oh, and also these twin Rocket V8s with Hilborn

Like a boss.

One pump to fuel them all? Also, how do you start it?

Hilborn system means squirt gas in all required 16 locations, then pray.

Edit: presumably each engine has a fuel pump, because Hilborn systems depend on having a pump with displacement tuned to proper fuel volume at given revs.

It looks like they connect right here.

Which would mean a constant displacement pump tuned to pump exactly the right amount for two engines. A bit cuckoo-bananas if the case.

If you're running two engines you've already gone straight past cuckoo-bananas.

Possibly so far as, dare I say it, Cocoa Puffs: Cuckoo 4.

I wasn't going to say it but I'm glad you did.

I should also note: I'm not sure those engines have any cooling beyond just water jacket capacity. At all. Which would be how the water pump location's freed up for a fuel pump, of course.

My brain is just going "but, but, but carburettors!"

So, the ammount of fuel pumped is dependent on RPM alone? Huh.

Yep, with small correction/throttling with some Hilborn setups based on vacuum or other tweaks, but sometimes not.

It's why Hilborn setups don't idle worth crap, start poorly when cold, and generally only operate right warm and at high revs. The pump also has to be matched to engine displacement and airflow.

We all love some air cooled v8 action. That back engine could be running some accessories but it doesn't look like it.
