I don't know the details of why the P-63 project did not work out. However, I doubt if it was a carb problem, remeber the same carb was installed on the P-38 operating under positive pressure conditio ...

Bill Kerchenfout tried a pair of turbos on a P-63 many years ago. According to Bill it didn't work. We'll get all the nitty gritty details at the convention where Bill will divulge all his "secre ...

John - this is wonderful news..!! Will you still be the flight engineer when FiFi gets airborne again? Also, what engines; -57s or -26WDs?

Forgive my ignorance but is the Douglas you refer to the Douglas motor cycle company? As I am sure you are already aware of, Weir is mentioned fairly extensively in the Wolsely book. Most people think ...

Although the Crecy had great potential, insurmountable problems stymied its development. After R-R wisely threw in the towel to concentrate on gas turbines, Ricardo soldiered on but to no avail. Accor ...

I read the 3500hp claim as well. I would take it with a grain of salt. As you know, the ‘45/’46 AWA is full of errors and this is not surprising considering the sheer volume of information availab ...

Air cooling was the way to go for commercial applications. If you look at the QEC for, say, a Northstar it’s amazing that this complex system was kept maintained. For military applications where cos ...

You may want to contact the Napier Power Heritage. The new book by Alan Vessey quotes the highest rating for a production Sabre as 3,050hp for a VIIA. However this is the power rating for its type tes ...
