You'll gain boost response with a bigger intake pipe. Basically a bigger pipe acts as a reservoir so it can pull more air in a surge without having to accelerate airflow along the entire pipe. See if you can match diameter with that air-filter outlet.
Understood and I’ll make that happen.
May I ask what your opinion is of what I have set up on the other side of the air filter intake?
It’s an ARB snorkel for 80 series Land Cruiser, modified to fit my needs. Put there to provide fresh air to the motor, no intention of deep water fording or mudding. If the snorkel isn’t more of restriction than benefit, I’d eventually like to swap out the scoop for a Donaldson pre filter top.
And Mr. Dougal, thank you for being so generous with your time and knowledge to this and other forums. Turbo choice and installation, thread pitch for water inlet and oil sensor, are a few items that you’ve inadvertently helped me with during this particular project by reading past threads. That’s not counting help with the other rebuild as well.
If you ever come over this way, I’d like to buy you food and drink in a non romantic fashion.
