Some new bad *** turbos that I have seen on winning pro teams' cars.
Bulls eye racing and Borgwarner teamed up to produce this extended tip 50 trim turbo that makes all other turbos look like turds.
By extending the ends of the compressor wheel, BorgWarner 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
Another factor that increases the efficiency of the turbo as well as overall flow is the height of the compressor wheel blades. The BorgWarner extended tip version is over 20% taller than the standard 50 trim. The theory that the longer the air stays on the blades the more boost you can run and the more air it will flow thus improving the aerodynamics of the turbo. This extended tip compressor wheel is rated at more than 55 lbs/min vs. the standard 50 trim at only 49 lbs/min.
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!
Compressor Maps
You can clearly see the difference when you compare the compressor maps. Its not hard to tell which one is the extended tip turbocharger. Notice how the map is taller and wider, the new extended tip 50 trim can move more air and run higher boost pressures that the older square back compressor wheel.
The S200 and S300 turbos used in conjunction with our exclusive Bullseye Power custom cast stainless steel turbine housings, afford a direct, bolt-on install for nearly any application. Turbine inlet and outlet options include specific engine makes as well as standard T-3 and T-4 flanges.
Our huge 38mm internal wastegate ensures solid boost control without the hassle, added expense or noise of using an external wastegate.
The S200 turbocharger was tested on a well-supported 1998 Acura Integra that previously sported a T67. In this dramatic comparison, it is clear to see that the S200 was not only able to safely run a higher boost level, but also spooled much quicker to that higher boost level, creating much more usable power that began at lower RPM.
While the S200 was able to safely run up to 32 psi, this chart shows an S200 at an efficient 30 psi pull compared to the T67's maximum efficient boost level of 25 psi. The tune for the S200 only differed from the T67 tune by adjusting AFRs where needed to maintain a safe ratio.
Total area under the curves show the true performance potential and it cannot be any more clear that the S200 produced a huge increase in area under the curves. The shaded areas of the chart show gains afforded by the S200 over the T67. Looking at the chart, both the horsepower and torque curves of the S200 are much higher across nearly the entire power band.
There is a gain of 100 wheel HP at the point where full boost is reached. Likewise, there is a gain of nearly 80 wheel torque at the point of full boost. The increases in extra power and torque begin immediately upon getting into boost, which is noticeably earlier as seen by the S200 curves being further to the left than those of the T67. The S200 maintains more power and torque nearly everywhere in the power band. As can clearly be seen, the T67 cannot come close to the S200 levels until near redline!
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

Re: Some new bad *** turbos that I have seen on winning pro teams' cars. (Blitzkrieg)
so the s200 @ 30psi made a good midrange gain over the t67 @ 25psi. Were the trims and all other factors the same? If so it seems to be a very nice street turbo

looks like some great promise with these turbos!

That test is bullshit, you can't compare 1 turbo at 32psi to another at 25psi and talk about how much more midrange it has with the same peak power....

Um I think the other turbo with 6psi more boost was smaller the thread that I saw that graph from was a thread TheShodan made.

Re: (MidShipCivic)
It doesn't matter, there is absolutely no logic in comparing power output with different turbos at different boost levels like that. I know for a fact that a 67mm compressor wheel will make power past 25psi. It says that's the max boost for that compressor. How can you convince yourself that that was a fair test?

You are totally right Tony, that test is kinda out there. I plan to test my GT4088R vs GT4067R and a Borg Warner S366 turbo in the next couple of weeks, we shall see. The test is AS CLOSE as I can get it since of course the specs aren't exact on each of the turbos BUT very close, we shall see

Wouldn't that be "I'm all eyes." Since you will be reading it and not hearing it?
sorry had to, my dry humor

How much better usabilty of power will you see when you exceed the max power levels with the T67 of that S200 at that specific psi above?
I just see a good turbo for 550 whp with some decent tq.

Better no is power turbo big?
