So I've just about finished my turbo dual cab 1965 bus.
It's a 2276 EFI turbo engine pulling 267hp at the fly. A few teething problems but I'm just about there.
Cooling wise it has an external oil cooler and and water/air cooler for the turbo.
The daily temp here in Australia is heigh and I'm having a few small running issues so I have a few questions:
I've read that people have been cutting holes behind their number plates to try and get more air flow. I've done a few searches but can't find much info on this, does it work? I'd also though about putting vents in the engine hatch, would this be a good idea?
What about vents above the engine in the tray of the bus?
I want to stay away from scoops!
Have people put in dual external oil coolers?
It's a massive motor in a small space so I think I need to let more air in.
Sorry for the quality of the photo.
