I will never know because I'm swapping out mine for a ice attack tomorrow. Its not that I don't like the track but I need something for icy trails and I don't want to stud such a deep track. What are you seeing for top end? It weighs 4 lbs more than the ice attack and it is about a 1/2 inch deeper lug so I'm thinking it won't be the best top end track but I'm sure it will rip through the deeper stuff.

I hit 173 km/h (107.49 mph) today on a groomed trail, sled is 100% stock still. I think I could have squeaked another 5 km/h out if it but I had to let off. I'm happy with that. I also played in the powder and with the backcountry she stood right up. Must say I'm pleased. Now to install my Ulmer clutch kit to see if it makes any gains up top.

So I was lucky enough to be the first one on the freshly groomed rail bed this morning. It was -20c or so. I've installed my ulmer clutch kit and on the crisp hard packed snow I had her up to 177kph (109mph). It would consistently run at 175kph for as long as I'd hold it. Clutches look great. I could keep my hands on them, weren't hot at all. So is this all I'll get with the 1.75? Secondary is at 60, thinking of trying 70. What do you think? Still stock, not flashed yet...

I think for a 1.75" track your doing pretty well. Much more than that and I think your gonna start stressing that track quite a bit
