Actually the 1% P-36 has WEP added as a supercharger! The engine goes from 900HP to 1200, so there is your answer! The only question is how long you can make it last.
Apparently CFS2 has BLOWERS! 
I am not sure how you control the WEP or if you can have 3 WEP settings, but it is definetaly worth looking into!
You would need to adjust the spreadsheet accordingly, but apparently it could be (has been) done! ;D
