ive got a 90'SC auto! ive already did the exhaust with flomaster cat back system now considering a 10% overdrive pulley ! im kinda confused .. i understand that the smaller overdrive pulley is designed to spin the supercharger faster for a boost increase ; ihave 3 questions in this matter?
1.) how much more boost will i see with the 5% pulley or the 10%pulley in compared to the stock pulley.
2) i having it hard understanding this concept.. ifthe overdrive pulley for the jack shaft is designed to speed up the supercharger for more boost , their are available underdrive pulleys for the accessories that whereas the crankshaft is allowed to spin the accessories slower to retained robbed horsepower. so then if that is tru in slowing down the accessories with the underdrive pulleys the super charger would turn slower as well ,but adding the 5 or 10% pulley seems to me it would only bring the jackshaft back to the normal ratio.. please someone helpo me wit this cause im fairly lost!
3) how much of a horsepower gain can be expected using the 5% or 10% overdrive pulleys.
