We got our Skyline back from our tuners on Friday and took it to a airfield track on Sat for a shakedown. The cars now running 500bhp at 1.5bar, 428bhp @ wheels ;)

Check out that power curve, awesome :notworthy

Some footage from Elvington on Sat. Bear in mind Im out for a bit of a prat around and to find the limits of the car, Im not going for ultimate lap times:

Right click and save as, 10.3mb

What 500bhp does to a poor unsuspecting passenger. Be warned LOTS of bad language:

Right click and save as, 6.8mb

Good result... the videos are amusing. ;)

Interesting venue where ur out at aswell. Looks almost like dirt hehe

I reckon if you spend a bit more time on the dyno there is some decent mid-range to be found there.

(if im doing the numbers correctly :))

You have around ~230rwkw @ 5500rpm

And then only ~260rwkw @ 6000rpm

Here is the smaller -20g for comparison

I reckon you can have a lot more in it.

Just a question, on the graph its making 1.5bar from before 3400rpm, is that an error or something? Its a little small for my eyes ;)

The graph is correct, the car runs 1.5bar from 3500rpm to 7500rpm :O

Its an airfield made up of a mixture of concete and tarmac. Theres loads of run off so its nice and safe to learn the capabilities of the car. We are trying to get it booked into a 'proper' track this week.

How would we get more midrange without a boost spike? The power delivery at the moment is excellent, very progressive and predictable. The car would actually be very usable for drifting as it is so responsive and has so little lag. Or at least it will be once I get rid of the Hicas.

We are hitting a bit of a brick wall at the top end, more boost just moves the entire power curve to the left a bit but peak power doesnt change. Any ideas? We think maybe the throttle body is a restriction.

Its taking a very long time to make power if its holding 1.5bar for over 2000rpm before the solid power arrives.

Whats the exhaust like? 3.5" or more?

Hrm... the tuning experts will know more :whistling:

It runs a 3" quiet exhaust and we have plumbed the external wastegate back onto the down pipe so we can pass the track noise restricitons. I have a more free flowing exhaust on order and we are looking at a mini silencer for the wastegate so we can seperate it from the downpipe :3some:

3" with a plumbed screamer...

I reckon thats the problemo right there.

I lost HEAPS of response when i had my screamer plumbed in as i only had a 3" exhaust.

For that power you really need 3.5 or better yet a 4" :whistling:

Nice work :whistling:

Looks like there is still alittle bit more I can get out of mine then :kiss: 1.5bar at under 4k? thats nice...my GT35R isnt on full song until mid 4k rev range

might have to remove the plumb back pipe on my screamer and see what the results are like then Ash :3some:

Cheers

JB :laugh:

dude that thing looks like a weapon..... now why cant i get power and response like that out of my setup!!!! :whistling:

also justa a question, u still running standard gearbox???

Standard gearbox but its starting to crunch into 4th and 5th. Not sure if its a syncro or clutch release issue.

Bren,

Out of interest, what size is the exhaust housing on the TD06-25G?

Greddy (Trust) list 8cm, 10cm and 12cm housings for the TD06.

Cheers.

Its known as a 25G, I dont have any more info than that to hand Im afraid.

Either the passenger has spent his entire life driving excels or the difference between power delivery from the driver and passenger seats is way different because ~300kw feels like im driving a bus. Then again, when it comes to braking for a corner you suddenly realise how fast you are going.

Who's job is it to realign all the cones when somebody has an off?

He was at the track day in a Pugeuot 106 if thats gives an indication of his expectations :)

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • 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.
