Did your astra go on different rollers to give the figures displayed in your sig?

Does the RR not take temperature and air pressure into account so there should technically be no difference.

End of the day, the car drives well on the road, but could be down to a few things

engine - egr stuck open slightly, swirl flaps etc etc but unlikely

but more than likely, as i was explaining to andy - the reason there stage 2 vxrs always make more power at thorney - they use a bigger fan. that simple

there over boost at 21psi to get the torque up, creates so much heat (pressure = heat) that the intercooler cant cool the intake charge quick enough (with totd fan) - so the ecu starts dropping igntion timing out, there for power and torque drop off in high revs at a high rate, where i bet on thorneys rollers it makes more power and holds for longer with a more flat graph.

thats why the unmapped vxr with a fmic made more power and for longer, one was demeanding so much overboost and held power higher in the revs

so it could be something as simple as that, which is more than likely as the other astra diesel didnt make the power either...

would need to do some datalogging on intake temp if ever goes on rollers again

drives more than fine on the road - which what counts at the end of the day

That VXR8 made my life.

Got pics of all cars except the Astra Coupe, which is a bit stupid seeing as it's my mate's car Was watching the screen too intently to see who had more power out of the two of us

Uploading pics now, will post in a min

Had nothing to worry about in the end, did you

Should probably add a warning here, had a bit of trouble with lens flare and exposure with cars that had headlights on so some have come out better than others.







Kept telling people I made 124bhp, turns out I was getting confused, as this pic shows:





























Stocker's car was IMMACULATE. I'm convinced he detailed it in the car park as there wasn't a spec of dust on it.







VXR8

It always feels weird after a dyno run for some reason. Seems to sort itself out by the time you get home.

Maybe it was a "driving out of character - think of the MPG" light
