What other supporting mods are needed or suggested?
First and foremost the car has to be in good running shape. You can’t expect the blower to make good power and your worn out trans try to put all that new power to the ground. A good drive train is imperative in putting the power to the ground. Invest in a good rebuild or built trans if in the budget. A good torque converter with a higher stall speed will also help get the car in the power band quicker. Any supercharged car in my opinion needs gauges. Bare minimum is Boost/vac, Fuel Pressure and Oil pressure. After that I also highly suggest a wideband air/fuel gauge. All this instrumentation is expensive but it can help save your engine if something goes south. During my fuel pump problems, if I didn’t have a fuel pressure gauge and watch it religiously, I wouldn’t have noticed the oscillating needle and could have damaged the engine. A built motor is definitely suggested for getting big power and handling a ton of boost. Ford Racing makes short blocks as well as complete long blocks
