I hope Jake chimes in here.

Is Cryogenics really worth it for our engines?

I read an article stating Jake as the sole reseller of this service and he had it done to his company van,,,which in true form he went out and tried to kill the motor.
I read vlave adjustment at 15k intervals (he did check them every 1k, but no need to adjust????

Opinions and a cost estimate would be great.

We have had direct experience with cyrogenics in relation to our products and other type 4 engine components that Performance Cryo did for us. With our biral cylinders, the ductile iron became near unmachinable after the cryo process and we ended up destroying lots of tooling before coming to the realization that we had to do all the machining first, then cryo :-) As far as testing results on cryo'ed components, we were having camshaft issues with Shad's 2615 and we ended up cyro'ing both cam and lifters with the last set we put in and over a year and a half later, the cam looks just beautiful and the lifters have excellent wear patterns. As far as cooling is concerned, I had my 2L heads and all related valve componentry cryo'ed, but I have only 500mi on that Nickies engine so far (i also had the ports ceramic coated and the exterior of the heads coated with thermal dispersant). I'll tell you in 15-20k miles how the guides, valves, and seats look. And as far as Nickies are concerned, when cryo'ed, they should cool a tad better (might not be noticable), but it increases the strength of the aluminum quite a bit, just as good as going up to the next heat treat (T9).

Take care,
