Don't know where you came up with that but the crank case breather on both the H22 and H23 takes in air on it's own. It does not expel air into the intake pipe. So you didn't cool down your engine or intake temps any. How would this cool your engine temps anyhow?<font face="Verdana, Arial" size="2">Originally posted by Merlin1xx1:
the crankcase breather was probably the best $10.00 investment i've ever made, it has helped cool down the engine and the intake dramatically if you only have $10.00 to spend this is what you should do. </font>
I'm not trying to flame you but how in the heck can the crank case transfer heat to the intake if the crankcase sucks in air from the intake? Sorry but all intakes heat up when you run the car, it's just the heat under the hood being transfered to the piping. It has squat to do with the crank case being hooked up to the intake. My intake is as hot now as it was before I but the breather on. Heat cannot be transfered upstream, it's physically impossible.<font face="Verdana, Arial" size="2">Originally posted by Merlin1xx1:
the crankcase breather thing.
when i put it on i expected absolutely nothing from it, i figured id put it on for cosmetic reasons, and because if i spent another $10 i got $50 off of my total purchase...so, i put it on. as far as the intake pipe not heating up as much, there is a transfer of air from the head to the intake pipe, yeah the breather is supposed to draw air but it does a pretty good job of getting the pipe warmer, hook it up and check it out, its very noticeable, i'm talking noticeable enough that you can put your hand over the intake pipe and feel the difference. try it out.</font>
As long as the PCV valve is working correctly and you are not running any sort of FI the valve cover breather will only suck in air. You can run a simple experiment to verify this. Take a balloon and put it over the outlet on the valve cover. I did it and under no conditions could I get air to go into the balloon. A little may leak back every once and a while but I garuntee that it is not enough to make an appreciable difference in temperature.<font face="Verdana, Arial" size="2">Originally posted by Merlin1xx1:
heat not being able to be transferred upstream is like saying current cannot backflow through a circuit. yeah in theory it sounds nice but it just isn't true. is the crankcase sucking air in, yeah i think thats the theory.</font>
