engine making more valve knock with new turbo

[BBowers]

I just tested my new 62/14 htb2 today, and I am a bit puzzled as to why the engine seems noisier and why the valve knock is pronounced on acceleration. Truck seems a lot stronger, and the whistle is very awesome! It is a bit louder than I wanted, but I'm sure it will grow on me. I have no idea what kind of power I am making now, but I also installed a FASS 150/150 a few days ago. Haviing trouble with the fuel return manifold hose connections leaking... anyway any ideas? EGTs dropped from 1523 on extreme on my tripledog down to 1260! YAy!

Valve knock? maybe it's combustion knock, and if you have less smoke, it's burning stronger, so it will be noisier. Fuel pressure also affects knock.

Can someone define " combustion" or fuel knock as some call it? Mine is almost irritating since I had injectors done, get rid of one noise, picked up another! #@$%!

I don't really think anyone has answered my original question. Why is this hapening more often on TDR? I am thinking maybe it is getting to be time to go to another site.

bigger injectors do that

So nothing to worry about then... outside the strange looks I now get when driving alongside someone.

Oh, is that what it is? Thought maybe it was the black smoke storm I left them in at the last light! :-laf
