What is the biggest difference in power measurement you've seen between dynos? Weird question, I know.

 

Too many variables come into play. Not to mention different brands of dynos will read way different than others. Use it as a tuning tool and not an absolute measurment of your power.

ive ran a dynojet 248 and all the other dynojets in the area came close the same numbers with the same car. apparently the different brand dynos are slightly varied in there hp readings. i had a guy come in with a gto that made a consistent ( within 2-3 hp) number on a mustang dyno i believe, and then on the dynojet that i ran the car made consistent hp numbers but were 15 hp lower.

 

what's a dyno?

 

Sorry for my poor wording, but that was actually my question:

What is the average difference between brands of dyno (Mustang, DynoJet, etc.)?

 

All depends on the settings. At the same elevation, all dynojets should ready very very similar (in fact I've witnessed the same car on 3 east cost dynos on the same day make the same power on all 3 dynojets). All the others, all depend on the operator. Dynojet has automated environmental readings that are pretty much foolproof, so they all read the same. All other types of dynos require input of form or another and depend on the operator. I've seen the same mustang dyno read 50 high (compared to dynojet) on one car and then read 30 low on another.

 

i think this is the dyno jet everyone keeps talking about.

 

Thanks. I'm having an argument with someone who says a difference of more than 15 hp is impossible.
