will this increase their logevity or durability?
ive heared that if the part is used int he motor then it has less of an effect on the part

can anyone provde any info?

 

it would help definately, my chassis guy reccomends it for almost everything

 

here's a site i found...
http://www.onecryo.com/

 

wasn't there just a nice discussion about this, maybe a week or so ago???? hmmm
*EDIT* https://honda-tech.com/zerothread?id=631471

try that!!!!

1) For all you Tech-school grads out there, what exactly is involved in a cryo-treating process?
2)Does this process actually increase the strength of internal parts, or just their ablitiy to handle thermal loads?
3) What does a process like this cost?

 

Put the money towards CP pistons and I guarantee you'll make more power.

I've seen a couple times so far.

What exactly is done to the CP's you and MAX_CFM modify?

 

It sounds like a good idea, but I think it would change everything (like tolerances) that came up, and how would you know what tolerances to spec everything too?

CP pistons make power. I know that for a fact because we use them in motors we build. Straight out of the box they are pretty killer.

 

Yeah, I know they make power, but on EF-1.com I saw that you and MAX_CFM were going to rework some of them.....

 

All I know is that if you cryotreat you will have to recheck clearances cus they change by a little bit...

By cryo-treating thepart is frozen to almost 0 degrees kelvin, where all the atoms almost stop moving. It makes the grain uniform and increases strength.

I've done it to handguns and i'd say it's worth it for motor parts but i dont have any experience so i can't say for certain if it's a good idea or not.

Yeah, alot of what we do is reworking stuff to what we like it to be.

 

Rewroking? Do you mean hand finishing the pistons by smoothing out the sharp edges? Fly cutting the reliefs (which I dont recomend)? Coating them? Not much else you can do other than that without effecting the funcionality of the piston...

Hand finishing the tops of the pistons, smoothing out the rough edges is something that should always be done before dropping the slugs in the block... It will slightly reduce the chances of detination... every little bit helps

CP's are good but there isnt anything that seperates them from any other piston other than weight... They are made of the same 2618 alloy as JE, Wiseco and Ross... The dome configurations and designs are fairly similar as well... They are very light though and that does help in making some extra power but than again so are JE's and the IB spec line... Its all personal preference really...

So you are saying CP is no better than JE, Ross, Arias, Probe, Wiseco, etc.

I work closely with CP and help where I can with testing and such. I also know some of the current politics so it doesn't suprise me to hear statements like this.

There will be some new dish designs that CP will be coming out with that will improve power. This will be CP new line of 9.7 compression shelf pistions with a hem-spherical dish that MAX_CFM used in NASCAR to pickup nice HP gains in a sport where teams get excited about 1-2whp.

There is alot you can do reworking pistons to make power
Every cup team Does it becuase it makes power
There are cetain things you do to the rings and to the pistons
I like the Wiseco strutted stuff then I put a small pin it them
and there really light..

But hay what do I know

 

Im not saying anything along those lines... We carry CP as well...
So like I said... "its all personal preference"

Yeah, what do you know??? lol

Hey man, I saw one of your heads up close recently and I have to say...

NICE WORK!

 

Who's is it ?
Pro car or street car

Just wondering

Some guy at a V8 shop was getting his head flow benched and told me it was an RLZ head... Im assuming it was a for a street car... Didnt stick around for the results but I gotta chance to check the head out...

It was a B16 head... If that was your work it was nice, very nice!

Not really sure all of our heads have a serial number on them
I have a book with all of them and flow numbers
But if it looked really good and flowed awsome then
It probally was mine

 

Hey Rocket... Isnt EF-1 Splitsville?

I like that, If it looks good and performs good... yup, its mine alright...

lol, nice...

There have been some major changes from a decision I've made.

 

CP Pistons are pretty impressive looking, quality of the casting-wise.

I wasn't that impressed by the off the shelf dome designs, compared to an Endyn or IB Spec Piston. They definately needed some re-finishing.

Heres a quote from Brad @ RLZ...

"Yep Wiseco Makes our pistons

I have used everyone for pistons

And Wiseco allways makes the big numbers"

I agree, our dyno sheets and customers agree as well... IB, RLZ and ENDYN... 3 Big names all which use Wiseco... That should tell you something

IMO, one of the best pistons available for Hondas and the most reasonably priced as well.

Keep in mind weve used CP, We were a Wholesale distributor for them for a while. CP is a good piston yes, but it all comes down to what I said before...

Personal Preference

The major players out there right now pretty much all prefer Wiseco...
