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)

      Good to see your rotors appear as rusty as mine šŸ¤Ŗ

      Took it for a drive to do some logs, Iā€™m pretty sure my voltage issues and electrical noise issues are gone, Iā€™ve sent a log to Adam and am waiting to hear back with confirmationĀ  att.K23U9eHyiEJxixH6y1__GQfuqK0EgIoDgQFTs9G8x_w.mp4 Ā  idle video from that day just becauseĀ

      Went looking at mine, reading off the tyre, presumably these are 1st week of 2003. Still hold air (I haven't had to pump them up in over 12 months!) Ā  Ā  I couldn't quickly find the date on the front tyres, they were fitted around 2008 to the rims, so probably not quite as old, but they have a lot more dry rot cracks in them. Still hold air.

      I am now intrigued to go check the dates on the tyres on my Skyline... We need a game of who has the oldest tyre still holding a car up, and successfully holding air (for longer than a 2 weeks I feel is successful air holding). Ā  I feel your tyres may be beating mine

      Ok, still waiting for a date to get the cams installed on the MX5, why so long, because MX5 Mania has received a few new sets of different cams with different specs for the MZR and are currently trialling them, and working out what is best for 2.5 "powers" with stock internals, in the end if I go bigger than the Kelford stage 1 cams I'll need to look at the valve springsĀ  Hopefully I'll get the news on them next week As for the boot of the car getting fixed, I hopefully pick it up early next week, I was sweating on picking it up yesterday but, meh, it was not to be, so ne weekend cruising for me
