Great thread except for the cat fights...

So is this car going to be raced, or is it a purpose built dyno weapon? If it does hit the track it will need full cage and chute i'd imagine.

For a daily driver did anyone think for a moment about the fuel consumption of 6 x 1600cc injectors...

I had a thought about the issue with dyno comps and light ramp rates. While talking with some tuners at a training event last time i was down south someone mentioned the issue of ramp rates being so light that some of their turbo dyno comp cars were barely achieving full boost for their runs. Where as this wasnt an issue of course for the supercharger croud.

I've read of some of the pro-mod drag cars in the US that use a nitrogen gas injection anti-lag system to pre-spool the turbo onto boost. As its not dependant on engine load this could be done to overcome lack of dyno/engine load during a power run. Basically they have a nozzel in the header before the turbine housing and inject nitrogen gas briefly to spool the turbo onto boost. The moment the gas is in the header it expands greatly because of the heat and eliminates lag. I'd imagine all the top dyno comp cars are running engine management capable of turning on a solenoid at say 60% load and above 5000 rpm, and off again at say 80-90% load and perhaps above 7000 rpm, thereby allowing the engine to settle and run on just turbo to max rpm. Just a thought...

we ran athids car on RE customs dyno the other night and it came up within a poofteeth of mine.... they dyno operator told athid it should be run in 4th (car was s15) and it ran 240rwkw..... ran it at re's and it ran 280 in 5th on 19"s with wheelspin... then ran it in 4th and it made 259rwkw.

not trying to wind you up here but your example is a little poor...everytime ive ran my car on a dyno in the night air its made more power...say 10kw minimum. Autosalon is run during the day and the conditions/air is not ideal compared to at night at workshop. Say you take that 10kw off the night reading...the dyno was out by 9kw!

Real world example...my car ran 467kw at Croydon the night before NAS last year...the next day with hotter more humid conditions combined with fuel/exhaust gas in the air it rolled 450kw. Was it because the dyno/ramp rates were wrong...no its because the conditions were not ideal for the car to perform to its optimum.

All cars in dyno comps are supposed to be run in 4th or 5th depending on which gear is 1:1 eg 5 speed in 4th or 6 speed in 5th

The role of a professional operator at a dyno competition is to eliminate as many variables as possible. The thing people forget is that a dyno is a scientifically designed and constructed piece of precision equipment and by far and away the biggest variable is THE CAR ON THE ROLLERS!

You can regulate tyre pressures, gear ratios, ramp rates, dyno modes, corrections etc all you want but the biggest variable will ALWAYS be the car.

Period.

yeah everyone was out, we ran athids car on RE customs dyno the other night and it came up within a poofteeth of mine.... they dyno operator told athid it should be run in 4th (car was s15) and it ran 240rwkw..... ran it at re's and it ran 280 in 5th on 19"s with wheelspin... then ran it in 4th and it made 259rwkw. If it had had been done properly athid would have taken out 4cyl turbo EASY... (LOVE THE BULLSHIT ABOUT HIGHER READINGS IN A LOWER GEAR)

DARRENs supra from ran well below its hp level (400hp off on sat) until sunday when it got tweaked to suit and rocketed to top position... only to be outdone by GAS on the last run of the day.

Angelos r33 GTR from racepace ran mid 314rwkw.....well down so it was pretty much all workshops with odd readings..... not foul play just poor operators.

shit even a R32 GTR pulled 140.... talk about sad..

What GTR ran 140kws?

mine is the evo that ran up 310.8kws (they only gave me 2 runs) dyno was probably out but not by 50+ kws.

ummm you just posted it yourself... :dry:

I knew Osman's did some strange things like remove all the seats in a WRX convert it to a ute and run a single seat in the middle of the car....but remove the turbo's off a GTR is wrong in the extreme.

The "No" refers to no NOS, the "turbo" means it is running a turbo - notice some others have N/A in this field.

haha you spend too much time typing...... and coming up with conspiracy theories :laughing-smiley-014: dont get me started with you just plain reading into things that just aint there..... i dont know how you find the time... im too busy on the dyno all day to keep track of it all...

just thought id let you know that i looked at athids dyno time (@RE's) it was 2pm about the same time as MAS ambient temp also about the same (within 2degrees of MAS) dyno graph below. didnt check baro as frankly i couldnt be fkd.

agreed cars are always run in 1:1...thats why athid had the whinge every one knows s15 are 6 speed, and 5th is 1:1.

oh and ignore the boost levels ray had some boost scale issues on the first few runs, all runs were 23psi. feel free to ring and ask him if you think its another conspiracy :P

Well that is within a KW or 2 of what it makes @ Dr Drifts but then again he has a chassis dyno which means lots of wheel spin :P

would be interesting to see some other cars on your or rays dyno, might see if some can pop down next friday to RE

yeah ive done 4 cars now, one on rays, one str8 from sabbadins and two from T&E ?? in paky all with in reasonable limits. Rays was a good test for differrences between 4 and 5th. I ve also had heaps of remaps come in from DRDRIFT that i have tuned that pulled close to thier sheets on my dyno before we started any work. Pretty sure DRDRIFT's is pretty much always spot on... it should read the same as MPC's as its the same dyno :) There should be hardly any wheelspin at a lowly 260 rwkw...

But you said in your post "the other night" so was it at night or 2pm...lol

it took of a minute or two reading your excuse to come up with the theory at 11pm after a few of Coopers pale brew's.

LOL mate i understand i dont know if im martha or arthur im that busy little own the time of day or nght i went down there, had a few mag editors in here the other day doing a BEFORE and AFTER article which put me even further behind.... days hours have no meaning anymore :P its just light and dark and lots of dyno noise.... if im lucky i get to visit the engine room....

ahh well...while your busy $$ are rollin through the door...and your not at the pub. :(

what are you doing posting in here anyway...i thought you were tuning all day ;)

now get back to that dyno where you belong... :P ...bad tuner...bad tuner!

    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
    • The video for the servicing and fuel filter change can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44 One of the main jobs I wanted to do before the car officially went on the road, was to remove the awful looking blue silicone hoses. There's nothing wrong with having coloured silicone hoses, but I realise as I'm getting older I prefer monotone engine bays with a splash of colour on the engine cover(s). I cover this in a lot more detail in the Youtube video, so unfortunately there's limited photos of the process. The intercooler, upper radiator, boost vacuum and upper breather hoses were all changed to black silicone with mikalor clamps. The only blue left is a blanking cap at the back of the inlet manifold and the GReddy pulleys (which will be replaced for stock when the cambelt gets replaced) While the intercooler pipes were off I gave them a quick clean/polish too A before photo I do have a replacement air filter on its way. Fuse box covers were painted blue, they're now satin black Another job on the list while the bumper was off, is to add some mesh https://live.staticflickr.com/65535/54737966256_99b28bfa30_c.jpg[/img] I was hoping to use some thin wire to secure it, but it seems I've misplaced it and the wire I had was too thick to twist easily. I ended up using cable ties for the time being https://live.staticflickr.com/65535/54737131882_c2b7989dcc_c.jpg[/img] Was pleasant to see this https://live.staticflickr.com/65535/54737131627_8b2aab13b3_c.jpg[/img] The last thing to do was to fix the front grill and re-mesh that to match but I ran out of time The Youtube video can be seen here: https://www.youtube.com/watch?v=R4FsF6tgizE&t=23s
