what does this help with. I was told it works great for lsvtecs and b20vtecs since. what are the advantages or what do you gain using this breather kit.

advanracing62

helps with crankcase ventilation, and pressure.

shouldnt a good breather kit tap into the block it self (ie. freeze plug) to properly let the motor breath. If the pressure builds up and comes out the spark plug holes then a breather attached to the valvecover would do nothing.

maybe an expert can show what a optimal breather kit should be like.

That is what the endyn breather kit does!

???

The reason I put mine where Endyn put theirs is due to the fact that it is behind a baffle and will reduce oil content in vapour. Also the higher in the motor, the lower the chance of oil content.......well this is my theory anyway

advanracing62

the Endyn kit does go into the back of the block, but it also ties into the crank case, and valve train vent system

thats a different breather set you are thinking of...there are ones for the block AND the valvecover...both with the same principle in mind....block is just used more.

id love to see how pressure "comes out of the spark plug holes" and then makes it way to the valve cover breather.

people that vent from the valve cover understand the follwing.
pressure is built in the crankcase, travels through the oil drain gulley-into the head and then out of the valve cover. the spark plug orifice has nothing to do with it.

the benefit to venting it from the block is that generally you are able to use a larger port rather than the small one provided in the stock valve cover...unless you drill your own ports in the valve cover..in which case, it becomes irrelevant.

more breathers the better...i say.

what would i gain if i upgraded my breater system on my motor? is there any hp to be gained?

right now i just have the valve cover breater open and nothing else.

rolow

What kind of motor?

if you are running a b20vtec or lsvtec and are burning oil you should look into an upgraded breather set up.

I am running a LS/VTEC its a b18a1 its a race car. I dont have the canister hooked up at the back of the block. I just have the valve cover vent open, on dyno pulls I can see some vapour coming out of the vent, my questions is what kind of power does the breather kit gain? Im not going to get it if there is no purpose to it.

cant i just have a line hooked up to the exhaust to creat vacume and pull the crank case pressure out of the block.

like this picture from Danny Trans website

I think one of the guys familiar with the above pic/setup said it was not working well that way for them.

MackSpeed-616

what kind of valve is that on the exhaust? a check valve?

yeah that is a one way check valve.... when i installed this crankcase evacuation it wasnt designed to make horse power like a vacuum pump... i was having alot of problems with the dip stick blowing out at high rpm and would spray my engine bay and header with oild and it looked like it blew up the motor every pass... since installing this system i dont have that problem anymore. Interms of HP gain.. i didnt notice anything dramatic but it didnt hurt my engines performance at all..... the stainless tube that is welded on the pipe is cut at an angel and has a slot on it to be effective... when i get some pics of it ill post it up..

aslo i only started having the dipstick problem when i started making more power... when i was making 220 and low 230 i didnt have the problem... so if you are not having problems with dipstick popping out etc. i wouldnt see a reason for adding this feature..

dmotoguy

for a 300 hp 2.2 b18c5 would you suggest using a set-up like yours or a vaccuum pump?

Tbone

If your going to spend the money to get that far, then do it right with a pump. and dry sump..lol

AZFABULOUS

We have experimented with an electric vaccum pump and to our amazement the pump actually made an additional 6 hp to the wheels all throughout the power band, but when the car started to get higher in the rpm band around 6800 or so the pump was not able to pull enough vaccum so the power went away but while the vaccum was present it did make a noticable difference. Keep in mind that this worked on our setup but may not work on others. Just a little food for thought.

what type of pump were you using? and make or modle #, do you think if the pump was able to create more vacume it would aslo aid in top end power? how was this hooked up to the block and do you still use it?

AZFAB1

We found the pump from a grainger industrial supply catalog, it was made by thomas pumps but I cant remember the model because we returned it. If you look online at there catalog you will find the pump, they only have 2-3 12volt pumps in their catalog so it shouldnt be hard to find. To the last question, yes I think that if the pump was able to hold a vaccum at higher rpm it would have made a difference. Oh and we just rigged it up to the valve cover breather, we were kind of skeptical if it was going to work or not so we didnt want to spend alot of time on it. I think it would be worth the effort to try finding another electric pump that would hold the vaccum at high rpm.
