Rolling Road Day @ Surrey RR, 18th July
Would but my car has no MOT so can't get it there even though it is sooooo close at TGT's place.

Big thanks for Toxo for inviting us and Dave from IMOC for organising the day. Gord, myself and Wozza managed to run right near the start of the day. I will post photos and a video later, but right now here are my dyno graphs.
I got 153.9 bhp at the flywheel and 120.7 bhp at the wheels. Peak torque looks to be about 143 lb/ft. Pretty happy with that since the spec figure is 153 bhp and 144 lb/ft, and I've done nothing to the car to help bhp other than (possibly) the K&N filter and IK20 plugs, and the car is nearly 10 years old :thumbup:
Looks like there's a slight ramp-up in power at 4400 rpm. I suspect that this is the valve in the inlet manifold opening to change the shape/length of that manifold, rather than the VVT-i (since the VVT-i is more of a continuous effect rather than an on/off thing), though this is just my own guess.

I did take a video of my car on the dyno, but haven't bothered uploading it and posting it, since it's a bit boring really. All you can really hear is the noise of the cooling fan.
Anyway, here be some pics :
