So for the last 3 years (off and on) I have been designing an engine. I have gotten much more serious lately as it could help me get a job that I seriously want, but somethings have stopped me in my tracks. On of the biggest things is the g.d. crankshaft. It is a pain because it does so much for so little... so, so little. Here is the question: is it possible for a v8 crankshaft to be angled to 45°? There are the old/mundane crankshafts that are angled to 180° and they were horrifically unsmooth, and then there is the 90° which is smooth but if it could be smoother that would be nice. The engine is designed to run up to 15000 rpm and put out about 550 hp with n/a and 13000 rpm and about 750 hp (really mild tune) with twin turbos. Now in my mind 45° crank would work but could it get ahead of its self? Could it be too close, possibly causing misfire or under rotational fire? Now what if it is pushing in nearly 3 bar of air? Could that cause problems? Thank you for any and all help.
