GT350 vs. Z/28

[Nasty99z28]

The Voodo is far more advanced than the ls7. Ford released info stating that the GT350R will make more hp than the standard GT350. I wonder what the hp difference is?

Well besides the ohv vs DOHC it should be much more advanced. The ls7 is a very old engine. As for the "R" having more power that shouldn't be a hard or a surprise. Probably 10-15hp more which is easy to gain.

Other thing I do not understand is why GM is insisting on using a 23 year old technology OHV engine, insted of moving on to a newer DOHC platform. The earlier they do it, the better for them, because if they are just going to keep on modernising the OHV, they're going to reach a point where it will not be modernisible enough to stay on par with competition.

Thr issue is OHV motors are "cheaper", typically more compact and are sometimes lighter.

Sometimes.

A big issue is they've gone to DI with no apparent solution to valve coking

IMHO I really don't care what's under the hood as long as it's light weight, makes good power and has decent mpg. How it's made or what type doesn't bother me because I don't race it and I'm sure 90%+ here on forums don't race there's either. I just want something that puts a huge grin on my face when I hear it rumble and mash the gas.

By hook or by crook, Stevenson will win the Championship.

It's too dangerous to race in the rain yet it's a Pit Penalty if you use your vehicle as a weapon for track position.

Stevenson, your car sucks and at one time, I thought you deserved a Championship. Not inherited but a chance to be champions. Not so much now...

If you can't beat 'em, take them out of the race. That was the title picture IMSA just let Stevenson walk away with... other than the rule changes and sudden stop of a race...

So are you saying that with the Stevenson car running away from the GT350s for the first half of the race, it will be the GT350s that will get another BOP adjustment? Naw, that couldn't happen. Could it?

Never mine the fact that the ls7 is 1.8 liters larger in displacement.............428 cubes verses 315?..........:ford:

It has become so overly apparent that IMSA/NASCAR is pushing for a Stevenson championship.

I think everyone recalls my displeasure when IMSA announced the z28 right? It was such a far fetched concept to think that a single car could destroy a class... actually, I retract that statement... TWO vehicles destroyed the class...


First, the z28... Both the first and final blow in my opinion. It was over January 2014... The rule changes, waivers and exemptions were far worse than the GS.R.


Secondly, the GT350... It was HIGHLY over-engineered for the class. I don't care if it's the cheapest car in the class. It is way above and beyond what should be permitted...


If the class is evolving or being absorbed, fine... If it's just chaos until nobody shows up? I'm done caring... Fun to watch but can't get emotionally involved...

(Same as NFL, NHL, UFC, any Boxing, NASCAR)

I'd been hitting 80 before the dog leg all weekend. I probably lost it around 60 at the end. Something broke I'm sure, I heard dragging for sure. The rear end was back and forth (broken rear sway bar) and even the slightest turn of the wheel the rear slapped back and forth. I hit the barrier halfway through I think. The car was towed.

The Dr. said my helmet hit the roof loop above the glovebox! I had marks on my helmet and the tube was marked too. We didn't pad the tube because we didn't know. I had no idea my head would hit there. I was KO'd but was trying to unbuckle myself. They said my straps were loose. Even after tightening them every free hand I get (not as much as the driver should had).

I'm fine, the car is gone. Need to find another one.

Besides the power output of the Voodoo, are there other parts of the GT350 that make you think it is over-engineered for the class and puts it beyond the reach of the Nissans, Porsches, and BMWs? What specific rules does it violate or overstep, besides HP?

Other than a mechanical advantage, the power band eliminates shift points. The Porsche also carries this advantage but is mitigated somewhat by its output.

I imagine the RWHP limit is exceeded, it's more than likely 20hp stronger than the LS7 and has a 4000RPM power band.


The GT350 is a GT car... It's literally right in the name ;)

I say bring the Coyote GT to CTSC. It's all they need.

Anyone that followed racing from 1999 to 2012 should remember ALMS GT1. The class was super competitive... until Chevy decided they needed an LS7... Not just any LS7 either, a Pratt and Miller, 580hp LS7.R. Pratt also built the C6.R (or Z06.R) because Chevy just couldn't compete with the Vipers V10.

Well, teams were already unhappy. Aston pulled out, Viper left production and changed focus right before... Eventually, the two Z06's were the ONLY two cars running... They won the Championship again that year. They just kept racing and winning...

What did Chevy do? They made a 2009 Corvette Championship Edition to commemorate their success in GT1. A class they pretty much destroyed with their whining and rule bending. They even celebrated the Corvettes first 24 hours of Le Mans win like they did something special. The Pratt Corvettes were the only ones running...

CTSC GS won't last much longer...

Having ZL1 and Z/28 at the same time never made sense to me, they are alike ( more apparent differences are: one is 6.2 with Supercharger, other 7.0 N/A, both are track oriented, other than that just prices and some appearance cues are different). The way I look at it, it would be much more logical to blend both into a single car under the name of ZL1 or Z/28 and give it a 60-65k price tag, and the GT350 contender is there. Not only it would take much less developement time and money, but also the car it self would be much more content, rather than having 2 cars that are more similar than different, now if Z/28 had been a more aggressive version of the ZL1, than it would be fine, but the way Chevy treats them, it is not so apparent.

GM's engineering remains a world leader. Product planning however leaves allot to be desired. Why is there a CTS and ATS, both of which barely equal the sales of the previous CTS? They introduce a mid size truck when they have no plan for light duty vans, besides re-badging a horrid little Nissan. They think that by using Camaro design cues on the '16 Malibu they will have a winner - is that doubling down? The current Malibu with its Camaro tailights/arse is such a smash hit?

Now they want to add an SUV between the Equinox and Traverse. The next Equinox will be smaller and add a different third row SUV below the Traverse. They already have the small Trax, why not add a third row to the next gen Equinox (which is already a bit bigger than its peers)? Odd.

I like the looks of the current Silverado, but don't fly in a plane if you believe their hype about steel bodies!

Sometimes I don't get their product placement strategy. Another example is Spark and Sonic. Sonic is slightly larger than Spark (on a side the 2016 Spark looks larger than the 2015 Spark but there is no official info yet, so they might be even equal in size) and has a sedan with a trunk, but that's where the big differences end. Other than that they are both city cars, Sonic being 2k more expensive than the Spark. And why do they need two very similar cars intended for mainly city use?

I wonder what Chevy will say about the Aluminum Body PU they are working on for 17-18 when it debuts. Our Aluminum is more Aluminum than Ford's?
