We took the Drakan down the road to our neighbors at
Cunnigham Motorsports the other day to get a bit of tuning done. Out of the box, the GM E-ROD runs really well with our setup. We were not looking for more power from the tuning. We mainly wanted to verify that our tune was not negatively affected by our intake or exhaust solutions and the it was safe enough for the abuse this car will see on the track. Also, GM claims the E-ROD makes 430HP at the crank but we were very curious what our car was actually putting down to the ground via those big 315mm R888s. After a couple of runs, we found that the GM tune is actually pretty good but the guys at Cunningham were able to clean up the air-fuel ratio a bit as well as find us a few more horses. The final peak RWHP number was 412 hp and final torque was 411 lb-ft. To put this in perspective, the very fast 2015 Z06 has about 575 RWHP and weighs in at 3524 lbs, this gives the 'vette a power to weight ratio of 0.16. Not bad, but the Drakan beats it handily with a ratio of 0.21. Of course adding more reliable power to an LS is easily done...not that it needs it!
