Did a horsepower calculation ( crank) on my 3800SC series III swap and it came out that by adding a 3.4" pulley to the supercharger, a free flow exhaust and a couple of simple mods the engine could produce 339 horsepower. This is with the 11 psi of boost that the boost gauge now shows at WOT. Bottom line the 3.4" pulley adds significant power. On the 3800SC series II engine the power should show about 20 hp less but that's also significant,
