On The Dyno

We knew that the combination of a Whipple 4.0-liter with a fortified Trinity engine would generate big power, but we didn't quite expect the number to keep rolling this high into the four-digit range. Suffice it to say this is a happy marriage. Seriously, we were impressed when the Trinity 5.8 picked up 153.42 hp and 144.22 lb-ft of torque with the typical pulley, tune, and exhaust bolt-ons. Color us astounded that the built motor with 24.80 psi of Whipple boost—courtesy of an ATI 15-percent overdrive balancer and 3.50-inch blower pulley—tacked on an additional 440.98 hp and 331.09 lb-ft of torque. Some cars would be considered fast with those numbers as their total power and torque numbers.

"This is the most powerful car we've owned so far and it seems like it really didn't take that much to get there. I think the biggest factor with this car as opposed to our '10 GT500 is compression. When we built the '10 with both E85 and high-compression these engines weren't that popular. Shortly after that car was finished is when people started building motors with higher compression," Jared explained. "So for our 2013 we did just that and built a high-compression motor knowing that it would make more power with less boost."

The next stop after the build’s completion was the dragstrip, so it was a great idea to install one of BMR Suspension’s driveshaft safety loops (PN DLP001; $239) for safety and dragstrip rule compliance. 5.0
