In our latest BorgWarner test, we’re running the SXE364.5 again. But this time, we’re stepping up to a .91 turbine housing. We previously tested this turbo with a .70 housing, so this is quite the step up.
Like our previous tests, this will be made up of two runs, the first is an unloaded dyno run from 1,300rpm to 3,200rpm. We’ll then do a loaded run with 5,000lbs on the dyno from 1,800rpm to 2,800rpm to get a response time when you’re cruising down the road.
BorgWarner SXE364.5 Dyno Test 1
After pushing this truck up to 3,200rpm, lets see what the numbers from the first test show. Our initial feeling was that it felt a lot like the .70 run. But let’s see what the graph shows.
Peak power for the unloaded run came in right around 570hp. Which is about the same power it made with the .70, which means we didn’t pick up any power. We find that very interesting.
Peak torque for the run came in at 1,204lbs. It definitely felt laggy compared to the .70 at our altitude. As a result, we are liking the .70 housing because it feels more responsive and makes more torque on this engine. You can see this by looking at the graph below.
Based on the results of our first test, we’re not seeing a good reason to use a .91 housing on this turbo on the 5.9L engine. But let’s see if response time is any different in the second test.

The second run shows response time. This gives us an idea of how this turbo will perform if you are towing on the highway and need to accelerate quickly; maybe to pass someone or keep your speed up a hill.
After the roll on, we checked the computer to see how many seconds it took to reach max torque.
You can see from the graph above that the power came in a little lower than the first test, right around 552hp. However, the engine is heat soaked from the first run, so this is to be expected.
Peak torque for the SXE364.5 from the second run is coming in at just over 1,230lbs. And it took about 5.5 seconds to hit peak torque. Which is pretty long.
Below, when we compare the loaded run of the SXE364.5 with a .91 housing versus a SXE362 with a .91 housing. The power is about the same, and the 362 is making a bit more torque. Either way, we are not fans of the .91 housing for these turbos and wouldn’t recommend it as a single turbocharger. We maybe would if you have plans to use it as part of a compound system and needed the big turbine flow.
That’s our verdict. What are your thoughts or questions? Which turbo would you like us to test next? Leave us a comment below and let us know.

I know its not your turbo. But the dps 64 71 12 . I am currently running it and would be interested in the difference
