Autokonexion test fits. Clay Deen at deCaudellas is going to paint them and put them on. Hardware will be black to blend in. Not chrome or silver.

Yes, I'd say the vast majority of us have used it in the past. Every organization ive ever done a track event with has said "no ethylene glycol based anti-freeze in your coolant system" so we end up running distilled water + an additive like "Water Wetter" or Royal Purple's "Purple Ice"

I was wondering how it would affect the turbo itself. I'll look at purple ice now that you've brought it up.

Their site says that for street driven cars to not run a water + additive only. They suggest a antifreeze and a single bottle of purple rain. So I can just add a bottle to my reservoir and call it a day?

Hey, just last night I started hearing a whining noise under load and acceleration. It goes away while coasting or cruising but one I touch the pedal it comes right back. It gets higher pitch as the speed increases.

I got under the car and looked at the axles, shaft, and diff. The axles look fine along with the diff. No leaks. I can turn the axles by hand myself and turn the wheels fine. There is a small tranny leak but nothing alarming.

I only use water wetter in cooling system that i use no antifreeze in. Otherwise.... MEH.

That's normal noise from the diff after a proper poly diff mount bushing install.

But I didn't hear it before until last night. Some research and suggestions were axles, diff, shaft, tranny, wheel bearing. I highly doubt it's the axles, shaft, and wheel bearing. I just put in fresh fluid in the diff and it seems fine to me. I would say it's the tranny.

Well, if you have a 6 speed sitting there, i'd do that first and go from there. 6 speed is tits anyways.

I have one with my name on it from a 04 msm with 110k miles.
But it's not ready to be sold just yet and installed. If the transmission is the cause then I just might be able to get it installed that much faster by the seller. I just hope it's not the differential because I just fixed the axle and mounts.

Any other diagnoses I can perform while the car is up on jacks? Perhaps burnouts lol

What manufacturers say to do and what we end up doing around here are generally two completely different things. :giggle:

I've been running distilled + Wetter + trace amounts of antifreeze (becausecalifornia) for a couple years now with no issue. If you are really worried about it, run the antifreeze in the proper ratios, add a bottle of whatever poison is your pleasure, and roll. Neither of those additives are going to hurt a turbo.

It's speed related with the acceleration pedal being pressed.

It's super loud near the parcel shelf

Under load acceleration:
you can hear it good over the parcel shelf.

I had something similar happen. I thought it was the diff so I replaced the vsld with a torsen turned out my driveshaft bolts were a tad loose not diff related at all.
hope you figure it out :)

I checked the bolts and they are tight. At least I can't make a difference tightening or loosening with my fingers.

How loose where your drive shaft bolts?

How I wanted to type this:

The nuts on the shaft are tight. How loose were your nuts? Lol

The diff is on its way out. Gonna now install a 3.9 with a six speed this weekend.

I approve of this thread.

Thanks urbansoot. This is your sale put to work.

Which company sells the best heat wrap to wrap my dp, radiator hoses, and power steering hoses? I also was thinking of cutting a hole and running air for the cowl to the back of the engine to reduce temps and or cut a hole in my hood.
I was contemplating a chaser aero hood but I don't want a carbon fiber hood.

Reason is that when I turn my ac on the engine temps crawl up past 220 degrees and up unless I turn it off.

In one of your earlier videos, i see there was no undertray. Have you fixed this? Because no undertray = overheating.

There isn't because of clearance issues with the piping. Did anyone run into similar issues? And so could they show a picture of their under carriage

Trim the tray if you have to. But not having a tray will really mess up air flow through your radiator.
