Pinging VR6 Corrado
Here a dyno chart of a customer that contacted us for our DSR 256 cams. We baselined his car at a measily 144 HP at the wheels or 165 HP at the crank using a 12.5% drivetrain loss correction. We'll HP was down as the car knocked and pinged with an aftermarket chip from "another" popular company. You can see the dips in power as the car's knock sensors were going hog wild and retarding the ignition in attempts to protect the motor.
We'll, first things first, in went the DSR cams. The results were now 159 HP to the wheels or 182 HP @ the crank. Much better than before! HP increased by a nice 15 horses (HP). The pinging was reduced most likely by some of the cam overlap, but things were still not as smooth as they should be.
Time for the GIAC (Garrett Chip). Wow! What a difference. Look how smooth the curve has become! We now hit close to 167 HP @ the wheels or 191 HP @ the crank! A quick test drive and the customer replied, "I didn't know what I was missing :-)"
