According to this article, and many others quoting Ford's Brian Cotter, the 302 LS as well as the Porsche 911 and M3 were the targets, not the 302 race cars.

Well, we are midway through the season, no SCCA or NASA entries that I know of. There are a handful at open track days but none at the competition level. The Z/28.R scored it's second victory this season in CTSCC last race... I put the Z/28.R in the same category as the FR500. Not really class compliant or competitive so some rules have been changed in favor of the car. The car is a Pratt-Miller prepped Camaro and is allowed an impressive 100hp advantage over the rest of the pack. The other cars run around 375hp while the Z/28.R is allowed an impressive 470hp. It's a sad affair... Congrats to the Stevenson team, not looking like a championship.

As I pointed out earlier, once a GT350 is given a z28 weight reduction treatment, it could be hundreds of pounds lighter. The GT with a similar treatment would actually be a fantastic option for competition. The z28 is pretty much as light as a 5th Gen gets, and still, it's a hefty porker at 3900lbs and close to 4100lbs race weight. That's a heavy deficit to overcome. Don't forget your roll bars/roll cages, that's gonna be another 100lbs too...

Once official weights are released, I will discuss weight a little more. Now that we can see the shear quantity of standard options, I think 3704 is a pretty good estimate. If it happens to be lower, it would surprise me. The standard GT equipment will most likely not be present on the GT350 as well as weight reduction.

In the end, I think weight will injure the z28 badly.

The next question is power and that's a big question. I have no idea what engine it will use. I say it will be a PTWA Coyote and there is no telling what it will displace. I would love a 5.5... I think the GT will settle in right around Boss numbers while a GT350 would be closer to 475hp. Maybe it's a DI PTWA 5.0 Coyote...

I recently seen an issue with a C5 members clutch failure. Failures can occur in all products, both new and old. It's kinda sad and I feel bad for Tops. He had been waiting for some time. The dealership isn't helping. I heard some Z06's had a similar issue, it won't be an issue until more pop up or someone is killed.

I hear a lot of talk pointing to a large Alpha 6th Gen. It was pointed out by a GM man on C5 that rear seats are an issue as always. It's possible that the Camaro will use the CTS's IRS...

what is another sad thing,racing has cheated,bent and broken rules for the Gigantic Mistake just so they could win races.:tsk:

Another pole and win in CTCSS. They are gradually adding weight to the Zs to even them out. Although, the damage has already been done at this point. The LS7 cannot simply be restricted like the Boss, M3, 997 and so on, it could fail. I will remind you that over restriction had failed some Boss engines before...

anyways, its easy to win races with 100 extra HP and TQ. Now at a 200lbs disadvantage, hopefully more weight is added to offset that HP advantage.

It has ruined the series... They should not be allowed to run a Pratt/Miller.racecar vs. OEM technology. Nor have a huge HP advantage...

How has a smaller restrictor failed Boss engines?

The downforce of those Z28's is impressive. In the race highlights the Camaro's are dead stable at high speeds while the BOSS drivers are working and 'dancing' the cars around more. Atleast it was nice to see two Mustangs on the podium. I think the race airs next weekend.

Not involved as much this year, but last year the Mustangs were intake restricted and weighted....I'm not current on the BOP restrictions on the Mustangs or really any of the cars this year in the new IMSA controlled series.

If the race had gone a couple more laps, I think you'd have seen a different result. The #158 Miller Mustang cut the Camaro lead down from 4 seconds to less than a second at the checkered flag, in a very short couple of minutes at the conclusion of the race. The Miller Mustang was very good, but the chase down was all THE DRIVER...Billy Johnson!

 

[Stuntman]

I don't think the BOSS has a restrictor this year and they're lighter than last year. Yet these changes still don't make the BOSS competitive with the Z28 despite the Z28 getting a restrictor and more weight (3,400lbs dry now).

The Camaro drivers are really good too and I have the feeling they were 'managing' their speed just enough to win. Everytime a Mustang got close, they'd click off a fast time or two to maintain a nice comfortable gap. They also had the fastest race laps. I still think there's more left in the Z28. Every time they get weight/restrictor, it does not slow them down.

....

In 2012 the SCCA restricted the Boss intakes to the point that they were overheating. Drivers protested and eventually boycotted the next race to protest the restrictions that caused the damage and hurt the cars competitivness.

You could very well be right.....as I'm not caught up on all the specs this year....and sometimes it seems they can change from race to race as the elusive BOP is chased by the series.

And....you're right about the drivers. This series fields some great racing talent in every entry, in every car. Still...the chase down was impressive....at least to me and my limited knowledge.

It was great to see the headwind of bad luck that had seemed to attach itself to the Miller #158 team in the early season, be replaced by some fair wind of good luck at their back in Canada. Racing is sometimes a fickle endeavor.....when teams do everything right and still don't have the results to show it, through no fault of their own. Still some good tracks and good weekends left in the season for the Miller/Multimatic teams and all the Mustangs to show their stuff.

I understand they restrict air flow. I think they were restricted to the point that they leaned out.

What's done is done, this isn't the first time major changes were made to assist the slowest cars. If it takes 100 more HP, 2 more liters, Pratt/Miller Suspension, brakes and more and Carbon Fiber panels to be competitive in an OEM class, shame on you...

The Z/28.R was not developed for CTSCC... Instead of applying themselves towards the class, they chose to apply for waivers. Simply because they didn't have the time, money, drivetrain or chassis to compete with the Boss and M3. Just do what the Challenger did and remove yourself from the embarrassment.

As it stands, the Z.28.R is now at 3500lbs with a 100lbs penalty. I specifically warned against IMSA's prejudice against the LS7 in general. Team Corvette also opted for a smaller displacement to avoid intake restrictions... Must be nice to be able to make those kind of moves without the organizing body fighting back.

the Boss 302 was equipped with a 52mm intake (90mm stock) and that in itself caused engine problems. After the protest, they went up to a 57mm (I've seen 62mm's here and there). Initially, the LS7 was allowed to use an 80mm tube (90mm stock), which they claimed brought the HP down to 470. The rest of the field is pretty much restricted by 30-40%, this results in the 350-375rwhp. I find it hard to believe a small restriction is going to have that kind of affect on the LS7.

Why can't Roush or Multimatic use their suspension components while the Camaro was waivered to use Riley components before and now Pratt components (which are likely better). It just ruins the series...

The Boss got slapped with big restrictions because it ruled the road... 6 wins in Grand Am GS in 2011 and a GTS Championship and 6 wins in SCCA. That's over half the races in each series... People cried...

The only reason people aren't bitching now is because the z28 isn't sweeping the class. Even with all this help it still in fact l@cks b$lls...

pitifully...

Forgeline wheels and some effing serious looking brakes. I think Ford is actually trying with this model. Nobody will be able to say it's just a GT with a few bolt-ons.
