I AM RUNNING A 306 WITH TFS TWISTED WEDGE HEADS, TRACK HEAT INTAKE MANIFOLD, X-303 CAM I AM SHREDDING BELTS LEFT AND RIGHT WITH A 6-RIB SETUP, I AM LOOKING FOR 15-18LBS ON A V-1 SC TRIM I WANT TO GO 10 RIB SETUP AND NEED TO KNOW WHAT PULLIES TO GET RIGHT NOW I AM RUNNING A 6.87"(I THINK whatever came with the kit) CRANK AND A 2.87" SUPERCHARGER PULLIE I GET 6-7 LBS AS IT SITS NOW
WHAT PULLIES DO I NEED TO MAKE THIS BOOST????
I think your going to be hard pressed to get 18#s out of an SC-Trim on that combo. I would recommend an 8"/2.95" combo. I think that might yield you 14-16#s with minimal belt slip, but its going to be maxed out. Maybe 10 rib would hold more, but your just going to be spinning the hell out of that blower.
i appreciate the reply i ordered an 8 rib setup-up with 8" crank and 3.15 Upper hopefully i will get about 15 out of that.
