Inspired by Robert Thorne’s “Big Bad Wolf,” the self-professed “fastest Honda S2000,” Alexander Moss and Andy Smedegard wanted to build an even faster S2000. They now have one that rivals that famous vehicle. Meet SuperK, a K-swapped, DCT 2006 Honda S2000.

SuperK won the 2020 King of the Mountains autocross event at UMI Motorsports Park. It took the 2020 Gridlife championship …

Very interesting read. I knew a few things about this car but I greatly enjoyed this deeper look.

are BMW DCTs the new "cheap" sequential? I'm certainty interested in flappy paddle 7 speed with my low power car, would make for a riot on stage! 

 

its not like my 130wtq is going to break something mean for a high power/weight BMW lol

That's been a thing for a while now. N54/n55 DCT transmissions being cheap and all.

knew I had some pics from SuperK's first OneLap, when it was supercharged, and they were pulling the belt off the supercharger pulley for transits... was just looking in the wrong thread.  I forget what Andy was tweaking here, after the Grissom Autocross (iirc)...

edit:
even got an "artsy" shot from Nelson the next day:

Interesting amalgamation of parts .... can't imagine the amount of work to get them all to coexist and play nice.  But, it's not easy being green ....and since the car reminds me of nothing more than Kermit the Frog, seems appropriate.

Anybody have any insight into the "the aluminum flywheel kept trying to exit the car so we pushed them to make a CrMo one" part?

I can't imagine there's anything about a K24 that's... I dunno, allergic to aluminum?

I'm no expert on flywheels, but this is something I'd like to know more about before it becomes a practical matter.

My guess would be the rpms and the forces on it from the dual clutch system

ARA rule blah.whatevs.(blah) sez that transmissions may not be electronically controlled.

Could be.  IIRC the BMW trans generally just uses a coupler, clutch is internal.  If BMW had a dual mass coupler and the Honda does not, that can be a recipe for ugh.

Worth the watch:

Also worth mentioning that Andy is fantastic to deal with. I was in talks with him on swapping the DCT into a project of mine, and after going over the parameters and goals, he actually talked me out of it. Not because he didn't want my money, but because it wasn't the right transmission for my project. That's class. =)
