Whipple Supercharger Pulley Swap

[NikkaBun]

Old topic guys my apologies but new to the forums. I have a 2017 S550 Mustang GT with a 2.9L Whipple currently running a 3.75 pulley. My supporting mods are 55lb injectors, Whipple intake, Factory TB, AWE Cat-back and a stage 1. I am up north where 93 Octane is readily available. My question is can i safely run a 3.625 pulley without blowing up my engine?

Probably

Wouldn't that be a question best posed to your tuner?

I’m just using the whipple tune. I wasn’t sure if anyone else has done it successfully

Probably need to add a BAP at a minimum
