I tested it offline several times........WEP lasts about like Mitsu said, about 70 seconds, but it went from redlined to normal temps in 15-20 seconds, making repeated bursts of WEP possible.
Dang, I wish the Jug engine cooled off that fast.......heck, I wish just about ANY other plane's engine cooled that quickly.
BTW, I never got it to go above 389mph at any alt.
Did level flight top speed runs from 15-23K, in 1000 foot increments, i.e., 15K, then 16K, then 17K, etc.....
The boost guage seems wacky to me. At one alt, I will have to review the films, it was pulling only about 150mm/Hg boost, then I hit WEP and it shot up to 400(!!).
Over 20K or so, no rise in boost with WEP on.
Watching the airspeed indicator, when you hit WEP, it acts like you engaged N2O or a RATO unit....lol!
GAWD........I've gotta get back into the MA and have some fun with you guys.
Hopefully after Christmas, I can get RL issues resolved and fit AH back into my budget.
