kieren1234 Posted October 27, 2009 Share Posted October 27, 2009 Excuse me if this is a silly question that has an obvious answer. When i read on a turbo's specification ".60 A/R turbine housing", what does this mean?? Does it apply to the hotside size of the turbo and is .70 bigger than .60 for instance. Many thanks.

kieren1234 Posted October 27, 2009 Author Share Posted October 27, 2009 Cheers Nic, so say i have a turbo with an a/r of .84, if i buy one with an a/r of .60 the exhaust housing of the turbo will be smaller?? Excuse my stupidity Quote Link to comment Share on other sites More sharing options...
Wez Posted October 27, 2009 Share Posted October 27, 2009 Cheers Nic, so say i have a turbo with an a/r of .84, if i buy one with an a/r of .60 the exhaust housing of the turbo will be smaller?? Is each housing single or dual scroll, ie is it one big single port or two smaller ports? Quote Link to comment Share on other sites More sharing options...
kieren1234 Posted October 28, 2009 Author Share Posted October 28, 2009 Is each housing single or dual scroll, ie is it one big single port or two smaller ports? One big single port. Do you mean is the flange divided or not?? Quote Link to comment Share on other sites More sharing options...
Wez Posted October 28, 2009 Share Posted October 28, 2009 Yes divided/twin scroll housing. My .70a/r is divided. Quote Link to comment Share on other sites More sharing options...
kieren1234 Posted October 28, 2009 Author Share Posted October 28, 2009 Ok thanks mate. So if a .60 a/r is smaller than a .70 a/r, does this still mean that the exhaust housing will be dimentially smaller or not?? Really sorry for the daft questions.
