i dont know where it was coming from but it was a squeeking sound.
PS. you might ask others about their mods. I have minimal mods compared to most of the guys here.
1)Volant came with the truck when I bought it.
2)Quad4 TB is a creation of ZQ8 Dawg's.
3)Spacer doesnt help any but has a cool little whistling sound.
4)Zexel was $100 from
www.slponline.com (lie about your vehicle year or they'll say it wont fit. they lie just ask anyone here)
5)ASP pulleys helped to free up a little HP. rpm's rise and drop quicker now.
6)Efan came out of a Taurus SHO with minor modifications (a little cutting did wonders). i also have a 180º thermostat and an adjustable thermostat controller installed to keep it cool.
7)Flowtech Afterburner muffler isnt made any more. I had it on my last car for a couple of weeks til i could afford headers and dual exhaust then it sat on my porch uncovered for 4 years til i put it on the truck. sounds as good as the day i bought it except its on a 4cyl now instead of the V8 i had.
