Kinetix 370Z Intake Plenum! Should i Buy it ?

Zedx

oK guys. Looks like Kinetix has come out with a prototype for sale over at Z1 Motorsports.
Take a look. below


Should i get this ?

Kinetix Racing has recently developed a new aftermarket intake plenum for the 370Z. This is a prototype plenum and is not being sold as a performance product. However, we have seen gains on forced induction applications.

Looks fancy LOL I will be watching for this thread for updates. I would like to see if anybody buys it and gets us some numbers on the board.

V8Killer

Whoa 750 bucks for possible hp gains on F/I? No reports of N/A? What kind of crap is that?

Zedx

yeah. not much info. but seeing how i am stuck at 309HP on the mustang dyno. I really want a intake manifold. Just need more info. the motordyne one doesnt seem to do anything time and time again. or maybe our intake manifold truly is perfect? nah....

Hmm 309 only? I plan to pass those numbers in a couple months with F.I. CBE,LTH, Stillen UD pulley, G3 intake. You can try the intake manifold be my guest and if it works out then I'll jump on the band wagon I hope you reach your goal. What are you trapping at the track?

Motordyne

Hi Zedx,

Have you seen the dyno plots posted at the beginning of this thread?
The Motordyne M370 Intake Manifold

Basically every independent dyno plot that has been posted in this forum has been copy/pasted into the first post of this thread. It contains the pre/post plots of 11 different vehicles. One plot shows a loss of power in the last 500 RPM of the power curve but also shows much more significant gains in the rest of the power curve. The other 10 plots show a broad band gain in power and torque gains in the upper midrange and approximately break even at the top end. +/- 3-4 HP tolerance range.

If it were possible to create an average of all the 11 independent dyno plots, it would show the M370 is making clear gains over the entire RPM spectrum with ~the same peak power.

Zedx

Is there a new version coming out?

NO you should not get. All it is is a polished terd. No better than the one they made from the 350Z days. I had one on my 350 and it was on a FI application and netted me no numbers. I removed it a month later and bought a Crawford plenum and gained numbers. Proof is right below. Mainfolds/plenums just dont benefit much at all if any on are type of motor (37 VHR). Buy you some long tube headers instead.


BEFORE (This is with a Turbonetics kit on a 3.5 non revup motor)

Crawford Plenum? Do you mind directing me to that location? I ordered some F.I. LTH already, in your opinion you think I should throw that extra buck for what you got?

Mike

Crawford plenum was for the 350z, Doug doesn't make anything for the 370z

K cool thanks for the heads up Mike.

Zedx

Yeah i hear you on the long tube headers. BUT the goal is to keep the car street legal. So i run High Flow Cats. Not to sure if shorty stillen headers will gain anything. mmmm. Yeah. thinking probably not goint to go with this. Been looking at our stock manifold and its damn near perfect. Hope a good one does come out at some point though. Come on Cosworth!!!

I've been debating on swapping intake manifolds, but I know very little about them on the z. I've done some searching on here, but is the Motordyne pretty much the only option for us as of now?

SPOHN

I would just stay away from any manifold. Not knocking anyone. Just there is more benefit to be had with a single or combination of intake, TP/ HFC, exhaust and tune.
