Woods1 Posted April 21, 2013 Share Posted April 21, 2013 Hi guys just a feeler thread- I've been looking into intake manifolds since I bought the zed and I'd love a kinetic plenum as they seem off reviews to give good gains but there also the thick end of £800 quid and seem to all come from the states. I'm going to be fabbing up the plenum aften I've finished the inventor 3d model and get it dyno'ed to give before and after results. The main question is, is this something that other zed owners would be intrested in? A proven intake plenum, made well with all the supporting calculations and proven dyno results around the £500 or below mark? If my example works out well I may start to manufacture these in small batches and wonder if others may be as intrested as I am in unlocking more gains than a spacer can give?

KC350Z Posted April 22, 2013 Share Posted April 22, 2013 sounds good keep us updated on results and prices Quote Link to comment Share on other sites More sharing options...
Keyser Posted April 22, 2013 Share Posted April 22, 2013 Be intrested to see if you got good gains on an SC'd Zed, in which case I may be intrested - the kinetix V1 was known for blowing the welds (here come the F and F quotes) on high boost FI Zeds.

The manifold im doing is for an N/A zed, FI is a different beast and would warrent a different design. If there was enough interest then i will come up with a design and will need a test car, but as the majority of us owners will be N/A il be sorting that out first. I just begrudge paying nearly a grand for an intake when i know i can design and manufacture one for half that. And im surprised to hear that the kinetic ones fail on the welds, that sopunds bad quality and i can stress that anything i do would be fully purged when welding and id pressure test the manifold to assure quality.

RobPhoboS Posted April 22, 2013 Share Posted April 22, 2013 £500-ish and I'm in if the gains are reasonable (which is possible I'm sure) Quote Link to comment Share on other sites More sharing options...
D12BHP Posted April 22, 2013 Share Posted April 22, 2013 I have Kinetix on FI set up no issues! although if your paying near £800 - better off with the cosworth Plenum! Both looks great as well... Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted April 22, 2013 Share Posted April 22, 2013 Just thought I'd mention, a lot of us have the plenum spacer - so would your design work in conjunction with that ? Quote Link to comment Share on other sites More sharing options...

theheff Posted May 18, 2013 Share Posted May 18, 2013 Just thought I'd mention, a lot of us have the plenum spacer - so would your design work in conjunction with that ? He's talking about doing away with the stock plenum and replacing with a different style intake. Your plenum spacer would be redundant This is the kinetix he's talking about 1 Quote Link to comment Share on other sites More sharing options...
Toon Chris Posted May 18, 2013 Share Posted May 18, 2013 (edited) Logically you could swicth that 180 degrees by shortening the intake pipe, then have a more direct - even a bifucating - feed to the plenum. How does this design even out the intake pressure between cylinders? It looks like the air delivery would be uneven, and with such a large plenum area does it suffer from positive or negative pressure? Maybe the Z isn't that fussy and works fine but this sort of design must make a difference to how the throttle behaves.

Mark@Abbey m/s Posted May 18, 2013 Share Posted May 18, 2013 Kinetix doesnt work on a N/A actually loses BHP/Torque we have found. Cosworth only works on N/A when revving higher than 6500+ rpm. 1 Quote Link to comment Share on other sites More sharing options...
SkylineV35 Posted May 18, 2013 Share Posted May 18, 2013 its all just underbonnet bling until you go f.i i heard! but wouldnt mind a cosworth with carbon side bits! Quote Link to comment Share on other sites More sharing options...
