I’m new to the forum, i have a 2012 zl1 and looking at different pulley sizes. Currently i’m running a 2.35 upper pulley and stock lower pulley. what do y’all recommend for the lower pulley? i’m trying to get as much power out of the supercharger as i can. or is there another upgrade somone recommends?
here is what i have done to the car:
4” roto fab intake
tsp 1 7/8 long tube headers
corsa catback cat/resonator delete
tsp stage 3 cam
tsp pushrods and valve springs
KB boost a pump
ID 1050x injectors
lingenfelter 160 degree thermostat
DSX flex fuel kit, e85 sensor
Reinforced supercharger brick
Lingenfelter High Capacity Intercooler Heat Exchanger
supercharger ice tank

I'd go with an 8.66 lower, or do 9.17 but also step up to 2.45 or 2.55 if you do a 9.17. You could also step up to a ported blower next or ported heads.
