Just got back from the dyno!! Stage 5 AMS + Zero Clearance results inside
I knew the car was fast when I drove it on the street. Even I am a bit shocked at the dyno numbers!! Almost 50WHP gain over normal stage 5 YIKES!! Just think what we'll be able to do with these turbos once we get a chance to get tuning done specifically for them! The car still needs some tuning to get to it potential in my opinion. I have the feeling that there is a lot left in it, especially in the low end torque (which has never been a strong point on the AMS turbo kits).
This car was running on PUMP Gas (92oct).

NOTE: Peak HP was a FULL 1000RPM Sooner with the ZC! Torque numbers
Here are the normal Stage 5 dyno results for comparo: (Keep in mind that the car below started at a lower RPM and the graphs are not to the same scale)

Yeah, i'm a bit surprised at that too but the tuning is not specific for these turbos
and my feeling is that the car doesn't know what to do with all those CFMs! All this shows is that these turbos will need some ZC specific tuning to get the low end torque advantage.
