Noise levels
Can anyone tell me how the noise levels are measured for vehicles with multiple engines?

I don't think there is a noise level restriction for multi engined cars due to it illegal to have more then one powering engine on a road car.
Hope this helps,
Andy

Are you sure? Tiger makes the Z100 which is dual engined, and as far as I know, road legal:

Sorry, i've made a mistake, your right! The rule is that you can't have seperate engines driving the front and rear wheels seperatly! But
you can have two driving one end!
My mistake!!

What about tiger z100wr?
One engine drives front wheels and one the rear. They are only linked by electronics.

..........or Chris Allanson's new twin Hayabusa turbo Ultima 4wd, one drives the front and one the back on that.
I have never seen a rule outlawing anything like this.
Personally really don't like the idea but I'm sure there's nothing to stop you doing it!

dubsport have built Golfs with two VR6 engines - front and back to give 4wd. Linked by throttle and gear linkage. It must be legal. Im sure they were
able to turn one off and revert to single engine if there was a problem as well.

just exercising the grey matter and thought, just make sure you exit the exhausts on opposite sides of the vehicle, then noise will be less of an
issue, and it must be ok to do this as this is done with v8's etc!!

they then get the middle
median??
one side 35 other 37 then the noise = 35+37/2 = 36 DBa..
same with emisions..
