using the 05 track oil pump...

have i listed all the parts i am going to use yet?

didnt think so...

 

reduced... though since I have been driving it more some of it feels like it has came back... I can only say feels because i do not know if my hp / tq curve has actually changed...

but... i can break the wheels loose easier at low RPM's now which is a good sign...

i wish I had my ecu worked on sooner then later... i want to take my motor above 6700 but that will happen soon... before the car felt like it wanted to pull a little bit harder and higher... but now with the new mid plenum the car comes to life at 5700...

 

I am not going to be using the 12:1 46cc nismo heads that are currently available...

found something better

when the motor is done... all the parts used will be spoken of...

there is a differnet mid plenum that has just come to light... just trying to get my hands on it... if I can... ill be ditching this one too...



my Z is not going to be a daily driver much longer...

 

What's different about this mid plenum? Can you tell us more?

 

Jason does the "something better" start with a T as far as the heads are concerned.

 

Radical cams with long durations usually only lower compression ratios at low RPM's not higher RPM's. The lowering of compression at low RPM's gives you the bottom end loss everyone always notices when they put a more radical cam. As the RPM's increase so does the compression giving you the mid or top end power. You can put a 12:1 static compression engine and put cams in it that would allow you to run pump gas but the engines dynamic compression would be lower than 12:1. This probably wouldn't net you any gains caused by the higher compression. If your dynamic compression is 12:1 then you will definitely see a benefit but would need to run higher octane fuel or pull alot of timing.

 

Do we have an expected TOA on when "all the parts used will be spoken of"? Or is this going to be a year long build up?

Off-topic:The arguments, anticipation, development, and knowledge sharing here is second to none. No sitcom, soap opera, or "reality" show will ever be able to match the addictive qualities of this forum. Sorry, following this thread has reminded me of why I spend so much time here.

Now, back to finding out what Jason's putting on his car...

 

Yes, I'll get the logs Monday off my work computer, since they're no longer hosted, but cliff notes are an internally stock VQ35+ARP rod bolts doing repeated 7500rpm blasts.

Also, you might try SEARCHING before posting such BS blanket statements. Here are a few examples of people miss-shifting and hitting 8000+rpm without valve-to-piston damage:

Also dozens of people on Maxima.org, including myself, have mis-shifted 1-2-1 or 2-3-2 and revved these things well over 9000rpm with NO adverse effects to the engine. My stock engine (arp rod bolts) is holding up perfectly fine with the 7500rpm rev limiter. I shift at 7200 due to the current powerband but it blips 7500+ between the shifts when I don't lift the throttle.
My ARP, 7500rpm info has been posted on this site before. I suppose I can make a new Zeitronix log to show off but I don't expect the doubters to have enough sence to read and understand what they're seeing.


If someone wants to discuss this further then find my ARP thread so we don't hijack this thread anymore.

 

Bump for an update!!!

 

bumpity

 

So you might have lost some low end, but gains above 5700 RPM with the 35th anniv. lower plenum right? You think maybe it is kinda *oversized* for a stock 350z and somewhat starving for air without perhaps a larger upper plenum, throttle body, and air intake (cai, JWT, etc.) and then maybe some exhaust work starting with HF cats or TP's and new Y-pipe or exhaust?

Sounds to me like it will only improve with more mods throught the entire power band. I think I am pretty much on hold with anything intake related, awaiting 350EVO and whoever else to design their complete sytem.

 

the lower plenum don't forget was designed for use with the VQ motor with full variable timing, which, like most cars with such fetures create lower torque numbers and higher top end power. The car could use a bump in the redline to benefit 100% from this, but it's still a good mod. Jason is going to put his crawford plenum drive for a day or so and dyno the car again here within a week hopefully, (time allowing).
We're expecting decent gains again

 

Yeah, that's exactly why I'd like to see what a stock '05 Track/35th dynos for comparison.

The 2005 ECU, cam(s), and exhaust cam VTC control alone could make up for the loss he's seeing and even make the top-end improve.

 

Im taking mine too 7300 daily and its lovin it valves start too float around 7300 though.....

 

What ever happened to the new 35th aniv model pistons and rods? Have they been tested yet? I would really like to know how they hold up compared to the regular ones in a f/i situation!

The REV-UP rods are Heavier then the 287HP motor. As them being stronger, if you were to upgrade the stock rods with stronger bolts like the nismo rod bolts then that would be a better bet... Lighter rod on the 287HP motor...

The Pistons have a differnet valve releif angle so would have to be used with the new heads which I suspect have a different chamber angle which would actually not help horse power but may actually bring it down a little.

 

Huh?

 

Exacty what I was thinking.

 

I think Jason is kinda repeating what he has stated before... the weak point of the stock internals is the connecting bolts. And you don't wanna use the new rods if they are actually HEAVIER than the originals, that robs power. If you are staying n/a especially. Nismo springs and connecting rod bolts, rest of engine is fine for most everyday applications, upgrades, and rev. limitations.
