Why are there different wastegate sizes (35mm, 38mm, 44mm)

Just wonderring if it makes a difference on what size you buy. I can get a brand new tial 35 mm for $120 but I also plan on a daily driven 350whp A6

So why does size matter lol

Thanks

 

go ahead and get a 44mm, the bigger it is, the more air it can release quickly to maintain the right boost pressure, if you're boosting too much with too small of an opening, it's gonna spike up every now and then.

 

the 40+mm are fawking bank though

That answers my question though

 

Where are you getting the brand new Tial from? or are you talking about the SSAC which I'm thinking about getting. Looks the same works the same.
