Spit Mk1 Boost?

We're saying the same thing btw, no need to argue.

There is no argument at all. I was trying to help you guys find answers to your questions about these machines.

RR maybe 1-2 months

I don't know as I would have to see the actual timeline. I highly doubt it though.

Changes to aircraft do not generally happen overnight. First the change has to be thoroughly tested because the safety margins are by their very nature very tight in aviation.

Once approved, it can't happen overnight either. The changes have to be disseminated to the folks who will implement them. They need the knowledge to enact the change.

Just as important, the people making those changes need the resources to enact it. That means the manufacturer has to retool or reset the production lines, train employees, and get the new parts made. Making enough for the aircraft in service is just the tip of the iceberg too. You have to have enough replacement parts sitting on the shelves to keep the airplanes in service flying. The standard rule of thumb is one part on the airplane, three replacements on the shelf.

So if you have 25 airplanes, you need 100 parts in total.

Of course once the part is made, it still has to reach the flight line too.

In short, it has to be approved, disseminated, manufactured, and distributed before anyone picks up a screw driver to loosen up the first screw to make the change. On average, that process took ~6months in WWII for most designs. The more technical the change, the longer and vice versa.

Just because a memo says it was approved does not mean it was in operational use from that day forward.

Maybe the +16 lbs were allowed for Sea Hurricane IA that operated from CAM ships (catapult armed merchantman) without the possibility to land - engine life is not a problem in this case.

Since Sea Hurricanes were in service in Feb 1941, then the +16lb boost Merlins were available in 1940 since it took, according to you, ~6 months.
