7 speed DCT vs 10r80 for Drag racing? Road racing?

[Andy13186]

Am I right in thinking the 10r80 will be better for drag racing, especially once torque converters come out? Is there a good way to launch a DCT on a drag strip? 10r80 can get a Tbrake tune too with no mods.

Im sure the DCT will be better on road courses but, on the drag strip I just dont see it being better than 10r80 as far as I know

DBK just posted up at SVTP. Transmission is indeed a Tremec DCT.

Someone leaked the brochure online. It's a Tremec 7-speed DCT, which is what it always was, since inception.

I'm no expert on the DCT but I've been told that on some variants as long as you're on the brake the clutches are not engaged, they engage on release of the brake … anyone confirm this?

DCT doesn't require a torque converter, but I suppose it is possible to put a torque converter in there. Without a torque converter, I don't think you would want a partially engaged clutch preloading the drivetrain. You'd wear out clutches left and right. So from that standpoint an automatic would be preferred for 1/4 mile work.

McLarens are the king of the drag strip right now with DCT's. DCT launch controls are pretty savage but they seem to work. They all rev the engine up to a specified RPM by the computer and then you pull a paddle or release the brake or some combo of actions and the computers take care of everything, releasing the brakes, engaging the clutch and managing traction control through first or second or both gears.

Im gonna say the 7 speed tremec would beat a 10r80 in a quarter mile.

DCT is a big boy upgrade, and the right thing for Ford to do. Who wants to buy a GT500 for drag strip work? Maybe someone, but I wouldn’t. For that route exclusively, I’d just spend the money on a fully built Coyote Mustang. Sky is the limit on that platform.

The DCT is going to surprise many folks and when the old school manual trans are getting whooped on, I wouldn’t be surprised if some of those convert over to a new GT500 or try to do a DCT swap (it’s coming, someone is always the pioneer of a swap)...

Same thing happened when the 10R80 made its way into the 2018/19 Mustang - quite a few dedicated MT82 owners eventually swapped into a 2018/19 after experiencing a drive with the 10R80.

I’d also suspect the DCT is probably going to make it into some other Mustangs as the popularity grows.

The Cobra Jet is where it’s at for full drag ready Mustang IF someone wants an out of the box drag purpose built Mustang.

Yes it makes sense that a super light, mid engine vehicle with lots of power will launch quickly. What if you put a torque converter automatic with a trans brake in it?

I think if you were going to build a drag focused car you'd be right, you'd want the TC auto. But for an all around production car I think the DCT will be an advantage. There's more they can do with programming and they can mesh the LC system with the traction control and the drag setting. Also the dct should be able to slip the clutch better finding low speed traction.They'll be able to launch at a higher rpm more easily, most tc autos you can only launch around 1900-2200 rpms. The DCT will also shift faster with no torque interruption. I'm hopeful the DCT will provide better results both on track and at the strip.

Not at all convinced, but it might be too close to call without actually running them side by side. The 10R80 has more closely spaced gears (slightly higher average torque available at least at the crank), but that means more shifts. ECU/TCM programming would be key for both.

Here was some of the hype over the 10 speed transmission when it first came out :



"With world-class shift times on par with the world’s best dual-clutch transmissions and the refinement that comes only from a true automatic, the 10-speed delivers incomparable performance on and off the track,”

• "Quicker shifts than a dual-clutch transmission – Testing has shown faster upshift times than the Porsche PDK dual-clutch transmission. In fact, the 1-2 upshift is 36-percent quicker than the PDK, while the 2-3 and 3-4 upshifts are 27-percent and 26-percent quicker, respectively."

Mclaren, porsche, ferrari all use some type of DCT. 10-speed is for the lower level mustang. DCT is for the Ford GT and GT500.

McLaren, Porsche, and Ferrari all sell cars using an element of snob appeal. Ford . . . not so much.
