Allright, valentines day is coming up, and my dad asked me to find out how much a Radix supercharger costs and about how much horsepower increase he can expect from it on a completly stock 2003 H2. Its my moms hummer, but she had hinted to my dad that for V-day she wants either 24 inch spinners or a supercharger for the H2, Spinners are more than likely out of the question considering my mom is white, and they cost around 10 thousand bucks with tires. Any feedback would be wonderful.

About $5000 plus installation,figure just under $6000 and you'll see about 140hp increase.The 140hp increase at peak doesn't tell the full story because it makes more power at any engine rpm you will see an increase of about 120 average hp,big difference.It feels like you installed a 500 cid engine.
