I thought this was interesting. On the hot rod and pro cars we always ran dry sump systems and I never saw one that pulled a vacuum on a high boost turbo motor, much less got down to atmospheric pressure in the crankcase. We'd usually see 1.5-5psi crankcase pressure. I setup a map sensor on the crankcase on my car to see how effective our catch can really is at big power, I think it's safe to say it's sufficient!

 

where'd you put the map sensor?

i thought about doing this on our race car but we need to get it down the track first

 

I put it on the back of the block, where the 1/8 NPT port is from the 'black box'.

 

What were the end results using the T1 catch can? How much lower were the numbers in comparison to ones in theory?

 

I must be missing a picture

DoD blocks most image hosting sites... can't see jack unless its attached via the forum.

 

Those are the results using the catch can, i won't run my car w/o a breather system to get that data. lol

That pic is hosted in the HT image gallery.

 

Gotch you. That is some very important data to know, so for us running 30lbs we don't see much compared to you. LOL Thanks Tony!! You rock..

 

I'm not seeing a pic and we dont block anything here at work.

I've still got nothing Tony, I think they still want you to use your own server space but won't tell us lol

 

dosn't show the picture on the link either

 

Yeah its just a blank page.

 

How about now?

 

still nothing

 

I asked this question before, do you see any diffrence in your last setup too the new one? I know you are using coolant in the new one. See any diffrence?

 

Go to the top right corner of this page and clink on the "Photo Gallery" and you'll be able to see the Data log.

 

we could see it now.

 

Dont you have to post a before also? How do we know theirs a diffrence?

No difference, this can is the same as the old one, the coolant is in separate compartments, has nothing to do with the catch can.

And no, I won't do a before test. You block off all the breathers on your motor and do a test at this kind of power. lol Make sure you have a fire extinguisher ready for when it blows all the seals on the motor out and the dipstick. There IS crankcase pressure there w/o a breather, that's a known fact.

 

At 45lbs of boost through a Honda motor you're definately going to see more than 0.1lbs of pressure in the crankcase without a breather setup like that of Tony's

 

Now if I could only figure out a place to put a T1 catchcan in my engine bay, damn accord.

Makes me wonder how well my setup with 2x -10an lines to a vented can are working.

 

I know i was just joking around. I was just curious to knwo what the presure was before and after...hahahaha

 

That is pretty impressive...now to check mine out and see where it's at. (When I get it done)
