Vortech cold start up warning:
In order to achieve the low noise level
superchargers, Vortech specifies manufacturing
procedures that call for minimal internal clearance.
These precise tolerances however are not
conducive to temperatures below 25° F. Therefore,
storing the vehicle in a heated garage and/or
employing the use of an engine block
heater/aftermarket engine blanket is required when
the vehicle is subjected to a "cold startup"
ambient temperatures below 25° F. Failure to
comply with this may result in immediate
supercharger failure and invalidate the
I may have found out exactly WHY Vortech carries this warning and the Procharger's do NOT.
I have spoken with BOTH companies. Vortech EXPLICITLY told me to follow their guidelines or they will not cover ANY winter causes of failure. Procharger confidently denied such claims for their superchargers, only to allow to start up and idle for a few minutes until operating temperatures.
*V3 model shown
Helical gears make them more sensitive to cold weather start ups?
*D1SC model shown
Straight cut gears, biting into one another vs meshing (helical)
We all know Prochargers make a lot of ruckus at idle, but who would have thought it would contribute to their sturdiness in extreme weather?
Never race your engine and ProCharger
supercharger when your engine is cold. Allow
the water temperature to climb into operating
range for several minutes before driving above
2,500 rpm, to ensure adequate oil lubrication.
