200: Corsa VXR v Clio 200

On a graph, you look at the area under the line. The more you have under the line, the more poke the car has at any given point. That's a way I was told to understand them and it's very simple. For example, compare a 197 and VXR rolling road graph (using the same scale increments) at say 3000RPM and the VXR will have a lot more "under the line" than the 197 will. So if you were in the cars and in the same gear (or as close as you could be the same ratios at least) and both at 3000RPM and put your foot down then the VXR would pull away. I hope that makes sense, if you look past the first graph on Google and see one with decent scales for a VXR and the same for a Clio then you'll see exactly what I mean then and what others have been trying to explain too.

Found 2 more videos on my HDD and combined them into one.

As you can see - Corsa is NOT pulling away. And now, with the Clio 200 gearbox, I have an even faster car in the rolling start that I had in 2009. This Corsa in the video has/had an intake/exhaust and a remap.

I will try and find another one willing to race now and see the difference.


However, I do understand what you're saying Willis - I have that "problem" with my friends Polo 1.8T GTI.
We have more or less the same PEAK bhp but the difference @ 4krpm is stunning and he starts pulling away immediately. Here is our old dyno (at the same day):

And here's how it looks now (he installed a bigger IC in the meanwhile and now there isn't any loss of power at high revs because of the intake temperature):

He is MUCH faster and has <10bhp (didn't do dyno with the IC) more and ~40kg less (has an LPG installation too) than my Clio.

Be careful for the anti-street racing crew on here by the way...
