Chad Posted April 26, 2012 Report Share Posted April 26, 2012 a large t3 is smaller inside than a small t4. the r in a/r is ratio, the numbers don't cross over between different type housings. the t3 .63 a/r is smaller inside than the t4 .58 a/r turbine housing, by a lot really.

Precisely the reason I did not go for the t3/t4. i knew the car had the flow to spool a big shaft t4. That is what Precision calls them.

I thought the A was area (of opening) and the R was radius (of the spiral)...? Link to comment Share on other sites More sharing options...
