Yellow. I think it is the 20-25lb spring.

She begged me to take her out for some sunshine and cool dense air. Conditions were right, so I shot a couple shaky phone vid. Audio is decent if your not watching them on your phone.

One 2rd through 4th:

And another in 5th gear, floored, from 1500rpm/30mph to about 5000rpm:

thast AWSOME!!!. glad to see some videos!!!!

nice! pulls pretty well. Though shouldn't lug it like that. Your poor little turbo will go pop. Though i'm sure you already know that.

I know its bad to lug any motor but was unaware there were additional adverse affects on the turbo. I've had a couple stock turbos but would consider myself a novice. What is it that it's doing? Bearing pressure? EGTs? Lower oil pressure? Skool me!

Surge. You can hear it in the video.

Hm, I don't know if I'm hearing surge or the BOV fluttering? What turbo are your running, K03? K03s?

Tis the ko3s.

It's the low rpm surge with high load. Turbo makes more air than the engine can take.
