ok so I installed a ottp stage 1 kit last night and took the car out and gave it some hell today, now I notice I'm getting a slight grinding like sound from the supercharger I never noticed it before, is this sound normal when you put a 2.8" pulley and 60# injectors in? It’s not relay loud but I noticed it sounded different from in the cabin of the car after I installed the kit?

 

Is the noise at idle? If so thats typical of eaton blowers they generally operate not so quite lol. Sounds like rocks being juggled. If its in boost thats probably just the whine of your blower.

 

no it’s not the rock or marble like noise, that I have heard before, you hear it at idle and while the charger is winding it’s more of a constant grinding like hum

 

Is the belt properly aligned? Check for shavings by the snout. Most likely its just the nature of the blower (gen 5 and below)

 

yea belts good, I hope nothings wrong....
