If you think an intake is going to magically make up for a considerable performance difference, please let me know what you're smoking so I can get some. Unless the 3.0L Duratec engine in the Mazda 6s is dyno'ing 210whp even after the intake mods, it's not coming close to a stock VQ series Altima engine.



The intake svtcarboy is referring to is not just an intake. It's also a piggyback that alters your A/F ratios (known as a "MAF Customizer") to produce significant amounts of power. And yes, it does dyno at 200whp -- an increase of 22whp over stock. Not Peak Gain. Gain across the entire curve. And this has been dyno'd multiple times.

We all know that the 3.0L Duratec has a lot of potential, and one of the biggest areas of gain is the piss-poor A/F ratio.

I can't link to the Image, but if you go to HERE and scroll down to the Dyno for "6s MTX HP vs Stock" under the heading "What Gains does the CP-E Intake Give?". Make sure you're not looking at the dyno for the Injen+Customizer.

The intake came out too late in the year for people to go to a track to get track times. But seeing as how I could run a 14.7 with just an Injen that was only doing an average of 7whp across the powerband, I can imagine the CP-E will easily push the Mazda6 into 14.4 territory.

As for mods, you can't really make that argument because when you add the same mod to the VQ series, you get just as good of a result.



Of course anyone will agree with that statement. The argument is that you can save yourself $4000 by buying the Mazda6 -- more than that if you're talking about an SE-R. You can use a small fraction of that money and bring yourself up to the Altima in terms of power.

And, no, that's not the same argument as "I can put a turbo in my Neon and outrun a Corvette and save $25,000" because those cars aren't comparable. The Altima and Mazda6 are, aside from power otherwise very comparable cars (to most people, there are numerous other reasons why I wouldn't buy the Altima).
