Just wondering what size of T04E everyone is running here. 50trim? 57trim? Bigger?
I was planning on going with a 60-1, 60lb/min T04E but I think i may go bigger. Given dyno charts i've seen here.. my goals will not be acomplished with a 60-1.
Edit: Just to clarify, a 60-1 turbo flows 899CFM @ 1bar.

I am running the Lindsey super 61 T04e polished with 8 housing.

Haven't installed mine, but its a T04E .57 trim, replica 8 hotside with water cooled center. Also has custom work to the intake side to match it to the 951 engine well.

Interesting.. what size/stage turbine wheel?
50trim flows 47lb/min and is a 54mm Compressor wheel.
57trim flows 49lb/min and is a 56mm Compressor wheel.
60-1 flows 61lb/min and is a 60mm Compressor wheel.
Of course there are tons of diffrent types of turbos, using diffrent types of turbine wheels. Stage 3,5, and P Trim.
I'm trying to get a feel of what turbo I want to go with, I may try something diffrent as well.

Not that I know what it means, but mine is stage 3 wheel as far as I can recal. (I really am under educted on turbo stuff. Someone teach me what .57 trim actually means!)

I am thinking about going with a Dual Ball Bearing T04E 56trim.
56trim flows 65lb/min and is a 61mm Compressor wheel.
(don't ask me why the 56 trim flows more than the 57 trim)
Then again, I may go big...
63trim flows 75lb/min and is a 67mm Compressor Wheel. (basically a T04R shoved into a T04E housing
) For comparison's sake.. it flows 1088cfm at 1 bar
56trim flows 65lb/min and is a 61mm Compressor wheel.

I'm still learning. I think the "trim" is just a refrence to what size of compressor wheel it has. Most of the time they are pretty close.

"Trim" is just a ratio of inducer and exducer diameters on the compressor wheel. For example, a compressor with a 54mm inducer and a 76mm exducer comes out to be about a 50 trim. At the same time, a compressor wheel with an inducer of 45 and an exducer of 63mm is also roughly a 50 trim, but would not perform the same.
The trim equation is:
((Inducer diameter^2)/(Exducer diameter^2))*100
Because trim is just a ratio, a 56 trim can flow more than a 57 trim.
