He went with a 6466 T4 divided 0.84 so I'll wait to see his results and then decide on what I do.

Interesting point i just saw is that the 6262 is rated at 705hp, the 6266 at 735hp and the 6466 at 900hp!! Damn that is a massive jump from a 2mm bigger compressor wheel and additional blade.

Most of the Emo and Rexxy boys think the 6466 spools very similar to the 6266 but makes a lot more power. That really doesn't make sense from Precisions point of view. In any case, it seems the choice might come down to 6262 or the 6466 - the 6466 is one big turbo for a track car....

That is just crazy, man! Nice work :) Was the 6766 totally maxed out?

Thanks mate, hmmm not convinced yet, I will give you an answer when I'm done with this one. 6766 will go back on next with a slightly bigger housing to see what they can do.

as usual..i tip my hat to you P.J, track looked good for running numbers!

cheers

Thanks Darren! Yes track was killer but suspension still far from ideal, 1.40 60 on the 8.9!

Congrats man, that's massive.

What power/boost was that at?

Cheers John, 44psi, no idea on power. Given that it made 636kW at the wheels on 42psi, I would say in the 650kW region.

I was thinking about getting a Precision PT6262 for my RB26/30, have had a look on eBay $1137.28 delivered and Powertune Australia looks to have dropped their prices to$1150, only $13 difference so i ordered through Powertune Australia as they have warranty for the turbos as well as the support! I am excited and can't wait to test this baby out!! :)

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
