The Dynajets I've been tuning on read pretty low. My FRS baselined at 150 whp (6 speed). Another I tested the owner's car baselined 159 whp. For NASA testing I use these because they don't read far off a Mustang I also use so if I use the Mustang and have to add +10% it's a big penalty.
It's really just about the delta so as long as you have a good baseline any dyno will do the trick really. Customers don't always see it that way as it's more glamorous to use a dyno that gives you an extra 30 hp even though the delta from stock is the same. Thanks, Phil Grabow |

Definitely need to be careful. There is a part I didn't include that states that the results need to be "repeatable". I read that as you better come up damn close to your declared numbers if we call you for verification tests.

I am also noticing a trend on this forum for using "standard" correction instead of SAE because it will result in a higher number. I also notice the trend of not including a stock baseline pull or even noting what the power is.
It's all fine as long as know the delta and the reader can see that 190 hp on one dyno is really the same gain as 170 hp on another. |

The FRS is a weird car. My Dynodynamics USUALLY reads lower than a Dynojet, but I pull the FRS in fifth (1:1), and getting 159 to 168 for STOCK ones. Which seems very similar to Dynojets, but noticing a lot of Dynojet guys pull them in third??? |

Ive known that dynopacks read lower than others. the OP says the average is higher but doesnt clarify. it all depends. For instance a high horsepower car on a dynoject with no weight on tires read lower than dynopack. the slipping and stuff makes it low. cant get it to roller. therefore dynopack is more accurate for that. A lower horsepower car on a dynojet is fine. as for saying ALL cars avg higer on dynopack, there are so many factors to consider. It just isnt that simple.

For boosted application 3rd gear is too short. I've tuned all over the country and even the same dynos will read different from location to location. The AWD Dyno Dynamics I use in Seattle reads the same as the local AWD Dynojet. I remember tuning on a dyno and getting really high numbers. I even told the customer it seemed too high. Later I found out it was in STD correction vs. SAE and the difference was +5% which is huge on a 650 whp car. I think the temperature can make a huge difference in the SAE vs. STD correction. |

So far I have try both the dynojet & Dynapack on my stock car. both show about 160whp (on pump gas).
Dynapack is good for places where we cannot dig a hole on the ground. |

Who says you have to dig a hole for all other dynos.
