That'll be interesting with 12psi - very nice!

I thought that a manual Soarer dyno run in 4th gear was 1:1 and accurate to the dyno software, but a 3rd Gear run in an Auto isn't exactly 1:1, it's more like .93xxx:1 and the figures are slightly lower on an auto.

The auto 3rd gear is also 1:1
And it doesn't matter whether they run the dyno with the car in 3rd or 4th, the software corrects the figure and you should get the same power within a % or two.

You can't run on the dyno in 4th on an auto soarer as you'll get overspeed error on a dyno dynamics dyno. Any thing over 200km/h gives overspeed error, its also not good for the dyno. 3rd gear is perfect.

Yeah, but Neil has a blower, when you fit one of those you will most definitely get ahead.

Brett, with 231rwkw what MPH does your car pull down the strip? That's a good indication to see if your dyno result was a happy one or not. I'm only saying this as it sounds quite high for a charged V8, I'm not trying to be a cnut, just want to see how accurate it is.

230rwkw from a blown V8 should mean 107mph runs!

Brett's using a centrifugal supercharger which is better at producing power at high RPM than a positive displacement blower.

Thanks Damien that is exactly right.

Maurice I am hoping to get down the 1/4 when everything is in place. I have also purchased a speed delimiter which I should be installing in a couple of weeks which I hope will help near the finish line. My last dyno result drops right off when the speed gets to about 174kph - although I'm not sure if this drop off was speed related.

Hey Maurice any V8 dyno over 200 is a happy result!

My last dyno was at the GC last November when we had a soarer dyno day at Hi Torque performance.

Is there any Benefit by getting your car Dynoed in 3rd gear instead of 2nd? Every time my car has been dynoed it is in 2nd gear. As this is how the DYno Dynamics peoples recommend the Auto Soarer to be dynoed?

I might get it re dyno'ed in 3rd gear just to see if there is any difference.

Refer to the above, but replace 3rd or 4th (refering to manual) with 2nd or 3rd (refering to auto)

The dyno software makes an assumption as to what your gear ratio is depending on the input. There's know way it can know unless you know and can manually enter it in. Again why dyno's are just tuning tools and only good for comparison when everyone uses the same gear and same dyno.

For example, 6 speed Ford Typhoon at dyno day. Did a run in 4h gear and scored 241rwkw. Then did a run in 5th gear (closest to 1:1) and scored 224rwkw. Dyno was adjusted, but the result is out by 17rwkw.

Thats using a $78,000 dynometer.

I've heard of a few similar issues with high power, high torque cars.

Solution was to strap it down harder, and they got the same result within a few kW the 2nd time around.

Brett, they were great tyres at that time ( Forget what they were )
I tried some others in Melb..They were sh1t. ( so I gave them to Bob to waste at a hill climb this weekend )

Standard practice is to use the 1:1 gear (which is usually one down from top), BUT.... the Soarer 'box cannot be locked in 3rd (1:1) and will change down to 2nd on the rollers. It can, however, be locked in 2nd (PWR and "2").

I've mentioned this before, but I don't know of anyone who has tried it. The transmission diagnostics section in the SC manual (Soarer Bible) talks about unplugging the electrics from the auto box and driving around, shifting manually. Would that be a way of dynoing the car in 3rd?

Alternatively -- Suprastick or similar.
