I have the opportunity to purchase a borgwarner r2s compound system for a good price. The turbos that it uses are the s250 and s360. I dont know much about the system other than it's capable of enough flow for 650bhp+. Id like some opinions on this setup before I commit to purchasing it.

There's also a 200hp compound on the 4.5l powerstroke.

03-05-2015, 09:54 AM #2Are there different sizes to R2s? The only thing I see referenced is a 200hp 2.0l diesel.

the difference in induzeer size area is only 1,44, more like you find in a "compound" the more sequential turbo set up like the BMW535D uses wider ratio bigger then 2, I do not know your preference in performance but I do not think it will work that good. The area ratio I use is about two even if it is much more complicated then that, but what the heck it can be fun to try, just do not get disapointed

Damn who wouldnt want that! Could you imagine the cylinder filling if you could get 30psi at 1500rpm.

I think if you saw that on a graph it was probably something with a much narrower power band like a Cummings or powerstroke.

(03-06-2015, 07:31 PM)hooblah Like turbotim said a Cummings or powerstroke, that motor is like 6l if I am not mistaken, If the HP stage was a a vnt kind it perhapes should be possible. BMW the old R2S system to 535D was full boost at 1000rpm, work alone to 1500rpm, together with the big one to 2500rpm and then the big one take over, waste gate open at 3500rpm, the big one is about 50mm induzor size, but the area ratio on that turbo is something like over 2, so I do not think so even I do not know what exhaust house and turbine that are used on them
Below 3k. 1.5k would be nice. I've seen some R2S graphs showing that it was pushing 2bar MAP at 1400rpm, but it didnt mention what turbos they used.

lol ,
if saw them them too , in a caterpillar engine with rpm peak at 2200
or a jonh deere !!!
any how u would like to see it working.....

(03-06-2015, 09:02 PM)TurboTim Damn who wouldnt want that! Could you imagine the cylinder filling if you could get 30psi at 1500rpm.
MAP = Manifold Absolute Pressure.....
--As in referenced to a Vacuum......
--Important word here--Absolute....
Sooooo--
This means 1 bar boost pressure, in real-world speak, and what you'll read on boost-gauge...
Not 2 bar boost or 30PSI! (Err, BTW--2 bar is only 27PSI)
--In example given, Only 13.5PSI....(1 bar)--NOT all that hard to make.....
