Kinetix 370Z/G37 Velocity Upper Intake Manifolds - Z1 Motorsports
 

Hello everyone,
As many of you have seen, both in person and in pictures here on the370Z.com, we currently have a one of the new prototype Kinetix Velocity Upper Intake Manifolds installed on our project Z1 370Z.

After much praise, discussion and inquiry about the plenum, we are strongly considering the possibility of offering the plenum for sale on our website. We are currently waiting on making the intial purchase in order to gauge the general interest of everyone on here and their listen to their opinions.

At the moment, the plenums are priced around $1050 plus shipping.

Some of the benefits of these plenums, aside from the overall asthetic gains over the plastic upper intake manifold, will be the plenums strength and durability when exposed to the added stresses/ heat of turbocharging/supercharging. The highly polished plenum works with all factory hardware, sensors, intake, etc with the exception to the factory engine covers (..but why would you want to cover this beautiful looking plenum anyway?!)

Exact gains in horsepower are uncertain at this time due to the fact Kinetix is performing some further revisions. So look for an update soon!

If you have any questions whatsoever, feel free to post them below or shoot me a PM.

Group Buy!!!!

In for more updates.

:tup: I want! :driving:

In for updates.

definitely need a group buy

If the gains are there (even after already doing the other bolt-ons), I'd definitely be interested! It looks gorgeous.

personally, I think the pricing should be around $750 at the MOST for it to be worthwhile.

GB yes please. At current pricing...eh, thanks, but i'll pass.

Looks so cool, but i wouldn't want to put that in with my FI setup when the FI kit has not been designed to work with the manifold.

Just re-tune it. But I think it will help with heat and separation issues down the road.

Looks perfect for an N/A setup, wonder how much this will help...

995 is a bit pricey probably closer to 699 750 with atleast 10whp gain is fair. looks nice though.

looks great. Im in. ill buy it

u read my mind =]

I'll wait on the power gains to surface until I make a decision.

While I don't know the gains and am unsure on the price I know for a fact that this is something I would want before I shove 10 psi down my engine's throat.

True. But with forced induction it will be a while before the numbers on a FIed car comes out.

why are we assuming that this will give any gains?

By reading the description, it only mentions "durabilty, looks, etc", not larger volume inside the manifold to show possible gains..

it will be about two weeks max for kinetix to have there results. ITs been tested for gains and etc

I'm personally not riding on the gains as much as the increased durability when boosting the car.

Being optimistic. We sure as hell dont want to lose a ton of hp. I am considering it cause I will be boosted soon and there is a sure need for it at that point in manys eyes.

im in if the gains are decent

I'm all for this as a show piece and all as I had the original and I would buy this thing just because of the metallic growl it made...but why are those who are looking to go boosted or boosted looking at this thing like it's a safety piece? Doesn't GTM practically have a 1000 Crank HP big bored G37 still using the stock manifold?

saftey of mind

Because the stock mani. is only rated at 4.5psi, this info comes from stillen which came from Nissan.

Damn, that looks bad a$$!

Will there be a black finish option? Cost?

Must not have been good results, and thats why they didnt post them and are making slight modifications. All looks and no gains it seems. But I will wait and see but would not spend that much for engine bling bling.

If Z1 sells them and you want a black finish, I'm sure it will be available at a reasonable cost. They have a great powdercoater :tup:

there will be gains. Just waiting for final results.

From looking at it you can see the advantage from fitting this with an FI kit and getting a tune specifically for it.
GB for sure, 1K not too bad for a custom intake manifold, but at sub 1K it would be a lot more interesting, lets see the untuned and tuned dyno sheets on the Z in stock and bolt on format.
Does Kintex plan to produce a thermal spacer to sit under it? that would be a nice and cheap extra touch.
Looks a perfect piece for 6 individual meth nozzles also .. slurp

Black option for me if they do it.

I still don't buy that. If you research the material used to make the factory manifold (manufactured by Dupont) it is also used in plenty of other manufactures forced induction cars.

That isn't to say that there won't be a benefit of an intake manifold change for forced induction cars, but i don't think 4.5 psi is going to cause the stock intake manifold to explode. Otherwise GTM, GReddy, and AAM would all have some issues with their respective turbo kits.

BUMP FOR UPDATES FROM Z1 lol!

When asked about torque gains.

"Minimal on our test car (2009 370Z) honestly the power gains on an NA application are not there. We are working with Kinetix on a revised runner length and design to see if anything more can be gained. We hope to know more once we're able to test on an HR 350Z."

"We tuned it in house with Osiris, but as I stated earlier the NA power gains were minimal, not a lot of use in posting dyno charts that don't really show any thing of value at this point. Keep in mind that the unit on our 370Z is a prototype that we bought from Kinetix for testing purposes before making a large investment in a stock order."

Posted from Z1 on the 350Z forums, hopefully they will take Z1's advice on runner length and what not, but this may go the route of the first one. Hopefully Kinetix takes Z1's input instead of just mass producing as is otherwise this will just be another (very pretty, great sounding) engine bling item.

I would agree that it can take more than that if I remember Christian with his TT G37 now has about 10-15k boosted miles on his car running anywhere from 6-8psi with no plenum damage.

Though the SS manifold is pretty and sounds great it also cooled a lot faster than the old cast manifold on my 350z, though the new plastic composite manifolds on the 35HR and 37VHR may have already taken care of that piece as well.

Really? who?? :rofl2:

I think this would look badass with the "tanks" powdered to your choice, while leaving the runners polished :tup:

So after reading the whole thread it looks like this will add little to no advantage to an N/A setup. It won't work with the stillen supercharger because that uses a custom manifold.

I don't see how it would really benefit you if you used the GTM S/C or TT setup. Frankly the limiting factor will be the pistons and rods, remember we're already running 11:1 compression (I might be wrong but not by much).

If it was me I'd wait till I built the rest of the block before I added this piece, the plastic plenum looks like sh!t but I've been told by Vinny Ten Racing on LI who knows Z's that it's pretty reliable and durable.

Unless it was designed with a flow bench its unlikely to do much more than look shiny and add weight...

Other than that, runner length will just move peak torque either up (shorter) or down (longer) in the RPM range. Bigger diameter may or may not help N/A -- again these things should really be designed with a flow bench.
