Nitriding vs Turftriding

Combating adversyty.
My engine builder suggested tuftriding as an alternative to nitriding the crank.

He knows his stuff and I searched on here but nothing came up. Has anyone heard of it or used it?

As I understand it is a similar process but not as hot. The surface finsish is also not as long lasting and while it is hard, the surface can be scrubbed off easily. This suggests to me that it is ok for short lived engines such as dedicated racers but might be a bit of a waste of time in a DD or a long term truck. For the record I don't plan on building this engine again so perhaps it isn't the way to go!

Also, I don't plan on more than 650hp so I guess the stock crank is up to it.

Has anyone got any experience with this process or any thoughts?

Re: Nitriding vs Turftriding

Tuftriding was a process employed by some OEM's on special high-performance cranks, primarily for the benefit of avoiding the stresses imposed by induction hardening. In Tuftriding, the crank is immersed in hot cyanide compounds, creating a tough, resistant surface that improves fatigue resistance. The hard layer in a Tufftrided crank is usually very shallow, only penetrating a few thousandths of an inch. One drawback of Tuftriding is the potential for warpage of the crank.
