jamminvr6storm 0 Posted April 26, 2008 When I bought my Vortech i was given a few pulleys as part of the deal, I want to upgrade my 8psi one for a 10psi.... Can anyone tell me if the pulley in the attached pic is 12 or 15psi? Also, whats the size of the 10psi pulley? Quote Share this post Link to post Share on other sites

H8RRA 0 Posted April 29, 2008 see now, i'm running a bigger cooler so maybe dropping some pressure due to its volumes - i stayed safe at 11psi at about 47mm i have 4 pulleys i could do a swap with you if you know the size you want... Quote Share this post Link to post Share on other sites
jamminvr6storm 0 Posted April 29, 2008 I *believe* i need a 2.5" (63.5mm) to achieve 10psi ? Would settle for 60mm.... Got anything near there H8RRA ? You must have a big FMIC then fella ? It looks like the pulley you have atm if 47mm is only 2/3mm bigger then this one ? Quote Share this post Link to post Share on other sites
