Thanks mate :) Yeah a bit of side by side fun would be good :cheers: First things first though I want to concentrate on getting some decent numbers.

Shaun will be doing a bit more tune work tomorrow (the CR allows more timing to be added) so a few more rwkw would be nice. If we can sort the boost drop issue (small but worth rectifing) before the nats that'd be nice too.

I guess I could go crazy with boost but to be honest I'd rather keep it closer to what I'll run on the street. I'm not out to set any records (don't have the power for that) Should be good fun :)

Hip,

Yeah a decent shock upgrade is in the pipeline (shocks are the only sus mod left to do).

Busky2k,

I'll be at the Nat's, but who cares about my car I want to see Munro & Keir running 8's

Matt,

Yeah mate nothing but good ol' as it comes out of the pump BP98. Hopefully later today we'll get to see how much more it can make 'safely' with more timing & a bit of octane boost.

We did another tune today. Added an extra 1' timing. Got a nice even 280rwkw on 1.3bar. The wastegate is creeping up top so it drops to ~1.1bar. After we sort out the actuator it should hold boost & make a few more kw up top. Dyno sheet to follow soon.

Only downside so far is that even when hot the RE540S's no longer maintain any traction ;) This on 1.1bar road tune. Haven't tried 1.3bar yet.

The LT12 handset is able to hold 4 maps, so they are set as follows:

1. 'Valet' - 3000rpm limit / 3500rpm cut

2. 1.1bar road tune

3. 1.3bar road tune

4. may become ELF LMS drag tune

All depends on the right foot mate. I got 260k's from 1/2 a tank during the mild post 1000k run-in tune. I'd be pretty happy with ~400k from a tank with mixed driving (cruise/WOT etc...) Heavy driving & I'd guess 200-250k? Can't have everything ;)

Once I've done a few k's I'll post a report on economy.

Very good question mate. Yeah I have had a stab at the average power (sydneykid style)

I know the power curve stops before 180km/h but I'm guessing that the power would drop at a similar rate hence I can estimate power at 180km/h mark (it should improve in this area once we get the boost to hold).

So based on the above my average power reads as follows:

3,600 - 213wkw

4,600 - 272rwkw

5,600 - 280rwkw

6,600 - 245rwkw (boost drop takes effect here - "should" improve with new actuator)

Average power ='s 252rwkw

EDIT: Given that my cams are still stock (so far :P ) I'm very happy the bulk of the power is btw 3,500 to 6,500. We all know rev's are far less kind on a motor than boost (providing the tuning is good).

A nice set of Tomei VCT friendly Poncams should just about do it.

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
