elevation question for dyno and 1/4 times suppose a car is making about 490rwhp at 5500 feet and is then brought to sea level. About how much extra power would that free up? also, if the car is currently doing about 11.9 at 118 mph in the 1/4 mile...what do you guys think the car could do at sea level?
thx

If it's forced induction, it won't make as much of a difference, but for NA, use the calc from this:

At standard temp and pressure, you are looking at a loss of 21.6% power @ 5500ft vs sea level, if it's NA. If it's forced induction, it depends on how much boost, IAT's, etc.
Also is that 490rwhp corrected already? If so, you're dyno is going to still read 490 at sea level, but your times will drop a lot.
