Nitrided cranks

[what year is it]

If you were going to build mainly a street engine would it be necessary to use a nitrided crank?

Story:Old Porsche/Mercedes mechanic trained as an automotive engineer in Germany told me about the value of nitriding once.The Lead mechanic in his shop Gunter,removed a crank from a Porsche engine that had the rods burned onto the journals.Gunter went to throw out the crank and get a new one to rebuild the engine.My friend asks if he can have the burned up shaft and Gunter says "OK,but it is trash!" and goes off in a huff.My friend knows better from his training and takes the crank to his bench where he takes a cold chissel to the rods and cuts them off the shaft.Underneath is a perfect set of nitrided rod journals on a very expensive Porsche crankshaft.Guys like free stuff!
CB performance posted the specs for the SuperRace stroker cranks they sell.The independant analysis showed good penetration depth of the nitriding process.The Century brand was compared in the same spec sheet and showed very thin penetration of the journal.Not all nitriding is equal.Your call.

Nitriding is far from the same...

Most companies use a "nitrocarburizing" heat treat and refer to it as a nitride process- Its not the same.

I have my cranks Ion Nitrided and we have seen some of them that have been turned .010 and the nitride was still present. The guys that do this for me work with Diesel engines where Nitriding is the only thing that keeps bearings alive.

Its not a must for a street engine, but man have we seen some great things come from Nitriding , especially when running a Pc2 coating on the bearing...

I wonder about Revmaster cranks? These use to be what CB sold up until the late 90's.
