Blower motors are so much fun, huh On your deal I would work hard on getting the primary side of the carb to be great at light part throttle driving with low boost and use the secondary tuning for high boost with better fuel and reduced timing for all out WOT driving with more boost Do you have a boost timing retard feature on your ignition? If not why not
