Topgunz - air to air upgrade

milkcow500

Vortech offers a bearing/seal replacements at an additional cost when you do the SI upgrade. Correct, 928 has the high speed bearings.

I believe Z1 is continuing the 9 lb pulley, but I think they are upping the price.

[strike] I must have spoken with someone who didn't know much. I told them about a separate bearing upgrade, how others do it on the forums, etc. They were quite confident and sure Vortech doesn't do ANY bearing upgrades to the supercharger.

Glad I didn't do it yet! Now I know to speak with someone else from their team if they don't know about it. [/strike]

EDIT: I can't read!! Vortech has bearing replacement, 928 has the upgrade.

I've been trying to find out what pulley Z1 is using for the upgrade so I will know if my kit is compatible. I asked them "is the 9psi pulley they have the same as the Stillen or is it different?" there answer was "yes". Now I am 50% confident it is compatible...........

The Z1 price is currently at $155 which is less than the Stillen and more than the Vortech.

Does Stillen still offer the 9psi pulley? I was going to order the one from Z1 but if you're not sure if it'll work with your kit them I'm going to hold off.

It appears Concept Z has the Stillen pulley
