Does anyone publish a horsepower number for a Sierra 1500 supercharger?
Often, yes. Of 9 Sierra 1500 superchargers in our catalog, 5 publish a horsepower figure and 4 do not. Every figure below is labeled with where it came from: an independent test, the manufacturer's own claim, or an estimate from comparable hardware.
the ones that do
why the rest don't
Whipple's own listing describes "more power than any other positive displacement supercharger system on the market" at 7-8 psi but does not publish a specific hp/tq number for this kit - left blank rather than invented.
