The Borg Warner S200 Turbocharger
With a maximum mass flow rate of 55 lbs/min, the S200 is a high-boost and efficient turbo that can flow enough air to support 550 wheel horsepower, yet still spools as fast as most similarly-sized ball-bearing units.
The S200s are perfect turbos for the daily driver that needs quick spool, efficient enough to run high boost on pump gas and flow enough to tear it up at the track on weekends!
Extended Tip Technology (ETT):
By extending the ends of the compressor wheel, Bullseye Power has effectively increased the pressure ratio, efficiency and flow of the entire compressor. This gives the S200 and S300 pressure ratios and efficiencies that can normally only be had with larger, slower spooling turbos.
The extended fins do not hamper spool-up. The compressor wheel is designed to remove excess weight, reducing overall rotating mass. Of particular importance is the reduction of weight at the outer edges which is a major factor for reducing inertia. The weight reduction and where it is reduced allows these compressor wheels to spool FAST.
Map Width Enhancement Grooves:
These grooves allow air to be pulled and fed directly into the second set of blades on the compressor wheel outside of the main inlet. This most notably increases the efficiency of the compressor as well as overall air flow, hence the name, Map Width Enhancement Grooves: it produces "wider" compressor maps. Along with the increased efficiency, feeding the second set of blades directly helps decrease spool time.
Combine that with the lightweight, Extended Tip compressor wheel and that is exactly how the S200 and S300 can make as much or more power than larger turbos and spool quicker doing it!
Compared to a T67, the S200:
- Runs higher boost safely and more efficiently
- Spools quicker
- Produced up to 100 WHP and 80 WTQ more
- Maintains higher levels of power and torque a full 3000 RPM longer
