We've broken an O/P shaft, at the time the car was making around 880hp and weighed 3950ish (w/d). We had just put a new set of slicks on. We upgraded both the i/p and o/p shafts while it was apart. We got round the speedo issue going to a Dakota Dig dash with a GPS speedo. ![[Linked Image]](http://i.imgur.com/e12y9WB.jpg) Yikes! Killed the sprag, too!
