I can see the pic so you've got it sorted.
Anyway, looks to me like as the torque comes up you get to the peak and the wheels start spinning on the rollers, that's why it's levelled off with wavy lines.
The good part is that it'll be making more than 420 horses.
You'll be going back again?
Yes I can see his latest post with the chart but still can't see previous two posts with attachment. anyway I'm not being negative Steve but he said it was an older dyno either 2002 or 2004. If he tunes his own cars on it at 450 hp and 650 hp and I saw another picture of an R33 on the wall with a big thanks written on it - and I race that car- I asked the hp of that one and he said 550. So he must be right in that his Dyno has this quirk. I also notice on my latest chart above, that peak Torque is stated as much higher than the graphed Tq line???
Anyway tip for anybody that gets Dyno work done. reset your trip meter so that you know how many kms it did during dynoing. this one did 40 kilometres and used a quarter a tank of gas, still got the 75l tank, which seems to equate. I hope I get further than Mike Tall did in the Nevis 1200 yesterday on TV. he wound the boost up and detonated it within 10 metres from the start line!. Will I be going back- hopefully not, the car is definitely idling and revving from a cold start better so maybe the IAT is an improvement. I haven't got any events in the next few months- they have all been cancelled because of the plague. I have been told of another tuner/dyno shop elsewhere that is supposed to be an excellent tuner so that may factor into my future. So here I am pondering my next move. Race car testing day or consolidate/refine brake pedal setup or bite the bullet and do any of these three things. 1. alter rear turbo air intake as advised by tuner. he doesn't like the 1.3 metres of flexi pipe feeding it, said they don't like sucking through long tubes.2. redo the FMIC by turning it upside down and shortening/altering position of I/C pipes in and out of it to a high level thus freeing up space for better oil cooler position and potential gearbox oil cooler.3. drop out rear subframe and swiss cheese it (within the stated rules of Motorsport) for weight reduction. Or do I paint the house?
