ISF dyno run this week....how many kw?

Recommended Posts

I've booked my ISF in to my local dyno on Friday afternoon (Mainline dyno @ Newcastle Dyno Centre). Curious what everyone thinks it will make based off best guesses and some of you with first hand experience.

Engine related Mods:

  • AFE filter
  • HPS silicone intake pipe
  • xforce exhaust
  • gutted primary cats


Im hoping for around 260kw at the wheels which with a 20% drivetrain loss will equate to around 330kw at the crank. Considering the car came with 311kw from the factory plus the mods im assuming will be about right.

The other thing im going to do is test back-to-back whether there is any loss/gain from disabling the airbox flap so that it remains open at all times.

Curious what others think?

240 rwkw if its a Mainline dyno. Mine was 237 same mods but still had primary cats, 270 after tune, good luck.

270 after the tune for you? Which tune if you dont mind me asking? Im unsure whether to just go with the RR Racing OBD II tune (convenient, well priced and saves me having to drive 2.5hrs to get custom tuned) or go see Autowerks for a custom tune. Id really like some more low end power and a few extra hundred RPM up top would be great too.

Yep autowerks but they stuffed the tune (car went into full limp mode no power had to truck it back and they only payed for half the cost not impressed ) go RR they are the people that cracked the ECU in the first place, in hindsight I would have gone RR 7200 red line would be nice, and it looks very easy to load cheers.PS RR tune is half the price. Someone on here went full RR tune intake etc. and got very good results

Well the car was very consistent (all 4x runs were within 3kw of each other) and there was no difference in power/torque delivery by keeping the active airbox open. The best run today was 249kw.

Im currently researching tunes and will be getting the car re-dyno'd at the same place once tuned to see the different. Hopefully 20-30kw more after the tune and some stronger mid-range.

Its the scale he used on the graph that exaggerrates the torque dropping off at high RPM.

The dyno operator said he had issues with the car wheelspinning on the dyno so he had to feed the throttle on rather than just mash it.

If he’s got spin with 250kw he’s not strapping it down correctly, feeding the throttle sounds like a bs excuse

Faaaaaark he was so impressed with RR etc, and then bang, so hard when its overseas product and not individually dyno tuned. Personally would not do it.

I thought the gearbox went bang not the motor after all he was at a track flogging the date out of it, please correct me if I'm wrong.

You cant blame the tune as the sole issue when the car had 120,000kms on it and they guy flogs the heck out of it at the track on a regular basis. Do we know if the car had any previous or existing issues/faults? 

I have a sneaky suspicion that something else was at play with that particular car.

It all seems shady as lol, had a warning light for the auto also... I guess we will have to wait and see after it’s been diagnosed. My guess it’s run lean
