Parts is Parts -- Supercharger

Recommended Posts

I have purchased a second new OEM supercharger for the STS-V. The STS-V uses a custom Eaton M122 style superchager. This was the last of the 5th generation superchargers from Eaton before the new TVS line the 09+ CTS-V uses. I also think this will make for several interesting articles and experiments.

My goal with the new supercharger is to make it easier to swap some modified parts info my V and still keep the original setup intact.


The ebay superchargers were purchased as a lot at the end of the V manufacture, and have been on sale (larger quantities available) on ebay a while. I just ordered it, so it won't be here for a while. This photo is from the ebay ad.

Next upgrade for my V will be injectors to get my duty cycle down a bit. I don't expect that to add power, but will need a bit more injector for other mods.

Those injectors will add reliability. The reported duty cycle of 92% is too close for comfort. A few tens of milliseconds running lean at high boost can ruin a good day, although the PCM will probably prevent damage.
