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?

 

I have one and it works fine

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

 

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

 

Boost cut makes cdm waste more trust worthy.

 

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...

 

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
