For US Spec, curb weight includes all fluid, oil gas etc. Japan spec is dry weight without all the fluids. Europe spec might be same as Japn spec

btw, the weight of the FQ model was measured at a vehicle balance/scale.

On this plot, which chart is what turbo.

Nice info. How does the Gtech know the engine RPM, is there a tach input or somethign on it? I'm sure you know also that your curves will be very affected by the the outside air temps and winds etc, so it can be difficult to compare runs on different days

Great info, thanks for sharing. I didn't know that the G-Tech had dyno plotting software, great stuff.

The SS version will allow you to look at dyno plots and other stuff on the GTech screen, but the RR allows you to import it onto a laptop.

Would be nice if you could post up some in-gear acceleration numbers at various speeds, e.g. 30-50 mph, 40-60 mph, 50-80 mph.

I have only done third gear pulls for dyno runs. The only good number I have, is the 60-80mph, which was done in 1.83 sec. w/ the RX6 turbo @ 27psi. The GT3076 @30psi was around 1.89 sec, but I am not 100% sure on that one since my laptop, w/ the GTech software, screen died.
