CONTROLLED CONFUSION

Is it worth it to send parts out for the deep freeze?
looking maybe to street a big block 10:1 compression H.
looking to get 100,000+ miles without a tear down...tune, assembly etc factoring

i drive 45,000 miles a year

it has something to do with the fact that when it's frozen, all the atoms ae packed in very tight and get aligned with one another, creating a more uniform structure.

subscribed. i'm definitely interested in this. i wanna hear from people that have real experience w/ cryo treated parts.

same here, I've read about this numerous times, but never seen any results in the honda world. Who knows, maybe cryo treated sleeves could be the new hotness..

Cryo treating the sleeves would make boring them alot harder which in turn would cost you more money. Pistons and transmission gears maybe but I wouldn't do my sleeves.

ok but what the whole deal with it?
do i blueprint and balance the entire rotating assembly before or after the treatment?
does it affect tolerances?

Bullshit. What machine shop is going to charge you based on something like that? "Hold on here, let me test the rockwell hardness of your sleeves and then I'll have a quote for you in a minute" Yeah right. And as opposed to replacing the sleeves entirely? Let's say you could get the stock sleeves to last reliably at 600whp, then what's cheaper?

What are you calling reliable.... a race season he says he wants this motor to last 100k miles no way on a turbo honda. I recant my former statement cryoing everything would be a good choice if you have money for it.

You would have to balance, blueprint, and assemble everything to check all of your clearances then tear it down treat everything and assembly again. For the record the machine shop won't charge you extra for boring your block but it does make the process alot harder. You would get it treated after you bored the block anyway.

give these guys a call they can answer all of your questions

its a good process to do. listen to the first poster. usually when things are heat treated they tend to get brittle and more prone to facturing
