As an example
I wil use the spit 5 because its bost was changed for AH. But this could apply to all planes. I am just offerring these numbers as an example.
Spit V now has 18+lb boost for 5 min
9+lb for max climbing. I have seen 2 limits 30 min and 1 hr. I will let the experts determin which is right.
7+lb Max continous
Wouldn't it better if
110% = 18lb 5 min
107% = 12lb 5 min
103% = 9lb 30 min or 1 hour (again I will defer to the experts)
100% = 7lb continous
Get rid of the "wep" button except on planes that had systems like adi, mw50, C3 injection etc....
Running the eng above the limit would eventually leads to overheating. I don't mean that running at 18lbs for 5 min 30 sec your eng should immediatly get damaged but the longer you run over the limit the engine temperature raises until a point where damage occurs unless you back off. I would prefer it to be some variation in the time limits before damage occurs but with "random" anything the whines will be to much.
For the 109E-4 (actually DB601A @ SL; but the numbers are just used as an example and of course will vary with whatever source HT uses.)
110% = 1.40ata 1 min
107% = 1.30ata 5 min
103% = 1.23ata 30 min
100% = 1.15ata continous
Of course we won't have percentage settings visible but we will have to watch mp and temp guage.
