Kinetix Intake? You make up your mind...

[Cattman]

I will emphasize again that we will beat any price - advertised or unadvertised - on the Kinetix intake.

There are different perspectives on the Kinetix intake manifold. We've sold a bunch of these to Maxima and Altima owners (let's not make assumptions based on other cars) and they tell us there's power made on the top end but they either don't make power, or lose a little on the bottom end. Nothing surprising about this, with a single runner design.

We'd be willing to help sponsor a dyno test on a customer's car, under our supervision (in Tucson) so we can make sure everything's done correctly. Its not practical for a vendor to buy an IM and dyno it - we'd have to sell dozens to make our money back, given the very thin profit margin. Otherwise, its up to the buyer to do their due diligence.

I'm interested. I'm also interested in your cattback.

that's what i'm talking about.. when i get my kinetix IM, i'm buying from you brian.. it only makes sense since people are so hesitant about buying this thing without seeing a non-kinetix dyno.. i really believe this will help your business

[Cattman]

I don't want my dyno offer to seem like a hollow promise, but I need to be clear that carrying this out depends on finding a willing Kinetix customer within driving distance of Tucson, or perhaps in Phoenix. However, we don't have that many local customers, so I think we'll be lucky to find a volunteer.

I'll also just toss out that a basic before-and-after dyno comparison of the Kinetix IM will tell part of the story, but this is the sort of part that may require fuel tuning (particularly with this engine/ECU) to maximize its potential. A dyno session will be useful, but I think we need to see some real-life results from a few fuel tuning sessions to have a complete picture of its performance capabilities.

I'll start receiving the next batch of 04-07 catbacks about mid-week, give us a call.

hey brian next time im going to flagstaff ill make it a point to drop down and pay ya a visit either for the dyno w/kinetix or just to thank ya in person for the exhaust im soon to getting

[Sprint™]

Brian.. i removed your section of your post that takes an issue of other Vendors... we have a very close nit community here which you have been apart of longer than I, however lets try to keep things fair among each other.

well at least us consumers have something to look at before we invest that kind of money in a performance part.. thank you for being willing to help out in any way you can.. i, as a potential buyer, greatly appreciate it

Funny!! i dynoed with it over a month ago!!!!!

So where's it at?

[Cattman]

JP's dyno on his 5.5gen turned out quite poorly, with big losses on the bottom end, and little gain on the top, so he took the part back off his car.

I'm baffled by this. If I had 2 or 3 other customers telling me this, I'd probably drop the part like a hot rock, but JP's experience contrasts dramatically with other customers that have seen measureable and consistent improvements in their race results. These are guys that race once or twice a week - 1/4 mile, autocross, open track - and they're very in touch with their cars. I'm not saying this to contrast them with JP (his racing pedigree is very solid and I don't question his judgement in any way), just to point out that they're not imagining the IM performance on their cars.

So, we've got several customers that are very pleased (or at least they were when they spoke with me), several we've gotten no feedback from, and one customer who is definitely not satisfied. This mix of experiences is part of the reason we're more than willing to take a Kinetix-buying customer down to our local dyno shop and supervise the before and after runs, I'd really like to prove this to myself and have some data I can personally stand behind.

wow that intake manifold looks beastly

bump for a great guy to deal with.

snolife - haha nice sig picture.

Were you tuned when you dyno'd?

untuned!!

[ShIft_uR FacE]

well there you go. im sure you wouldve seen gains if you had tuned it.

[Jay_pee99]

I dynoed both ways, One for Cattmans notes, and tuned for me!

[ShIft_uR FacE]

and both dynos (untuned & tuned) proved the same results?

[Jay_pee99]

tuned it was running way rich around 4.6krpm. After tuning and tweaking in other spot i gained somewhere around 10whp, But was still 1hp less than stock manifold without a tune and over 20wtq less than stock. I dont have the exact numbers in front of me so dont quote me on this yet.

[Jeff92se]

That makes sense about the rich thing. Every power mod that's proven to make hp, causes the car to run lean. That means the mod promotes more airflow. since this thing caused the untuned motor to run rich, it would appear it caused a LOSS of airflow.


Brian, I watch the Z and G forums fairly close. Honestly I haven't come across more than 1 or 2 guys even commenting on any sort of power gain. Much less offering any type of dyno referenced proof.

I HAVE come across guys that are happy with the mod. I imagine for the bling factor. One guy knew it wasn't a power adder but had the thing for show purposes.

So no tune=no go?

...Not always.

A mod that improves airflow can easily cause the engine to run rich. Depending on the mod, the increased flow without corresponding changes in IAT can cause the ECU to think it's seeing something unusual and richen the mixture to compensate.

So, on that untuned engine with the Kinetix IM, the ECU might just have been overcompensating.

As with any significant breathing mod, every car might respond differently. So, you definitely should do a tune with it.

[nismology]

To me, if you need to "tune" to see ANY benefit from a product it isn't worth the time or money. A/f changes on their own don't really affect power a whole lot in the n/a arena anyway. Ignition timing is where real power is made.
