It often goes that once you get a taste for horsepower you’re never satisfied with any amount as just “enough”. This holds true for the guys at VMP Tuning, and especially for their resident mad scientist Justin Starkey

Not long ago Starkey bolted a VMP TVS supercharger to his personal BOSS 302. He added to that a VMP eight-rib conversion for the supercharger, which allows it to make 17 psi of boost. Another key to the BOSS’s big power gains was VMP’s high flow inlet elbow, and JLT intake which allows the big TVS to draw in even more air.

That combination of parts, combined with Starkey’s masterful tuning yielded a healthy 793 hp to the rear tires. While Starkey was probably happy with it for a few weeks, like all of us, he was looking for more, especially with the 800 hp number dangling out there as a carrot.

Recently Starkey added VMP’s Twin Jet 67mm throttle body to the mix, the improved airflow to the supercharger was just what the doctor ordered. Back on VMP’s Dynojet, the BOSS again spun the rollers, but this time churned out 837 hp at the rear wheels, an improvement of 44 hp at the rear wheels.

Starkey documented the gains in a recent video, and points out that it’s a combination of all these parts working together that yielded the results he was able to achieve, however the Twin Jet throttle body seems to have made a huge improvement with a very simple bolt on upgrade.
