Default Cheap blow off valve??

I see a ton on ebay for cheap, and then some expensive. I know the wastegate you dont want a cheap knock off, but the blow off valve is just a vacuum operated valve...nothing more. Is there a reason for the expensive ones? Sure you get what you pay for, but I see people running the cheapies with no problems. Whats the big difference that justifies the hundreds of dollars difference?
Thanks.

Dooood!!! The guy in the second one is charging double of what they are normally priced... Go to Go oogle dot com and type in Tial BOV and go to the shopping section. They are probably 10 or 15 different places that are cheaper by more than half....

There are lots of knock offs on ebay.Tial knock offs, greddy etc. Got to be careful .

Buy from bigger established company to be sure you get what you pay for.

Not really much difference on the more expensive ones. I upgraded my aps bosch blow offs for couple reasons.They are plastic which bothered me and they were too quiet and I like loud blow offs..call me ricer ! LOL

So went with pricey turbosmart supersonics. Still waiting on one stuck in Canadian customs it seems.

99.999999993% of cheap knock offs that are on CRAP-bay are made of inferior materials and workmanship. With CRAP-bay, you always get what you pay for.

I am all about saving a buck when needed, but with turbo related parts you don't want to skimp. AND TiAL is built in Michigan, if you have a problem call them, and low and behold you will get someone that speaks English, and will try their hardest to help you out.
Why support a company selling Chinese knock-offs of an American design???? You do get what you pay for.

And how and why would this matter on a simple vacuum operated valve? You get what you pay for yes, why pay $250. for a valve that a $30. one can do the EXACT same way? Unless you got other facts besides its better because it costs more you dont really have anything.

Like your windsheild washer lines, small rubber, im sure you could get some high pressure line that would hold 5000psi that would cost more. Yes its better because it costs more....but why would you do it when the cheap stuff works perfect for what it is?....?

Im wondering what could go wring with a cheap one and what justifies the price on the expensive ones?

I agree with like a wastegate, but a BOV? its not subjected to high heat and its a simple valve. Failure would result in what? Nothing really, because you'd know. And how could it fail? "You do get what you pay for" is obvious.... what more do you get besides english operators on stand by with the expensive one?

Why sit around on the Computer and argue about it?

Plain and simple you pay for the R&D that goes into a TurboSmart, Tial, Greddy, or JGS unit. You get a english speaking tech line. You get a proven Part. They didnt just go out and buy the competitiors and find a way to remake it with cheaper parts and then ***** it out on Ebay to make a dollar.

"You Get What You Pay For", is a mostly true statement. Sometimes you find a deal and it work great. Sometimes it doesnt.

Just buy one of the cheaper ones and see what happens. You be the test subject, If it works you prove that everyone can save some $$$$. Then most of us will still buy a proven brand. Even if it does cost more.

cheap blow off could leak ,it could not blow off when it should which is why you buy it in the first place for sound but to also protect the turbo. And if they leak you have boost leaks maybe rough idle problems.

Sorry but I buy brand name quality stuff. Thats just me and if you buy knock off wastegate or turbos well best of luck!

I definatly wouldn't use one. Could damage turbo/motor or leak. Plus nice thing with tial(and other big name brands) is they have the different springs and documents all for you

Yes they work off vaccuum but tial reccomends different springs for motors that make different amounts of vac. This is one of those times, when saving a little bit, could cost you alot more. But buying a good product you know you wont be let down.

im not arguing, just have yet to see a justifiable answer. If the BOV fails...you'll obviously not hear it and know to fix/replace it.
As in leaking...for a valve 15, 20, even 40psi is not a lot. I was a pipe fitter for quite some time.. usually the difference in prices when it comes to any kind of valve was the material its made out of or the pressure it can handle.

Im just wondering if everyone is sheep.....following the general path because "everyone else is" or they have their own reasons.

wastegates definately not.. I tried that path to save some money and it ended up costing me money, thank goodness nothing was damaged besides the wastegate from the incident but it could have been bad.

I bought one of the older Tial style knock-offs when they first came out and that BOV went from my vette and worked flawlessly at 20psi to my DSM and held just fine and never missed a lick at 40psi.

however the reason it went on the vette is because I bought an Xo2 50mm blue BOV and it was crap. the tial knockoff was actually VERY well built.. it was an exact replica of the real deal.. they discontinued them, I am guessing for copying and getting in trouble.

I still look at fleabay stuff from time to time. I am running an intercooler from ebay on the vette now and ran one on my DSM also at 40psi and 635awhp, again never missed a lick!

it is hit or miss.. do you research on the brand your buying before you pull the trigger.. buying 2 or even three times to get a good cheap part isn't cost effective and the aggrevation that goes with it makes spending the extra dough on the real McCoy seem worthwhile in my eyes.

Lots of solid companies advertise on ebay. Have bought tons of parts off it. But as said the knock off crap is out there too.

Its all cool man, meant no offense. I have spent the last 7 years fixing industrial equipment. Every thing from small & large pneumatic & hydraulic systems, cheap *** hydraulic valves and flow controls, to quarter million dollar robots big enough to toss a car across a parking lot.

On top of al that I have been around the Turbo block about a million times. I go with what I know works. Cheap parts lead to failures that can possibly kill a engine. I wont split hairs about an extra $200 bucks for a quality BOV when it come to my personal setups or those that leave my shop.

Cheap parts can work. We all know that. I wouldn’t say we are sheep following the path. I would say we are the Wolves that that eat the sheep following the path to EBay's one off, knock off BOV's, and WG's.

Its all in good fun bro.

If you want a cheap BOV that honestly works good look for a 1G DSM BOV. Metal hold around 18 pounds in stock form, you can "crush" them(easy to do) and they'll hold 22-23 pounds all day. They'll run you about 30-40 bucks.

Ive personally seen cheaper units bleed off extra boost which causes a tuning nightmare. Also units fail, turbos surge, turbos fail, send pieces of metal through your motor = done.

Buy a Turbosmart from a supporting vendor, dont think twice.
