got a 2009 m8 motor in my snopro chassis, took it out to the mountains for the first time and ran into some problems with clutching. serious low end bog, its only pulling 7200rpm. what weight is everyone using?

2009 m8 motor dropped into a 2010 snopro chassis, it has a chaincase, so a torsion secondary. 162" 2.25 powerclaw.

By Underwood I meant under hood lol iPad auto correct. How much boost do you run on your sled. Seen your video in elk ford conditions it pulls pretty hard. Mine was suppose to be 8 pounds with the spring and shim in my controller but only showed 4 on the gauge.

What style of weights are you running...stock AC or some adjustable turbo weight?? I can look tonight and see what I have in my 09.

Have a boondocker oiless and motor done by Brent and running 80g weights and red green primary spring and shockwave set at 48 degees runs great here and a TKI belt drive with 2.52 gearing very responsive here and set at 8lbs but never see any more than 6 on short bursts and 8100 to 8450 rpm.

The original Boondocker setup used 80g AC weights. Using the Hubs Performance kit with his adjustable weights I am at 85g. This is on a pump gas 09 M8 at max 8psi boost.
