Sorry to add to any confusion with that question. Thanks for the clarification.
For you guys that have installed and used this SC setup, what are your opinions comparing this to the Kraftwerks? These are the two that I am considering and was wondering about the differences/advantages of the SOT.
Thanks for the continued input on this!
Can not really comment on the Kraftwerks setup, but I much prefer my boost/power profile over CTSC and VTSC cars I have driven and ridden in.

I was originaly looking at the KW setup befor I took the plunge to go with SOT.
Here you go you can come to you own conclusions.
KW data was pulled directly form there website.
I can only compare the low boost KW setup at this time since we do not have a SOT dyno at higher pressures then 6.8lbs of boost at this time.
Not trying to say anything bad here, I have seen a roots style torque curve and the one for the SOT seems inaccurate of 200 tq from 1000 RPMS on, you have to build it at some point.
I extrapolated the TQ down from the lowest data point that has been gathered so far.
Approx 2700. for the SOT
In a real world application the TQ below that would defiantly ramp up because of your ramping of the throttle.
AKA you would not just floor it at 1000 rpms.
However if one was to go 100% TPS at 1000 then the torque would = what I have shown. Not like you would move any where because of clutch slip/ wheel spin however the theoretical TQ values below 3000 do parallel what one would expect to see in the real world if one was able to dump the throttle at 1000rpm.
Did the same thing with the KW populate the power curve down from 2500.
Excel extrapolates the numbers based on its understanding of the pattern the inputted real numbers demonstrate and the boost profiles equations programmed in for centrifugal compressors and positive displacement superchargers.
