DFW, TX Buick Guy
Hi and many thanks for all of the great information! I have especially appreciated the detailed tech write ups with example images.
I had moth balled my 1992 Buick Park Ave Ultra after hearing a horrible rattle coming from the engine bay and finding that it was coming from the supercharger. I loved the car too much to put it out to pasture, but couldn't swing the four hundred fifty bucks for a used low mileage supercharger. Thanks to a posting on ebay noting the ZZP coupler as a possible solution and the tech write ups from this site, my big black Buick is back on the road! (Though the nose assy is still leaking a bit -- groan). I guess I'll try and apply the parts numbers that your members provided to get a new set of bearings and a seal pressed into the nose assy as soon as I can find a willing machine shop in the DFW, TX area. I had given up hope on ever modifying my Series 1 after being told by numerous Series II Pontiac GTP owners about problems with the 4T65E which was supposed to be stronger than my 4T60E and being told that the Series I supercharger was spinning at its optimum speed and would only create parasitic heat losses if I tried to go to a smaller pulley.
I was introduced to a Fiero enthusiast who had experience modifying the */c 3800 via a friend who'* a Buick Grand Nat'l owner. He reassured me that the 4T60E is not as fragile as I had suspected as long as I keep it cool and convinced me to try a 94/95 supercharger and throttle body assy. Your site has provided quite a few examples of Series 1 enhancements that I'd like to try (finances allowing). I've since saved a frew nickels and bought a 94/95 supercharger and throttle body off of the web, but haven't installed it as I'm hoping to get a 2.5 inch pulley pressed onto it. (Are there any Pontiac Bonneville Club members in the DFW, TX area with a pulley tool that will take a few bucks in trade for their expertise?) I don't plan on installing the */c and throttle body until I've got the suggested colder spark plugs, better wires, cold air intake, and better flowing muffler in place. I still need to find an example of the parts recipe for building my own CAI, a recommendation for stiffer struts (mine are terribly fatigued), and the part numbers for a better sway bar. I'm hoping that the 92 - 99 Pontiac J-Body parts swap without major issues between the 92-99 Pontiac and 92-96 Buick variations.
