So I have been thinking about replacing my inlet hose, between AFM and turbo, for a couple of reasons. First is to allow me to move the AFM a little so the air filter can be in a better position and second to tidy the crank case vent/ catch can set up I have.
As a reminder this is on my UT engine in the back of my X.
Option 1 is a combination of universal silicone hoses with a slowly reducing ID. The AFM is 57mm and the turbo is a 45mm input. I was thinking 51mm in the middle for dump valve and crank case vent hose.
Option 2 is to buy a silicone replacement hose, designed to replace stock and then I can modify that to the shape I want. This would give a neater/simpler solution (also cheaper) but all of the ones I have found seem to jump down from 57mm to 45mm.
An example from ebay
They also are of unknown build quality as they are from China.
Ignoring for a moment the unknown quality and coming from China, is a single larger step down better or worse than 2 gradual steps down in diameter?
While I am doing this I want to minimise the turbulence in the air flow.
Anyone got any thoughts/experience with air intakes into turbos? I appreciate this is not the stock X1/9 type of question but I know there are a lot of you guys with more automotive knowledge and experience and I have.
