Bean Posted September 13, 2012 Report Share Posted September 13, 2012 I was dropping my turbo gas head off at my shop... Sorry - just wanted to ask if the 89' head did in fact crack, and if so where? It's been mentioned that Eriksson repairs the same areas on either all four, or maybe it's the middle two... Curious if the shop you took it too will do the same - or if they had any tricks they do to stress relieve the casting. Personally I think cryotreating the head after the repair would be good insurance - the thought being any residual build up stresses that could lead to another crack would be dissipated since cryo is a good stress relief process as well. Sucky part about living where I do - anything neat like cryo has to be shipped way off to get done. Rabin Quote Link to comment Share on other sites More sharing options...
tulaweb Posted September 13, 2012 Report Share Posted September 13, 2012 Sucky part about living where I do - anything neat like cryo has to be shipped way off to get done. On the other hand you could just leave it outside on a mid winter night to get a pretty good cryo treatment. Quote Link to comment Share on other sites More sharing options...
Bean Posted September 13, 2012 Author Report Share Posted September 13, 2012 LOL - that's my only consolation when it's -40C (-57C with windchill), I tell my self the whole car is being cryotreated... Rabin Quote Link to comment Share on other sites More sharing options...
Bean Posted September 13, 2012 Author Report Share Posted September 13, 2012 Link to back up my cryo claim: http://www.cryotron.com/thermal-stress.htm I've seen cryo treated brake rotors on rally cars outlast untreated rotors 3:1, and on my Volvo which is kind of known to eat rotors my cryo Powerslot rotors look new wear wise.
