the new guys 500rwhp write-up

Nissan370

with the v-2 on my mustang the kit came with 3.60 pulley 6rib for 8psi

i was getting a lot of slippage as i went from 3.6-3.33 then 2.95 so i opted. for an 8-rib pulley kit and the 2.87 (2.87=14psi @ 6100 rpms and 16.5-17 psi @ 7200 rpms)

with that 2.87 pulley i was at 8psi @ 4400 rpms


mustang mag did a project were some guy put a waste gate on his vortech

he got the ysi blower dropped the pulley size down so that the blower would make max boost up top like 20 or 22 psi or so added the waste gate to bleed the boost off at like 15psi or so

the dyno chart looked like a turbos dyno chart he was hitting hit 15 or so psi mark very early in the rpms

here it is Vortech Centrifugal Supercharger Wastegate Install - Muscle Mustangs & Fast Fords Magazine
