What will happen to boost going from 1000 to 10,000 ft?

[flatlandsledder]

This question is regarding a Aero 53. Lets say I had 10 psi here in Iowa 1000 ft. Would the turbo have more or less psi as I go up in altitude? I'm just trying to learn the ropes of the turbo world. Just wanna be like you guys. Thanks

on the Mcx turbo I had they had an aoutomatic boost adjuster as the boost will go down as you go up. When mine did not work I lost about 4 lbs from 1400 up to 6000' 02

it will not make the same level of boost, you will lose a few # going up that much

not sure what its on, but i wouldnt recomend trying to pull 10# out of a 53 at 10k feet on anything bigger then a 600.. just a thought.

General rule of thumb is, you will loose 1 point of atmospheric pressure for every 2000 feet you go up in elevation. At 10,000 feet you are loosing roughly 5psi as compared to sea level.

sled ran like crap(fuel settings at 6000ft) and i lost 2.5-3 lbs from 1000 going to 6000. when i turned up boost it ran better and only had to move about one number on the fuel box.

lose psi

On my m8 w/6push turbo I run 8 psi at 1000ft. Then when I go west and run at 8000ft I lose about 3 psi. I just turn it back up to 8 psi and my fueling in real close again. I also love not having to change my clutching anymore!
