I will give you an itemized list of "ballpark" figures of what I spent on mine.
One thing to consider... I am
not the sharpest knife in the drawer... I'm sure a lot of guys can do this a lot more cheaply that I did it; just a caveat.
I could have, I suppose, gotten a ProCarger kit from the Supercgarger Store, and saved a few bucks, I dunno...
I wanted a Vortech (brand) blower, after reading about Powerdynes, Prochargers, Paxtons and Vortechs. I think there's a new company making them since I made that choice, but I can't remember its name.
But, to get to it...
Supercharger, a V-1, S-tri, Vortech, ner in the box, $1,000.00 off ebay.
Carburetor, a 4150-series Hollley 750 dbl. pmpr. (vacuum secondaries won't work) $900.00 (NINE HUNDRED dollars) from the Carb Shop in Ontario, CA.
Half-inch fuel system including a fuel cell and two electric pumps (one, a backup; I don't trust 'em.) Including a lot of A-N fittings and some VERY expensive hose, and a boost-oriented regulator and by-pass system, probably $1,500.00, and that's conservative... more lilely $2,000.00.
Home-brew mounting plate and charge delivery hardware, incluing a blowoff valve, pulleys and a serpentine belt to drive the blower, maybe $350.00, and the guy who sold me the blower
GAVE me the bottom serpentine pulley.
MSD BoostMaster ignition system and coil, $400.00 (estimate; I don't have time to look it up.) But, that's close... Not really a necessity... could do without it.
OIl filter system and delivery hoses for blower: $75.00 (another close estimate, I think). Again, not a necessity, just something I wanted to do.
Not a cheap deal, and there are lots of ways to pick up 100 horsepower without spending all that money. Nitrous is a lot cheaper, so you pays your money and you takes your cherce...
Hope this helps.
