Hi
so, the connections are already sufficient, BUT with a turbocharger already at 1.5 bar boost + chip + water/methanol injection...
'I've had a lot of problems, such as imperfections on the aluminum parts and cracks in the hose, etc.'
Probably also because it's a renovation. These are just minor disagreements.
I have a slightly modified air intake system that produces 1.7 bar of pressure. I suspect it is generally too weakly defined.
My father has an Octavia, it's the 110PS version + a chip. Has operated flawlessly for 120,000 tkm!
So, the basic principle of the connections is definitely fine.
Regarding adapters, I've already been there. They are not available individually.
I will have the adapters made. I'll contact a local company and see what they say.
Best regards, Marv
