Anyone think bd's dyno in Abbotsford is correct

[zachattack]

Yes no maybe so ?

 

[khaoskustoms]

It was accurate when i dynoed my dakota on it.

 

[huck25]

Is there a reason you think it isn't?

 

[DISTURBED]

Probably added up all the ad on's and got 700 hp and he dynoed it at 400 would be my guess.

If you pull the correction factor out it is typically pretty close. I have run on it at least a dozen times over the years.

During a dyno day not really, set up for your truck as a dyno session yes....

Well last June I ran 430hp with 33 inch tires this October ran 396 with small winter tires

 

[Tate]

If you dynoed on winter fuel, you can expect a hit in the numbers.

 

[fire power]

If it is an inertia dyno the tire size is what did it

 

[zachattack]

Mustang dyno not sure on the winter fuel or summer

 

[Kronic_187]

It's bd, if its anything like their products its junk

 

[LReiff]

Mustang dyno + winter fuel = power drop. Throw some cetane in it and run again!

Incorrect....
Tire size only affects where power is made and the overall torque number because of it.
JetPilot and I spent a day with various tire sizes at DGR along time ago and all we did was move the HP number up or down in the curve and raise and lower the torque number.Larger tires tend to kill torque and smaller tires will elevate the number..

Sounds like winter fuel and air quality made the changes on him.
