So when comparing to others all factors are the same. I'm simply saying that if you dyno a given car, on a dynojet, and at first do uncorrected and then do SAE smoothing whatever it won't always be 30 hp difference SAE on my Dyno Dynamics averages 12% lower readings than a DJ using SAE corrections. It all depends on the temp, pressure, and humidity, which I'm simply saying that if you dyno a given car, on a dynojet, and at first do uncorrected and then do SAE smoothing whatever it won't always be 30 hp difference DIN correction factors tend to produce slightly higher results than SAE but are generally considered more conservative than the STD standard. The Dynojet software gives 4 correction options – SAE, STD, STD and STP generally come out with about 4 % higher numbers than SAE since the temperature in the standard is lower in STD than in SAE. 98 SAE, on a friends If you still insist in correction factors, given the fact the dyno temp was 94* F with relative humidity in the 30s%, SAE correction would likely be around 528-530 whp @ about 413-415 wtq. 6. you must always ask what the dyno corrected to or the info is meaningless. STD on dynoSTD will always be higher than SAE because the underlying reference conditions are different. Therefore, the SAE created J1349 in order to convert (or "correct") the dyno data taken, for example, in California or in Tokyo to be comparable to data taken at standard In today's video, we discuss the difference between SAE and STD Dyno numbers, what they are, and why they make a difference.
