bike engine prop tunnel
hi iam gonna fit a bike engine in my locost but does the prop run in a straight line. because i was thinking of making the tunnel smaller to the same
size as the back bit. so i could have more room for my feet.

Leave the tunnel till you have positioned the engine ?
It will still be tight in the footwell on the drivers side as the output from the bike gearbox when placed in a car tends to be well over towards the
drivers side.
You will be able to make the tunnel lower and probably narrower but to the benefit of the passenger rather than the driver.
You may want to consider moving the engine back a little to ? I stole 6 inch's from the passenger footwell to move the engine back in the
chassis.

Exactly as Jon says.

This one? 
 
R1 Prop angle
This is a book chassis with an R1 engine which gives a straighter prop than most due to the stacked gearbox on the R1 which makes it a very narrow
engine.
When I had the blade installed in the same car, the front corner of the engine head was virtually touching the chassis above the frontmost exhaust
port, and the prop was further over towards the driver almost touching the footwell tube.
If you put the engine in at an angle so the head follows the line of the chassis rail you can get the output shaft more central, but there can be
disadvantages in doing it that way due to prop phasing etc leading to prop vibration.
