Z-Gad said:I don't understand how you can use "corrected" numbers and call it any kind of record <shrug>
I don't doubt you are making some good power, because you are, but showing uncorrected data and stating altitude would be more valid for me...
You probably made an uncorrected record with that turbo for your altitude, so congrats
just my .02
John Reed said:The correction factor will artificially skew your numbers high, which is why you cannot use or compare "corrected" numbers for turbo cars when you are dealing with elevations above sea level. They simply do not lose horsepower at the same rate as a naturally aspirated engine will due to the fact that the turbo can simply spin faster to keep the boost the same. The turbo engine will eventually start to lose power, but only after the turbo is tapped, and this will vary from setup to setup. This makes it impossible to accurately and fairly apply a correction factor.
So the only really fair or accurate way to have a record of any kind would be to dyno all cars in question on the same day and on the same equipment.
Anyway, congrats on getting your car dialed in and no matter what the "numbers" say, I bet that thing is fun to drive! I really like the 74mm for a street car.
