Got a 64.5 on the way.
Building new compounds?

That's exactly the flange adapter I had from SPS... Blew it apart at 15 pounds of boost 5 minutes after having it on. Just welded it and now all is good.Picture of the flange adapter.
I should add that the elbow/clamp is actually cheaper than the flange adapter.

testing it in place of my current superB special over GT55.

Everyone scared of the 369? Nobody seems to post anything about them.
I was about to run a s369sxe over a 484 and based on what Jose at forced told me and the reviews of the 66sxe that there wasn't much benefit to go bigger.
Is that in general, or just in a compound system?
Hope this helps on the S369SX-E.
The S300SX-E uses the same turbine wheel dimension (79.76/73.37) as all previous S300SX3 units. The wheel was re-designed for an improvement in efficiency, but there has been no real change in peak flow.
It is obviously going to have a lower peak flow (and efficiency) than the 83/74mm S400SX3 turbine wheel.
The SX-E wheel compares similarly to the EFR9180, so you could use MatchBot to compare them.
The 69/91mm FMW compressor, however, does have excellent flow and efficiency, and for that reason, it should compare very well to the 177248, but again, turbine flow will be the point of restriction on that unit, which gives the larger, S400SX3 some advantage at higher pressure ratio. In many cases, particularly with smaller displacement, gasoline engines, this smaller turbine is an advantage.
The S467SX3 or 178855 comes close to the S369SX-E in max flow and spool-up but the 177248 got a bit more flow left on hi pressure ratio’s
So if I read that right a 66 has more flow than the 467? Correct ? I have been debating the 467 for strength and I can use it as a single before I get the 485. Just something I have been thinking about
No the S366SX-E has less flow than the S468SX3 and S471SX3 on a 3.4 pressure ratio but on 4.2 to 4.6 pressure ratio the S366SX-E dos better compared to the S468SX3 and also the response will be better on a small engine with the S300SX-E series.
The S468SX3 has the same compressor wheel as the EFR 9180 series.
