I can finally join the modshack club after today's install. I had to get the older model TT coolant temp sensor, not the green one, at the stealership for $42!! Is this price correct, because the green one's are only 5 bucks. In any case, I figured with the rough idling, I should replace it before doing any mods. With the temp sensor replaced from a blue squared connector one to a black connector temp sensor, I was ready to start modding. After I finished the installation. I took her for a test drive. As I stepped on and released the gas, a whistling noise could be heard. I kind-of pinpointed where the noise might be coming from. It was around the N75, where I just hooked up the boost machine. It sounds like a leak of air from one of the connections, but me and a buddy double checked them and they all look good. The leaking air sound is killing me. Help? Any tips?


Step one, gather up all the goodies.

Just more noise you're hearing from the DV and intake. How's it running and what are the boost mumber?

I don't have any numbers yet. But the noise doesn't sound like a consistant "shhhh." The pitch gets really high while driving like air coming out of a balloon. Almost sounds like squeeling, I wish I could record the sound. I'm going to try to record the sound, but it probably won't turn out. Should I start playing with the boost machine a bit w/o the guage and maybe the noise will change?

Failing DV perhaps?

I doubt it, a Hyperboost DV? I'm going to clean and regrease it soon.

I had a Bailey die, why can't a Hyperboost?!

more turbo noise "out" than the stock box. This is not a problem, just a difference between the two.

Noise comes from around N75.
