Project S2000: Part 27 – Building the F22c for Turbo Boost and Manifold Test Fit

Holding the big end of the connecting rod together are Carrillo CARR fasteners. The alloy of the CARR fastener allows for an indefinite number of torque cycles when using the stretch method for installation. What this means is the fastener stays in the elastic region of deformation of the alloy, so there is no permanent yielding. I don’t plan on ever taking this engine apart again, but I like over-kill building for reliability.

Check out the generous fillet radii all over the rod to reduce any stress hot spots. To ensure the quality of each rod, a Rockwell hardness test is performed to make sure the heat treatment procedure resulted I the proper material properties. Each rod also goes through the magnuflux procedure to check for any possible flaws in the surface. Cracks propagate from surface imperfections which are stress risers and no one wants cracks forming in their connecting rods.

Howard has installed the pistons onto the rods and checked the piston ring gaps.

For the bearings, we went with King Racing pMax Black. I actually had the opportunity to attend a tech seminar with the lead super genius bearing guy at King Racing. There is a LOT of detail and features that go into engine bearings. A big thanks to Real Street Performance for getting us a set of bearings; the bearings were very scare in supply and they were able to find a set for us.

The main crank bearings are installed with lube in preparation for the crank install.

Howard is using his usual delicate touch installing the crank into the block.
