Are you running a Pod Jazza? Would most likely explain the temps, used air from the radiator was probably being passing over; either that or the temp sensor was slightly placed incorrect.

With my CAI I see temps pretty much spot on the AT temp. Within a degree or two.

No I'm running the stock airbox actually, just with an APEXI panel filter. I must admit I was surprised that the reading was so high, though the fan could have actually been directing air around in the engine bay before heading into the CAI (I noticed the fan was completely missing the airbox as well as the intercooler), not to mention the whole car was hot from only just being driven & sitting out in the sun for 15 minutes.

There was also clearly heat issues with the smic as it did drop 7kw on the second run (you could see on the graph the torque dropping off right through the rev range. even though the boost creeps up a bit), though I'd be curious to see what the IT temp was on the second run.

Just out of curiousity how much power correction would you say there was Cubes? I do still very much agree with the dyno reading as acceleration at the top end for my car is far more explosive than it used to be with my old split dump (not as good a design & it cracked).

Thanks for letting me in in the traffic this morning by the way DriftR_33, made it to work with only 1 minute spare thanks to the fire at Jaycar

If assuming that Dyno Dynamics use SAE J1349 reference conditions, the reference temperature is 25C. If your IT was 40C, the correction would be roughly +3%. Conversly if the IT was 10C, the correction would be -3%.

Hmm if this is so, then my actual reading was roughly 164kW before power correction, which is 6kw less again than even my second run came up with.

Hmmm, would be interested to know what others were getting on their IT readings now.

My IT was 37.

What I wanna know is what the reference BP (barometric pressure) units are that DD are using. If its kpa, then I would assume that a BP of 101.1 would have a negative correction on all our readings as the SAE reference is 98.8kpa.

Might shoot Dyno Dynamics an email...

try and find my extra 20kw that i lost :(

my extra bits are

BP: 101.3 RH: 60 AT:25 IT:39 RR:013 TN:3.454

Interesting.... re the night time.

Would be good to go somewhere different also..

Blackwood auto and dyno has a good setup; from memory I remember they had windows that you could stand against and see the car running up.

There's also Hitech dyno.

Sorry Madaz can't say much from your Shootout parameters. Either your car has really lost power or the parameters from your last reading where whacky beacuse the current run seem OK to me right now.

And yeah a night time dyno would be sweet. But even during summer where its mid to high 20s over night, its still gonna be friggin hot!

Btw Cubes when I was in the cell I was sweatin in there? It seemed pretty hot. Or maybe because of all you onlookers expecting 1000rwkw. lol.

I found it......... I found it.......... It came to my car, i was reading 18kw more than last time on the same dyno WITHOUT touching a thing! :)

As for the night time dyno thingo........ would either have to speak to residents around the area or find a dyno in a industrial area, cos i don't think they would be too happy!

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By GTSBoy · Posted

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      Mistakes were made, my R34 Story

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
