How to design the best small 16g turbine inlet for max flow and WG?

[Join]

Hi!

I am currently rebuilding a s16G TD05H turbo. In the process I am doing a portjob on it. But for the turbine exhaust inlet, a guy at work that do 3D programming and modeling is going to help me machine that part.

He also have a Flow program that he uses, but I want to get some more input from you guys with the 3D skillz and flow knowledge how to get the best design.

I want the internal wastegate hole to be efficient enough to prevent boostcreep, but the main flow to get the quickest spool and highest performance is to be as little interrupted by vortex(es?) as possible.

Also it would be nice with some input on exhaust pressure, temps and airflow. Let's say 8000rpm's to have a solid startingpoint.


Just want the better design!


Anyone?

I'll post some flowreports in a while, need to scan them!

This is my air setup: K'N airfilter, stock 2G MAF, gasketmatched S16G compressor housing, 2" hard piping to stock SMIC, 2.5" hard piping to 3" Mustang TB, MAGNUS SMIM, SBR Stg.II Race head w/FP2s, EVO cast manifold w/53mm ID ring into the machined intake on the hotside of the turbo-->outlet thrumpet rounded from 5cm to 6cm outlet, 6cm O2 housing w/2.5" gasketmatched outlet, 2,5" to 3" RRE all stainless DP, RRE High-flow 3" cat, Tanabe 3" cat-back system.

About my previous post: It was to check if I suffer from boost-creep. And I think I managed that part, I think.

BUT, I want to try to up boost as much as possible on this S16G, but I cannot go external.

My stock SMIC is my main consern.

I used to have a 2g mas and I went to 3in gm maft setup and the car spooled faster and the airflow felt smoother throughout a pull.
I think youd find gains with converting to gm maft in blow throw or speed density like dsmonster was saying, as well as making sure your exhaust system is full 3in all the way back, no 2.5 anywhere in it.

The FMIC is definitely going to be your largest gains, the bigger and more efficient the better!
