youre arguing that a k03 will make 250AWHP though. youre crazy. it wont happen. its impossible, all the turbo is good for is a quick kick in the pants from the torque onset and a little midrange power. the turbine simply cannot keep up with the engines exhaust flow at higher rpms, the wheels and the housings are just too small.
-a k03 has no turbine efficiency when boosted beyond the stock settings(or compressor for that matter)
-the compressor map puts everything to the far left and down towards the bottom(which is great for low end grunt)
- heat. thats all the turbo produces at higher boost levels
- back pressure. thank the stock 1.97" mk4 downpipe and the 2.17" b5 downpipe, along with the terrible housing design KKK/BW uses for that turbo in all configurations
