LBZ: Big single, higher altitude problems
- Thread starter Cknight199
- Start date
Working on dialing in some rail pressure bounce. Logged it this morning and got the logs to my tuner. Thinking of stepping up to an s483 since I can spool now

S480 will be in tomorrow night. Throwing in the drive pressure gauge tonight to see if I should run a .9 or 1.0 housing (currently have a .9 with the 76sxe)

Excuse me if I missed it but what S480 setup did you go with. I am considering ditching my old school S475 for a new S482SXE turbo and would like to stay up to date on your runs.
Can you get one with a t4? I was checking out some turbos and didn't see if they where.
It's a s480/87 FMW. Going to try a .9 and 1.0 housing and monitor drive pressure. Should have some good data over the next few weeks between track times and dyno. I'm keeping the 76sxe to swap between.
The SXE that are 80+mm above are t6 only from borg. You can get a hybrid built that is swapped to a t4 but it's expensive since you can't get the wheel and cover by itself.
My 76sxe is supposed to outflow the 80mm FMW according to Borg, but idk if that is accurate them at my altitude.

Also bumped my line pressure and modified the flow valve in my trans while it was out.

Very cool can't wait to see the results.
The S482 that I am looking at is suppose to be about the same on the bottom end as my 475 but of course more air up top. I guess we'll see what winter brings as I am working on acquiring another money pit Duramax lol.

Glad to see things are moving in the right direction, was lurking on this thread while you were troubleshooting. Go give it hell at the track :thumb:
New turbo has arrived. Now the question... At this altitude will a 1.0 benefit me or does having higher drive (.90) help...?

See I have tried the 1.0 before and it felt like it wouldn't stay on top. I am going to go with it though since the 80mm should create some more power
