The car has automatic transmission, and they tested it from 85km/h i third gear, and then they put the pedal to the metal!
According to the owner the car is equipped with original exhaustsystem, original engine mapping and modified air-intake, the car was imported to norway a few years ago..
Has been driven on german roads before!
You know, it's autumn here, appr. 10-17 degrees C.
I believe those numbers!

But the real power loss can be higher than 20%? (edit: I ment could be less than 20%..example: 15% powerloss instead of 20% gives 194bhp..)
He didn't take a dyno run before the rebuild. so we don't know what kind of numbers he had before..
I will take my on a dyno-run before and after i've found my lost power! and I will present them here!
