Running 17.5 DUO2 (no timing) and geared at 3.5. Motor is temping at 145 so I guess I can try the 3.2 FDR that someone recommended. My question is, how come I can gear the car with the BMC to ~3.5 when others (Tekin, LRP) are way above 4.0 using the same motors? The speeds are about the same.
Also, how come timing 5 feels faster than 6?
