doesnt the amount of blowby depend on the condition of the motor? a relatively new motor, with properly broken in rings, shouldnt have nearly as much blow by as an older motor right?

and couldnt just using a bigger can, and larger filter with more surface area help crankcase pressure escape more efficiently?

I just installed a small catch can setup like the one posted above, and tapped a filter onto the top of the can, and Im curious to see how it works out on a brand new setup.

The condition of the motor definitely has to do with it, but the power level of the motor has almost as much to do with it.

Yes, but I can't find the .pdf file they sent me. There was nothing in the results that would indicate a problem.

It's several numbers, and can not only give you an indication of how well your oil is doing its job, but the health of your engine.

How can you argue with a guy that's been in the scene so long plus, are you running 9.xx's??

I make no where near the power tony1 does nor do I run times even close to what he does. The fact is just because someone is faster the someone else does not mean they know more. ( I am not saying I know more then tony1 I am just saying times are not directly related to knowledge.)

tony1

I guess i'll ask this, what to you hope to achieve with a catch can setup?

Bizarre

Shhhh, let them debate Lots of great info in this thread.

Thanks guys for all this information

tony would you post up the pictures of your catch can setup?

What setup would you consider good for daily driven 500WHP motor, than again i won't be using that power on a daily basis. What i mean is what is reasonable for a daily driver, because i'm not going to change oil every 2000 miles.

tony1

Check the other post for my pics, right next to this one. The endyn kit is good, but i think picking up from the front of the valve cover is better than the back of the block.

turboc1

so if you vent from the valve cover do you still need to vent from the back of the block? what size lines are good for venting out of the valve cover?

tony1

The more ventilation the better, until you get crankcase pressure down to 0 psi. How much power there is to be gained, i don't know, but i know the lower you get the crankcase pressure, the more power you will make.

I'm not saying it's directly related, but since he is running that fast and has been in the scene for a while I'm sure he has gone through a lot of trial and error and has found out what works best.

Discussion is good though, it brings up new idea's and thoughts on the matter which in the end should bring a more refined solution.

tony1

I have tried a lot of different things over the years, both with the endyn setup and with custom stuff. I'm not going to go into all the details on everything i've done and tested, it would probably take a while. lol

I am guessing this question is aimed towards me. The reason I chose to run a catch can set up is due to many reasons. First off Honda did not design the B series engines to undergo forced induction. This means when using a turbo/supercharger the stock PCV system is essentially useless since now all the places where blowby was supposed to be dumped due to vacuum is now pressurized with boost. Also a catch can set up helps reliability by saving the ringlands a lot of stress. High horsepower hondas have a good chance of breaking the ringlands. Not only that, it looks nice and frees up some room.

If I had to choose one I would say venting the block is better, but like tony1 said the more the better.

wicked2night

Tony how much venting would be necessary on a b16 making close to 500WHP, the valve cover and the block? The car will be daily driven but not at 500WHP daily.
I'd like something effective, but not changing the oil every 2k miles or emptying the catch can every day.

I will now go and look for the other thread and your pictures.

Why would oil over flow from the catch can? Are you asking becasue this setup doesnt use the drainback feature? If so all you do is empty it every couple of weeks. If you use the drainback feature by tapping into your oil pan your just going to contaminate your oil and have to change it more often.</TD></TR></TABLE> I dont see how the drain back can hurt your oil , what do you think the honda black box does ??? drains it back , mine has ben draining back for over 2 years now with no problems , and also to the blow by on a built motor , if you want to make alot of power and want it to last most builders run a bigger ring gap , to help out with expansion at higher heat levels from the added levels of power

for those to lazy to look for these, they are tony1's catch can.. i am looking to have him do this setup on my car as well..

good thread

but hey you cant all reference tony1's setup his is ballerific!

A standard front of vc vent or rear of block venting will work fine for 90% of people, only super heros like tony get super sweet custom fabb'd cans like that

Something to note is you will get less can filling if you run your venting off the front of the VC becuase the fittings are the highest point on the engine so you mostly get pure vapors and oil sloshes back on acceleration so using the rear of the block fittings will give you more filling/faster

I use the back of the block jus cause i need someone to weld the fittings on my vc

edit: wooh tony your run 4 off the vc and 2 off the block? your really letting her breath! What size are those lines? -10an?

tony is dead on here, i have the endyn catchcan setup on my 81.5mm bore block last year, with a tight ring tolerance. I never had the filter puking oil.... I now moved to my sleeved block with .19/.24 ring gaps and at 14psi, no issue, as that's just 400whp. once i cranked it up to 25psi, hello oil everywhere.

now i'm adding a second moroso can and running two -12 lines off the valve cover off the front of it and keeping the moroso setup in hopes of having less oil all over my firewall.

and for people that don't drain back...you'll be filling up your oil and draining the can after 2 good passes.

my new block has 800 miles on it, 1-2% leakdown, and 185 compression on all 4.

i have the greddy catch can with no breather, is it still safe to follow all the steps in this diy in installin it?

no, you need to read my thread (in 1st post) it has the DIY to convert nonbreather cans. Basically add a fitting on the top of the can and ur good

I had a quick question regarding Tony1's setup?Lets say that you are using the Endyn/Z10 setup and want to use the front of the valvecover as the inlet for the system but you have the can mounted lower than the fittings on the valvecover then where would you plumb the return fitting?Thanks in advance

Timmay

where are you guys draining the catch cans back into? are you tapping the oil pan?

tap into the lines off the back of the block for the endyn kit. those ports in the block lead ultimately back down to the oil pan.
