Hey guys im new here and dont want to start a war so just let me know if im in the wrong place or if theres some one who did this already. Anyways here it is.... Im looking for someone who has done a similar or the same build to confirm how much rwhp I can expect from my build. I realise the cost of the build isnt worth the power gains but its something I wanna do reguardless i have realistic expectations but a little unsure what the outcome will be. Im starting my first N.A. build on my 04 track edition. Im going with tomei 272 degree cams with 11 mm lift, (springs and retainers of course) Isc longtube headers, kinetex stainless intake, port and polish heads, light weight flywheel, light weight underdrive pulley kit with idler delete and ac delete. Obviously a good tune! Im sure i am forgetting a couple of things. Thats the build i wanna do. I have all of the resources available to do it all myself so there will be no labor costs just parts and alot of time.

 

DE Engine, some aggressive cams, headers, tune, sea level … 291hp

deduct 11hp for the kinetix … 280hp

save yourself the $700 and keep the OEM plenum … Read Conway_160 build thread before you purchase the kinetix.

and update the thread

 

thanks i will check that out for sure

 

I still need to get it on the dyno but 100% N/A i noticed a loss in power down low. But my AFRs arebin the 10's so i may be able to get some power back.

 

Interesting … put the kinetix on and your air:fuel richen'd up … same amount of fuel, less airflow = richer afr … I'm not a fan of the kinetix...

 

A/F ratio can get rich rather than lean because of over compensation, or so I've read. Kinetix said to tune after install. https://my350z.com/forum/intake-exha...intakes-6.html
2bad240 said he gained...was it 4-5 mph (?) in the 1/4 using the Velocity intake and he tested a lot, not to mention he's got the fastest n.a. Z known to man.

 

for sure onevq - a million variables ... to the world: I'm not sold on the kinetix (incase you cant tell!) but I'll listen to anyone that can show me gains.

 

RZG's Facebook has a very recent post of the na 11 sec z. Mods are as follows.
11:1 compression
JWT C8 cams and springs
Obx longtubes
Motordyne Y pipe
3" custom single exhaust
Custom high volume Intake Manifold
Ported Lower intake manifold
3.5" Custom Intake with Velocity Stack
E85
3.9 gears
Z1 Lightweight crank pulley
FIC 550cc Injectors
Fully gutted

I don't see the Velocity.

 

Read the link I provided above. I got schooled about this manifold and he was one of the teachers.

Knowing what I know now about pressure drop, I still do not like the 6 90* bends, those at each runner as they enter the plenum or "chamber" or wehateverthehell it's called, the part of the manifold that has "KINETIX" spelled out. If each runner extends into this "chamber" and has a slight bend towards the direction of air flow I'd feel better about it but if they just terminate, if they're just welded to it, then that's a hard, sharp bend and the engine's gonna hafta work harder to pull air in, imo, but how can I argue with 2bad240's results? It could, however, be due to the opening of the "charge pipe" or neck as I call it, the part post throttle body. It's I.D. is wider than the stock plenum.

 

doesnt matter... this is a dreamer thread

 

I think most newb threads are.

 

sir yes sir

 

i love my 350z, but i quickly realized it wasnt going to be as fast as i wanted it without dumping a ton of money into it. sold it to a forum member, bought a c6z06, not even a year later i spent $8k to make it faster. fast forward 4 years, i wanted something quick, but comfortable and newer technology inside, got rid of the vette and picked up the ats-v, which is a great compromise for all the things i wanted

 

I get that. When I decided to forgo replacing my 15 year old FX I realized that I'd be good to build something that's "fast for what it is". The looks, practicality, awd and that it shares an engine with one of the most modified cars on the planet helped make my decision to keep it, restore it and make it quick enough to put a X5M in my rear view mirror. It'll get their someday. I appreciate those that take something other than an already very fast car and thrust their will upon it. I like the already really fast cars too.

 

I actually was following that link lol n was thrown off by what 2bad said. I could easily be wrong, but while following rzg, they constantly swapped parts (ofc). 12.04 @ 112, " The top of the factory manifold was cut off and sheet metal welded to create more volume with a 75mm neck to match the NWP 75mm throttle body.".

 

I'd just refer back to what he wrote in that thread. He went his fastest naturally aspirated with the Velocity. Unless he's getting royalties from Kinetix, I gotta believe him. The cams and higher compression may work well with it?

I do not believe that the large volume upper plenum did much if anything BUT I know the neck or "charge pipe" absolutely did.

 

I'm not calling anyone a liar nor am I discounting your findings/thoughts but if one instance of an otherwise modified VQ made more power/faster times with this setup while thousands of units have sold with either no gains, unknown gains, or negative gains my mind is made up. Especially when other intake mods do make slight (albeit) increases - such as the JWT pop-charger, Motordyne intakes/plenum spacers, NWT TB upgrade.

 

300whp with kinetix and supporting mods.

High 11s 1/4 mile. He does state a custom intake manifold, so im not gonna claim its a kinetix, hopefully 2bad240 adds to this thread.

and an oldie from Shin Beats....

Odd how the above link I added wasn't found. This should be good and on the page these quotes below were pulled from;

I switched from motordyne lower with huge spacer to the kinetix velocity on my all motor car and gained 4-5 mph at the track...

...and...

3.5" pipe and stock TB havnt tried it with larger TB on kinetix yet. and I switched out the custom tall intake to go back to the kinetix as the kinetix is faster .

 

Cool graph, never seen that post before. With a proper plenum, there should be no reason to fall off that hard after 6.2?k.
