Dyno Condition Confusion

unlicensed to drive · March 30th, 2009, 09:33 PM

I know SAE usually reads higher, but I've heard STD reads higher in certain conditions. On a 302rwhp STD CF dyno run, with conditions being 100 degrees fahrenheit, 17% humidity, and 29.44 in-Hg(posting in case it matters), what would the numbers be in SAE form?

No, STD reads higher.

I'm asking though, in those conditions what would SAE read. I just thought that in certain air temp/humidity, SAE would read higher

you...since when do sae corrected dyno's read higher than std corrected dyno's...

06GTMustang89 · March 31st, 2009, 12:14 AM

agreed SAE will always be the lowest compared to STD...

unlicensed to drive · March 31st, 2009, 12:15 AM

I never SAID they do, I was asking if in the specific conditions of that dyno run would they. I don't know much about correction factors, so this is why I asked.

i know im just messing with you man

Oh ok, I have trouble pointing out ball busting in a thread where I'm asking a important question. On that specific dynosheet, the power drops off right before 6500 RPM's, which is the rev limiter

2006greyGT · March 31st, 2009, 12:21 AM

I believe it goes higher due to the unit of measure... I could be totally wrong but I think I know that from somewhere

SAE adds in barometric pressure, humidity, and 100 degrees. I think if anything, the 100 degrees would lower the numbers.
