Does the cryogenic process actually increase the entire stress/strain curve including the proportional limit and yeild point or does it just increase the ultimate strength or the nominal rupture strength? The reason I ask is if it doesn't increase the proportional limit or the yeild point then it is only going to keep it from breaking, or increase the ultimate strength. If it only increases the ultimate strength than it doesn't seem that worthwhile considering that the yeild point would still be the same, so if you go over the yeild point whatever thing you have will be out of spec. While it would be nice that it could handle a greater force you wouldn't want to raise the working stress limit cause you risk permanently deforming the object.
Do you guys want me to make a thread for when I do my buildup? It's going to be a PP turbo, with much aide from Banzai. Keep up the good work buddy, lets see pics of the final airbox design, and the slashed up aluminum TII hood. https://www.nopistons.com/forums/pub...#>/biggrin.png - Hand Cryo freezing doesn't do jack all. Only good it does it cleans any biological agents off the part without affecting the temper/heat treament of the part. THe phase transitions stop at around 100C, almost nothing happens below that temp. |

You actually bothered to waste money on cryo treating? I thought u were an engineer. Brand new S4 LSD? wow big $$$$
Aaaaaah you book types are soooooo easy to reel in! Spent the evening at SDJ dropping off the ring and pinion. Gleened a lot of info from Stan. Verified the parts I needed to order from mazdacomp with him. Diff will be ready next week. We had a long and lengthy discussion on vrious coatings and the pros and cons of each. https://www.nopistons.com/forums/pub...IR#>/smile.png Btw, the Cryo was not the primary treatment. But the shop I use packages it with another coating service. https://www.nopistons.com/forums/pub...DIR#>/cool.png |
And the Airbox design may change yet again..............

Today I had an informative conversation with Mr. Hanover, and commenced to redesigning the intake. Cup of tea, some kick ass music from SIRRIUS on the Shop Surround sound system, a quick trip over to the bandsaw..........and VIOLA`
The beginnings of the new intake. This will give me the ability to vary the length of the runners very easily!!! This was only the first mock-up so everything is taped and squee-jawed into approximate positions. https://www.nopistons.com/forums/pub...1047683664.gif [attachment=27615:attachment] [attachment=27616:attachment] |
A little close to the alt? looks good though.
|
very nice, where did you buy the aluminum U bend from?
|
That one is mild steel, for mock-up purposes. Cheaper to hack up for experiments. The AL will come from burns or the place in MI

Lookin' good banzai. Can't wait for some video. Hopefully some dyno runs.
