Last week we told you about Hennessey's dyno test of the Ford Raptor with the new 6.2-liter V8, which yielded 326 horsepower and 343 pound-feet of torque at the rear wheels. That's a 19.5 percent drivetrain loss from the 411 hp and 434 lb-ft Ford tells us we can expect at the flywheel. We'd typically only post one SVT Raptor dyno post, but our friends over at Pickuptrucks.com also dynoed Ford's off-roading superstar, with substantially different results.

Mike Levine and company traveled to K&N Air Filters in Riverside, California to dyno the Raptor, and came away with totals of 344 hp and 361 lb-ft. at the wheel. That's 18 more ponies and pound-feet than the Hennessey dyno run; an increase of about six percent. Further, Pickuptrucks.com says it ran its tests on 87 octane, which reportedly lowers the 6.2's flywheel power numbers from 411 hp to 401 hp. K&N's dyno showed a drivetrain loss of about 16 percent.
While neither power number is likely to disappoint when behind the wheel, it's nice to know that Hennessey's power numbers look to be at the low end of the spectrum. Perhaps that means the 500 horsepower VelociRaptor is more like the 525 or 550 horsepower VelociRaptor. Head over to Pickuptrucks.com to check out the the comprehensive full review of the Ford SVT Raptor 6.2.

      wow different dynos in different conditions in different places with different calibrations have different results. thanks for this amazing update.

      It is funny because you are spamming your site when you don't even have a real domain name and self written content.

      Is this article trying to imply that 411 bhp from 6.2 liters is something to be impressed about?
        • 5 Years Ago
        No, it isn't impressive.
        But that wasn't Ford's objective. They wanted something cheap, that is why there was a retrograde move to 2 valve per cylinder.
        They wanted something with better BSFC than the V10.

        you're telling me your civic has more?

      all dyno's vary, horsepower is nothing but a number that can be manipulated with correction factors.

      this post fails autoblog.

      Probably because the first dyno was in 4th gear which is closer to 1:1 than the 3rd gear the k&n one was in, which isn't as accurate. They did the same thing with the new 5.0 mustang, skewing the numbers by not dynoing in the correct gear.

      Hey Jack! Visit my site!

      Love the Raptor - IMO the best-looking of all the F-xxx truck line.
      • 5 Years Ago
      Quit spamming the site.

      Just keep dynoing it and you can get any figure you want. There are so many correction factors that small changes in results don't mean anything. K&N's very existence owes itself largely to this fact. Do you really think that changing an air filter adds that much HP? You could take the filter off completely and not get as much increase as K&N claims.

      I'm not sure where the idea that the 6.2L doesn't make full power on regular gas came from. It's not fair to the manufacturers to spread this stuff.

        As much as it pains me to side with K&N for anything, in the right (or wrong) conditions, an air filter can make a huge difference. I dyno tune GMs for a hobby, an factory turbo cars air filters are usually hugely restrictive.

        Changing from my stock air filter to an aftermarket one net me 2lb/min more airflow. That's quite nearly 20 whp

        I have to agree with Nick on this one I've witnessed it to many times to call it a fluke a properly done cold air intake or ram air intake can net quite a few hp even on a N/A setup I've seen as high as 14whp gains and generally around 8-10whp throughout the range. On turbo cars the effect is even greater as they can take advantage of the cooler air that comes in aswell as the increased velocity. My friends MR2 turbo dyno'd at 185 stock with a tune ran to about 196 and with the intake and a ecu tune put it up to around 212 then on the final run (for now) with a boost increase is putting a healthy 245 whp. Thats on factory everything except the intake and ecu tweak.

        Does your Firebird weigh 6,000 lbs?

        Were those Raptors using the 6.2 or 5.4?
        Was the rear differential locked? (if only using rear drive) Were they in 4x4 (otherwise)
        • 5 Years Ago
        This isn't a street truck, it's a dedicated off-roader. With four-wheel drive and some serious tires, this thing will put all its power down.

        And stop yelling. You look 'tarded.
