I'll let one of the resident drag strip experts chime in (e.g. @AlfaPhilly) but I think 45WHP on a QV is good for maybe a 10th or so.Yeah, Madness say up to 16% gains, and we're seeing 10% here. Who knows if that's natural variability of the engines, the dyno, climate, or what. 444rwhp baseline seems about right, though (from the perspective of drag time calcs and benchmarking QV 12sec times). An extra 45rwhp will shave half-a-second off the 1/4 mi time, though!
