Did a quick seach, couldn't find the answers to my questions, so hopefully one of the experts on this site can enlighten me..

1) How's the power curve of the ATI installed, does it add more low end/mid/top end power?

2) How smooth is the dyno curve, does it spike at all, if so, where? I seen ATI's released dyno sheet but I don't believe them since they are always false or exagerated.. ?

 

Here's mine dyno for HP:

 

How is the power curve installed??? Do you mean where do you see the most power at??? Well it's pretty much everywhere, but mostly mid to high end power gains.

 

Oops, sorry, I guess my wording was a bit off.. what my question was.. How's the power curve after the install.. some turbos (Is300 especially) you see a smooth curve, then it just shoots stright up at roughly 3,500, so I was wondering how it compares to a supercharged Z.. I understand the supercharger gives constant power, vs the turbo which doesn't..


And Mr Bonz, could you please post the dyno sheet again with the RPM's x axis in view? And if you have a baseline it'd be very helpful. Thanks!

 

With this SC, centrifical, the boost increases as RPM's increase thus it is a graduated hp gain thus the dyno sheet results. You will not get the sudden, all at once spike of power as a root type SC or Twin turbo often have. Some people want the power all at once but others might feel having a gradual power gain such as the ATI SC is better for track etc...

The torque curve is pretty erratic on my sheet, but I think it was because the rpm pickup was getting some false signals.
