Topgunz - air to air upgrade

I didn't, I only changed the supercharger pulley, I got that from Vortech.

What size did you use and what was the boost?

I broke the first supercharger with a 2.75 then changed to a 3.0 for the second one, it was around 10psi but not 100 percent positive. I have long tube headers on my car so it's going to be less than others will see with cats. I don't know that over spinning the supercharger caused the first one to go but I wasn't chancing it. At the track my car sees red line hundreds of times in a weekend so it takes a lot more beating than most street cars.
