steve and spider aren't hating, pointing out the facts. Over the years we've seen some pretty crazy #s from this place...which can't be duplicated on another dynojet etc. Yeh I think it says Ap2s dyno 220ish stock while 99.9% dyno shops dyno it at 200-208 stock.
Look...my car made 230rwhp on Church's dynapack. Most people on this forum think that dynapack reads as much as 10% higher. Fine. Let's take 10% and subtract it from my number...that means I made 207rwhp stock. Very close to what you are saying below.

You guys are acting as if I am coming up in here with some bogus numbers. I have always stated that the numbers were produced on a dynapack. So, if I made 246rwhp on a dynapack, at the very least I'd make 224rwhp on a dynojet. What's the big deal? With my mods that is a VERY reasonable number.

nice numbers, but there were a couple people who dyno'ed 235-240 stock on that dyno, Backcracker is the sn that I can remember off hand. I made a reply about it in the jdm forum under the topic "230rwhp" You made power since you have the before and after, but I'm just curious what you would dyno after on a dynojet and what a stock ap1 would put down on shawn's dynopack.

I made 220/156 on a dynojet with aem v1, tp, and no resonator

Thanks for the props bro! Yes, I have heard people dyno that high on his dyno. The common saying is "different dyno, different days, different test conditions, etc.". Regardless of how high a dynapack reads, it can still accurately reflect gains with various parts. So, I dyno'd 230rwhp bone stock on that dyno, and 246rwhp with my current mods. There is no disputing that I am making 16rwhp more with my current mods. Anybody disputing this is a complete idiot.

Not a hater--just pointing out that there's no way to conclude anything from that run.

Look, my car is still bone stock, so I have no interest in the power game; if you care to spend time and money gettting significant extra power, bully for you. Really. I was just pointing out that it's difficult to reasonably conclude anything from this one dyno. I strongly suspect that the same machine can vary a few HP from one run to the next, and more than that from one day or month to the next.

So the only dyno results that show me that a mod makes a difference would be back-to-back runs, on the same dyno, without and with the mod; same day, etc. One run, especially on a non-standard machine, proves essentially nothing.

I can certainly understand you saying that the runs would need to be back to back to be completely legit. In a perfect world that would happen. Seeing as how we don't live in a perfect world... ...we have to live with the best we can. That said, I've used the same dyno for every run. The test conditions (i.e., temp, humidity, etc.) have been nearly identifical. While it might not be 100% accurate, I'd venture to say it is at least 90% accurate.

The bottom line is that dynopacks are useful for tuning and identifying gains. Any "real" gains should be evident on the track. Given my mods, my S should easily be good for low 13s. Whether or not I am a good enough driver to realize those times remains to be seen.

hit the track and let us know how you do

From experiance with full bolt ons and other people on the boards, N/A is not the way to go for power or 1/4.

I don't have any problem with this. The data suggest that you got some significant gain; it's hard to be convinced whether it's 7%, or more or less, but there was gain. If you think it was worth it, that's all that matters.

True or not, inflated or not, etc., we're arguing over less horses than i have in my backyard. the man isn't saying he's the savior....just give him a thumbs up and move on. good numbers.
I am curious though, is the before plot that you've provided from when you were stock or from when you had all the mods except for the AEM CAI? (or some other combo of mods?)

Concerning the track...I hear ya.

Concerning N/A power not being the way to go...step back and understand that I have an MY06 S2000, and that boost is not an option at this time. Believe me, there is nothing more I want than to be turbocharged.

Until a turbocharger/supercharger is available for an MY06 I am stuck with N/A mods. Please give me some respect.

The lower set of numbers you see is with all my mods minus the AEM CAI.
