I've heard 10 hp per 1,000 ft elevation change. I don't know how accurate that is though.

Torque follows cylinder air mass, air mass follows MAP,
MAP follows BARO to first order. HP is torque @ RPM.

So HP2/HP1=MAP2/MAP1=BARO2/BARO1

it takes about 700 ft of elevation or DA to change track times by 1 tenth. I know that isn't the exact answer your looking for but that is all I got LOL.

I don't know elevation specifically but as far as DA goes this was my experience....

127DA - 13.1 @ 108mph 2.19 60ft
3200DA - 13.4 @ 104mph 2.15 60ft
