

No Andy, that's the formula for making CRAZY power from these engines!!

I can just picture getting held up in all the corners by an ITR Camaro then getting blown away on the straights in a drag race.

Here's a dumb question... I've been out for a number of years... What happened to the A sedan class? Still around? if so, classing v8s in IT doesn't make sense

[JeffYoung]

Still around, but that ruleset is ENTIRELY different, and much more open.

We've heard the "we don't need ponies in ITR because of AS" argument and, without trying to sound argumentative, I think that makes as much sense as saying we don't need IT because many of the same cars are classed in prod. There is that much difference in the rulesets.

Exactly. I'll I'll bet inside of four years there will be more Pony cars running in ITR than in AS, at least in the SE.

Maybe, but I bet the v6 cars end up being more abundant and attractive candidates.

Be that as ir may, as long as people are running them it's all good. The way i see it, it really doesn't hurt to have any car classed as long as its empirical properties fit the structure of the category and the class.

I submit as an example of such thinking: The Triumph TR8. I think we all agree we're glad that car got classed, even though it's rather atypical.

It is around. Why would these cars in IT not make sense? Different prep levels. MANY cars are classed in IT and Prod, GT, etc.
