Rod cryo question
Since I plan on getting my rods cryo'd, how imptant is shot peening too? I know WOP does it, but heck ART is about 30 minutes from me, so that means a lot shorter turn around time.
Also, is there nay benefit to getting pistons and other rotating assembly parts cryo'd too?

Cryo as much as possible! being in so cal you might be able to find someone that is pretty reasonable. My local cryo shop will do a whole engine for $400.
As far as shot peening goes... I would call WOP and see they have a shot peened, cryo'd set of rods on the shelf.
Here is a run down of what shot peening can do...
A study done through the SAE Fatigue Design and Evaluation Committee showed what shot peening can do for welds compared to welds that didn't have this operation done. The study claimed that the regular welds would fail after 250,000 cycles when welds that had been shot peened would fail after 2.5 million cycles, and outside the weld area. This is part of the reason that shot peening is a popular operation with aerospace parts.

for $380 a set WOP will weight match, magnaflex, shot peen, both ends will be new and then cryo'd..couple of big sled pullers on PSN (i have been PMing them a lot lately) told me the key to a smooth running longer lasting motor is to have it balanced...
