Following on from debates about 'bottoming' studs and the new generation of Cosworth Subaru Head Studs which have a base feature we are starting to model the threads in the case, the stud and the head joint.

If we produce a good 3-D model we can export it ANSYS build the preload in and 'warm it up' to look at the stresses.

One thing I have little or no data about is the depth of the blind stud holes in the various generations of engine case and the variations.

I have early Aluminium Cases, early mag cases, 5R/7R cases, Carrera 3 cases and SC cases but I don't have any 3.2 cases.

has anyone every made any measurements of the depth of blind hole and the depth of thread?

Any data would be helpful.

Thanks
