I have been looking to the pics of that bulkhead plate and the only reason to use this is too mount some electronics and a swirl pod on it.
I just don't get it why the engine is completely protected from cool airflow exept from cool dirt underneath the engine?
Is it for fire prevention in case of an accident?
The bulkhead plate isn't for torsional strenght right?
And it does look ugly from the rear view.
thx in advance,
Erik

I can imagine the exhaust heat will warm up the seats. But other than that I don't know why you can't leave it away.
But, in my opnion, I think it looks better when it is mounted... But that is personal of course.
I don't know whether the regulations demand a bulk head. For closed bodies it is mandatory, but this is an open vehicle, so maybe the rules differ...

I was thinking a perforated bulkhead might be a better choice as well. More options for experimentating on the electronics as well. I just don't get it why the engine doen't have direct airflow in between the seats...
On open cars a screen is placed behind the headrests for less turbulence on the heads location. I was thinking to close this area as well with a perforated screen or even radiator(s). This might affect top end speed tough LOL!!
If I don't use the provided alu plate for bulkhead I could use this to enclose the bottom underneath the tanks and enging to keep the rear clear from street dirt. I don't ecpect much cooling from there.
Adding a hole in the middle from the bulkhead may help cooling the exhaust pipes. The heat radiation will heat up the coolant. at this moment i am not sure if I want a closed bulkhead or a radiator in front of the engine and I don't understand why the radiator is moved to the front of the car in a FOD area. The additional costs of tubing and clean up in the tunnel are worth being noticed. Because I may plan to use the bike clip on switch (left side only) and a handbrake on the left side of the seat I could lead the loom to the left side of the car as well, discarting the tunnel and create room for a lunchbox (unless one can show me an other location for some refreshments)
Show me your thoughts!

When installed on a motorbike the engine is behind the radiator. In the tR1ke the engine is behind the bulk head.
Because air is forced around the car very likely there is a under pressure behind the bulkhead. Perhaps there is a way to use this under pressure for extra ventilation.
Keep in mind the aluminium cooling pipes going to the front radiator and back also offer extra cooling capacity.
I also do not like it when all electronics, swirl pots, expansion bottles are mounted to the bulk head. Therefore my bulk head is empty.

Euhm, a vacuum doesn't create turbulence. I think there will be very poor cooling in between the tanks. All the exhaust pipe heat will be radiated to the engine and tanks and heaten up the coolant even more. On the R1 there are cooling slots under the radiator for the exhaust pipes. On the R1 the radiator is in front of the head and airbox. Keep in mind the radiator doesn't block the airflow completely unlike the bulkhead in this design.
I wouldn't be suprised if the engine will get too hot too easely.
A clean bulkhead is nice but if all hardware can be fitted in a box then I think that's okay. That doesn't mean the box needs to be on the bulkhead...
