I got my MS3 Dynoed today, it has the CPE CAI on it and nothing else. They did two runs for $40 at The Dyno Shop in Santee, CA. Anyway it was pretty sweet, never been before and it was a good experience. Unfortunately mostly muscle cars showed up today, not many Japanese cars, two more Speed3's were suposed to show but I waited around until like 11:30 and they didn't show. The numbers for my self was: 228.61 HP and 242.8 Ft/Lbs of Torque. Pretty sweet, everyone there was pretty impressed as well as the guy who drove it during the Dyno. He said it was really smooth the whole time. They only thing they said was that it runs really rich after 4,600 RPM's and Mazda does that to keep things cool for safety. And it was a tiny bit lean from 2,000-3,700 RPMs So for the best gas milage shift at 3,500 RPM's and most power shift at 5,600 RPMS, thats where I hit my max HP. Anyway, I'll be interested in the other MS3's that may have shown up, one has a Mazda CAI and the other is stock I think. There results should be on this web page. http://www.dynoperformance.com/dynoday.php Just scroll to the bottom and I'm assuming it will be under the Mazda link, I'm under gotnospice, the other two Ferdball (Mazda CAI), and ZooZoom (Stock I think). These are all contrasty so you can see them better.

Numbers seem a little low for having a CAI. I guess its just because there have been so many recent posts with bone stock numbers being in the 250-265whp range and 270-280wtq range. Its funny how much variation we're seeing with these cars in terms of how much power they're putting down.

The cars are all within ~2% of each other in output, it's the dyno's that are providing the variation.

:shock:

2% that :lol:

I'm a little disappointed in my run. There were a few click sounds during the first pull. The tester backed off, so I only got one good run. There was no CEL, and nothing seemed unusual after the run, but that sound has me a little concerned.

They use this clamp on some wires. Does anyone know what they clamp on to? And if that clamp is grounded, could that cause a short? I don't know, but it was really wierd. Nobody had an explaination.

Anyway, here's ZooZooms sheet.

I keep saying that this car would not be a sub-6 to 60mph if such low hps ratings and weighting more than 3,100 pounds. This car is easily 250 whp. The more dyno results I read the less and less I believe in dynos. It's not even within 2%. 2% on 250+/- is 5 hps if nobody has done the math. Your dyno is way off. This car does the 1/4 mile at 100mph+/- in 14 secs+/-. If you can do that with a weight to power ratio of 13.7 (3,150/229) in a FWD vehicle, you are doing magic. Specially considering the torque limited in 1rst and 2nd.

Well, this should be a really good comparison, because you've got the same dyno on the same day. Heck, we each had the same color, CosmicBlue. But we've got wildly different results.

Stock - 240 Horsepower, 249 Torque
CPE-CAI - 228 Horsepower, 243 Torque
MS-CAI - 235 Horsepower, 251 Torque

The stock car has a higher peak horsepower. Everything else is so different, its hard to even begin to compare.

Going back to what I said before. How in the world can you get less hps with the CAI than stock? This is another proof that dynos are almost worthless. I could feel the difference after I installed the CAI, and believe increase in hp that are less than 10% are difficult to discern. I and many others immediately notice the increase in power. Your car was heat soaked or something went very wrong with the dyno setup. It's unreal.

peak hp might be diffrent. but the big diffrence you need to look at is the curve.
so one car has more peak. but the car with teh better curve can use there power and get up to speed sooner.

also the clamp. shoul be for timing. every time the plaug sparks it tells the computer its doing so!thats how computer gets rpm. the plug fires once ever other revolution. so thats where it gets the rpm opr tach on the screen.

The variables in dyno's are immense. They're really only good for baselines and then measuring increases. So if you think there's a problem, it's very difficult to use a dyno as evidence of that. Sounds like it's time to take it to the dealer, though don't mention dyno, but more your butt dyno.

Ah. So there wouldn't be a risk if the clamp were touching anything else?

Thats just it. The butt dyno shows an increase. I can get the front wheels loose in the top of second gear, and sometimes in third gear. Couldn't do that before the intake. It definitely has more power.

if those stock ratings are from mazda, they are probably from the engine... not the wheels. that might explain the higher hp.

What gear was used for the dyno?

I believe it was 4th gear, but I'm not certain. ZooZoom's was done in 4th.

man there's a lot of "ass talking" goin on here. all 3 of us dyno'd on the same dyno on the same day. it doesn't get much better than that. sure the temp can vary a few degrees during the day and that might have a 1 to 2% effect here.

I'm not sure why my MS3 had the highest hp rating. I do drive my MS3 aggressively so the ECU has "learned" to optimize performance. I drove the car about 50 miles non-stop to get to the dyno shop. I was enjoying the highway and made sure to vary my speed frequently (traffic helped that out).

the only "mod" to stock that I have other than bling stuff like LEDs/HIDs, motor mount, shifter bushings - none of that matters of course - is that I removed the cover on the inlet tube feeding the stock airbox. I also removed that plug on the small grill opening. its not at all unreasonable to believe that the stock airbox feeds it pretty well. you know the engineers do actually calculate this kind of stuff.

Ferd definately had some tuning thing going on. his engine was pinging quite loud during his first pull. its very possible the ECU was pulling timing. I don't mean to fan the flames of doubt about the CAIs but you can't agrue your way out of these dyno results.

Pinging would explain the low run. I've never heard detonation that loud before, but then I've never had the hood up. To me, it sounded more like an arc.

Yeah I wish I was there when you guys where. I mean I don't get the numbers though, they don't make much sense. I think that the stock intake can't really pull even close to as much air as a CAI, just doesn't make sense. I'm stumped, not really sure. One thing I do know is that my car feels much different after the CAI, like Ferd said can spin the tires in 2nd and third. We should all meet up, fine a long empty road, get up to about 40 mph and then all punch it at once, see if anyone pull a ton more then others? Don't know how else to test it then real world.?

a red car would give better results. everyone knows red cars are faster.
