Anyone ever heard of a TiAl wastegate spring wearing out? A few years ago, boost was dead nuts at 10 psi. Now it's dead nuts at 12-13 psi, and when the wastegate is open I hear a "pulsing" sound. This happens with the boost controller completely disconnected. Seems to me like the spring is bad. Lord knows it's been used a lot :D

Never heard of a TiAl going bad, but it sounds like perhaps the diaphram is starting to leak.

Mike Maybe you have a leak in the WG hoses as well.

I'll have to agree with that possibility, When someone reattatched my WG line after swapping in the motor, they failed to slip the thermo sleeve under the clamp, well needless to say when the wg opened up ( I dump to the atmosphere) IF burnt a hole about the size of a bic pen in my wg line. On full throttle I was boosting 15 lbs on up when it should have been at 10lbs, Lukily I figured out that was the problem rather quickly and saved my motor a head ache.

It's official. Deltagates are crap! Everyone always told me to junk it, but I never had a problem until now! Mine quit regulating at 5 psi and now goes to 12psi, good thing I had the fuel to support it, my high boost setting is 12psi. Tial 35mm here I come!

I dont understand why some individuals can't make up their mind between getting a Deltagate or a Tial, The tial 35mm go's for 220 dollars from Road Race Engineering, compared to the deltagates what? 175 180 something, It's not that hard of a decision. Don't be cheap when it comes to stuff like that, it will turn around and bite you in the ass later.

I couldn't agree more.. Take the Deltagate apart and you'll see why.
