Limp Mode on the Track

[1320']

What is it equipped for? Why sell a performance car that can't perform longer than 20 mins?

Don't say street duty, because this car to way over engineered for street only.

The C7 Corvette is "way over engineered for street duty" also..the Gen 6 Camaro is "way over engineered for street duty".

People these days demand way more out of their cars than in days gone by.

The Tech Pack cars fit into the niche of people who want a high powered, great handling car with heated and cooled leather seats, a touchscreen infotainment system, and at a cost under $60,000. IE, a similar market to the Lexus RC-F.

And apparently can go more than 10-20 mins in a track environment without going into limp mode.

So, the C7 and Gen 6 Camaro go into limp mode in less than 20 mins on the track? Is this an industry standard? Is it common knowledge that cars without the track package can't complete a standard 3 group hpde typical 20 minute session?

The Camaro apparently not since Chevy over-built it.

The 2014 C7 Corvette with the A8 would overheat and go into limp mode after 20 minutes or less, as will a automatic Z06.

As I said before, cars now run hot. They have to mostly due to emissions and fuel economy.

What does an overheating transmission have to do with emissions and fuel economy? Last time I checked we were talking about the transmission not the engine.

Only thing anyone brought up about that was that the cats (emissions) were right next to the trans and could be causing the overheating.

If true, this is a design flaw. Why can't the cats be moved or shielded to prevent overheating?

The cause of the problem is unknown, and Ford hasn't even had a chance to address it because the sample size is too small. How about if we let the dealers and Ford look into the issue before going nuts? In addition, if you look back 8 or 10 months, you'll find that many more of the complaints about the packaging of the GT 350s were regarding seats and electronics than cooling. If I were sitting in the big seat at Ford, I would have made the rumored changes for 2017 just for the economies of manufacturing, but I think it's going overboard to assume Ford made the changes primarily to fix cooling problems on the Tech Package cars. Not every Tech buyer (including me, long before this issue came to light) made the Tech vs. Track decision based solely on the availability coolers.

WOW 25 Pages arguing in circles LOL. Ford will love this, because it gives them
time to figure it out, while people argue over what needs to be done LOL.
Talk about over heating in 10 minutes or less

All I know is....if this as happened over at the bow tie camp, we would be laughing all the way to the dealership.

It did happen in the bowtie camp, specifically the Stingray world.

I meant with their "track star" Z28/1LE Camaro

The Z28/1LEs have overheating issues or you talking about the AdM problems?

Its not just the placement, its the bottle neck they create also loads the engine more which creates more heat throughout the driveline. That and the car makes 526hp, creating all of that power means combustion of a lot of fuel, which all means heat, nothing you can do about it. All heavy high HP cars will eventually run into heat management issues at the track. Might be fluid temps, might be brakes, but at some point you will have an issue. Asking for 20+minute sessions is asking for a lot if you really consider the how much performance you are getting for the price, while the car is still a completely well mannered on the street with all of the extra crap that goes alone with being a street legal car in 2016.

And the cat theory right now is just that, at theory based off a single data point that has not been verified or substantiated in any way (ie the lethal car).

As for design flaws, I might saw we need to relax with this line of arm chair engineering. Have you seen the pictures of underside of the car? Let me know how you would have designed it. Please provide CAD models and all of the FEA simulations showing how your design would be superior from a thermal management standpoint

Ford obviously could have done better with the packages and likely should have had coolers on the tech pack cars, but I can assure you there would be folks bitching about that too, claiming they dont want to spend and extra grand or two on coolers they will never use. But to insinuate this might actually be a legal issue is absolutely insane. :lol:

Gen5 1LE and Z/28 have engine oil overheating issues.

C7 Z06 overheats everything, especially with the automatic.

The 370Z overheats engine oil.

So do many others. It's actually pretty common to require cooling mods on high HP cars for track use, since the demands are so much higher than on the street. A car that is over-engineered for street use may still be marginal for track use. Seems like the GT350 without coolers falls into that category.

I think for most people with track day experience, it isn't surprising given the power, weight, and the fact that a specific package was offered with extra cooling, and that many of us may have struggled with previous cars, or seen people struggle with temps at track days.

With that said, Ford should have just put cooling on all the versions like they are doing for 2017. They dropped the ball on the option packages, and hopefully they come out with some OEM quality cooling kits that can be retrofitted to the 2015 and 2016 cars for less than $2500 (estimating price based on the $6500 track pack option package - $2000 for mag shocks, $500 for strut brace, $1500 for spoiler, $2500 for coolers).

Or perhaps it's less than sane to accept that a car engineered and marketed the way the GT350 was would require a special version to handle more than 10-20 minutes on the track or sustain high speeds.
