Boost and elevation changes

[yammi4ever]

Just wondering how much tinkering there is when going from sea level to elevation. If I turbo, I will spend 2/3 of my time at sea level and 1/3 at 8 to 10000 feet. I plan on running 2 different boost levels, lower at sea level and higher in the mountains and I am assuming that that will take two different maps, but what about the elevation. Will I have to fiddle with this to make it run right. I want to keep my turn-key reliability, and do not want to be constantly tweaking. This will be a pump gas (91-92 octane) turbo system. Still not sure which one, but leaning towards the Powderlites right now if that matters.


I realize that the clutching will have to change, but I am used to this.

Any comments would be appreciated.

Low comp pistons or head shim? fuel injected? You won't be running much boost at sea level on 91-92. If your using fi, you should be able to map pretty easy for elevation. An RB3 box or Pure logic box would be a good idea.

Sorry, should have given more details. Yes a head shim and would be on a FX Nytro so fuel injected. Powderlites is using a RB3 box. Planning on 8# at sea level and 10 to 12 at elevation, depending on the fuel available.

Thanks,

The MCX kit has a TCV to adjust boost to elevation so that you would not have to do this. Their EFI box should take care of the fuel mapping also.
