sale is for a Procharger system for 1985 thru 1991 corvettes. This kit uses the Larger HO D1 head unit, capable of 925hp and 30 psi. As setup on my vette with the 4.00" head pulley installed it delivered 10psi at 5000rpm and 14psi at 6500rpm. Delivering 540rwhp and 494lbs of torque to a relatively stock motor. I had a stealth ram intake, headers and flowmasters. And a programmable ECU. The stock piping was modified by the installing shop for a GReady blow off valve and to eliminate the mass air meter since I was using a speed density ECU, and get around my larger radiator. There welding wasn't show quality by any stretch but it got the job done. The head unit is in good shape, but had some scratches and marks where the steel braided oil line rubbed up against it. Ive included the FMU that came with the kit that we didnt use. Everything works great, it's a wonderful unit, but I've decided to try my hand at a turbo system. Check out the specification of the system at don't have the installation manual but I will do my best to label everything and write a brief description on how to install based on how I uninstalled this kit. I'm also including the power steering pump bracket that must be modified to install the kit. That way you don't have to chop up the one you have. Thanks and happy offerding1985 1986 1987 1988 1989 1990 1991 vette corvette Chevy Chevrolet
