it’s zero at all altitudes...LOL

I thought it was 18.7 psi boost at 8000, so it should be 24kpa at 6500 feet no?
Well I thought so too but when accounting for the coriolis effect and parallax, it comes out closer to 6.9 hectobars per fortnight. But that's gauge pressure, so be careful with going to the bank with that eh?

so a silber at 4lbs is actually at 8lbs if your comparing it to a 850T lol? must be very poorly designed then
what's atmospheric pressure at 8000 feet? lmfao
so the turbo does produce boost then. glad we settled that...

Shiet disturbing 101 eh Dan. Love it!
I do beleive no matter what, it produces more power than yours. Bwhaaa.
Get a sled. We need to go riding again....

If i reverse the hose on my vacuum cleaner I end up with pressure... ha
I can plug into my quad and get boost...

Atmospheric pressure at 8000ft @ -5C is 10.67psi - the stock turbo will push 4lbs of boost - to maintain the 14.7 in the manifold @ 165hp - but if the manifold pressure is 14.7 and you have a boost gauge coming off of the throttle body - it will register zero boost - because a boost gauge will only register pressure above 14.7 - I don't think I can explain it any better - it's quite simpleI thought it was 18.7 psi boost at 8000, so it should be 24kpa at 6500 feet no?

All the guy did was show you with a hand pump the loss of pressure due to altitude on a gauge - the reason why there is a big square box at zero is because they don't know where the consumer is goin to live - sea level - or 2000ft - or maybe colorado

What if I run regular fuel? I heard it will boost more higher. 6 hectobars the one guy claimed. Not sure if that was guage or absolute though

A more important question fellas, how much boost does the 850T make at idle?
