C7 zo6 vs 2014 comp m5 on the track. Oh boy.

[Sergm3]

I was on the track this weekend at big willow. Two owners show up with new zo6s . I was really considering the car for new new track toy, because m5 is not a real track car we all know that. I joined the corvette forum two months back just to read up on the car to make my mind if I want the zo6 on that later. Talked two the owners one saying his engine was replaced at 53 miles because piston went through the block. He is going to take it easy his first time out on the track. Second one also first time out just want to see how the car does. I'm excited to see them on the track and make up my mind. Temps are in the high 90 and reading the corvette forum this car has major cooling problems if you track it above 70 temps.

So finaly how m5 does vs zo6 it run all day long with ac on cooling seats on best time was 1:43 corvette zo6 heater on zo7 package guy get 1:54 second guy 1:58 both overheated both went home after their car didn't finish one session. If you're like me and was considering new zo6 for your track days don't cooling on the car is garbage. I know some of you might say why track the car when it's 100 outside. To you I say why not.

As for the corvette forum. I posted thread on it got owners ho don't track the car telling me they don't overheat because they drive on the street . Others that track want GM to fix the cooling system because they can't track the car . And today they banned me from the forum because they don't want the rest of world to find out that new z06 has major cooling problems.

If you considering zo6 don't until the GM fixes the problem on this car. Just my rant for the day.

I tracked my Z07 this past weekend at MAM. I started off in the Intermediate group on Saturday as I hadn't been to the track in about 5 years. After two runs I was encouraged to move up to the Advanced group, where I've always run in the past. This was a BMW CCA event. I ran five sessions, in the morning each one 25 minutes and in the afternoon they were shortened to 20 minutes. The ambient temp was mid to high 80's. My car is a Z07 package car with the A8 transmission.

In both run groups over both days I had no overheating issues; not one. The car ran the full session every time and I could have kept going for far longer than 25 minutes. I only ran the car in Manual mode, and short shifted; generally never allowing the car to rev past 5500 rpm. Not one car passed me all weekend in my run groups; not one, not even close.

The car can be driven for a full run session at an HPDE as long as you drive the car via its momentus torque of about 570 ft lbs from around 1750-5500 rpm, and it is by keeping the revs down that the temps stay in check.

Granted the car needs a secondary engine oil cooler, but driven as above, you can have great fun and be extremely fast.

The z06 forum would love to hear this info. Read up how great zo6 on the track. The information gets dismissed by people like you. The I've seen it with my own eyes how it drives on the track in hot weather.

This reminds me of the vid of the ZR1 drag racing the X5M.

The M5 is a fantastic car. The cooling system is adequate for track use even in hotter climates in the summer. It's a sweet package overall.

The M5, however, is not even in the same league as the Z06 with respect to lap times (assuming remotely equal drivers). There is just no comparison.

LOL... First world problem... I got banned from M3/M4 forum last year because my M6 is faster than KING

I agree with you 100% That's why I wanted zo6 for my track toy. The laps at big willow with professional driver was 1:21 and the guy run 1:53 not pushing the car and it overheated. The car is great, but it can't run on the hot days on the track. Miatas and civics run all day not overheat. I'm only saying the cooling system on the zo6 is a joke and nobody on the corvette forum talking to GM about it.

[FASTTOYS]

Own both cars & the 2015 Z06 is faster on the track with equal drivers all day long, mine is a M7. I Live in HOT Texas and have no overheating issues on the track. I Love my daily driver M5. I have owned 17 BMW with 8 being M cars. I am not a GM fan, the interior still sucks compared to German & Italian cars. I only purchased the Z06 because its the last High performance two seat sports car north of 500HP that you can buy with a manual transmission. I know PDK, Auto & DSG are faster on the track. Their is nothing more challenging than pounding through the gears on a race track.

IMO GM rushed the Z06 to market and will resolve the issues with the 2016 model. I know no one on this forum had any issues with their 2013 M5

I don't see Dave's post as dismissive but instead factual based on his results in his own eyes and how it drives. We all know there are many more opinions and results than just the one's we read here so its nice to hear someone who had/has a positive experience.

(this is no way is being dismissive as Im sure there are heating issues)

[jvise]

I own both in sunny AZ and have had no overheating issues.... Yet.

[URBAN LEGEND]

Proof of this thread.

[Sergm3]

I'm talking about tracking zo6 in hot weather. Driving speed limit on the street and not overheat any modern car should do that with no problems.

[URBAN LEGEND]

That's why I left that car alone. Went ahead and picked up a Z/28 until this gets sorted out.

I don't want to be a guinea pig for GM.

Just like most issues, the various forums tend to exaggerate the effects.

What were they're peak oil temps? The PDR will export a log containing oil temps and every other parameter you may want in a situation like this.

BTW... Please post a video!

Peak temps on my car? Or video of zo6 owner going home early?

[thebishman]

So just to prove that the car can indeed be driven in mid to high 80 dF temps for a full run session, and actually be driven pretty damn fast, even though I was short shifting to control temps:

That's a popular track car, not too expensive but lot's of fun. Can't keep up with the 991TTS though and one guy did leave due to overheating his. It also doesn't have tow hooks built in which you need for the track. If you watch my video you can hear the instructor saying Z28 on your neck when I am coming out of turn 8 and I gun it through 9&10 reaching 120 on the stretch before the hairpin at 11 and then lose him entirely on the back stretch. He came up afterward and complimented my car, nice guy, he said he was trying hard to overtake me but just couldn't do it unless I was coasting, if I pushed it, he couldn't take me.

So this is a stock z06 getting pulled on VERY hard by a FBO nismo with pump gas.. And has a confirmed hp of 650-680whp on a dynojet...

Not too many cars can keep up with the higher end 911s.

Wasn't even close.

[thebishman]

Can someone please explain to me the point of running a stock vehicle against a highly modified one? It proves nothing!

It's 335iRlz justifying his GTR buy again- I had that car 6 years ago and it was fast but who cares. I have no doubt the Z06 crushes it stock
