Hellcat low boost

[Miketango]

hi Guys,

i have a Ram 1500 that i fitted a Hellcat motor to, the first 9000 miles the Ram pulled like a beast.
but now it feels like the power has disappeared.

i did a log and see that i am only getting round 5-6 PSI boost, what can the problem be?

the belt is not slipping, everything on the engine is still stock.

How much boost does it normally produce? I didn't see any knock from bad fuel. Did you happen to pin the balancer to prevent it from spinning on the crank? Im sure its something else but just in case.

i will check that, on the logs i run round the 18psi on 3000 rpm, then it starts to fall off

stock engines run around 11/12 psi depending on elevation

it will never hit 18 psi unless you have the smallest supercharger pulley and overdrive pulley
