Venturi vacuum pump

[FattyBoomBatty]

I think you are extremely biased against the Krank Vent for no good reason. It's been around a long time. Long enough for people to find out the good and bad aspects of it. But people still use it. Nothing non-factual has been stated about the Krank Vent, so why are you claiming that?

You said earlier that size doesn't matter, it's how you use it. Well, I don't know if you know this, but when you're talking about airflow, size matters ALOT. Why do you think people put larger turbos on their car when they want more power? Because they flow more. You can't tell any of us here that a vacuum line will be able to keep up with the rotating assembly pushing air around at 7k rpms. That's why people install large diameter AN fittings with a REAL vacuum pump driven from a belt off the crank.

This is a chincy, hardware store "bandaid," as you labeled the krankvent, that you are peddling here for 30 or 40 dollars. I can buy that same junk at ace for 10 bucks and steal some vacuum lines from a junkyard for free.99 and it'll work just as good or better than yours. So what do you have now?

Excellent comments Fatty.

iceminion, no offense but I don't really like your little venturi thing you're peddling here for two reasons. One, this is not the place to sell stuff. This is the place to show how you built it, show how it works, etc. Two, I don't really like the design. The KrankVent's are simple and they do the job. This venturi apparatus you have fashioned here seems insufficient to fill shoes of what needs to really happen.

I am editing your current post as of now for pricing, as it really does violate the rules. I let it fly initially, because I thought it was a neat alternative. Now with your fierce backlash comments towards others that seem to come from nowhere, I simply ask that you cease and desist. If you want to show the parts you used to build the thing, great. Otherwise, I think I'll order some KV's. :P

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.

Seriously dude, just calm down and take a step for a minute. I think you've missed half of what I've said and are getting way to defensive about your product that nobody has said an ill-word about. If you don't want discussion going on in your tech thread then made a for sale thread instead.

How does the Krankvent work under boost on a car with some blowby or a loose built big HP engine? Once the vacuum from part throttle cruise is gone, where does it get more?

[Kracka]

Thats why you need to save some for later...duh Shane!!!

Actually, my assumption has been the intake pipe. I have no idea how much vacuum this creates, but worst case scenario its no different than running a crankcase breather filter. I would imagine there is some decent suction from the turbo though if the air filter or MAS pose any restriction what so ever.

[Shane@DBPerformance]

If you run it to the intake pipe, then you would have some vacuum. A decent sized turbo can suck your hand in from a couple feet away.

Who cares, turn up the boost!

LOL! Someone's new sig, I forsee :D

This thread is doomed :pc:

Nice idea iceminion.

[sleepydsm]

So what about a GM MAF equipped car in suck through configuration. Would your route the vent side line to the intake pipe AFTER the MAF, before the throttle body?
