Z-Eng and 256 cams on 93 VR6 Corrado
Here is a chart of before and after the install of the Z-Engineering Kit on a '93 Corrado VR6.
Believe it or not, this Corrado was only dynoing at 148 HP @ the wheels before we added a set of DSR 256 cams to it. Then, it dynoed just a bit over 160 HP. Sure, it didn't start out as the strongest car but, boy, look at it now!!! 230 HP @ the wheels and an axle twisting 207 ft-lbs of torque!! We estimate a conservative 263 HP and 237 ft-lbs of torque at the crank with a realistic 12.5% drive train loss. If we corrected using 15% (which we feel is a bit high), we'd be looking at 270 crank HP!!!
We also used a bit of GIAC magic as Garrett custom programmed a chip for this bad boy! Weighing in at 2700 lbs and mated with the Corrado's 3.69:1, the car is a serious terror. We expect quarter mile times in the mid-13's if traction can be held.
