Ah come on! Where are the M6's at then?

I'm going to COMPLETELY guess and say in the high 1.9 to low 2.0 range. My experience has shown a .5 different in ET between manual transmission with good driver and automatic transmission with OK driver in cars with same power and setup, and that was with the older 5 speed auto tech. These new 8 and 10 speed trans cars are a whole different ball game with gears to keep the cars in the torque band and lightening fast shifts a human just can't match.

This admission of defeat is coming from a LONG time manual trans fan, so I don't say this lightly

[S.T.A.R.]

Agreed on the new transmission, however does this current launch issue (falls flat on its face, or spins) play a large part in the difference Speedy.
I'm not interested in a A10 at this point.

Cal's got the record at a 1.991 lol. They're definitely a lot harder to get moving, that's been discussed a million times on here.

But if you compare similar 60' between the two.....the m6 is anywhere from .1 quicker to .2 slower with a mph anywhere from +1 to -7. Now that's only comparing the only two m6 to make passes, but I'll bet we'll see some sub 11.6 passes when cooler weather comes. Also look at the fast list, it's obvious that the autos are consistently faster but you just need to make one pass to make the list We have a track event in December and I'm hoping we have some cool weather that day, I'm keeping my car stock and aiming to beat 11.6 lol

Very good guess....unfortunately. :(

That said, if we end up getting a software fix of some kind to get this thing's fat @$$ off the starting line it should end up with some very impressive times.

By he time my car arrives in early November, Numidia Raceway will be closed for the season. I'll give it a shot come spring though.

I'd say the difference between the two would be very similar to what you see with the ss cars.....with some good air you'll see some 10.9 passes out of the bone stock autos and I'd be willing to bet you'll see some 11.3, POSSIBLY some 11.2 passes out the m6 cars, IF GM's software fix aids in launching these cars. If not, I'd say 11.4, maybe 11.3 under great conditions.

Also, taking a look at the c7z fast list, when you compare 100% stock times, the autos are about .5 quicker through the 1/4 but once you add tires only, the stock cars are equaling the auto times, same when they get hp adding mods

Well, I was dead close on my guess LOL. I have lots of experience in a M6 car at the strip, just is what it is.

I bolded a section there. The problem trying to compare M6 times, is not all drivers are created equal. Those that know how to pedal the launch AND speed shift the car properly will obviously run the best. That will create a massive gap between those that get a decent launch, but don't speed shift.

For sake of definition, speed shift would be keeping the throttle buried to the floor all the way down the track and just stabbing the clutch and snatching the next gear as fast as possible. Took me a LONG time to get comfortable with that as it definitely didn't feel natural at first. Friends of mine tried all kinds of electronic gizmos to aid in this effort in their cars, but I never saw them do much better so I just learned the hard way without any electronic help. I think the M6 ZL1 probably has a WOT shift feature built in though?



That's what it looks like and it's a lot going on. You have to not only balance on the clutch as the tree drops, and NOT roll forward in the process, you have to finesse the launch to use as much power as the track will hold without spinning the tires, wheel hopping, or bogging. Takes several warm up runs to find that sweet spot and with limited time at the track it's tricky.

I had a line lock button on the shifter ball and did my burnouts in 2nd gear. I found about 50mph to be the best speed to get the tires hot quickly, but those were race tires so YMMV on streets. Release the brake and roll forward with the tires still spinning and let them grab the track on their own as you roll forward. You'll also notice I'm checking my mirrors which were each aimed at the rear tires so I could insure both were smoking, AND I pump the brakes to insure the LSD was fully engaged. Doing a one wheel peel can burn up the LSD clutches real quick.

Then just launch as best you can and force your right foot to stay planted. I learned by starting with just a 3-4 shift as it's the easiest. Once I was comfortable there, I started doing 1-2 and 3-4, and when I had that down I went for it and added 2-3 which is obviously the most difficult. I almost never missed a shift with that method, and I mean 1 or 2 times EVER in 100s of passes. The key is shifting that 2-3 like you're 100% confident it's gonna make it. Any tentativeness and it likely won't go. Be sure to open palm that 2-3 shift, had a buddy slip off the ball in the excitement and broke his thumb when it hit the dash. Tucking your elbow in to your ribs may also help with lining up that shift.

Learning to speed shift the car lowered my ET by a bit over 3/10ths and picked up 2MPH if memory serves. It makes a huge difference.

Yeah, it's got no-lift-shift so it should be possible even if you aren't particularly fast at shifting.

[KyleL]

I agree 100%....sometimes it's hard even for good drivers to nail consistent times bc there is so much going on. The zl1 has a few features that help though like the ones you mentioned such as no lift shift and launch control. they can just keep the clutch and the throttle pinned until its go time. They can also just keep their right foot pinned and not worry about bouncing off the limiter either. But it helps these cars out so much since you never lose boost between shifts. Even from a rolling start the difference is car lengths between a zl1 driver who uses its nls function as opposed to one who doesnt. I've also noticed that it's much easier to go between gears in this tr6060 as opposed to the one I had in my 09 vette

[S.T.A.R.]

You're right Speedy, that is so not natural looking. I'll need practice for sure.

The guys above confirmed the new ZL1 has some features to assist you. You'll just have to get used to it LOL. Once you do, it'll be second nature and you'll find it hard NOT to speed shift the car

[S.T.A.R.]

This no lift shift feature, is it always activated?
