Default Engines Physical mounting angle.

1. How come some of you chassis builders mount the engine @ an angle?

2. Does that give better center of gravity?

3. How steep can you tilt an engine?

well, in our particular car. we had stock mounts on it....(we have solid mounts on it now, that we made) then rotated it toward the front to align the axles...(looking down from the top) then we also moved it up about 2.5 inches or so to further align the axles.(looking from the front view) we rotated ours about 5-6 degrees from stock...

questions 2&3 i cant answer.

We are building ours on an angle to accommodate our transmission to be level and axles to align. You also need to use a dry sump oiling system when laying over the block. With the right oiling system, I would think you could operate the engine upside down. Piston driven aircraft engines still work when the plane is upside down.

does this also help hang the weight over the wheels for better 60ft's and traction??? Does this also help with different caster/camber angles for better 60fts???

This is a good topic that ive also wondered myself at times.

the engine placement really has nothing to do with camber/caster

Even as far as axle alignment goes?? i would think it has a little to do with it considering camber/caster changes the angle of the axle ever so slightly.

I think i read somewhere that for better 60fts racers wanted more pos. caster (swapping left and right uppercontrol arms). With a new location of the motor you could tailor to these axle alignment changes for best reliability and performance.

or maybe i just got a whole bunch of things confused.
