Ive been using the cheaper Max Tourqe drums for almost year and finally got confident enough to get a disc clutch. It engages at 3,900. Running it on a Predator Hemi with CL-1 cam and 10.8 springs. I noticed my last race my usual gears 14/60 (with the max tourqe) felt like i had slower acceleration using the Disc clutch like i had a taller gear. Is this normal? Do drum and disk have diffrent gear combos?
