Nevermind-POV

[turbojimmy]

Hose came off the turbo. Duh. That explains alot. Still doesn't explain why I have to adjust the valve all the time, but at least it's not broken.

Original post:

I have the POV that Russ Bland is using. Got it from the nice folks in the UK. Every time the weather changes, I have to adjust it. Today is the last straw.

It's in the teens here in scenic NJ, and I'm driving to work noticing that the POV is making lots of noise today. Check the boost gauge - the frickin thing is venting pretty much all of my boost. I figured that as things got warm under the hood, it would be fine. Nope - after a 40 minute drive it was still doing the same thing.

Why would it behave differently in the cold? Wouldn't the spring actually be stiffer? Is there anything I can do about it? I may just yank it and goof around with the wastegate some more (I installed it because it was over boosting).

TIA,
Jim

I have noticed that my boost seems like it's generated much more easily in cold weather, so it would stand to reason that in cold weather the POV is going to be working overtime and depending on the design, might need readjustment. Colder air is more dense so I'm sure it compresses with different properties than warm air. I am betting the air properties plays a much bigger factor in the POV operation than the temperature of the metal making up the spring.
