After several thousand miles my valve springs have lost zero lbs of spring pressure from the initial 160 lbs of seat pressure. They normally lose 10 % after being heat cycled, so they should have been around 144-145 lbs. The cylinder heads were powdercoated and had two problems. One they took 23 minutes to melt the powder instead of the normal 15 min. Two the powdercoat didn't stick to the heads like normal and wanted to just flake off. Lastly the valve guides were very difficult to ream out for the new Ferrea 5/16" valve stem's. They ended up wearing two of the reamers out and a good portion of the reamer on the third one too.

it is where you cryogenicly freeze the block or parts. it changes the molecular composition of the metal, thus making it harder/stronger, and less likely to break under extreme conditions.
I have cryoed Block, rods, and crank in my GTP. have had no problems with it. I am doing the same to my drag car now as well.
many racers back when racing got started, decided to try it, now many people have forgotten it, or just dont care, but still many people choose to cryo parts. Many Die hard racers cryo them as well. I view it as an added bonus/insuranc if you will. if you are making extra power....whats 300 to help make it bulletproof.

I've thought of cryoing a block, but I've never heard of anyone doing it. Lots of racers do it on the crank, rods, pistons, etc... I'm sure there'd be benefits, especially on an FI motor.

It makes stronger even stronger. Just find an in with a cryotreatment facility that does a bunch of oil-related business and just see if you can add stuff to the batch. You don't gotta pay big bucks to get it done like a lot shops lead you to believe.

would it be better to micronite it first, then cryo, or cryo then micronite?

Which is stronger?
Which is stronger?
-grey cast iron--97%
-alloy steel--131%
-aluminum--about 50% from what I have seen

I have a serious question. Now when you Cryo parts made with different methods does it affect the parts differently?
Example:
The block won't really change dimensions because it is cast but the rods will because they are more pourous powder metal.
Also, how do the dimensions change if you decide to have your entire motor done? Extra machining involved afterwards?

HR&D in Clinton Township MI does most everyones around here. I have had good luck with it on my engine parts. Mark can answer all your questions, let me know if you can't find the contact #.
