The Twin Vortices Series supercharger took the traditional roots supercharger into the modern era with its highly efficient rotor pack. These blowers became a go-to upgrade for both factory and aftermarket Mustang supercharger upgrades. When it comes to maximizing the performance of these superchargers, VMP Performance is one of the first names that comes to mind. Now the company has stepped up its game with the Gen2R TVS supercharger.
VMP started out by creating smaller pulleys for these units, and that product line evolved into a full array of supporting hardware ranging from belt tensioners to throttle bodies.
In The Beginning
“When I was first getting into supercharging in 2007, it didn’t seem like there were many great options,” Justin Starkey of VMP Performance explained. “I got hooked up with Ford Racing (now Ford Performance), we put the new TVS on my personal car, a 2007 GT500. The blower performed well, was easy and consistent to tune and we could beat the heck out of it on the race track with no issues.”
Inspired by the efficacy of this supercharger, Justin’s creative wheels started spinning. From developing tuning and supporting hardware, he quickly escalated into high-flow inlets and eventually a line of VMP-branded superchargers.
Going from tweaking the calibration to tweaking the hard parts was almost natural for me.—Justin Starkey, VMP
This led Justin to collaborate with the likes of Eaton and others to take the former company’s 2.3-liter rotor pack and fit it into a case designed to provide and even freer flow of air to those efficient rotors.
“I have been able to work with some great people in the industry to help my ideas actually come to life,” Justin said.
Working with those companies led to the creation of the VMP Gen2 TVS, which was a direct replacement for the standard TVS supercharger. It featured a much larger, smooth inlet casting that freed up much of the restriction that held back the blower’s performance. However, even that version could be improved upon with porting, so VMP looked to add those improvements into a new casting.
“We actually wore out the Gen2 tooling,” Justin said. “We had some ideas on how it could be made better—there I go tweaking again—and the Gen2R was born.”
That tweaking involved a new casting that is revamped inside and out. When viewed alone the changes are subtle, but when placed next to the Gen2 TVS that it supersedes, the Gen2R (PN GEN2R; $3,299) inlet is noticeably improved.
“I really like the cleaned-up exterior look; smoother, bolder, and in your face,” Justin explained. “In the performance department, it flows 5 percent more at the upper operating range of the TVS rotorpack. This translates into 20-30 more horsepower.”

• VMP TwinJet 72mm throttle body
• VMP 2.3-liter Gen2R TVS supercharger
“The supercharger is only as good as the rest of the inlet system, so we wanted to pair a bigger inlet with a bigger throttle body to feed it,” he explained. “The dual-bore TwinJet design helps maintain the torque that the TVS is famous for, while still flowing over 2,000 cfm.”
We are continuing to innovate with supporting mods to help our blowers make power. —Justin Starkey, VMP
“We are looking into offering some F-150 specific kits with options, much like our Stage 1, 2, and 3 F-150 kits,” Justin teased. “We are continuing to innovate with supporting mods to help our blowers make power. Next year you will see a VMP fuel system and 10-rib belt drive.”
The future definitely looks bright for TVS fans, but the present is pretty great too thanks to the arrival of the VMP Gen2R TVS supercharger.
