Adjusting the IP to match the Holset

The 1.9 is running netter than it ever has. Still, I bought two of these and will mess around with some additional grinding.

I'n not entirely positive they will fit my 1.6 pump but they weren't too expensive.

Those should fit.

Aren't you a machinist? You could just make a cylinder and then drill and tap the top of it for a bolt rather than what Bosch did with the stud. You could even make it from aluminum until you find the profile you like then make a steel one.

I thought of that, figured I'd start with a "known" value. Who knows, it might be just right although it looks to steep at the beginning.

I believe the pin should only ride on the single long taper, not on the steeper angle at the bottom.

Yes, I figured the same, and it does appear there is a light and aggressive angles based on position.
I also ordered and received a new spring with a higher comp rate. It's running quite well now but I can just mark the settings and return to them if needed.
I'll wait for the pins to arrive and try both one of these weekends.

Where did you get the spring from? I could use one...

You get three and I believe it was around nine bucks for the package. Might be too stiff but they are easy to change. I am hoping that, combined with the new pin(s) I am getting from the UK, it will be more of a gradual increase in both fuel and boost ending in decent HP/torque and EGT's below 1200F.

The pins won't arrive for a bit yet and I'm waiting till they do.
