Message Some things to keep in mind when looking at the chart.....
Both of the cars were tested on the same dyno.
MY car with the EXP90 turbos is running the Nissan auto trans with 250PSI line pressure.... The 2530 car is running a stick shift. .The auto robs a pretty good amount of power.
The only advantage the 2530 car shows, is slight power before spool up. This is because of the difference in auto to stick that you will always have because of the power the Auto trans soaks up.
You can see that both spool about 4000 RPM and after 4000 RPM all bets are off and showing superior power. It is safe to say that my set up in a stick would absolutely spool faster.
I have had 2530's, and 700's in the car before. I can tell you with certainty that the car goes into boost much easier than the older turbo set ups. The turbos feel like they spool much faster than the dyno shows and I believe it is because the turbos are loaded harder on the street.
Both dyno tests were real world with no intercooler freezing, no N20, no nothing artificial.

Enjoy!
