What's up guys? I had a question as to which driving mode selection is the best if you were going to be doing a highway run, maybe 60 to 160? Sport, track, ect ect? I still haven't quite mastered which is which in most of the modes and was curious as if to it matters? Thanks so much!

Huh???????????? are you kidding???????? Touring mode...................

I'd use Track/Race on a runway. Beware though, you don't have any nannies protecting you except for some very mild performance traction control.

What country are you in that you can do 160 on a highway?
MPH or KPH?

I would think Sport Mode for highway pulls as it gives you the aggressive throttle response you want and keeps you in the higher rpms and keeps the nannies on just in case but I'm not 100% sure if this would be the quickest setting so wanna see what others say as well. I don't typically engage track mode for anything but twistys.

rwheelz

There is some misinformation here. The car has the nannies in place even if you select track mode.

Denstoy968

This is true. The only mode that turns off all nannies is when in PTM mode 5. But I wonder....is there an advantage of a straight line highway roll being in track mode vs sport mode??

Edit: NM see other stuff.

I thought track/race mode would be the least invasive on power as well, but didn't find that to be the case at the track this past weekend. I never found a mode or combo that didn't pull power at some point during auto X , speed stop or road course. I did find at what temp the brake fluid boiled at. I didn't think not running the crap out of it would be OK, but even not pushing it very hard it still was a problem. Live and learn. I just didn't expect it at the power that I was keeping it down to.

Hmm couldn't find many threads about highway races except this one, I was wondering from 75mph to 120mph or so the starting rpm is pretty low, like 3k. And downshift you can't do it coz 2nd gear you don't want to downshift to 2nd, when speed is above 67mph according to the manual. So would you say 75mph to 120 is the weak point of Z06 vs other speeds? Highway speed limit here is around 65 and people drive 70 or so. That's how I come up with 75mph to 120.

What speeds at highway is more advantageous for Z06? (M7)

i ran an f10 m5 with about 640whp the other day from a 50, walked him in eco. Hope that helps. llol


i'am bone stock.

That is a total 3rd gear pull. The car will pull strongly from the high 40s in third gear all the way to the rev limiter at 123 mph. Some people shift to 2nd at the slower speed but what you gain from a little extra torque from the lower gear you lose when you shift. I do this pull at VIR on almost every lap. Coming off Oak Tree drivers are exiting the turn in the 47 to 52 mph range and just standing on the throttle from the apex of the turn all the way through third. There is a flag station alongside the track a little way out from the turn but after a shift to 3rd is required and I use it as a measure of how well I am doing. I am usually doing the same speed at that point if I use 2nd or just stay in 3rd. If you are running at about 115 when passing the station it is an indication you handled the corner correctly.

The LT4 has a hell of a lot of torque down low so at 3K rpm you don't really need to worry. It isn't like a high rpm peaky engine that has to be revved up to get power. The LT4 hits its peak torque of 650 lb-ft at 3600 rpm and at 3K you are already over 600 lb-ft.

Put the car in Track/Race Mode and you will have PTM to help control tire slip if you over power your tires. Yes, it is at heart traction control but it is a traction control that really works the way the driver should be driving the car if they didn't have traction control. You just plant your foot on the floor and as the tires regain grip it feeds more power to the tires. No bog just acceleration. Sure it pulls power but it is power you can't use anyways since the tires would spin too fast. PTM metes out what is required to couple max power to the ground. Again it does what a good driver should do but there are some that don't know how to use less throttle when the tires are burning up. That may work in a tractor pull or on a dirt car riding the cushion but not on pavement.

what Bill said.. I prefer the track mode just for the firmness and stability.

okaythen

That's great, always good to gain more knowledge.

On highway I have noticed the TC never came on when I do 75 to 120mph, but is it still interfering? Would turning it off be even quicker, I think in some other situations it kicks in but the light doesn't come on.

I actually have yet to put it in track mode after I read that, it can damage the suspension and rims if you hit a pothole going fast enough. You guys put it in track mode on highway? I guess if I am familiar with the particular roads/highway then it should be ok?

spearfish25

The Cosworth data proves Bill's point. If I use 2nd gear out of turn 5 at Sebring and watch my speed curve down the ensuing straight, the shape of the curve is identical to the 3rd gear speed curve (same acceleration). However the extra gear changes shifts my 2nd gear speed curve lower and hurts me in top end by the end of the straight. I'll post a screen shot of the curve when I'm back home.

For turbocharged cars they say on highway don't lug the car, like don't floor it in 6th or 5th gear or it can damage the engine. You want rpm to be above 3k to 3.5k before you go at it.

50mph at 3rd what rpm is that, 2500?

I guess it doesn't apply to our car?

madrob2020

Correct since ours are SUPERCHARGED. Turbo works differently ramping up.

GhostBluZ06

Coming from a turbocharged car I know exactly what you mean.
Good question, Id like to know that as well, but im assuming any shock to the motor/trans at low rpm probably isnt good for the car.

madrob2020

Superchargers deliver boost at lower rpm than turbos thus lower rpm pedal to the metal doesn't cause a problem. Turbos run off exhaust gas/supercharger is directly connected to engine with a belt using crankshaft for power.
