Did some tuning over the weekend. sorted a boost leak that made a bad noise at 17+ psi. After going over the logs from friday night, the car makes 16psi at 4000rpm. I've upped the boost to 19psi, but havn't done and tuning or logging on it yet.

Damo wasn't able to drive the car for more tuning today, so i knocked up a heatshield to keep the inlet cool

Should have the tuning finished this week, and then it's off to it's first supersprint on sunday

Well the car got it's first run on the track this weekend. I was pretty happy with how it went, only problem was a pertty bad shudder though the steering wheel after the brakes heated up, i'm hoping it's just the pads going through there first heat cycle. They are Endless ccx that came with the calipers, and from a quick glance at the net, other people have had the same problem with the stoptech/ccx combo. I recon I'll put some hawks into them.

The car is very easy to drive, and we only just touched the surface of the shock tuning, the rebound is still at full soft. The car was still getting .5 sec a lap faster with each change. Ended up the day with a 62.8. Always fun when people come and basicly call you a lier when you tell them it's a standard wrecker rb20, with a rb20 highflow.

I will put some video on the tubes tonight, and upload some of Damo's artsy pics

the washer bottle is the temp catch tank.

no idea on power, only dyno it's been near is the arse dyno, asit was all road tuned. It's running 16psi boost at the moment...might need to turn it up some more though

Don't you just love it. Its a good feeling when you exceed peoples expectations with a humble, maligned RB20 :)

Re the brakes , CCX are good things but perhaps they are too hard on rotors. I have used only one set and loved them but they did seem to have an appetite for rotors with regards to shudder and cracking. I will be trialling the PFC 06 pads with the Stoptechs and 343mm rotors. I am really happy with how they have all come up. I will try and get a set of DS3000s to trial back to back with the PFC06 before they get too worn

Any Vids/pics yet?

Nice vid. How fast was your GTR around SP?

Best I got was a 60.9. But as you can see it's all about HP, and the GT-R was up 10-15km/h at the end of the straights, and cause of the brake problem was a braking 35-50m earlier than a was in the GT-R.

In the Targa N1 the last time I drive it, it was in 2009 trim, and I got a 60.3. But 2010 trim was about 50rwkw more.

    • Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.         
    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.
