A mechanic told me that you can lose a lot of hp if you line the engine straight toward the final drive if the engine/gear is not installed dead.
The installation can also steal a lot of torque if not lined correct. And it’s also more prone to get vibrations.
So my question is how should the engine/gear be lined up against the final drive when you use rubber bushings for mounts?
Is it different if the car is used on street, track or drag also?
Maybe someone even have a document describing it in a good way?
I have only found
this.
