2009 Phazer MTX
Nice speeds! I’m still waiting for someone to plow a straight road on the lake. With ~6” of windblown snow I managed 89mph today, 88 on my gps. I’m pretty happy with that, my Phazer pulled 74 on the speedo, 68 on the gps about an hour later. The Phazer has gone 85 GPS on a plowed road, hoping to tick the century mark with the Viper.
Here are specs. It is a long spring not short.

Thank! This spring don't have a lot of preload... what is your engagement RPM?

Right around 3000 I believe. It's easily loaded up ramp Into truck or trailer but still hits pretty hard on launch when on it because of the wieght profile. I like it.
Next test should be tues or wed after work. Will leave the current helix on and try the smaller rollers which should allow me to remove some wieght and tune clutch. This weekend the snow was deep and soft nothing groomed or if they were it was quickly covered by new snow. I ran my stock modded can same clutching and lost on average 600 rpm so was always below 8800rpm. GPS says highest speed for weekend was 95mph. more than fast enough to keep up with or lead 2 brand new Cat 9000's and a 18 Doo 850. Conditions slowed us all.

I have no idea. Never had one.
Here we go again. Changed to smaller 14.5 rollers. Thanks DranttelSS!
Looking at the vids I see the reason for the 9211rpm on recall. She spun at over 115mph that run. I am actually right at 9050rpm@107mph. I will try taking some weight out. So smaller rollers were in fact a success. That was only change. Will get there earlier tomorrow. Stupid work always gets in way!

You got to be able to tell a difference on how hard it grabs on bottom!
Oh yes! Never spun that much ever and when it hooked it hooked hard. More screwed up conditions. Now the ice is hard as a rock but hardly no snow other than drifts. Thank god I have good suspension!
Best video I got tonight. Darn glad I had the go pro since tach recall fooled me. Small rollers did exactly as said by Studroes and yammitrip. This will allow me to pull some wieght from the primary. May have to resort to my secret road though unless we get some snow on the river. I don't have enough studs for pure ice.

Youll get that 110 for sure! Skip lunch today!
