i didn't hear nathans car pinging its date off, i did hear/see it wheel spin excessivly tho..

the was a fair amount of tyre smoke after the first run..

can anyone, ant hopefully confirm what gear they did the runs in, because his and nathans cars seem to come on very hard and very fast, a lot faster than i expected..

or is it just possible the new formax guy running the dyno, got the ramp rates wrong?..

I saw someone mouthing "fourth" when they had one of the GTRs on the dyno ... can't remember which one it was though ...

Yes denver, the ramp rates were definetly wrong (either to low or high i dont know i dont know much about controlling a dyno) from what ant was saying to me, if u look at the graphs from both cars the power and torque lines are extremely short, which indicates the car reving to quick. Steve said they were know where near the 126 (*edit) they use in shootout mode

Both cars were definately done in fourth, but the ramp rates were around the 170-180's, which is way off the 100 they use in shootout mode. God only know's why Formaz chose ramp rates like that. The ramp rates for both Ant's and Nathans were very similar and didn't cause the difference in power, but I don't think either were strapped down anywhere near enough.

Still, everyone was dyno'd on the same day, under the same hot conditions ... Ant got 600-odd horsepower, Nathan got 475-odd ... well done to the both of them, it's still a shitload of power.

But, lets not bring on the excuses ... it's like the drags

The first 10 is all that matters.

Anyway Ant won and proves the new Wolf GTR plugin ECU with 6 ign drivers has the edge with more to come.Shootout uses 126 ramp rates and using 180 looses power in turbo cars but both Rs had the same rates.

The main problem with Nathans tune is the Dyno used for tuning reads craze power and has very quick ramping ( I have used it and can't get the boost on like other dynos)

    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
    • 1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
