Mazda 6, peformance enhancements?

Ghost Strike · Jul 10, 2004

Hi to all,

I have been considering the purchase of a new 6, and just had some questions for the tuners out there. What kind of HP total can I expect out of the V6 with an aftermarket intake, headers, and exhaust. What's the likelyhood of turbo or supercharger kits in the near future from some of the aftermarket guys? Is there anybody out there thats done some tuning, and had dyno's done for comparison? I'd be very interested in hearing about your mods, recommendations etc. Is 300 horse completely out of the question? 275 might satisfy my lust, but I would think 250 no problem with an intake, headers, and exhaust?

Am I crazy?

Sincerly,

CRS

check out that link for a bunch of website link to performance parts for the 6.

There either is a turbo made for the car or there are a bunch of manufacturers creating one. Greddy is rumored as one of the manufacturers.

As for the headers, intake and exhaust...I would think 240 max outta that,

Whoa, you think only a gain of 20hp for headers, intake and exhaust?! That seems awfully low to me. I have read that the intake alone will give you 22hp, check here:

they show a dyno test on this Injen intake to add an additional 22.1 hp and 24.2ft/lb TQ @5100 RPM and this is for the intake alone!

I had the msds header and Injen on my car and the power increase was there, but I'm not sure if you will get as much as you would like. My dyno can be found on mazda6tech. If you want to reach 250 (bhp) plus then I would add the maf customizer (CP-E) to that list (note the customizer is set up for Injen CAI). To get any higher I would look for a turbo to be made and no 300 bhp should be attainable.

22 hp at the wheels sounds awfully generous for just intake.

Da 6 · Jul 11, 2004

the intake has a customizable maf to tune the pig rich V6 and stop the cels.

Manufacturer's claims to hp gain are under perfect conditions with max power achieved. If we all used these numbers (20hp for intake, 30 for exhaust, etc.) we'd all me driving around with 400hp.

Realistically you only see a 3-8hp gain with a CAI.....
The 22hp that manufacturer claims is the very max that could ever be gained by adding the intake, but it's not a realistic benchmark.

I don't believe it! No way a manufacturer would use optimal-conditions numbers in their sales literature. That would be misleading, and thus that would be morally right.

Thanks for the laugh kain! That was too good.

Kain · Jul 11, 2004

I meant to say that wouldn't be morally right, but you got what I meant...

I'd like to see five Mazda6s with nothing but that intake from different parts of North America (put one in Death Valley, the other in Denver, Colorado) and let's see them rip 22 extra HP on the dyno. I will trade my Spec V right now for a 6s if that happens.

crossbow · Jul 11, 2004

There ya go Kain. Add 20 WHP for the MTX's.

Jenna · Jul 11, 2004

There's pretty much no way they did that with stricltly the intake, they would have had to reprogram the ecm to compensate for the intake. It would have to put out close to 30hp at the flywheel to make that much hp at teh wheels,

30hp from a cai and no computer mods? Where do I get one.

TheJohnny · Jul 11, 2004

Holy Cow, at Adventon, INJEN intake for the 6s is $17?.00... plus $15.00 for shipping. That's insane.

Kain · Jul 11, 2004

Thanks for the dyno sheet, but I never just add or subtract numbers to factor in different variables. Let's see just that intake on a manny tranny with the conditions I laid above (lowest altitude in the U.S., highest altitude in the U.S.) so I can be convinced.

crossbow · Jul 12, 2004

Kain,

Well in 8-10 dyno's, the MTX's statistically dyno 15-20 more WHP then the ATX's stock. So ya of course you shouldn't just add...but its a safe bet to say that the CPE/Injen will be pushing 200 WHP on a 6s MTX.

Jenna,

The 6s is crippled by a very very very rich A/F mixture. It actually gets BELOW 10:1 stock in the upper rpm's. All the intakes on the market lean out the AF (by using odd sized tube diameters) and by moving the maf higher up in the pipe.

This is generally how most companies get gains, as when you run a stock diameter pipe, their usually really low. (K&N dyno's about 5 extra peak hp, and 7 max).

The dyno's above are stock vs the Injen Intake/CP-E Customizer, which isn't a piggy back persay, just a device which adjusts the maf signal back to stock specifications, allowing you to run a ginourmous intake pipe without throwing check engine lights, or having irratic idles.

The CP-E also smooths out the transistion of the A/F curve (since it can control the max signal), and does some A/F tuning in the upper rpm's. (Reducing the amount of carbon deposits the car throws out stock).

The stock car runs so rich, that the cat's are getting flooded with fuel, and its igniting, raising exhaust temps, and probably requiring that we all replace our cats before the warranty is up =/.

CP-E is currently working on their own intake with a "programmable" maf customizer, which were TRYING to get the 3.5 Diameter pipe to fit...cause it looks hella cool, and because we can.

We will have to fiddle with the battery tray, possibly making a new one, or modifying the old one to push the stock battery further back. You could just run an optima and have enough clearance, but most people don't want to have to buy a new battery just to use an intake.

Basically pushing the battery back would not only allow for a larger pipe to be run, but a STRAIGHT pipe to be run direct to the wheel well, without having to have two 90 degree bends.

Two questions:

1) What is the purpose of them having a a/f that rich? Wouldn't it make emmissions worse?

2) I thought I remembered seeing a dyno on one of the boards where just putting in a K&N panel filter added something like 4.2 HP? Anyone remember seeing this?

1) if tuned corectly it would outrun the RX-8 plus there are alot of other things too question like crush bent headers, restrictive intake mani, and egr warming 3 of the 6 intake ports.
2) the Resonator delete yielded a bigger gain than running no filter at all.

Necessity · Jul 12, 2004

Another note is that the gains arn't stacking.
ie:
headers + 12
intake + 17
exhasust +5
Dyno's are showing that this doesn't add up to +34

Now with the CPE gains, I'm thinking it was a huge mistake to get the v6...

crossbow · Jul 12, 2004

The AF ratio is so rich, because the main cats have to last 120,000 miles now =/.
