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 :)

    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that.
