Nice effort Tristan, for a street car that's more than enough power - especially in a 2WD.

That dyno mpg shows a few things which have been a source of questions though. I can recall Paul or Steve saying that the reason why intake temps are so high on their dyno is due to the fact they run it with the bonnet shut. That run clearly shows the bonnet open, and if you look on the dyno sheet it shows the intake temp up at 63 degrees.

To the best of my understanding, all dyno's record an uncorrected level of torque, then reference that to RPM and calculate power. After that primary calc is done it then factors in the correction, which is based on humidity, temperature and altitude. I know that's a basic rundown of the whole she-bang but for the sake of this arguement it will do.

If you run those weather conditions through a dyno correction calculation it actually multiples the amount of power recorded, mainly due to the extremely high intake temps. Hang on will do the math and post the actual correction factor.

So just a quick question - where is the intake temp probe situated?

Don't be hasty and think I'm having a go at the car, it's owner, the workshop, your pet etc. I'm more interested in the correct way to extrapolate consistent data from a dyno, moreso than what is currently being shown.

LOL...for gods sake you are in a workshop...take the tie off:) i flinched when i thought you were about to lean over the engine bay, i have weak nerves so pls dont lean over a running engine with your tie on :)

Seems to come onto boost nice and hard....what boost was the thing running?

I too cringed like a little girl when i saw dude in tie lean over the engine bay!!

I'm over the whole scene of this 511 hp stock injectors car cr*p. Until someone post up a mph that reflects the representation of the claimed hp. So until then it's still a claimed effort , and i'm claiming mine to have 900hp atw, and i'll post the dyno sheet tonight, But don't hold your breath on that one either.

hungry6 your a tosser. In the other thread tristan said that the 511 was an overinflated figure. If you watched the video, youd see it shows 438rwhp, which is the CORRECT figure. And yes on STOCK injectors. So take you 900rwhp dream machine and fly elsewhere, when you actually have a car worth posting about, then dish out on others...

be nice everyone. Im not going to be nice this time :)

boost seems to come on like a hammer!

My car is sooo nice and progressive with my GT30 compared to that, very savage!

tough to drive on the street?

Doughboy. the air probe is right in front of the compressor housing, my air filter is causing a minor restriction so i took it off before the dyno run.

Roy. Peak power the turbo is running 18psi

sorry dave wont wear a tie next time.

Crack. about 6500rpm to get that figure

Hungry6. . <- you

D1 RX7. nice bit of chop dished there.

r31nismoid. you dont have to pump the clutch to get it to break traction, your coming to perth, you can have a drive.

Then why did he topic this thread with 511 rwhp?

There is only one tosser here and it aint hungry6

Prolly shootout mode which is made to compensate for inconsistensies on the day of the dyno run.Correct me if i am wrong.

You are wrong.

The 511hp was made at Perth Auto Salon using a hub dyno.

Autosalon figures should be taken with a large grain of salt, cuz in the end, their only purpose is to put on a show.

The 438hp was on a dyno dynamics dyno in shootout mode. Which is a fairer representation of the cars true power. Since Dyno Dynamics dynos are widely used when comparing HP figures.

The first thread said 511rwhp on stock injectors, people questioned the figure and wanted to know how it could be done on stock injectors.

It was then acknowledged by the workshop in question that 511rwhp was a BS figure and the cars true power was ~450hp, which has been shown on the recent dyno.

This whole debarcle is over a big HP figure being made on stock injectors, people questioning how it can be done on stock injectors and other people not telling how it was made.

I'm just here to enjoy the resulting show :)

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
