my altitude is 1066’. I just want to figure out if it’s easy to add more boost or if it requires lots of modifications.What altitude are you at?
Hi everyone, Just wondering how much is the normal amount of boost for a stock 18 hellcat? Mine has 11 psi. Is their anyway to increase the boost without changing any pulleys? Thankswww.hellcat.org
You'd have to change your pulley and retune. Pretty straightforward but you'll need an unlocked PCM, and if you add enough boost you'll have to also upgrade your fuel system.my altitude is 1066’. I just want to figure out if it’s easy to add more boost or if it requires lots of modifications.
My info is the boost is limited/regulated to 11.6 psi.After driving around my 2020 challenger hellcat, I’ve noticed that it Max’s out at about 10PSI. Is this factory electronically limited?
