Between 4500 RPM and 5700 RPM the spread grows to 38lb/ft. Peak torque starts to taper just after 5700 RPM in a linear and smooth fashion, the spread drops to 25lb/ft until about 6500 RPM then smoothly down to 14lb/ft to red line. Below 3000 RPM it only torque delivery only gets worse for the other system, as it builds boost with the slope of RPM. Basically, this translates to between 180lb/ft and 200lb/ft of torque between 3000 RPM and 7200 RPM at a similar boost level, to the wheels. Peak torque on the twin screw occurs at 5000 RPM vs 6500 RPM on the other kit. The twin screw also matches the peak torque value of the other kit 3500 RPM sooner...

I am rounding the numbers down as we use a different dyno with a higher parasitic loss, potentially different weather conditions, altitude, etc. But the trend would be the same, so the spread would likely be larger on the same day, same dyno.

Keep in mind, neither of these kits are 100% polished and ready, components, calibration, etc. can change before final release. As mentioned previously, they have not being tested identically. I do not think the other kit is inferior, it is just different and designed for a different type of customer. Simply weigh the cost and attributes of all the offerings and decide what is right for you. There really is no kit that will be all things to all people, just what you feel will work best for you.

Looks like it, i sure hope they wouldn't make the numbers up.
