Dyno Comparisons: Dynojet,mustang....

Like the title says: I've been talking with a lot of different motor builders / Dyno shops trying to get a somewhat accurate calculation on all the popular Dynos E46Fanatics forum members use. There has always been some confusion when one forum member posts great results for his/her Bimmer, and then another forum member with almost or exactly the same high performance parts yields a way lower (or higher) dyno number. The fact is, different dyno manufactures yield different dyno results. I recently came across this comparison online, based on my research it's pretty darn accurate.



Now on to the comparison:

"Here is how the various dyno manufactures relate to one another. This is just a comparison of numbers output assuming the same vehicle on the dyno.

The industry leader in number output by far is Dynojet. Their marketing in the mid-90's specifically used the larger output numbers as a selling item.

Next is Mustang, generally about 7% less than Dynojet numbers.

Superflow is about 3% less than Mustang.

Dyna-Pak and Dyno Dynamics are about 3% less than Superflow.

Ok lets make this point again to make sure it's clear. The SAME CAR on the DIFFERENT DYNOS. So our test vehicle output on the various dynos are as follows:"

Dyna-Pak/Dyno Dynamics 200hp
Superflow 206hp
Mustang 214hp
Dynojet 226hp

I hope this helps the next time a forum member puts up dyno results & you're trying to compare them to your results, or someone Else's.

In the end it's not about the numbers, it's about how well your Bimmer is tuned; and how well it works against the competition. (if you have some)


Good luck.

One other thing. No matter what, keep using the same dyno if you are tinkering around with your car. That way, you at least you can eliminate one variable.

Also, in racing, everyone else has more power than you. The only reasons why you can keep up is because of better braking and handling.

so theoretically I dyno'ed 225whp on a dyna-pak, I should be around 250 whp on a dynojet... hmm I'm curious to try this!

Depends on the kind of racing, but sometimes the races are won in the straights

less time in the corners... more time on the throttle
