Hi,
I'm somewhat reluctantly advertising my Westfield for sale. I've admitted to myself that I want to dip my toe in to the world of BEC's.
It was built by a fairly wealthy retired chap in 2010 who had something of a 'gentleman racer' fantasy with the idea that he'd have a car that he could drive to the track, race and then subsequently drive home. As far as I know that idea remained something of a fantasy throughout his ownership, it never saw a starting line but he did build a really good car. Four years ago I wasn't really looking to buy a Westfield, just casually browsing the forum and stumbled across an advert for this car, once I'd viewed it, I realised it was too well built to miss out on and ended up buying it.
The car is built on a 2010 Aerorace chassis power by a Zetec blacktop that was brand new at build date, the most recent rolling road graph I have shows 232bhp at the flywheel and 212bhp at the wheels
Full Specification
2010 Aerorace chassis with removable rear arches (chassis marginally lighter and stiffer than the road chassis of the same period) fully road legal and the same dimensions as the standard SEIW.
11000 miles
It has an MOT for another 9 months.
Black bodywork with carbon front arches, in very good but not unmarked condition.
In that spec at the last setup session with about 1/2 tank of fuel it weighed just under to 572g.
Engine
Built in 2010 with new Zetec Blacktop
Head ported and polished by CNC heads and matched with their specification cam. Following this link ( http://www.cncheads.co.uk/?p=755 ) takes you to the website the tuner provides on this head and cam combination for more info, extrapolating the power claims CNC make ( 215bhp @ 6400rpm and 247 bhp @ 8200rpm) to the 7500rpm limit on this car fairly accurately supports the claimed power output on this engine.
Arrow engineering buckets
ARP rod bolts
Balanced and polished crank
Standard Zetec flywheel machined and lightened by CNC Heads
Raceline sump
Omex 600 ECU
Jenvey throttle bodies
Bosch green injectors
Simpson Race Exhausts aluminium manifold 4 into 2 into 1 ( http://simpsonraceexhausts.com/manifolds/ )
Westfield carbon silencer
Bespoke breathers all feeding into aluminium catch tank in the nose cone, although very little oil ever gets blown into the tank.
Most importantly lots of time and effort spent mapping the engine. Despite it's relatively high state of tune it starts easily hot or cold, idles nicely and is generally very drivable and tractable with no grumpiness or nasty flat spots. In the interest of longevity the limiter is set at 7500 rpm at which point the power curve is still climbing. It also makes some lovely burbles and pops on the overrun.
Centroid fuel sender which gives a better accurate fuel level reading.
Cooling
NEW black Aluminium race radiator from Radtec with 60mm core and Aerorace ducting ( http://radtec.co.uk/products/331/Vauxall-Ford-Cosworth.htm )
Custom pipe work and thermostat housing which ensures this car never has the cooling issues some Zetec Westfield suffer from, coolant temp is rock solid in both traffic and in hard use on track
Drivetrain
Helix fast road clutch
Rebuilt Sierra 3.92 LSD, no clunks or play and locks up nicely but not too aggressively. I actually prefer this diff to the ATB I had in a previous car, although it's not quite as tight at slow speeds for 1st gear sillyness that seems to result in it never 'pushing' the car into understeer in faster corners on track. I therefore prefer the way the car drives in comparison to car with a tighter diff, however it wouldn't be as useful in an autocross type scenario.
BGH E8 type 9 gearbox. Ratios and price listed in the following link, this is the strongest and most expensive 'box BGP supply ( http://www.bghgeartech.co.uk/html/5_speed.html ). The ratios suit the engine very well with a usefully long first and 5th geared to a theoretical max of about 140mph. (Ratios are 2.66/1.75/1.26/1.00/0.86)
Chassis
Standard Aerorace chassis with associated extra bracing in comparison to same era road chassis, this car does not have lowered floors.
Protech single adjustable shocks valved and setup by Procomp in Birmingham along with a full geometry setup, car runs with a reasonable amount of negative camber and some toe out at the front which gives a pretty sharp turn it, understeer isn't really something it understands!
Anti roll bars are fitted to the front and rear
13 inch Compomotive CXR wheels in black with nearly new medium compound Toyo R888R in 205/50/13.
Rallydesign Quickrack and sort steering arms fitted. Unlike some of the so called 'quickrack' setups I've seen this gives a real two turns lock to lock with the arches almost touching the tub on both sides on full lock, ie it's a genuine quick rack, not the version Westfield sell which is far from it and gives a terrible turning circle.
Westfield alloy uprights both front and rear.
Westfield widetrack front wishbones.
Rapfix quick release steering boss has been fitted with a momo suede Mod.26 wheel
Braking is a full AP racing setup including master cylinder and front and rear callipers. Fitted with Ferodo DS2500 pads and a brake bias adjuster.
The car (in my opinion) drives beautifully, it's pointy, intuitive and hugely predictable but the setup is still relatively soft which means it's eminently useable as a road car with sensible ground clearance and great compliance while still being blisteringly quick on track.

I'm sure there's something I've missed but that's hopefully the important stuff.
It's got a great spec and, much more importantly, it's been really carefully built by someone who knew what they were doing and had both the time and cash available to do the job properly. I don't have to sell it and know that replacing it with a car of the same standard will be difficult.
Thanks for reading,,
Nick
