Sounds like a great idea....I’ll reach out to him before we send the charger out to 928. Thanks again Pat. If the waste gate doesn’t happen what pulleys would I need to change out to get up to 13psi? I’m currently at about 8 to 8.3psi with the 9lb SC pulley that Stillen sent me which is on the Jack-Serp side. This low boost has tk die wit my location, weather and sea level factors

I used the 9lb and a 2.85 supercharger pulley to get to 13 psi (12.86 to be exact). You'll have to go to a 3.00 idler on the supercharger side if you go with the 2.85.

Awesome... Will these pulley changes require the spacers mentioned by Cupcakez? I know it was mentioned earlier On the thread I believe by by imazman that it was a pretty tight fit on the idler pulley (SC Side).

As long as you do not change the jackshaft pulley on the supercharger side, you won't need the spacers. You may need the RPM belt instead if your goal is 13psi and you put the filter on, depending on the belt tension and impeller.

As mentioned by"Z"en, you won't need spacers unless you change the jackshaft pulley, sc side. Also, the idler wasn't a tight fit at all. No issues using the 3" idler.
