Boost PSI vs. Altitude-The Mile High Club

[04-MystiChrome]

Up here at 5,300 feet with a 2.93 my boost runs about
11 from 2500 to 5500 rpm then fads to around 10 at
5500 rpm then finally 9 at 6,500 rpm. For you other mile
high guys how is your boost running? Man, do I miss all
that extra power down by the ocean.

I see about 14.5 and it drops and holds at 12. This is on a 18-19lb combo at sea level... Sucks Donut.

Yep-Times at the track sure suffer as well bigtime.

Once the snow melts... I will fire the snake up and find out how she does at 7500ft. I can't wait to cruise through the caynon roads though.:beer:

I have a "6lb" lower and a 3.2" upper. I think that's about a 15 to 17 psi combo down low. Up here that nets me 13.5 peak or so, dropping to 10 by redline.
