[QUOTE="SheepDog, post: 15983824, member: 190599"] Just thought I would follow up on this. I went down 1 size pulley to a 3.4". at 7200 RPM, I am seeing 8.3 PSI. At sea level this would be somewhere around 13 PSI. With the P-1x, OEM Harmonic balancer, and this 3.4" pulley the blower is spinning at 61,319 RPM at 7500 RPM which is basically the max recommended speed for the blower. I think that if anyone else is considering a Centri and lives at high altitude, I would have to recommend going with a larger head unit like the D-1x or Paxton2200. You won't have to spin it so hard to achieve the kind of boost you want. [/QUOTE]
