I find the biggest difference with the K27 HF is that you have much better throttle control and far less of an on/off feel allowing you to feather the throttle gaining much more control over the car.

+5. Everything he said.

My dyno guy said "hmmm" in the preliminary pulls. I said "what?" - as you do.

He said "your turbo is making .5 bar @ 2500 RPM. That's pretty useful". Then he got out and added another strap.

Dunno how much is down to the GHL heat exchangers and how much to the K27/HF, but the car is completely different to drive.
'77 S with '78 930 power and a few other things.
