Dyno Day in Melbourne - details first post

[Jake F6]

I just found out that shootout mode gives 10% higher readings than normal mode.

So the XR6T Manulas that got 202-210 were really 180-189 (Motor magazine got 185 for a manual.

They got 225 for a GT) This also suggests that the 252 GT on the day was a real figure of 226 which again is correct. The two 290 Utes that made 230, obviously need more Km's on them to make the same output.

My car made 142 which is a real figure of 128. This multiplied by 1.34 (for manual) gives flywheel 172, which is exactly what Ford quotes for my car.

In short, shootout readouts should be multiplied by .9 to compare with cars run in 'normal' mode.

not quiet right ... the shootout mode is generally about 5-6% higher than non shootout modes ....

but the good thing about it is ... that it is repeatable any day and any time ... and if the machines are properly calibrated ... the same on any dynodynamics dyno ...

in no shoot out ... I've had variations of 20rwkw .. due only to the humidity, temperature and barometric pressure ... on the same dyno ...

another interesting figure is the rear wheel to fly wheel conversion ... 1.3 to 1.4 is reasonable

lastly, and this is 2c worth, most of the published figures in mags etc .. don't say shootout or whatever .... so it can be hard to compare...and shootout is going to be the likely standard as it is a dynodynamic product which is being pushed hard ...

tried to make a table ... but couldn't format it

can you see what I see ?? :D B) makes more sense now ...

Would it involve much to add a column for A/C on or off BLKXRT?

a/c are turned off .... Mark sometimes remembers to turn them back on again .... :D

it's gone ... oh well ... maybe I can say it was all in Dave's imagination B)

[Mondie]

Seems to be a reasonable spread of boost from a range of standard cars, varying between 4.5-6.5 lbs if l am reading it right. The cars finished pretty consistently in order of their boost too, not suprising.

Wonder how that could be so?

interestingly enough it looks like the guys making the least power are using ULP only. It looks like the extra $ spent on premium or the 98 octane stuff id well worth it.
