CDM Wastegates???
 

How reliable are they? I don't want to put one on my car if the risk of it not functioning properly and blowing up my motor is relatively high and I also don't want it to stay open at low boost either

Can I just put a legit spring in them and they will function like the wastegate that they knock off or am I just better off buying the real deal?

Re: CDM Wastegates???
 

If you put one on your car you run more of a risk of blowing your engine due to overboosting than running a name brand, that is obvious. Many people use them though without problems. Swapping out with a "legit" spring won't change anything.

If you can afford it, always buy a name brand over a CDM wastegate, since it's such an important piece of the turbo setup and can blow your motor if it fails.

I have one and it works fine

But I would buy the tial if I wasn't so poor

Re: CDM Wastegates???
 

my cdm works fine.... and if you are geting your ---- tuned, boost cut is a real cool feature that keeps ya from blowing your ---- up.... ;) look in to it :4

Re: CDM Wastegates???
 

Boost cut makes cdm waste more trust worthy.

Re: CDM Wastegates???
 

If you buy a CDM, open it up and check out the diaphram... other than that it's up to the CDM Gods for it not to fail.

i had one and only had one problem with it in 6 months of raping my car.
i was racing an sti on the freeway and after i beat him he wanted to run again. so we lined up and my car sounded like my exhaust broke. it sounded like i was running open downpipe.
i figured who gives a ----, open dp will give me more power. we dropped gear and i didn't build boost. my cdm waste gate was stuck open.
that's the only problem i ever had.
next time i'm gonna get a used name brand one or maybe a new namebrand. depends on my job and cash flow.

I have a cdm xs power 38mm gate on my sled. I haven't had any problems out of it. I bought a backup just incase(I also have a backup set of ycp vitaras). Just think you can buy 5 cdm gates for the cost of one name brand gate, set up boost cut or mount your boost gauge where you can see it...

Re: CDM Wastegates???
 

I put limited milaes on my XS power 38mm befure I spun a bearing but I had no issues either.

Just check it with an air crompresser before you put it on the car. I bought one with a "6psi" spring but when i put a regulator and air to it. it opened at 15 psi. >:( So just check it. Or find a tard with a turbonetics evolution gate and buy it for 40$ like i did ;D

Re: CDM Wastegates???
 

ive ran 3, all worked great. the one i have now was supposed to be a 7psi spring...well, it was closer to 15 :S

running a Tial 11psi spring in it right now, at 20psi daily. 7500 miles and counting :6

just run boostcut on your ROM editor and you should be fine. i have mine set at 22psi just in case

Re: CDM Wastegates???
 

i may be biased, but i used for for a while with no problems. the only reason i have a turbonetics now is cause someone was willing to trade me a mint one for a new type-s knock BOV. it was a super cheap name brand wastegate for me, otherwise i would still be running the CDm one

Re: CDM Wastegates???
 

i've never taken a wastegate apart before :'( Is it difficult to put back together, or is it fairly simplistic in design?
I noticed on EBAY they're actually selling new diaphragms for wastegates.

http://cgi.ebay.com/ebaymotors/OBX-W...spagenameZWD1V

It says it fits OBX and Tial 'gates, and the CDM 1's are knock-offs, but do these diaphragms actualy work in the CDM 'gates?

Re: CDM Wastegates???
 

it's very simple in design.

Re: CDM Wastegates???
 

I have been running one for over a year now. Works just like the day i got it. same with my ebay shitty turbo. Over a year and still works perfectly.

Re: CDM Wastegates???
 

they are all the same. it will work. they arent hard to take apart and put back together, you just have to be careful when you take the last 2 bolts out. the spring in there is pretty stiff. when you take the 2nd to last bolt out you need to hold it together while you take the last one out or it will break the last bolt. then once you get the last bolt out then just slowly open it up with both hands. putting them back together is a lot easier with a big C-clamp

Re: CDM Wastegates???
 

On some gates you can use two long bolts/cap screws to compress and decompress the spring...

Re: CDM Wastegates???
 

thanks for the str8 up answer guys. ;D That's so unlike HMT ???

i now feel like less of a :1

Re: CDM Wastegates???
 

if you can by two cheap ones you should have just bought one good one :1

Re: CDM Wastegates???
 

ran one for a year with no problem :6

Re: CDM Wastegates???
 

watch about pinching the diaphram in the tophat of the wg. it's probably the #1 reason why people toss em out.
