Yes, sorry my mistake, i meant the SPL as in the latest design i.e. BB 76mm inducer. I have a habbit of mentioning KAI when refferring to the T51r.

Just a bit of info on the BW extended tip 480 :-

 

"S480 80mm Compressor wheel, 96mm Tubine wheel, T6 1.32

 

By extending the ends of the compressor wheel,we have effectively increased the pressure ratio, efficiency and flow of the entire compressor.

 

This gives the S200, S300 & S400 range 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."

 

1200hp capable and a price tag of $899

 

It may be woth looking at the smaller BW turbos, especially at the prices. and heres a 20 odd page thread on them including test results, dyno's etc etc
