Here are the results I could not get a base line before but I had all active mods filter pulley xpipe and muffler with there tune. And Active has dynoed countless s65 's so we used an average (sorry if that is not good enough for u die hard dyno fans). It made consistant 370ish to high 376 on a 91 degree 51% humidity. the other run was a pure stock car.

Well considering M3's seem to vary in power up to 30hp between different engines... Without a base dyno to see what YOUR car actually does its basically useless for seeing what a modification actually does.

You can call it what it is there would still be to many different variables even if I had a base line due to weather and time a day that could make a 30 hp difference. We can argue over dynos any day what's the point, some of u guys think the stock headers and x pipe are perfect and make the best power I have yet to see any m3 na making over 370 on a mustang dyno. With full bolt ons

I am considering the American Racing headers for my e92. I am just hesitant until I see a FBO vs a FBO ARH car so I can quantify if the gains are worth it.

If you are going to rule out all dynos with 30 rwhp gains then you just ruled out almost every bolt on dyno of every n/a mod made by every company for these cars. I know a hardcore small group is out to trash ARH, but that is going too far in my opinion.

+1
same here! I don't think we'll ever see a N/A dyno comparison.

My problem with your chart is a FBO car made 346 vs a stock car at 329. That's only a 17whp gain when the standard gain is usually almost double that. So I would agree there is some truth in stating that without an actual baseline, it is not conclusive to advertise ARH gains in this case.

Bias seems to be overwhelming...the product has been out for maybe 6 weeks, and statements like "we'll never see N/A dyno comparisons" are made with such certainty.

If you're referring to my reply, your contents in your quoted statement is not correct. Me saying..."I don't think we'll ever see a N/A dyno comparison." is very different and incorrect to what you put up....which is "we'll never see N/A dyno comparisons" If you're going to quote someone it has to be exact in wording..that is what quotations are.

it's been longer than 6 weeks. Bias?...no ...I'm actually hoping that it make the claimed HP boasted....so bias...no, not me.

So as the dyno chart shows, these are three different cars...correct?

There's about a 9% difference between Mustang and Dynojet dyno's. Your 370 on the Mustang would be about 403 on the Dynojet. Here's the highest FBO Dynojet entry in the Dyno Database: 403whp, FBO, stock headers, 91 octane, 6MT. On average, 6MT performs about 7whp lower than DCT, and 91 Octane performs about 12whp lower than 93 octane.

http://www.s65dynos.com/showDyno.php?recID=666

Were you 6MT or DCT? In Florida, I assume you were running 93 octane, correct?

Weather matters for uncorrected horsepower; weather matters little (or should matter little) for SAE corrected horsepower. Most dyno shops show you either SAE or STD corrected horsepower, usually they never show you uncorrected horsepower. Do you know which correction factor they ran (SAE vs. STD) or were these uncorrected results?

Maybe more like 12 weeks...not even counting the few installations before this one.

Here's my proposal:
Nick offers a money back guarantee. I say it's time to put it to the test.

We'll hit the dyno, and I'll data log your car with everything I've got...including CAN bus datalogging.
You buy the headers, drive it around a few weeks, and we do it again.
Get it "custom tuned" then drive around a few more weeks, and we'll do it again.

If they don't perform to your satisfaction, then ask for your money back.

I'm free all summer!

silly whether it was out 4 months or whether the actual quote really "I don't think we'll ever see a N/A dyno comparison" is a nonetheless strong assertion and doesn't detract from my point. We'll see if the confidence is misplaced or not. (boldface is mine, as you technically did not boldface it to be clear to everyone). As I write it looks like it is going to happen.
