Surprises me that the FM 1 doesn't hold the torque, she is rated for 319ft/lb thats over 450Nm!! That's alot !! When I see that a standard Greddy makes "only" 170ft/lb and at 10psi it should turn around 240ft/lb ... strange

When I asked FM they said they've sold lots of clutches, but don't really have reports either way from miata turbo drivers that track frequently.


The solution will come in the form of a 4 puck. Just haven't gotten to changing it yet. The fm1 starts ok in the morning, but when it gets some heat into it, it slips. I've got a little 1.6, I'm not making Y8s torque here.
