Drive shaft angle with engine swap.
Discussion
Currently fitting a Honda k series engine and AWD drivetrain to a 1998 Subaru justy (the one that is basically a Suzuki swift but AWD). We don’t have much wiggle room up and down with the engine, or side to side, or even to lean the engine forwards or backwards due to the drive for the prop shaft coming out parallel with the road surface. What we do have is a couple of inches to move the engine forwards or backwards if need be. The engine seems to be in a good spot at the moment to fit with manifolds etc on......but I’d rather have to lose my brake servo or have an inlet manifold, or exhaust manifold fabricated if it means the front shafts are at a “good” angle and not chewing through CV joints or breaking shafts every time I use it. From google searching I’ve found out and learnt a lot about prop shaft angles but can find nothing about drive shaft angles. At the moment the hubs are a couple of inches towards the rear of the car compared to where the Inner CV joints go into the box, and a couple of inches lower. This seems to be roughly similar to other cars I’ve looked at, although maybe the shafts don’t usually sweep as far back. But with the wide distance between inner cv’s and the narrow track of the car, the shafts will be pretty short so any angles harsher than if the car was wider. Any input on this subject much appreciated. And any links to articles or videos covering the subject also a big help. Thanks in advance
As an example in a recent project I worked on: It was recommended by the joint manufacturer to try to acheive a constant running angle of less than 6°. The joints were high-capacity BMW CV-type 8 ball drive joints. We were concerned about going much over 11° in dynamic situations.
If you have tripod-type joints you can safely take higher angles.
