Venturi vacuum pump

[iceminion]

The KV's create a vacuum in the crankcase (even at idle). Does the air "woosh" into the crankcase when you pop your dipstick? It does with the KV's. The KV's are one-way valves similar to a PCV, but unlike factory PCV's they do not leak boost into the crankcase. You put one between the intake manifold and the factory PCV and one on the valve cover breather allowing air to only escape but never enter. Doing this increases engine efficiency by reducing drag on the crank/pistons (more power, better MPG) and also helps the piston rings seal better reducing oil consumption. These will also fix symptoms such as leaking gaskets and dipstick pop-out similar to your pump.

Everything you said:
1. Makes no sense.
2. Is incorrect.
3. Has no factual evidence to back up your claims
4. Has nothing to do with the topic.

If you want, I can tear your paragraph apart piece by piece. I would love to write a ten paragraph explanation of how everything works, http://xkcd.com/386/

But instead, lets get back on topic.

UNDER BOOST: air needs to be forcefully removed from the crank case drawn through the (almost inadequate) crank case vent.

this can be done by:
-sucking air into the turbo (not desirable)(ineffective with large turbos)
-using an electric pump
-using a mechanical pump
-using a venturi (i claim to be the cheapest/best bang for the buck)
-welding large AN fittings onto the valve cover (solves problem by offering a low restriction large hole for gasses to vent to atmosphere pressure)

depending on my schedule I might have some data collected this week, but after my math exam sounds more likely.

will have video(s) posted by sunday.

Kraka you are a cool guy, you would be even more cool if you were able to take it like a man and admit you have no idea what you are talking about.

Does it not connect to the same place as yours?

I really wish you had asked a more complete question.

In short, yes, it does connect to the crank case vent -and- to the pcv (basically a backup pcv valve)

but it does not apply vacuum at all, it only stops air from flowing INTO the crank case.....and seeing how the stock line goes to the turbo intake pipe (small amount of vacuum) no air would travel back up that line anyways.

this KV product will solve the problem of a defective PCV valve, but that is the only thing it will do, and for $110, I would rather buy a mitsu pcv valve and be done.

I feel like additional explanation is needed. I am not trying to push a product to make a huge amount of profit, I am offering knowledge that I gained through trial and error.

I know I am not the only one with this problem, I kinda wish more people would have chimed in with "yeah man, same problem here, can i buy one/tell me how you made it?"

again, just trying to help with a problem that is not really covered enough (in my opinion)

[Kracka]

I'm sorry that you don't like what I posted, I made no personal attack towards you nor did I say anything negative about the product you have made. I merely shined some light on a product that does something similar to the thing you designed, but goes about it in a different manner. I did not make any false claims and after re-reading what I posted I do not see anything that does not make sense. It seems like you are getting very defensive for no good reason and frankly I do not understand why.

You are wrong. The product I have linked does something very similar to the product you are trying to sell (without first becoming an approved site vendor I might add) in that it helps to run a vacuum in the crankcase which has numerous benefits. If you don't like it then fine thats your opinion, but do not come out calling me a liar and tell me that I don't know what I am talking about.

[iceminion]

please explain how a PCV valve (which IS the KV product) is in any way remotely similar to what my venturi is?

A PCV valve is either open or closed, like a gate, it does not generate any positive or negative pressure, it can only regulate pressure applied to it.

[Kracka]

Yes, the KV's are heavy-duty glorified PCV valves, I know this. They create vacuum in the fact they let air/gasses out, but not in. The difference between a KV and a regular PCV valve is the fact the KV will not leak air into the valve cover no matter how much boost you throw at it unlike a stock PCV valve. If you don't want to believe they work that is fine, but I can promise you that they do as I have personally used them as have MANY other people on both N/A and boosted applications with very positive feedback. I also think that you have it in your head that I am bashing on your venturi design which I am not and have in no way implied in this thread.

Similarities in the two products being discussed:
-less crankcase pressure
-no more dipstick pop-out
-fewer/smaller oil leaks
-smoother running engine

taken off your evo website that you linked above: " These devices are one-way valves that can stop 1000psi" http://evo.dejonpowerhouse.com/

taken from wikipedia: The Positive Crankcase Ventilation valve, or PCV valve, is a one-way valve that ensures continual evacuation of gases from inside a gasoline internal combustion engine's crankcase. http://en.wikipedia.org/wiki/Pcv_valve

So, again, the "Krank Vent" IS a PCV valve.

PCV valves do not create pressure or create vacuum.

in the picture taken from the website.

you can see clearly that one (1) of the "Krank Vent"s is inline with the stock PCV valve. (only makes a difference if your PCV valve is broken)
(This Krank vent is irrevalent and pointless, we are done talking about it.)

and the second(2nd) "Krank Vent" is to allow high pressure air to escape through the crank case into the atmosphere(high pressure to low pressure)

This second one will not allow unmetered air to be sucked into the valve cover and thereby getting sucked into the manifold.

SO the second krank vent will help with idle, and help keep the crank case maintain vacuum while at idle.

But here is the funny thing, this is not the problem, the car doesnt leak oil at idle, it leaks oil at WOT. The "Krank Vents" do NOT create VACUUM while UNDER BOOST.

[Kracka]

We obviously have differing opinions here and thats fine, but I can tell you from real-world experience the KV's work very well and help to eliminate the exact same symptoms that your product sets out to fix. Another thing, I am not a fan of how that KV is setup with the breather filter on it, I think a much better setup would be to run it to a catch-can and then back to the intake pipe.

Anyway, good luck with your venturi sales and I'm glad you are happy with the product you designed and are using.

[iceminion]

If your PCV valve is failing, The KV product is a great band-aid fix!
- and - or -
If you have (INTENTIONALLY BROKEN)modified your intake system from stock so that you have a breather on your valve cover(allowing unmetered air into your engine), the second KV will aid in restoring your idle.

Please, maybe I am over-reacting a little bit, but what you are suggesting is in no way related to what I am talking about, it is severly off-topic and your non-factual comments are cluttering up the thread.
