Once upon a time, there was no need for rev limiters. Those days are long past us though, from Formula One cars revving to 14,000 RPM to the scooter putzing around your block, most vehicles these days have some sort of electronic rev limiter. That includes the 2011 Mustang, which tops out at 7,775 RPM, though normal rev limit is set at 6,800. A healthy redline for a 5.0 liter V8, no doubt, but there’s always that desire for more.

This video and dyno graph come from JPC Racing, who put a 2011 Mustang on the dyno and revved it well past the redline, up to 8,200 RPMs. So how’d the new 5.0 handle it?

Like a champ, though that certainly has something to do with the work JPC Racing put into the engine. This wasn’t any stock 5.0 (though it was on the stock ECM, hacked for a higher redline.) Rather, it was an RGR build, which is a complete 5.0 short block with fully forged and balanced internals, coupled with a BOSS intake. This one-two punch put 477.7 hp down to the wheels near the stock redline, and hovers above 450 hp until about 8,000 RPM, where it drops off considerably. So that you really only get to use about half of that extra 425 RPMs. The sound quality of the video isn’t great, but we bet those extra RPM’s are good for some extra V8 growl too.

Still, who wouldn’t want bragging rights to an 8,000 RPM small block Mustang? Just further proof that the new Mustang is a resilient little muscle car, and the 5.0 engine can handle a hell of a lot of revs and power.
