S400 100mm FI Turbine

Anyone play with the s400 100mm turbine from FI yet? Should be ready to test the new 491/100/1.45 in a couple of months on a compound setup with an sxe 472/87/1.0 on my LBZ. We are excited to see what it does. Coming from a 369/74/.90 & sxe 488/96/1.32 setup, I think it will definately breath easier.

Pics are the 88 next the 91 and the turbine differences.Click the image to open in full size.Click the image to open in full size.Click the image to open in full size.Click the image to open in full size.Click the image to open in full size.Click the image to open in full size.

I asked the same thing and was told no. It is a custom wheel they have been working on for a few years or so.

I've heard that the 96 turbine couldn't drive the 88 and up comp wheels, I'll be watching this.

If 100mm is the inducer it could be a gt50 tw. I've attached your pic beside a pic of a gt50Click the image to open in full size.Click the image to open in full size.

I wonder if this 88mm inducer comp wheel SX-E will outflow the 91mm comp wheel but you never know if you change both ends compressor and turbine.

The XS4 turbine will drive the 88mm comp wheel SX-E but lacks top end power compared to the S500SX models but for some they will not be able to spool the S500SX that easy so the S488SX-E will be the solution.

I stated I wouldn't be surprised if the FI 88mm wheel made more power in a diesel application, I didn't say it would flow more than the SX-E. Flow is not a direct factor of power if you entirely exclude pressure ratio.

In all delta pressure will move gas in general and we call this flow most of the time and some engines are more sensitive to back pressure while others are not in close relation to EGR or no EGR most of the time but about this some can write a book about it.
So still the question remains than will this bigger turbine be a better upgrade using the 88 SX-E comp wheel?????? What I found out is that bigger comp wheels move slower moving the same air mass reducing turbine speed creating backpressure even so is there any data on this? Hole for the speed sensor is there to easy job done reading RPM on these two units making data.

But yes like the idea of using the turbine from FI to fill the gap between S400SX4 96/88 and the S500SX 110/100 turbine.

I remember hearing about the larger turbine before I switched over to the GT55. Took a while to get it out finally looks like. Hopefully it's the cheaper option people have been asking for.

GT55 is 111mm inducer, GT50 is 100mm and by the looks of it that is almost what they have copied.

Be curious to see how this turbine would compare to the 97/92mm HX60, wasn’t it sort of the standard out of the S400 96/88 and the GT50?

It's easy these days, you can choise whatever shaft and ask them weld whatever turbine you like to it.
