Anyone who wants to back out of your spot in the GB pls PM me. Thanks.

GeorgeA · 08-08-2021, 10:02 PM

Same here - I was part of the group buy in late 2020 but not sure what happened to that since I didn't follow up with it. If anyone backs out, let me know.

Isn’t that the same GB that its still ongoing ? They announced that they might ship next Month to whoever was on the list and followed thru with the sale.

swhat · 08-09-2021, 02:43 PM

exciting! only waited a year for this

akkando · 09-12-2021, 12:08 PM

Any news when the group buy is shipping?

pjk380 · 09-13-2021, 11:44 AM

I sent MFactory a PM last week asking for an update. Their response,

"we have just finished assembling/balancing a few intial sets and have shipped them out to customers to verify the fitment/nvh.

Once those have been approved (shouldn't take too long, hopefully), we will finish assembling/balancing the rest of the units and have them shipped out. I'll keep you updated"

If anyone wants to bless me with their spot I'll take it.

I'll throw in a clunky driveshaft to sweeten the deal if we have any takers.

MFactory · 09-15-2021, 10:18 PM

Will have an update with images of the production shaft shortly (from one of the testers)

Small Yellow · 09-28-2021, 01:20 AM

In for GB if still available

peter de la mare · 09-30-2021, 12:53 PM

I’m #1 on the list, looking forward very much to getting my hands on it at long last.

rhyary · 09-30-2021, 01:15 PM

I am, eagerly, waiting for my spare.
So far Gen-1 is finishing yet another track season with no issues I can see.

MaximusB · 09-30-2021, 01:43 PM

sub.

Idfkman · 09-30-2021, 02:49 PM

Do we have enough demand to start up another group buy?

Have you reached out to Michael to see if he has any spares? My friend managed to get one unit in this production run, but obviously not at the GB price.

blowbackpolicy · 10-06-2021, 10:31 AM

Any update on when these will ship?

swhat · 10-06-2021, 07:43 PM

i am guessing they are still testing for nvh.

Redd · 10-06-2021, 07:47 PM

There's more updates in the official GB thread.

cmichaelo · 01-15-2022, 11:15 AM

This dyno testing by Motortrend's friends at Tune Time Performance of a before-and-after QA1 CFDS install in a Dodge showed this result:

"The steel shaft showed us 367 lb-ft and 413 hp. Swapping to the carbon fiber shaft showed us 373 lb-ft and 424 hp."

So in our cars maybe that may equate to around 4-5 lb-ft and 10hp at the wheels.

I definitely felt better acceleration after my CF DS but I did a dyno and it didn't show up in the numbers.

I personally think those numbers are a bit high based on the following reasoning:

Assume the total weight of the rotating driveline mass (gearbox, DS, diff, axles, rotors, rims, tires) is ~250 lbs. So if we reduce the DS by 10 lbs, that's a 4% reduction in rotating mass. Since we loose around 20% of 414HP in driveline losses, or 83HP, then the WHP gain should be around 4% of 83 HP or 3.3 HP. That could be hard to see on a dyno.
