Effect of boost control cutout prior to +12 psi boost modifications

Lol

- The XX was a post BoB product hence as a fighter eng it shld hve beneficed of the former improvements
- If 12lb MS is indicated it EXCLUDE any use of this level of boost above s/c alt

Sry but your statement does not match any engineering rules and is contradicted by the submitted text.

Let me explain : Supercharging put strain on your eng (300HP at recovering s/c alt)
If at low alt a boost level is restricted it certainly can't be achieved at alt !!

To give an exemple, my car has a turbocharger at 1.4 bar of boost (nearly 1.4 atm)

I once had a friendly race against a motorbike in a mountainous road from 1K up to 3K meters. My boost is electronically regulated. My turbo s/c is capable of much higher boost value to be reliable in a series car. The higher we went the better was my engine against the motorbike naturally aspirated engine (same boost same HP for me- Lowering boost for him) up to the point that my 1.4t cars "matched" his much lighter vehicle. BUT the temp went to high as did the strain and (hopefully) the electronic module give it away before I blew the eng.

That's what you risk with super/turbo charging. The lower the outside pressure is, the more the strain on the engine (mechanical or thermal respectively) will be.

If a limit is settled at low alt, it means that it can't be superseeded at high alt otherwise the limit would be put at s/c alt (but as it was difficult to have accurate pressure measurement at alt in a moving ac at the time they might have choose to rely on a low alt limit).

Baaah forget it I know that I am certainly loosing time writing this
