From a technical perspective:

Dyno is SAE compensated for ambient temperature, current temperature (used to be called intake temperature), humidity and atmospheric pressure.

This means that on any given day, a normally aspirated car will record the same horsepower.

What is not understood by many is that the way turbocharged cars react to heat and cannot be quantified or corrected.

Everyone knows how flat their cars feel on hot days.

Pneumatic and non closed loop electronic boost controllers cannot correct for ambient changes.

Far from ideal temperature compensations in the engine management strategies, so you see excessive timing retard and fuel correction, and there wasn't a car there today that had fuel delivery temperature measurement/compensation.

The dyno is only a comparitive measuring tool. It has given relevant information about the cars tested on the day, compared to each other, on the day, not last month, or another dyno at another time.

The Autoworx facility was the most recently installed and calibrated machine in WA, so I highly doubt it reads wrong, low or whatever, but suspect that many of the cars are victim of nothing more than the classic old turbo's and heat drama.

But all in all, thanks to all for the turnout. Was good to see some of the old faces, and so many new ones.

Right on Lumpy

Thank you to Paul and all the guys at Autoworx for getting us on the dyno nice and early!

Much appreciated - made the family lunch right on time!

The result of the Stagea really did surprise me , and made me a Sad Panda too :)

Oh well least I know HOW rich its running. I am surprised we didnt all feel like a little sleep after her run.

the Silvia went about as I would have expected.

At least Loretta now knows there is a LOT of improvement to be made in her car without even changing anything ( other than the ECU or getting a piggyback )

Videos are still uploading *sigh* god damn high def.... 20GB for less than 40 minutes of footage...

Here they are so far, I'll keep adding them to the playlist as they upload -- they should all be in order:

SAUWA Dyno Day - Youtube Playlist

Great video's Levi. HD power runs :)

I'm blaming the Haltech pulling uber timing due to the heat :) 220awhp my ass :)

But at least I know now exactly how shit the tune is :) on the plus side.. it wasn't lean anywhere so I wound some more boost into it on the way home :)

Cheers for having us!!

To be honest, with the exception of the Hilux, most cars there definately had conservative tunes with there fueling, and there wasn't any pinging even on such a hot day. Most of the cars with ECU's would have had the timing well and truly retarded, which would account for much of the power loss.

Yeah I'm pretty sure everyone understands it's a tuning tool above everything else, though you can see the power loss throughout the cars is pretty even :) ~300hp cars are mid 200's, ~400hp cars are in the 300's, 2 very noticeable differences was Bart's GTR & Mikey's GTS-4, down about 150hp on what they have done on other days. There's always a downside to lovely pool & beer weather :)

Advan Performance 680hp

Hyperdrive 633hp .. 702hp with 109 n timing in

Autoworx 519hp

As i said already the 10second passes on a 30+ degree day is more rewarding :):):)

Bubba tell me more ! what motor you got in the Stagea? The Rb25DET Neo ?

so you were running AWD too yeah?

Yeah 25 Neo and yeah was in awd, got an unknown hiflow on it and was running 12-13psi yesterday. Got the old 550cc injectors out of my skyline to go in when I've got the cash for a tune, then I'll wind the boost up to 18-19psi and see how it goes.

aah.. I dont feel so bad then !

fark I couldnt beleive it when I saw the power ( or lack there of ) , trying to convince her to get some form of aftermarket ECU,

I am no Math Wizz but I am pretty sure that the ECU would pay for itsefl in not too long if she is guzzling that much fuel

Sean, PM replied mate :thumbsup:

*sigh* while im not really too worried about power in this car, im not happy with 138 at all :D I could have sworn it would make at least 150, maybe 160... Perhaps time to seriously consider bolting on the turbo

Good point and I actually see this as testament to how the aftermarket scene has matured in Perth. There is tuning from at least half a dozen workshops represented yesterday and as Paul says AF ratios and knock levels were in the majority of cases very good.

+/- 12 HP is less than the error range of the dyno. :D

My car made 252rwhp on Hyperdrive's dyno, at the Silvia WA dyno day,3 weeks ago. All I did was replace the restrictive stock intake pipe with a 3" bend. Same boost.

On sunday my car ran 261rwhp with that hot weather. So I am not complaining.

Must be the Wolf V500 ecu I have :)

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
