Sabre IIB or not IIB on 150 fuel
I allways thought for the Sabre II engine to run at 11lb boost,it needed 150 fuel but then I came across this http://http://i.imgur.com/lUhGjmD.jpgwhich has the Sabre IIB runing at 11lb boost ,but just on 100/130 grade fuel,what going on here? is this right? or is this some post war thing,as so...
