I love looking at compressor maps! That's super impressive. Efficiency islands are massive. Also sweet it's USA made. Borg Warner turbos are awesome.

When you comsider running a compressor out to the absolute limits, look at the shaft speed. That is the turbine speed too.

[@kylemilligan752]

When the compressor reaches the right side of the map, not able to make more flow, the turbine rpm and backpressure ramp up to force it into the death spiral

[@kylemilligan752]

Most 400 to 500 flywheel HP ls 4.8 and 5.3 combos are pushing the S 475 and s480 compressors off the usable compressor map at 2.0 pressure ratio. Why arent we starting with an 88mm s400 compressor that can actually feed the demands of the engine on the compressor map?

[@kylemilligan752]

Folks complain of the 96/88 borg turbine creating massive backpressure when the 75 or 80mm compressor cannot supply the engine, leading to the overdriven compressor. Look at the compressor map.

Very exciting and looks like an excellence option for reliable bang for the buck. Something forever cool about the S475 family. Intrigued about a potential divided T4 (thinking 1.15-1.28ish) to pair with the 96 turbine wheel. T6 is often not in the cards for our 4g63 applications

Great, I’m going to need to of them lol one for the truck and one for the car with a T4 lmao :)

Will you be going over the sx-r stuff?
