Maybe he was using the word "congress" loosely?
As in, It takes an act of congress to get anything done around here.
Rolls Royce cares a LOT about the Allison ort they would not try so hard to kill it, even today.
The reall cuplrit behind the tractor association rules may be simple Europen pride, and not Rolls Royce, and that is understandable given that the series is run in Europe. In any case, they tried very hard to kill the Allison in tractor pulls. Only the fact that Joe Yancey cared enough to make up new cylinder liners and pistons allowed it to continue. He probably cared because he has European customers running his engines.
If Rolls Royce doesn't care, why can't you get information about Allisons from them?
Why have they filed for almost every web address with "Allison" in it?
We have to deal with Rolls Royce interference on a daily basis since we build Allisons for a living.
There was and still is a design change approval process for designs where the US government holds manufacturing or export rights with regards to military equipment. Things like radios, engines, turbochargers and some other accessories were supplied by the government to airframe manufacturers and was referred to as "Government Furnished Equipment" or GFE. Just because GFE was controlled by the government, there were "engineering change orders" and contract modifications to make changes to designs that were controlled by the government. One had to justify a reason for such changes and it ran through a review process that involved engineering, quialty assurance and manufacturing representatives from both the contract and government. I actually served on one of these boards when I worked for Lockheed and worked with folks who did this function during WW2.
A question about the XP-40Q-3, If I may.
I've read at the Vee's for victory that it's V-1710-121 was able to deliver 1700 bhp up to 26,000 ft. That was WER, with water/methanol injection. Was that engine featured an intercooler/aftercooler?
