You can deny reality all you want. We'll be over here. Driving our faster automatics. Auto Boys, roll out!

I’m not sure what you are trying to prove. I agree that the 10r80 is faster stock. All you are debating is personal opinion on what quite a bit is. Non of this makes your 10r80 faster than my 6r80. Once you modify the car one is not better than the other.

According to who?
This was over 3 years ago, and they haven’t slowed down

Check the drag strip section. Plenty of stock guys in there who have been 11s.

Not saying it can’t be done under perfect conditions once. But consistently in a 100% stock 2018 is not the standard

What rear end? The 10R80 equipped cars have stock 3.15's. What trim level? Drive modes make a big difference in the feel. Stock for stock? Same tires? Same fuel? There's a lot of factors to account for here.

3.15 rear end. GT Premium with 401a group, was in sport mode, have 19 wheels had 18s on my 16 and 93 octane in both cars.

16 was a manual.

I would not say that a gen3 I quite a bit faster. A 2015 1/4 at 12.7 and a 2019 at 12.5 and 12.9 depending on trim so no exactly quite a bit

In ~1100 DA, full weight with 1/2 tank fuel, and IATs at time of run at 140+ due to not having time to cool the car down after my drive to the track, I ran 12.2 at almost 118 with a 2.0 60' in showroom stock form (non-PP1 car). That was my first pass ever in this car. Taking that into account and your advertised 12.7 for a 2015, 1/2 second will look like a beat down on a drag strip. With full weight, 230 DA, a proper cool down, and only mod being wheels/tires, I went 11.55 and 11.56 in back to back runs. Show me a 6R80 DR only car with full weight and stock tune that ran close to that.

There are plenty of examples of people running 11.9s-12.1s in stock 10R80 cars The term "quite a bit" is totally subjective so I'll avoid that term but a guy in a stock 2016 GT who was at the track the night I ran the 12.2 was running 12.8s for a comparison.

I gotta disagree. My 6r80 15 GT ran high 9 on e85. The same mods on a 18 up are netting mid to low 9s. The 10r80 simply keeps the car in the meat of its power-band better than the 6r80.

ha I even managed to relate this to the supercharged section bitches. Now off to the general section with this thread!

There's the answer. A manual "feels" faster. The linearity of the Coyote, and low shift times make the speed come on very effortlessly. I guarantee the car is faster. Try Drag Mode out if you want some more violence.

Yup just sport mode (S shift) can't touch with the shifter in D in either track or drag mode. OP give those a shot and it's a very different story even with the 3.15.

My car seems to lag a little behind some of the 3.33 pulley Vortech/Paxton 10r80s locally and a lot of times they seem to trap well since the 10r80 is doing a good job keeping it in the powerband and yet the good ol’ 6r80 slushbox is ahead in ET. So the whole “see what happens when you go boost” is stupid.

That’s most likely your aftermarket converter putting in work. The 10speeds are about half a second faster than the 6r Stock. Faster stock will equal faster boosted when all the other aftermarket set ups and driver skill is taken out of the equation.

Also i apologize for posting in the wrong section. I meant to post in the 5.0 engine section not forced induction.

I don’t follow it too much. But you or some of the NA guys here know what the fastest NA 10r80 and 6r80 are? I’m guessing the 10r80 will be .5 seconds quicker than the best 6r80 time.

my converter is hardly a converter at 2600 stall. Marginally better than stock. But not bad if it offset the motor advantages, the trans advantages and the higher overall output of those other gen 3 cars.

16 was a manual.

What gears were in your 16? That can make a difference in how it feels. Gen 2 and Gen 3 are pretty much the same with manuals, but the Gen 3 auto should feel faster with the .5 second difference.

We are still only debating what quite a bit is

Once you start modifying the car you can gear it for the 1/4 or 1/8 or whatever you want. Once you start making bigger power you don’t always want so many gears. A lot of 1/4 built cars only have 4 gears some less

Yea I’m not talking about race cars with th400 trannys. I’m talking about your garden variety boosted street car. Like the majority of folks in this section have. But I think the only guy with a street driver car in the 7s on this forum & the fastest guy on our fast list is still running the 10 speed. Dudes that are using the old Chevy transmissions are using those more for durability and consistency then flat out being faster.
