I have noticed a lot of HP claims are made at 5000 feet of elevation
I was thumbing thru a few diesel mags and a lot of the claims made by programmers are made at high elevations. Some are over 5000 feet. I was told that the best HP is always made at or close to sea level, in fact a lot of dyno will self correct to sea level. What is the deal with these claims? Do turbo;s make more power at higher elevations or is it just the companies that are making these products located in higher elevations?
A few years back my partner and i did extensive dyno testing for the owner of MBRP when he was working on building his line of ATV exhaust. We were dynoing at 800 feet elevation. The owner of MBRP made me some one of a kind atv stuff, it was a shame i did not have a diesel truck at the time.
