We Took the 5.2L Predator-Powered Mk4 to the Dyno

Posted on July 25, 2024 by Dave Lindsey in What's New

We built this Mk4 Roadster with the crew at Hot Rod Brothers the other year, and it features the 5.2L Predator supercharged motor along with Tremec 5-speed transmission, IRS, and 17″ Halibrand wheels. Factory Five tech Dan G. took the Roadster up to Cohesion Motorsports in Lawrence, MA to tune the engine and see what it would do on the dyno. Check out his report in this video.

The results were 654.4 HP and 533.8 trq which is right about where it should be for the stock Predator engine. And remember, this is in a car that weighs right around 2,400 lbs.

Check out more photos of this Roadster build here.

Thanks to the crew at Cohension Motorsports for their help at the dyno!
