4th Annual Viper Club Dyno Day Wrap-Up

[Brandon@DC Performance]

A dyno separates the men from the boys and we were happy to host the Viper Club for the 4th year to allow everyone to measure their... well... horsepower.

From Rick Hollis' 850 rwhp 9-second daily driver to a Dodge Neon road-racer, the dyno gave a the cars their report card.

21 vehicles were dynoed between 9am and 2pm including Anhtuan Pham's naturally aspirated 2006 Gen 3 Viper equipped with DC Performance's Stage 3 SuperTuned package which laid down a whopping 580 rwhp!

Great people, good weather, and better-than-average BBQing by DC's own Tony Parr made for a very successful 4th Annual Viper Club Dyno Day @ DC Performance and we'd like to thank everyone who helped make it such a special day.

Personally, I think the higher torque number is a better way to classify as "Best Stock" on a Viper >w

Lawrenzo,

Best way to think of a dyno number is as a "snap shot" of your car's performance at that instant.  Things can and do change from one day to the next and even from one run to the next.

It can be fun to bench race though.

I did find it interesting that generally the Gen IV cars seemed to do better after 4 or 5 pulls while the Gen III's tended to produce best hp / tq at pull 2 or 3 and Gen II's made best power at pull 1 or 2. 

Power loss due to heat soak seems to be improved in the Gen IV engine.
