[QUOTE="KCTurbos, post: 1537904, member: 13852"] Actually... that is why dyno's have "corrected numbers". Because you can't keep all variables exactly the same even 1-2hrs apart. The "corrected numbers" take into account temp, altitude, humidity, etc... all the variables that change. It uses a fancy formula to "give and take" as needed to keep the baselines the same. It is pretty accurate from all of our testing. Just last week we took a truck that we had on the dyno 8 months ago when it was much cooler out, swapped around turbos a bunch of times, and went back to the original testing turbo. We are about to test something other than turbos and wanted to make sure our baseline was still correct... but who knows what can happen with a truck that is beat on over 8 months and did not want to throw off the data. So we put the original turbo testing turbo and went back to the dyno this week... EXACT SAME power curve and within 2 hp (which is negligible and can vary more than that just between dyno runs). Long story short... that is why we use "corrected numbers" for all of our testing because it keeps a baseline and allows us to test things all year round and not have to worry about having he "exact same conditions". Granted that is also why sometimes "corrected numbers" don't align 100% with track numbers. I know this goes contrary to popular "internet" belief... but Dyno's are much better for testing products back to back because they can take these variables into account. They can also monitor and catch much smaller details. [/QUOTE]
