Great site detailing locations, features and ratings of rolling roads and engine dynos across the UK. With user ratings and comments. Well worth bookmarking -

Progress of sorts - stickered up, drove it hard, got muddy, cleaned it. Knackered now…

Not to plan really, Motec wouldn’t talk to laptop so running with a bit of overboost, shaking out some naily connections in the engine bay none of this helped by me comprehensively beaching the car in the gravel in the first session…

Anyways, due to popular demand, here you go, comment yourselves out -

So, it was off to the Racing Line in Halifax to get the Group N car setup. Quite a few things to sort on it and in the end the quite a few things turned into a massive amount of things, Matt at the Racing Line proving patient, knowledgeable and (it needs to be said again) patient!

The first hurdle proving to be the Motec M48 installed, after a bit of headscratching it appear there are various versions of the M48, some older than others… this one being one of the older ones, so ensues fuckeries, short end of which is handmaking a comms cable onto the board itself!

Anyways, five days later we have -

• fixed comms lead in glove box
• Motec boost control solenoid
• Motec MAP sensor
• uprated fuel pump
• new fuel filter, plugs, etc
• nasty up the antilag a little

The car was mapped for both BP Ultimate (road running, cheap days out) and the more usual VP109 race fuel (stages, testing). The first image below shows just how much a 32mm Group N restrictor strangles the car, a measly 240bhp and 250ft/lbs of torque. Most of this was at 1bar of boost, further boost not making much difference whatsoever.

Then we move onto VP109, here we get up to a closer to normal 273bhp but the whopping 320ft/lbs of torque should prove fun. While not up to works Group N figures (and yet we wouldn’t expect that) it should prove entertaining, not least because the car should be light, very light. The graphs below show the torque curve and then the boost used. Just shows the difference a proper fuel can make!

Going to 1.4bar on a standard turbo… well, at least I bought a spare… along with 320ft/lbs through a standard box.. again, at least I have a spare…

Good friend, WRC mechanic, codriver for Rally Barbados 2006 and general all round drunkard Damian ‘Logic’ Yearwood took these shots on a visit to Prodrive…
