Supercharge or Turbo at elevation?

Hi all,

I know the topic of SC vs turbo has been discussed but I’m wondering how much altitude impacts the performance gain? I’m in CO and I’m sure some folks on here have done it, what are your thoughts? Kit recommendations?

Elevation makes a huge difference. Turbo or super there's a lot of other variables that will impact that choice, either will do what you want. A supercharger you'll want to run one of, if not the smallest, pulley that's offered to make up for the altitude losses. A stock supercharger at 5000ft isn't making much more power than a stock truck at sea level since there's less base air pressure for the engine, plus the blower makes less boost, so really have to crank the blower rpm up to make up for compounding losses.
