Guys,
There seems to be a lot of talk about dynos and power numbers. So figured it was worthy to share a video that I made a while back after a customer of mine showed me a dyno graph that was clearly fake... (or shall we say false)
The dyno graph sent to me was a P1SC car making 1004hp! And as cool as that sounds, I know that is well above the CFM flow limits of that compressor (no matter how fast it was spun), cleaning indicating that something was up...
I asked if he could send me another graph that showed the dyno run data. (Climate, and Correction factor used)
And it was then discovered that his run had a CF of 36%... yes 36% So take away the correction,you have a very legit power number for a P1SC blower. Obviously there should have been SOME percentage of CF, but clearly, the 36% was in error because it produced a power number not physically possible.
So to show this customer how this may have happened, I borrowed a CTSV from a friend and made a little video...
Also: If you guys have any more tech videos you'd like to see, let me know!
Oh and: If you click "subscribe" that makes baby kittens/puppies smile. (just sayin)
NOTE: This is a personal video I made, at my friend's shop and NOT at ProCharger.
ProCharger has (2) climate controlled dyno cells (one with a DynoJet brand, the other a Mustang brand), that maintain about 72 degrees and very low humidity. So our correction factors are usually 0-5% with an average of around 3%. So when a car makes 1,071 with a 2% correction, you know she is making some HP!
We like to use "percentage power gains" in our ads. Because although the "number" might vary from dyno to dyno. The overall "gain" our customers get mimic what we get here in our dyno rooms. (as long as the car was dyno'ed on the same dyno, in similar conditions).
