356mm front, 343mm rears...

Ben: I'll take some decent pics of the wheels tomorrow... Had LOTS of requests for them, but haven't really had an opportunity to take any.

No full floating/strap drive?

They are floating discs...

Strap drives are for road cars. They can result in warping when subjected to high temperatures...

Bobbin heads are much more suited to race applications, going by the many brake specialists who I spoke to...

Ah, my bad, couldn't tell from the pics I assumed they were fixed/solid mounted.

Have only seen strap drive in the AP range, quite a few GTR's here in VIC run them.

Then again there are no hardcore race GTR's down here.. :P

Have you decided on what pads you're going to use?

Yah, Strap Drive is an AP Racing innovation... Supposedly cheaper than the traditional Bobbin Head fixtures, but as I mentioned, more suited to road applications than high temperature track/race applications.

I'm no race engineer, and I can only really go by what I'm told... Which is why I seek out multiple opinions and reconcile data to make sure people aren't feeding me bullsh1t ;) But it isn't a foolproof method, so I'm more than open to what people on SAU think!

Using Ferrodo DS3000 front and rear at the moment... I'm sure that I'll be massively rear biased at it stands, so will play with pad setup and brake bias to fix it.

I've got the same brake setup, but different brand. Have found that Pagid RS14's up front and Hawk HP Plus at the back work a treat - car is very well balanced under brakes. I found the DS3000's burnt up in 3 or 4 events. I'm getting 6+ events on the pagids, and have just changed the rears after 24 events.

Brilliant... Thanks heaps for that feedback mate!

Yeah, I used DS3000s in a previous GTR which I also gifted with CP5555 pistons, and they did wear out quite quickly.

I've heard good things about Hawk HT10 pads as well...

Andrew,

What time you leaving our area tomorrow morning mate?

Andy and I are meeting near Longueville Rd around 6:50am

I'm not planning on leaving that early mate :P I'll leave at about 7:30am I think... No rush to get there ;)

Performance Friction did it first, AP copied and called it a different name :P

Race cars dont have the same problems as they went to carbon rotors (typically) which dont have the expansion issues of steel rotors. In classes where they are forced to still run steel rotors you will find that manufacturers all run different types of floating hats

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
