The APR RSC Turboback Exhaust Systems were so free flowing the Engineers were able to make safe calibration changes which resulted in the following:

1. Significantly reduced turbocharger spool time over both stock software and APR stage 1 software.
On the days of testing, stage 1 torque levels at 2400 RPM’s were met and exceded at 2000 RPM’s (400 RPM’s Sooner!) simply by running APR stage 2 software with the RSC Turboback Exhaust System

2. Significantly increased and broadened the torque curve compared to both stock and APR stage 1 software.
-On the days of testing, stage 2 torque levels rose 89 FT-LBS under the curve compared to stock software. Peak torque rose from 267 ft-lbs to 355 ft-lbs, for a 88 FT-LBS peak increase.
-On the days of testing, stage 2 torque levels rose 66 FT-LBS under the curve compared to stage 1 software. Peak torque rose from 334 ft-lbs to 355 ft-lbs, for a 21 FT-LBS peak increase.

3. Significantly increased horsepower, especially the area under the curve compared to both stock and APR stage 1 software.
-On the days of testing, stage 2 torque levels rose 50 HP under the curve compared to stock software. Peak power rose from 212 hp to 248 hp, for a 36 hp peak increase.
-On the days of testing, stage 2 torque levels rose 27 HP under the curve compared to stage 1 software. Peak power rose from 235 hp to 248 hp, for a 13 hp peak increase.

All of our data was collected on back to back runs and are the results of average data. Data was also collected on the same car during several days of testing. Gains between runs were in some cases higher but we have chosen to show you an average of what you’ll expect to see as data can change between runs based on countless variables.

Now for the dyno charts of our development progress!
