I have been considering a move to a 580 cu in 572-13 motor with 15/1 compression on methanol. Expected power would be over 1050 hp at 7400 rpm. Torque will be 800 + somewhere. Can stock input and output shafts handle this kind of power? Launch will be about 4800 rpm or less, with a converter that will flash to 6300 behind this beast. Tires are 10.5 x 33 hoosiers so shock from launch shouldn't be too bad. Tell me your experiences of stock shaft failures so i can figure out whether i want to try this.
I can say, I have never pushed one that hard....We have made 850hp and had no issues....We build them per what A&A recommends for parts for that level. At your level, a glide will probably be cheaper and hold up better. The only thing is with a glide, it tends to take a couple tries to get the convertor where you want it. Much fussier without that extra gear to get you moving. ...
Now I have a friend pushing a 727 to 1200hp in a blown application, and it can be done, but he seems to find the limits of everything, and that is where he cracked a case....I don't think there was anything else that failed on him.
