what?

 

I'm willing to be the guinea pig if Kinetix will give me an intake. I'll bring my tuned Vortech (just dyno'd last month--372 HP/305 T on an otherwise completely engine/exhaust-stock set up) to a local speed shop for baseline dyno'ing, installation, redyno'ing and re-tuning. I'll then post the results for all to see. This will be a real-world, objective test of the new intake on a standard, 8 lb Vortech system. My first tune via Dynapak 1 month ago was almost perfect with an out-of-the-box Vortech setup and, after mild leaning out during the fine-tuning, ranges around 11.5 AFR under good boost (3-4 lbs plus) up to redline. I'll arrange this with XX Tuning in Hartford, CT. Is this do-able, Kinetix?

 

I still dont understand how people are making 370 hp and only 305 tq ...
Im making 360/ 330 ..
Hmm weird ..

 

royce so & valdeztke...

if you would note, I said based on R&D and appearance, not just appearance. If you bother to read more than just this single thread about the Kinetix intake, there is a lot more information to be had regarding its development.

I'll address the part you noticed first, even though it is by far the lesser of the two factors I was highlighting... look at the runner design. It is very direct compared to the stock design. Fewer changes in direction mean better air flow.

In regard to R&D, in the long thread (if you take time to read it) there were several comments made by Kinetix and SungNam both mentioning aspects of the design process for this IM. The runners were designed to be equal length and deliver equal air to all cylinders. The square-ish box on top is not necessarily optimal for this in NA application, but for FI where you are filling it with pressurized air, this does not come into play as much.

This compared to the stock setup (with or without an aftermarket upper plenum) in which the air shoots in from the back (as it does with the new Kinetix Plenum), but then moves from the middle of the plenum outward towards the sides, must redirect down to the runner inlets, then redirect again to follow the runners. (If you've ever had your stock plenum off the car, this is pretty easy to see) In simple terms, the Kinetix IM cuts out two changes in direction of air flow. Air still shoots in from the back, but only must make one turn to enter the runners. Less turbulance... better flow... more efficient power. Not to mention, in the stock situation, even under pressure, I'm not so sure the runners are giving equal air flow. Though I don't have info on that very last point to say whether I'm correct or not.

 

Finding someone in Albuquerque that had/has R4 knowledge is few and far between. I had the first Vortech SC on a "Z" in the state. Altitude (5200 ft.) was and does remain a problem. Even had to go back to Vortech to get smaller washers for the FMU.

If you back and look where I started this thread or a few posts in you will probably find a graph that showed V4/IM and A/F on one graph. Both stayed stacked until 5600 rpms, then the IM showed some leaning effect. At 5800 it was at 11.5:1. At 6000 rpms it was at 11.4:1. Then started leaning until it was 11.7:1 at 6700 rpms, while V4 was 10.8:1 at 6700 rpms.

Trying to set up a tuning/dyno session prior to the end of week with Polished IM.

 

That is the plan, but you know how things go!

 

i've got nothing against this intake manifold, it's just that i'm amazed no one cares about the specs that are actually going to determine the power increase. does anyone know the plenum volume, plenum taper, runner length, runner cross sectional area, runner taper, whether the runner inlets are radiused, the radius to throat diameter ratio? how many cfm does each runner flow, what's the port velocity, what's the cylinder to cylinder variance, what are the primary and secondary helmholtz resonances? would anyone buy a computer without knowing the processor speed, or the amount or ram, or the hard drive size? should we just assume it's good just because intel did their r&d?

you still have to be skeptical of a 15% hp increase just by slapping on a plenum, especially since the stock one has been proven to be pretty damn good (the rubios made 1200rwhp on the stock intake manifold). remember when sp engineering dynoed an extra 175rwhp on their supra by supposedly just bolting on the veilside intake manifold? as for r&d, gimme a break, the thing is a just box with 6 bent pipes. this design is in most 4cyl. and i-6 cars in production today. what is there to research, if you know how to build a manifold, you can just go out and build it. in fact i've got a manifold sitting right here that i guarantee will outflow that one by a country mile and we didn't do one ounce of r&d on it. i hope kinetix sells a ton of these and makes a fortune, but as of know everyone's assuming so much based just on looks.

 

Nice mailbox...

However, I don't think anyone cares about the specs, as long as there are dyno sheets, price numbers, reviews, and pictures, the general public that is into modding doesn't care about runner length or what it did on the flow bench.

Sure, the stock plenum is fine, but if you are pushing the limits of your turbo(s) and would rather do some engine mods instead of swapping the turbo's, this would be a good route for some extra HP without harm to the engine (as long as you tune after it).

 

You've got 2 mods that I don't: NISMO exhaust and 9 lb pulley. I've got a stock setup for my Vortech. My torque curve, incidentally is close to flat all the way to redline.

 

I want to know if the flow between the cylinders is equal. You dont want to be replacing one uneven intake manifold with another.

 

royce... I think there are those of us that do care about these specs, in fact someone even asked about them over on the longer thread. But, I doubt Kinetix would reveal most of these details, at least initially. This is exactly what they spent the past 1yr+ developing and those specs are what make their plenum what it is. Why would they give away what they have spent so much time developing?

I said it before and I'll say it again... if you're one who would buy this ***just*** for the power gains, you should wait until several people get them and have a chance to provide more independent dynos.

I have four reasons for adding this piece to my car... only one of which is possible power gains. and that's a minor one for me. Hell, as long as it doesn't lose power compared to my current setup, my other three reasons are enough still for me to want one.

 

My thoughts exactly!

Come on guys, where is the GB love??? Only a handful of guys have paid for any products. You are getting about $50-70 off of EVERY Kinetix products except the y-pipe!!!

 

okay, quick question can you use the stock injector on my 03 z after installing a ssv kinetix manifold? sorry noob!!!

 

Yes you can use the OEM injectors with this.
