This thread is to share the results of using the Steed Speed TS manifold with various turbos.
As data is contributed, I will update this post. I am also interested to include results of other manifold/turbo combinations for comparison.

- 4th Gear Pull from approximately 2000 RPM up
- List Engine Size
- List Camshaft Duration (Intake/Exhaust)
- List fuel used (Octane + Meth?)
- List Manifold
- List Turbo model and turbine housing details
- List Exhaust Size
- List Road (On level ground) or Dyno pull
- # RPM @ 5.0 PSI
- # RPM @ 10.0 PSI
- # RPM @ 15.0 PSI
- # RPM @ 19.0 PSI
- # RPM @ 20.0 PSI
- # RPM @ 25.0 PSI
- # RPM @ 30.0 PSI

Nice thread, maybe add.....

As that can change things drastically.

Does this manifold have equal length runners (x3) per each scroll? It sure doesn't look like it.

Pei, changing a few things this winter. Basically had a bad vanos for the last two years. New clutch in the works. Ill send you some nice 20khz logs next warm.

This info is way outdated. Merc only ran the log manifold for one season/2014 and has currently been running the equal lengths for the last 2-3 seasons. To also think there is anything similar between the 2 design goals of the engines is a stretch. Merc originally chose the log manifold due to space constraints....ie maximizing rear end aero while knowingly sacrificing some HP. Also, this does nothing to answer my question.
Here's the "log" manifold on the W08.
And the "new" "log" manifold on the SF70H
Why do both of these look equal length? It's because they are.

Hey Guys! I'll add the data we have from one of our 32 psi peak boost dyno runs with the 9180 EFR turbo and the largest 1.45 housing BW offers using the Steed TS mani. Dyno is also attached.

Pei, Add that and graph them. We need graphss.

And this is the data with the exact same setup as the 9180 except with the 8374 EFR turbo and the 1.05 ar exhaust housing.... along with the attached dyno comparison of the 8374 vs 9180...

Also this is fine and good, but might be worth considering some back of the napkin engineering to correct for power/torque.
Thanks John
Updated.
Thanks Kevin
Data added...I'm going to wait for a little bit before updating the list/graph.
You could also add whether logged data is on the street or dyno. Many say response is better on the street than on a Dynojet. This is why I recommended a standardized test that anyone could do — like a 4th year pull from 2000 rpm on a level road and observe 10 psi, 15 psi and 20 psi if you go that high. Knowing the wastegate setting is also important, since the person wastegated to 15 will get to 15 slower than the person gated to 20 will get to 15.
Maybe in the note's add the forum members names to the data. As if this thread takes off like it should, there will be multiple of same setups.

And here is the data we have of 2 E36 stock motor lower compression NEW TS Steed builds we did here at the shop. Both are 93 octane pump gas tuned, but one is an S50 motor with a GT35R and our straight through flow 3" exhaust system, and the other is an S52 with a GTX35R and our Chambered exhaust system which helped regulate boost creep to a minimum. The straight through 3" exhaust system did not want to regulate below 12-13 psi on a 7 psi spring with the OBD1 GT35R customer car, but when we swapped to the chambered muffler design on the S52 GTX35R customer car, we were able to regulate to 9 psi on a 7psi spring with almost identical boost curve and little to no flow loss up top at these power levels.
