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 :)

    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
