Ok well I did want to post some of the first ideas and mods I have done to my 90 auto SC. I installed a 255lph holley intank pump not the funest pump to do hahaha. I removed the cats and resignator and added 2 1/4 in dual pipe and connected it too the back pipe. I plan on adding a 3 to 3 1/2 inch pipe going back into dual 2 1/4 pipes to free flowing mufflers. Maybe headers if I can afford them. But I added a 9 in open K&N cone filter and no silencer with a cold air pipe coming up to it. I also came across something pretty neat I was looking at a 2002 pontiac grand prix that my buddy has wreaked in his garage and he was junking it because the engine trans and frame is bad so i asked if I could have the supercharger. He said sure and I took it home and took it apart only to find that it has the epoxy coated rotors. I took off my supercharger and to my amazement my old 90 bare rotors and their coated new rotors are the same a direct drop in!!!! I assembled the whole thing added new supercharger fluid and bolted it on to the car. It feels AWESOME!!!!!, My boost came up 2 PSI to a full 9-10 at full throttle I don't know why its not over 12 but read my other post and then maybe that will clear up why its reading low. But before i could only get 8 solid PSI. So where should I head next my goal is to have about 350-400 crank HP. Thanks for all the insight and hope this helps some others with their goals. Could be a cheaper alternative than the S blower. I also ported out the rear of the casing while I had it off too and polished the housing for a good seal and believe me it is pumping ALOT more efficently!
