|March 27, 2014 - Dyno time!|
Was all that engine swap work worthwhile? Short version: yes. The car spun the rollers at 466 hp and 432 lb-ft. Even better, it was making 300 ft-lb at 1700 rpm and more than 400 from 2900 to 6100. That's one healthy little car.
Here's the dyno run - the whine is from the tires on the rollers.
In other words, yes. It was well worth the work. The old 5.3 made decent power, but didn't have that massive amount of torque. On the road, it's just ridiculously eager, ready to rip forward at any moment. The 6.2 with the ASA cam has the same light feel as the old high compression 2.0 that I used to run, but with approximately three times as much power.
Wow, that puts it in perspective. Nearly three times as much power as the 2008 Targa Newfoundland spec.
