Sup Req's here:

Saturday is non-timed practise. I expect you to get HEAPS of track time since its Grand Final Day.

Sunday is full noise sprints.

G'day Andrew....

I'm moving back to Adelaide shortly, and would love to take the drive in the GT-R to Vic and PI sometime later in the year, or early new year....

is there anything coming up (SAU) that would be worth putting in the diary?

cheers!

Ben

Hey Ben - pretty much after Oct 23 (Maserati Dat @ Sandown) the racing calander comes to an end for the year and nothing much is on until the new season starts Feb 2006.

Be great to see your car down here though one day!

Ben,

Vic seems to run a little different to NSW. Winton has a practise day most Fridays and Calder most Wed but none of us really attended them because Calders practise days have dumb requirements (full race suit etc) and Winton is miles away.

Sandown doesnt have any practise days available and Phillip Island only has them Available on the Saturday of these PIARC weekends of which this is the last one for the year.

As a rule track days for us revolved around WRX Club sprints - which do offer "driver training - which is a non timed session with an instructor" or we tend to also attend PIARC as its the best track in Oz and Merserati Club events (which there is only 2 a year @ Sandown).

So really as I mentioned the Vic GTR's will be out:

Sept 24/25 for PIARC @ Phillip Island

Oct 8th for WRX Club @ Calder

Oct 23rd for Maserati @ Sandown

And that will be it until Feb next year I expect.

Oh - except for DECA Shepparton on Sat Novemeber 19th - but thats a motokhana event.

Cheers

    • Yeah nice idea, you mean to suction it to the gauges? I hadn't thought of that.
    • A few suggestions: Do you have the option of retarding your exhaust cam gear to bring the power band over to the left? VCT would be turned off after you make peak torque, you see the power/torque will decay faster with it left on all the way to the limiter Once VCT is turned off, you'll find the motor will take a bit more timing being ramped in Send its mum, more boost! Of course, depends on your exhaust pressure.
    • Tow a boat... people won't know wtf is going on 🤣 
    • I was back on the dyno again yesterday after completely revamping my methanol injection system. I was making 440kw at 19psi. Great, this is more then I was making last summer with my old meth system at that pressure, and I figured it would be smooth sailing up to 30+psi. We continued increasing from there and by 25psi, I had only hit 455kw. Dyno sadly lost utility power at this point and I left. We seemed to be on course to hit the same power wall as last summer (477kw@27psi). This is a built RB25 S1 stroked to a 2.8. Built and ported head with Kelford 272/262 cams. Precision 6466 Turbo. Tuner last year believed the power wall is a mix of RPM limitations (Hydro lifters/Limit set at 7600RPM) and fueling. With my new meth system, we're seeing zero knock now but it still won't go up.  What else can I do at this point? Here's my train of thought.  - It's clear from the dyno graph that I would easily make power to 8500+RPM but I'm limited to 7600RPM. I could risk increasing my limiter, but hydro lifters have me worried. What are my options here besides going NEO head or solid lifter conversion? I'm rocking a 1.05AR turbine on my 6466. Would dropping down to a .84 help shift that power down in anyway? - We're only seeing roughly a 30kw difference at the top end with VCT on or off. Is this normal? I want to confirm VCT is working properly. - Should I look into other cam options?  - Should I just keep increasing boost and see if she wakes up later on? I would expect to hit 600rwkw around 35psi with my 6466.
