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 :)

    • Cheapest Jaycar one is only $65.
    • Probably best way would be using a proper dB / SPL meter lol Buy one and ship it from state to state to have a consistent test device lololol  
    • Not electric car good of course, it's still just a crappy old ICE
    • Yeah, but the good news is that can all be tuned out...the V37 has excellent throttle response now, and with the tiny factory turbos is pretty quick without lag
    • I did change bodyshops. The most recent place was very fast. I think the trick is to have smaller, simpler jobs. A front end repaint and some (extensive) sideskirt and fender stuff is a 'small cash' job for them. It was expensive but 'worth' it purely cause: 1) They did everything great 2) They did everything fast Get what you pay for maybe? Pictured: Very stock looking car from my very old phone. I did realise that oncoming traffic would probably be like "Oh look at this guy, commuting around in a GTR!" (until they see the side profile). This is the sad state of my fender liners and front fitment with my current stock GTR sized wheels (18x9 +30) This is how the rear sits with a 25mm spacer. I say 25mm because it's actually a 20mm spacer sitting on the studs which are ~30-31mm, and the wheels have a ~5mm cutout. So... this is very not safe to drive. This is the other side.. .with a 22mm spacer. Yes, the studs are ~27mm. Yes they're different both sides. I spent a fair amount of time measuring. This was the old pod setup behind the box in the past. Old vs New Pod she tells you not to worry about:   Turns out I measured this pod filter pretty damn accurately which I was chuffed about. I went for a ~3hr drive for 'testing' reasons up into Healseville hills. Believe it or not, the induction noise is the same between small and large pod. I guess it has more to do whether a pod is *present* or not, and the diameter of the pipe. It does sound very decent in cabin though (and extremely 'smooth') - Though behind the car the exhaust noise is nonexistent now. So uh, it's all for the driver. I'm confident it has to be quieter than @Dose Pipe Sutututu's car. I should test it. Is there a way to do it with an app or something we can both agree on? (we are both very old men now competing for quietest car) I've texted Trent at Chequered to book in to see some before/after. I can now twist the pod entirely out of the engine bay on the dyno to really rule in/out any intake restrictions. And/or remove the pipe entirely which I will probably do for testing reasons. The logs show *maybe* a difference in ambient KPA vs Intake KPA at wot. But I'm talking the difference to -3/4 before to maybe -2/3 now. The tune is not wildly out or even changed at all. The only takeaway I have is the car is on 17% ethanol as it's still got the fuel from the dyno in it. It's plausible that that tune would have resulted in the car erring on the side of being too rich (it was) and right now it seems to be bang on perfect or within -0.5% either side of target. I was tempted to take it to a Drag day to see what MPH it would trap (and tune the car) but then I wouldn't have a number and a pretty line. I may do that after I re-hit the dyno, purely to go to LS1tech and shout about how their dynos are all very inaccurate while my low HP car traps the same MPH as cars with the same setup in the US, who make 375RWKW (supposedly). It was safe to say Mr Mamo was not really happy with me posting the results yet. So I owe it to at least try the intake thing for my own sake and not besmirch people who want to buy a similar USA heads and cam setup and get disgusted that they make lower HP than simple bolt-ons which can be up to the "330rwkw+" kw region over there - Which here equates to about 270kw. (and runs the same 115-118mph)
