Castle 2200 on 4s or 6s

Hoov,couple questions. How long did you run each setup? The temp ranges given,were they taken at different times,or different spots on the components? IOW is that the temps they leveled out at,which both seem fine.With the 4s did you have those temps at lvc?That seems a little high,my SPC's usually stay around 5 degrees warmer then the ambient,but I rarely run them to lvc.1 more thing,where are you getting your speed estimates?Since My Medusa 2000 runs 44 with 24/68 gearing,on 4s,I'm wondering what the 2 setups would radar at.Are you running LPR tires?
