After a year and a half of my power FC sititng around in my attic, i finally got soichi to install and tune it.

Questions

my intake air temp is getting to 40c-45c degrees , is that normal.

other power fc users, what is your water and air temp reading?

I have pods and a heat shield. I even have water sprayers on my intercooler. I live in auckland and on a hot day you can expect the outside temp to be 20ish at best.

The water temp gets to around 85c degrees max. I think this is normal and ok.

Specs.

R33 GTR

Mods :

Forged internals - unknown brand

HKS Split Dump Pipes

Trust Front Pipe

Custom bent 3" tripple muffler exhaust

My intake temp is roughly 45-50 (via the PFC/sensor etc), i cant remember but will watch tonight on the way home.

But then im running un-enclosed pods, with a suspected restriction in the cooler...

So thats to be expected really.

We need someone running an airbox to post up :banana:

I see reading of above 50 in my car. Quick spec is a 2.8 litre, twin gt rs's, GT block. I am still running the stock airbox. Could it be the location of the sensor being in a less than ideal place? Perhaps a close as possible to the intercooler outlet is a better place?

This may be helpfull. Should be easy enought o nut out. Temps were from a turbo rotor with an unshielded airbod. What you are seeing is pretty normal.

Results from dry road testing on the weekend.

Conditions: Ambient 15 deg. Drive down hwy at 100 k's, brake and accelerate from 2nd gear throught to 8000 rpm in 4th, cruise for about 30 sec and the accelerate from 3rd gear to 8000 rpm in 4th. Stop and idle for about 45 seconds shortly after.

Temps at 8000 rpm in 4th for first test:

air filter 48

after turbo 117

after I/C 45

throttle body 51

Temps at 8000 rpm in 4th for second test:

air filter 47.3

after turbo 122.6

after I/C 45.9

throttle body 53

Temp at air filter after stationary at idle for about 45sec was 84 deg! Thermo fans switched on and filling engine bay with hot air obviously.

thanks guys, epic stuff.

the temp sensor for the GTR is on the plenum so some of the heat from the block would sink into the plenum the longer the car is run.

Thats for clearing that up. Feel ok about my temps now. This morning i went for a long drive and it didn't go above 35, so I guess i should be happy :banana:

ok 35 degree's tonight up in the hills, ambient was around 8degree's...

Mind you the car was taking an absolute beating (didn't see under 5000rpm and water temp was up around 74-75 when its normally 69-70)... so it probably could have been as low as 30 for intake

In 'normal' weather with ambient around 20 degrees i sit around 45, and upto 55 in peak hour/stop start.

All thats with pods, NO CAI.

Cheers.

    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
    • There is a warning that "this thread is super old" but they ignore that anyway...
    • With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
