[QUOTE="Gruca, post: 16244401, member: 153163"] How many pounds of boost do you see with the stock air intake? I thought I had belt slip so I changed from a 3.33 to a 3.48 pulley. The tensioner is pretty much topped out now with the 3.48 and the idler in the second from the left hole. I made a homemade boost leak tester and found that two of my injector o-rings were bad. Fixed those and the car held 15 psi with compressed air. Now at 7k rpms, I’m seeing 10psi of boost through the stock air intake. Running Kooks Super Street 1 7/8” shorty headers, lethal x-pipe, lethal OTAs. Wondering what you all are seeing with the same pulley. [/QUOTE]
