CORSA 3\" dyno results from APEX Motorports!!
As many of you know, APEX Motorsports tests every power upgrade for the Viper using our in-house Dynojet and engine monitoring software. Since Dynojet's are very sensitive to temperature, humidity, and input variables, and the Viper is extremely sensitive as well, we take careful steps to ensure testing conditions are as consistent as possible. We also feel it necessary to test performance components to see if they stand up to their claims for variables like increased power and torque.
Since we install these parts on our customers' Vipers, we need to be able to tell them what to expect, and there are instances in which manufacturer's claims don't hold water. With our dyno results, we also like to take the average increase numbers by canceling out the highest and lowest readings, and taking into account average gains, as opposed to peak gains, throughout the entire rpm band.
So, we have had the opportunity to do a 'back-to-back' test on CORSA's 3" exhaust system. This test was performed on a 96 RT/10 (GEN I motor with rear-exit exhaust system). This car was stock except for filters and tubes (a mod that everyone should have), and we performed 7 dyno runs to ensure consistency. We should be completing results for a GENII in the next week.
Results follow below:
Difference (before/after)
RPMS hp tq
2500 3 6
2750 4 7
3000 5.5 10
3250 8 13
3500 12 18
3750 12 16
4000 13 17.5

5000 20 21
5250 21 21
5500 26 27
PEAK: +19hp , +17 ft.lbs tq
Looks like to CORSA system preforms great!
If interested, you can purchase the system from APEX Motorsports. Call us at 408.562.1000 with any questions.
Thank you.
