But it says sae on the chart. That means the numbers are corrected, which would make them higher than uncorrected if the weather was warm.

I'm not saying the numbers are good, bad, average, or anything else. I just don't understand why we so often read about a bunch of reasons why they are actually way higher than what it says on the paper. If the hp should really be 350, then get a dyno making 350 and post that. Or in this case, it's a Dynojet which means you can load the file and print it uncorrected if you want.

Honestly Matt.. I can give a **** less what the numbers say I wasn't done with car what so ever lol. Which I told him..... which is why I asked for the uncorrected. I did talk to the kid and shop and they did say he made more power. So wether it be true or not depends on them....

"If this is "Miami weather" and you posted the corrected hp numbers, wouldn't the uncorrected numbers be lower? What value does it say the correction factor is?"
No need to get upset and start cussing. Remember, you said it is ok to ask questions.

It was just a couple simple questions.

Matt.. if I was done with his car and he got that whp id think those were bad numbers lol so its fine. But like frogstofalls dyno, he was done on that setup but was only 23* or 22.5 I beleive. Now he's on 26 and. Same boost.... So I'm hoping he is higher this time with the new tune. He also had a blown clutch to contribute to his dyno :P.

Actually no I wasn't. You seem to think I am actually still conversating or trying to talk about it.I was stating I understand.... Which is why I said if I was done with his car and his numbers were the above is be kinda worried. (I hate the internet for this exact reason) I understand corrected and uncorrected. Correctional factors like temp, altitude, humidity ect.

Ok....
So I started to add some updated graphs/info to the dyno list.
I began at page 7, because that was the last page BYT posted on.
The following member's dyno information has been added:
hhrfreek
Leafydialupking
zfissette (please PM with your mod list in the correct dyno thread format, and I will add it next to your graph).
MikeyG
I will continue to add graphs from page 7 and on when I get some more time. Please bare with me. I will get everyone who has posted eventually. Thanks!

Since frogstofall won't post it I will...
Mods are ,intake, charge pipes, tr8, catless. Dp, e47 and 24lbs with spike of 25 , and a mid aggressive timing tune. Tuned by me.
On a blown clutch
Matt, I am actually confused on the whole correction thing. I have noticed that when sheets say SAE, the numbers always seem lower than when they say STD. It sounds like you're saying it's the other way around?

In the case I was commenting on, the poster said that it was hot and the numbers were corrected so the power was actually higher. I pointed out that the uncorrected numbers would be lower in that case, and then he edited his post to say that is was hot and the numbers were uncorrected. This was wrong, too, because the dyno chart clearly says sae on it which means that the numbers were in fact corrected.
I comment on these things once in a while because people often misunderstand it. Time and time again I see people post a dyno chart that already corrected the power numbers to sae or std conditions, and then they say something like, "and it was 85 degrees, too!" as if the number would have been way higher had they dyno'd on a colder day.

Matt its a tough trade off. Humidity will effect the car either way, and boosted cars without a vac reference boost control (ala a tuned LSJ or turbo car running with the waste gate vac line disconnected) will still work with corrections. And even with vac referenced, yes they make the same manifold pressure no matter the barometric pressure BUT their volumetric flow rate of air will be different (mass flow rate of air will be the same) and that will put them into a different part of the compressor map.

I added jonathan923 (I still need to add your video).
I removed all dyno numbers w/o a graph (I felt bad removing some of the old heads #'s). If you have been removed, and want to be added again, please post a graph & I'll add you back to the list.
Thanks guys! I still have a lot of work ahead of me.
