The 2020 370z needs a DCT

Spooler · 01-27-2021, 09:36 AM

I like rowing my gears still. I will hold onto my H pattern for as long as I can but my input shaft is going to hate me. 3rd gear too. Glad to see this is up and running so I can have an option
to do it if needed.

I hear ya, but depending on the road coarse not having to row your own can be a couple of seconds or more. Paddle shifting is quite fun on a road course.

i want a sequential, but this is also very cool!

DCT is actually faster than a sequential. There is a reason Porsche, BMW, Audi and others don't use sequential in their racecars.

Did he delete the vid, or am I just bad at Instagram?

yeah I know, I just like it more i guess.

Last year I was buying a Honda Africa Twin (before covid happened)

And I waffled back and forth whether to get the DCT or manual with quickshifter. I know the DCT shifts much faster than any human could. But I ended up deciding on the manual because I thought it would be more fun.

One test drive or ride along and you will be back here to delete this post

IMHO it depends a lot on the power level. Over 500-600whp, shifting yourself can be frustrating as it really holds you back from getting the most out of your investment into the power, and your competitiveness. There was not a single time I drove my GTR that I wished I could shift the gears manually. DCT I think is equally fun, just in a slightly different way. Its insanely aggressive and efficient, and the shifts are so damn satisfying, you wish you had 20 more to go through.

Hmmm... wonder if this will be legal for GTA street class...

Any idea on weight difference between the 6mt and the DCT?

phunk · 01-27-2021, 06:25 PM

Its tricky to get a fair weight comparison since we have to compare a bit more than the trans itself. Need to take into account the clutch and flywheel kit on the 6MT versus the flywheel and adapter for the DCT, different trans mounts and driveshafts. I can get numbers from just the trans pretty easy though as I have them sitting side by side on the shop floor and a scale isnt too far away. But my back isnt in the mood to lift them up right now

I don't think so for our cars. You will have to jump limited class or higher. You can't run street class anyway being boosted I didn't think.

I ran street class last year. Power adders aren't restricted (nothing written in the rules against them) Tons of S2000's with superchargers too.

The only thing the rules say for transmissions is "Sequentially shifted gearboxes are not permitted unless OEM. Gear sets are open"

Guess it depends on the interpretation of "Sequential" but my thought is no based on the fact that the DCT can skip gears if you tell it to.

Completely understand haha would be nice to know sometime down the line. I'm sure the time savings will outweigh the weight tax though.

Also if there is any weight gain it is in one of the best spots low and mid carish.
