Excellent advice once again
Hammer.
I'll add to the conversation too - SVO blower owner.
Great kit and unit comes with everything you need to get better from the 4.6 but understand as
Hammer pointed out - rwhp numbers will remain in the 290s to 310s. That's it! Aside from that, it big rwhp numbers aren't what you want but great torque and a complete kit with little to no muss. The SVO/FRPP kit is the way to go.
Price list:
4.6L supercharger kit M-9066-E46.
FRPP blower and 98 5-speed control kit.......$3100
NGK TR-6 plugs.......$15
FRPP 9mm wires (if you still have stock wires).......$75
Royal Purple "Purple Ice" coolant additive......$9
9-10 pound pulley (if wanted).....$60
Gates 111.5" belt (needed for 9 pound pulley)......$40
180* thermostat.......$6
Installation of all above........$350
Prices are for my set-up (98GT manual) and the larger pulley which I highly recommend.
