When Cruiser got the big cruiser way back then, it was a nameless, bone-stock, 1999 VN1500 Classic, generating a mere baseline horsepower of 45.8 at 4000 rpm, with a grunty 65.1 foot-pounds of torque kicking in at 3000 rpm. But the balance of power began to shift with our installation of Thunder Mfg.’s Thunder Air Kit, which yielded a freer-breathing system and an increase of more than 10 percent in horsepower and torque. We were even more stoked that we didn’t sacrifice any driveability with the added power. A Dyna 2000 high-performance ignition module then entered the fray, to unanimous, thundering applause. With a straightforward installation and 10 ignition curves to choose from, the Dyna improved the Vulcan’s power and torque curves even more noticeably, and threw in a couple of more horsepower to boot. Its flexibility and variety of options were a pleasant surprise to everyone.
