Got the car done and dyno'd Saturday morning. After getting the misfires from shitty old plug wires taken care of. Car made 470 with a ton of belt slip. 7.5 lbs full boost dropping to barely 4 between 4-4500rpm. Have an ecs tensioner already installed so my guess is shitty belt.
Just ordered the gator green belt. Should be here in a couple days. See what happens.
I saw a writeup for adjusting the rear pulleys as well, anyone done this? How hard was it with the maggie still on the car?
My belt was slipping and riding off center on the Power steering pump while at the dyno. I put a Gates on and added the maggie HD tensioner. Had to push the PS pulley back also. Vortech T Trim off the PS pulley setup. Got up over +550whp, but with the slip fixed IDK where i am exactly.
Tuner said i am real close with the tune and with no slips, tune should still be right on when boosting up top.
