Paul, I did a search and found your post specifying the lengths of a .7, a .8, and a 1 bar spring for a 965. This info will probably help me identify the spring in my wastegate, assuming the 965 and 930 use the same springs.

Andy, thanks for the data point. My exhaust system is stock, but there may be something, similar in nature, going on that is influencing my boost. I just need to know what spring I have installed to establish a basis on which to proceed.

For future needs, I’m really interested in an accurate spring outside diameter, wire diameter, and the number of coils in each. If no one has that information, I’ll probably just order a set of springs and measure them. I’m sure the springs will be of use at some point in this project.

After I get this info together, I’ll post the dimensions and actual spring rates for those who may have a need to know them.

Thanks again for your help,
