I have the 60-1 impeller in my CT, if that counts? I think the main difference is less lag for me, spooled fast and pulled pretty high into the revs. It spooled a bit slower than the Stock CT but you noticed when it spooled a lot more. You could top out 4th and still be pulling really hard. I'm sure a real t60-1 pulls harder and also has sick top end pull if you are ever brave enough to use it. My difference was 2 seconds at the 1/4 compared to bone stock. I also had a good tune.
Driftmotion? I thought I heard they went bankrupt. JK. I don't know anyone who runs a DM Turbo kit. I imagine it's good if the price is right. Are they bushings or bearings?
