mazdaspeed3 cai?

[Speedy3]

Had a much better, more consistent run today with dry pavement. Check my most recent post on the third to last entry here:

http://www.mazdas247.com/forum/showt...3662057&page=5

My most recent test runs resulted in a 34.5 HP and 30.1 ft-lbs torque gain with the MazdaSpeed CAI.

Speedy, I responded to your gains in this thread:

Those are impressive numbers, for sure, but I think you should be investigating exactly where the gains are coming from- mainly, is your intake leaning out the air/fuel ratio? If so, it may create problems down the road once you inevitably do some ECU tuning (unless you want to pay for a custom tune and dyno time).

Not trying to beat a dead horse here...but I just talked to Mazda again and they stated very solidly that the Mazdaspeed 3 CAI and CAT back exhaust combination adds 35 HP and 30 ft-lbs of torque. They have done the dyno and confirmed the numbers. They did not dyno the CAI alone, but clearly, I don't think it would add 25 HP by itself. (As I have read elsewhere.) In any event, at least we have some data now from Mazda that gives us some solid numbers. I even found this on a drivingsports.com:

Oh yeah...they wanted $1400 for the all the parts and $450 for installation...

Their prices quote is still jacked up too high. Also, if they are not willing OR able to show the dyno plots they made, their info is not that credible.

Agreed. Well, I made my dyno appointment for this Saturday. I should have the MS CAI with MS Cat-back dyno results ready for Monday. (I may have to just give you the numbers --- I don't have a scanner for the dyno print out.)

We will let the data speak for itself.

They most likely can email the image to you. That's what the Dyno shop did for me.

I will certainly ask.

If it's a dyno jet you can just get the runs from them and run them in the viewer on dynojets website. From there you can do a ctrl Print screen and post the jpg after copying it into paint or photoshop.

I will ask about that as well...

Thanks!

Picked up the Mazdaspeed CAI for the MS3 today. Trying to make time for before and after dyno runs next week.

Dang, I want to put it in the car now!

Post your results here:

My new install appt. is Thursday for the MS CAI and MS CAT back. The mechanic told me not to expect much gain from the CAT back. (I wish I knew that earlier.) He told me it would give me about 5-7 more HP. This is actually consistent now with other CAI dynos and posts. (25 HP from the CAI, and about 5 from the CAT back.) Clearly the cost / performance factor is massively in favor of the CAI. Oh-well, too late now, I ordered both.

Dyno is still this Saturday.

 

[Bakrauf]

Ye that does sound about right. So would $500 be worth the Cat back? Thats why Mazda said Both will add gains of 30-35 hp. Who would buy a catback for 5 hp?

 

[camrycev6]

I say once we have that proven here once and for all, not many. Again, I will know very soon. Clearly, the CAT back is essentially a "looks" only upgrade --- something I am steadfastly against. I guess my lack of patience got the best of me.

don't forget about the sound,
speedy3 what are your air fuel ratios with that intake on.

I haven't gotten the A/F ratios with the MS CAI yet, but will soon. Although not as helpful, I did record live data on the second dyno in the stock configuration. I just didn't bring my laptop on the MS CAI dyno (kicks self in ass). I will do some 3rd gear runs out on the street after I re-install the MS CAI and get the ratios.

What was the differnce in the Intake air temp?

what kind of device are you using when you do your runs, I might get one.

Both Speedy and I have Auterra DynoScan units. It requires a laptop to run. I can't reccomend it for it's Dyno feature for the MS3 though. Apparently we have discovered the RPM output from the MS3 ECU is not smooth through it's range which makes for some really weird HP/Torque plots. It does work great for real-time readouts of all kinds of interesting parameters, as well as reading and resetting codes and other stuff.
