As you all are probably aware, elevation really strangles our cars. I live at about 6,000-7,000ft in Utah. From what I've heard from my friends, stock LS1's are running low 15's at the track in Salt Lake City. Is there any way to even partially make up for the terrible elevation besides doing more mods? If this hasn't been talked about before, hopefully it will spark an interesting discussion.

Run nitrous, and I'm serious.

Nitrous was originally invented for use on WWII aircraft to enable them to fly at higher altitudes, or else they'd stall due to how thin the air was.

Hope this helps

Nitrous is good.

Vortech and ATI make some good compressors themselves. Called Superchargers. For the more adventurous ... there are some Turbocharger kits out there. Airplanes use these as well.

Head on over to the Forced induction forum ... there are lots ideas over there. Also go to LS1.com, they have a good board there also.

Forced induction would be the way to go. You would see huge gains if you installed even a small Vortech unit on your car, because it is force feeding your motor and it won't be affected much by elevation.

I say if you do that you will go from your low 15s to high 12s.

Thanks for the advice guys. Nitrous or forced induction are on my list of planned mods for the long term, but I was just curious if there was some "simple" fix. Ah well, time to start the bolt-ons and work from there. Thanks again.

You can ask just about any ricer (most f-body owners don't use it) for a elevation correction table. From my understanding it is just a table that determines what you would have run if you were at sea level.
