Question about turbo vac tubing
Alright so I just picked up an s5 turbo for my eventual turbo'd n/a project and had a question about the tubing for the wastegate and BOV. The stuff that was on there clearly looked stock and old, so I wanted to replace it with some silicone tubing. Now I was trying to use the stuff I already had left over from before so I wouldn't have to buy any and had a question. The tubing I have is technically not the right size, it's too small. I am able to get it on with a little persuasion, however, and was wondering if it mattered at all that it was technically smaller than should be on there? What I mean is, will everything still work properly with smaller tubing or should I just cop out and buy some more that is the correct size? Does anyone also know what the correct size IS for these? I have some other silicone tubing that happens to be too big and slips off way too easily, so I didn't want to use that.
Thanks for any input.

Yah I've already gotten it on, not that easy
Just wanted to make sure it'd still work properly.

OK dDub. What you need to do is calculate the conductance of the tubing being proposed. This is how much cfm or volumn that is able to move through the tubing. The amount of vacuum being generated by your intake unit also comes into the calculation as well. The lower the vacuum the less the conductance will be effected. Your intake will generate a certain amount of vacuum measured by the lamen in inches of mercury. I prefer to use torr as a measurement of atmosphears. A Piezo vacuum transducer module with a 0.1-999 torr range would be sufficient. A thermocouple vacuum guage would be nice as well. A unit of measure from 10E-2 would also be sufficient.
To be serious The minor conductance differences between the two inside diameters of the tubing will make no difference in the world of vacuum.
