Engine decluttering

Here is my engine as it is right now:

"Scoundrel", not Outlaw...



Its out and I am rebuilding it and the car is in the paint shop having the engine bay resprayed in the outside colour.

As you can see, its quite cluttered in there, so am looking for real-world advice on how to de-clutter the engine without harming performance.

I have seen people cutting down their airboxes, drilling holes in or replacing them with cone filters. How much of a bad/good idea is this?

Secondly, there is too much pipework criss-crossing the engine: How do I get rid of that, or re-route it in a way that I don't have miles of piping everywhere?

Finally, how do I tidy the wiring up so that it looks more ordered?

I have my own ideas, but having worked in isolation on this car for years now, not all of my ideas are good.

Search for heater backdate, that gets rid of the hoses to and from the blower and the blower- you hook them right to the side of the fan with a couple of different pieces of tin. Very easy and not too expensive.

If you want the ultimate in clean good looking engine bay, ITB/EFI is the way to go; very slimming for you too as your wallet will get extremely flat afterwards!

No AC and heat backdate on my SC with CIS. I can get to everything (except items behind airbox quite easily.

I think I need the tinware first. My engine is out right now and I'm rebuilding it, and the A/C was removed a couple of years ago.

Do you know where I can get the tinware and will ship to the UK?

I assume you’re speaking of the air ducts coming off the fan shroud. Bought mine on Pelican. My car is an ‘82SC.

In the medium term I'm planning to remove the heat exchangers and do without heating. In order to declutter now I'm thinking of removing the blower and routing the air from behind the turbine to the left heat exchanger and put a plug on the input to the right heat exchanger. Is it a bad idea? There will be no flow at all on the right heat exchanger.

I did a basic backdate with simple tools and $100 in parts. If you buy a custom plate for the driver's side, it will cost more but you'll eliminate the hose twirl.

You need to keep the air flow if you have heat exchangers. Engine builders I've spoken to think there is a risk of overheating the valve guides otherwise.

Thanks for your input. This is exactly what worries me.

When the heater valves are closed, there shouldn't be any air flow through the heat exchangers, otherwise heat would come into the cabin even in hot weather? (Unless the heater valve is actually a diverter) This suggests airflow through exchangers is not needed except to channel heat into cabin.
I could be wrong.
Good luck,
Dave

Heater valves are diverters. It vents the heat under the car.

Type911.co.uk can provide the parts needed for the heater back date. Ditch the blower.

I have no doubt you are right. How does it work?
