The 50-70 is the RB26 equipped people (im one of em)

Im beginning to think that because of its position, its getting some pretty bad heatsoak and not giving the true reading.

I will toy with the option of moving it somewhere better i think to see if i cant get a better reading as it takes a good 15mins to my temp to creep upto 40+ on a cool day where the pipes feel the same temp after 5mins driving or 30 :ermm:

a set of gizzmo inlet gaskets makes a world of differrence.

I was thinking about the pressure danger side of things and remembered something a hydraulic engineer said to me. A pin hole in a hydraulic hose can squirt out hydraulic fluid with such force that it can cut. Worse is that when it cuts the skin and fills a cavity in your body with hydraulic fluid. Now consider that happening with liquid CO2, injecting liquid co2 into you, which then freezes your tissue before converting to a gas (possibly in your blood stream). Sounds like a pretty nasty way to die to me.

Yay! finally someone else who has the knowledge/sense to bring up the dangers of high pressure and/or co2!

They insulate the plenum from the hot runners.

thanks mate....umm i know what the plenum is, just took at look at my car and there is a sorta brown/beige looking gasket but what are the hot runners?

Is this gizzmo item a worthy investment? will i see lowered intake temps?

ill do a search in a sec

I might be thinking of a different brand then, but I'm sure there's one out there that goes between the plenum chamber and runners.

Johnny, the "runners" are the individual tubes that go to each port :)

Just for a sensor though its a bit of effort.

When the car is full noise the heat i dont think would really alter it that much ???

So relocating the sensor would be a darn sight easier than taking the entire plenum off wouldnt it?

Exactly! It wont make any diference. Consider air velocity as its entering the plenum (after coming out of the intercooler). Its not sitting in the plenum for a minute soaking up radiant heat. Its on the move and straight into the engine.

Reminds me of a twin turbo lexus 1uzfe v8 I was messing around with a few years ago. After 2 minutes on the skid pad held wide open at 6000-7000 rpm the plenum was warm but due to a good intercooler the AIT sensor never read above 35 degrees. Also, there was condensation all over the throttle body due to the pressure drop that was constantly there as the driver got off and on the throttle. The throttle was actually cold to touch.

    • Hey all, not sure how active SAU is anymore but will ask away anyways. Just wanted to get some experience on the 2008 model GTR CBA model.  I've hit that age in my life (43) where I'm like fk it time to get my dream (midlife crisis) car. Looking at importing one in and seeing if these can be reliable if the main flaws are fixed up. Plan is to keep money aside to do the following straight off the bat to future proof it: * install a stage 1 rebuilt trans with all new bits and pieces.  * install a new Bellhousing from the later model GTRs. Or potentially an upgraded stronger version like MAD or ATR. Besides the above two things and typical maintenance items anything else you'd recommend doing.   Been speaking to a few people and the engine on these are very reliable apparently. But keen on the view of the community here. Hoping to find a nice grade 4.5 with low mileage in Grey. I'd go black but swirls too easy. Look forward to your responses and feedback. Cheers    
    • Do Alan and Keith work on Skylines now? I remember buying stuff from them when I owned my Ralliart Lancer a few moons ago. Definitely genuine guys and be excellent if they dealt with the skyline platform as well.
    • Hey all, I'm Gaston from Sydney's West.  I was a member on here when I was a younger lad and owned a mint R33 GTS-T. Ended up selling it and getting married having kids (yadda yadda) we all know how the story goes. Now I'm back with the intention to get my midlife crisis (dream) car ... a R35 GTR.  You'll see me about asking questions and searching the forums. Good to be back and can't wait to get back an Import again.
    • I have to put something here in order to post the photos. From what I could gather there's more enthusiasm for modified cars now than there has been for years. There were probably more younger people there than older (me included lol) which was a good sign.  It did seem like the record least amount of representation of the 90's era hero cars on display though. Like maybe one or two examples of S-chassis Nissans, and maybe 3 or 4 R-chassis. By comparison there were a lot of Civics from that era but in all there were about 10 - 12 EG/EK Civic Type R.  Euro exotics are always there in large numbers, led by Liberty Walk...... say what you will about kids using markers to scribble on a Ferrari F40, it did seem like a stunt to infuriate Ferrari enthusiasts, or Ferrari itself. I wonder if there's something more to it. Either way LBWK have done some heinous things to a Lamborghini Miura this time. They should stop now.
    • Engines and drivelines are not war stoppers for me mate, busted arse bodies and un-obtainium parts and panels are though Both cheap Brumbies I looked at had trashed tubs and a fair bit of rust
