Just went to Allspeed in Peachtree City, GA to get a baseline dyno of my 06' 6MT. This was my first dyno ever, it was on a dynojet and I was expecting between 220 and 230. I was pleasantly surprised at the results

 

how much do they charge?

 

$25. I didn't mind spendin that much.

 

$25?!? That's it!?!? Wow, awesome deal. And good numbers on the dyno!

 

thanks, I should be getting more done as I add things to the car.

 

sae or std?

 

For a dynojet that's about right! Great deal. $75 for four pulls up here.

 

$25 is cheap!

 

$25 is incredibly cheap! Usually $40-$50 for 3 pulls and that's the discount rate for dyno days (normally requires 10 or more cars)...

 

At $25 for three pulls, how do they stay in business
Great price for you. Here in Calif, as OCG35 says for Dyno Days is correct. No group price, about 75 to 125 bones for three pulls depending on shop.
Nice numbers, but is that SAE corrected?

 

I'm still not sure if I understand the SAE corrected numbers. Maybe one of you could explain this for me? The numbers I got were straight off of the graph, nothing done to it, and it was done on a dynojet

 

Here's an article about the whole Dyno processes. Good article, but long.

Quick copy/paste of where SAE is used and how/why:

Once they have these numbers a series of correction factors are applied, some made public, some hidden as proprietary secrets. The public correction factor is the SAE correction factor. This formula assumes a mechanical efficiency of 85%. The formula used is: Where: CF= 1.18 * (29.22/Bdo) * ((Square Root(To+460)/537)) – 0.18. To = Intake air temperature in degrees F, Bdo = Dry ambient absolute barometric pressure. This correction factor is meant to predict output in varying atmospheric conditions and is a +/- 7%. The proprietary correction factor is supposed to reflect the loss of power from the crankshaft to the rear wheels.


Standard numbers are usually higher. SAE corrected numbers are usually lower compared to standard.

 

at the top right of the dyno graph it says in bold letters CF: SAE Smoothing: 0

on the bottom when it lists the stats of each pull (Run Type, Run Conditions, Humidity, etc.) it says at the end SAE: 1.02

does this mean it is SAE corrected?

 

Dang...not bad for $100+ baseline dyno....

 

Wow $25 is less than any dyno day deal I have seen!
