Does anyone here have real world knowledge of tuning engines at 11,000 to 12,000 feet? I have a customer in South Africa that seems to be having some trouble with a 572 hemi. Most of the advise that works here does not seem to be working there.

Some high altitude world war two planes ran the bottle.

Can you provide an example?

The Germans used NOS on the Messershmidt ME109 and possibly other WW2 fighters to get high enough to go after our bombers at the beginning of the war. I read this in a book about WW2 According to that book the motors had to be changed out and overhauled after each mission, the jets and rocket planes ended up being the answer(a fine example of to little to late, thank God) to our high altitude B17 G models with superchargers and coumpound turbocharger on them

Actually I should not have used the word boil. With the 9.5 converter the car's water temp is 220 and climbing whereas with the wuss 12inch it runs 185.

You guys did give a thought though. Would it not make sense that he would need a higher pressure radiator cap at that altitude? I realize the water actually boils at a lower temp but the production of steam bubbles cannot be a good thing.
Thoughts...

From rereading/interpreting your posts , your basicaly having a boiling problem of the cooling system. Not a Boiling problem of the tranny fluid.

Its the Trannys two different verts stall differences that are effecting and contributing to this extra heat to the rad.

With the extra altitude, 12000 ft. yes you will want a Higher PSI rad cap to counter the effects of the lower pressure atmospheric conditions, at the higher elavation. mike

Well , i'm not really into world war two planes so don't know anyting about them , what i do know is nitrous oxide was first used in german fighter planes , some british planes also used nitrous oxide , don't think you guys (US) caught the bug ............one aircraft that used it was the TA-152 , i think the system used was a 'GM-1' , the pilots could fly @ a higher altitude when 'on the bottle' , was also used for increased acceleration.

The pilots better hope they had a good 'tuner' back then , having Squeeze around in those days would of put those pilots mind @ rest.

only messin around Squeeze , could'nt help myself.
