** NEW INTAKE MANIFOLD ** long awaited, with pics
With a little luck, lsdunique will get me out an engine cover so I can put the package together and provide some pics. Here is what you asked for:
The dynos provided by Sungnam have a slight "anomoly". The areas circled below are where the peak HP and TRQ numbers are made. This huge spike is normally caused when the dyno operator releases the throttle before pressing the button to stop the dyno computer from sampling the run. The dyno computer freaks out in this situation and registers a spike. I don't know the mechanics behind it, but I have seen this happen on our own dyno. It is adding anywhere from 10 to 20 peak HP to the chart. Can we see the other two graphs?
Are we going to have to get an ECU reflash to run this safely in NA applications? I want to wait to do my ECU for until I get cams (probably a little while off), will this intake lean out my AF ratio to the point of being unsafe?

I noticed this and probably should have jumped in sooner. Though it appears the dyno operator let up before using the dyno brake, it is easy to see the separation (gain) prior to that happening. At 6500rpm, both curves are still rising. It's shortly after that when the original dyno drops off. I'd say that is a good measuring point anyway as many people do not have a reflash to raise the rev limiter. At that point on the dyno provided, the gain still appears to be about 25-30hp. It is safe to assume, while probably not quite 55hp, that the gain continues to increase as you approach 7000rpm.

When a car is racing towards redline while your watching 5 different gauges and listening for detonation things get hairy. I just wanted to see the other graphs. No harm in that right. The runs were made, why not?

Motordyne Plenum Spacer vs. Kinetix Intake Manifold
the 1/2 inch one is the way to go if you are going to get the motordyne plenum spacer. its the spacer designed for most power gains and an audible difference. if i get the motordyne spacer, i will get the crawford strut bar (i dont want that ugly hood STB)
so if you do the math, it is 200ish for the motordyne plenum spacer shipped + 170 for the crawford STB = 370. but then i figure if i am going to spend 370 on this, i might as well shell out another 300 and get the kinetix racing intake manifold, which should be priced around 650. i think me and you are looking at all the same performance mods. my car is bone stock, asides from aftermarket wheels and tires. i plan on sticking to a NA setup, because i just dont want to shell out 7000 for a turbo or supercharger installed.
so i figure....
1. kinetix intake manifold - 650
2. injen cai - used for 100, new for 200
3. injen super ses - new for 750, used for 500
4. kinetix HF cats (there is a gb on these and the new intake manifold) - 325
5. UR crank pulley and belts - used for 200, new 350
these parts are easy to install, so at a shop, install costs wont be too high (not 500 install like with headers). altering the upper and lower plenum is what allowed the 05 350z to make 300 hp. the kinetix intake manifold, although NA dynos arent out, i think it has potential to create a 20 hp gain when used with mods 2-5. this 20hp gain will be in addition to the power gained from mods 2-5, so i am thinking somewhere in the ballpark of 40-50 hp total with using these mods. if i am right, as the kinetix NA dyno will be released tomorrow, that is around a 20% gain in power for around 2000 bucks (if you buy the parts of the classifieds).
i dont know.. i might be rambling... but if those mods cant create a 30+ increase in hp, i will just get the motordyne spacer (1/2), crawford STB, jwt popcharger, some TD exhaust, and some HFC. i should be able to get all of that for around 1000. power gains should be around 20-30 hp, decent for the price. its times like this when i wish i had a supra tt.... if you invest 2500 into the 2jza engine... you would be throwing down more than 500 horses. truth is, if you dont go FI, you cant get any real power gains. hopefully the kinetix intake manifold dynos will prove me wrong

Those would be pretty optimistic numbers for NA, especially since many mods give decent gains, but at different points in the powerband.
We have been slightly delayed, so we hope to get the dyno numbers within a couple days, as we were hoping to have them done tomorrow (wednesday) but it looks like thats not going to happen.
Also, the manifold wont be 650 in the group buy, its going to priced more around 700. That is a serious piece of fabrication , and at 700 it is quite a deal considering how much work and welding is required.

j/k... mcduck must remember... patience is a virtue... unfortunately, it is one he does not possess!

It bolts right up to your current throttle body. So, NO problem bolting up to Vortech SC. Kinetix did an excellent with manufacturing. It should allow everyone using current TB to make the switch to this IM with NO problem. While I had everything removed installed PE 380 Injectors and returned by ECU to TS to reflash for the 380s. Prior to that they had flashed by ECU with "Limited Flash". If you have more questions, ASK!
