Dr Turbo and JZ...BCI-18 and UHP questions. Got a couple of questions for you guys since you test a lot of turbos.
What's so special about the Garrett BCI-18 Compressor wheel and the UHP turbine wheel? For example, I've seen a few claims that due to their more efficient design, a GT35R with a 61mm inducer will out power a T66 with a 66mm inducer due to the newer wheel technology even though it's smaller. Comments?
Also, same thing about the UHP turbine...even though it's a T3 in the GT35r it's supposed to outflow (less backpressure) than the older turbines. Comments?
Also, what happens to the flow map when you take a stock compressor housing off a GT35r and replace it with a TO4E?
Thanks.
