1998 Westfield SEW Aerorace, 530kgs, 221bhp SOLD

[B.RAD]

1998 Westfield SEW Aerorace - road going competitive sprint, hillclimb and trackday car

 

A rare opportunity to buy a fully developed, competition ready Westfield that is also fully road going and a pleasure to drive.  You can bimble along the roads at 3,000 rpm with the exhaust popping and crackling, or you can go to any track day and be the fastest car there, or turn up to a competitive sprint or hillclimb event and win.

 

Lightweight Aerorace chassis built in 1998, fully stripped and rebuilt in 2015. Chassis is 10% lighter than standard and comes with additional bracing throughout.

Road registered with 12 months MOT

MSA logbooked (enables the car to compete on list 1C tyres if desired)

 

Recent racing achievements:

Protech shocks all round (new in 2015) with 175lb rear springs and 300lb front springs (spare set of brand new 275lb and 150lb springs included if you'd like to go softer but the current set up feels right to me)

Playskool soft front anti-roll bar on CleaR Motorsport easy adjust fittings

Quick steering rack (2.4)

Alloy hubs (saves 4kgs over standard)

 

Rear axle - removed 2015, refurbished and straightened by Mallock (common issue is the axle bends fractionally when the trailing arm tabs are welded on), also had a touch of toe in added

New 3JD NXG LSD with 30/90 ramp angles

Quaife quick shift

Lightweight flywheel

Engine - this is where the real heart of this car is.

Vauxhall C20XE, built from bare block in 2016, covered less than 500 miles

SBD Omega Pistons

SBD Steel rods with ARP 2000 bolts

Early crank (crank, flywheel and clutch balanced together)

Internal trigger wheel removed with SBD external trigger wheel and sensor

SBD vernier pulleys

Solid lifters

Titanium spring caps

Jenvey taper throttle bodies with 90mm ram air trumpets

Pipercross air filter with bonnet cut for cold air

MBE 967E ecu

Revotec electronically controlled high power 'pull' fan and polo radiator with ducting (maintains temperature perfectly in all situations)

 

Simpson Race Exhausts custom made bonnet exit exhaust with 7" can (averages 95db static, no issue at any circuit attended including Bedford)

 

Engine produces a solid and reliable (these are the two elements the engine was designed for and where the cost is) 221bhp and 176lb/ft torque, mapped at Track n Road. It will rev up to 9000rpm, however I have had the hard cut limiter set at 8200rpm and never gone beyond this. As peak power is made at 7000 rpm and holds all the way to the red line, I have tended to short shift at around 7500 rpm.

 

A change of cams to QED 450V or SBD's next level up will see well over 250bhp, similar spec engines comfortably run 280bhp so the option is there for you.  Given the weight of the car I have never felt the need for more power, preferring the reliability and strength offered as is.

 

Lightweight lithium ion race battery (weighs 600grams)

 

Raceleda alloy calipers with Ferodo DS1.11 pads

Twin brake cylinders with pedal bias bar

Floor mounted pedal set

Throttle pedal modified for perfect heel and toe positioning

Additional spares available at asking price:

Spare nosecone

Two spare bonnets, one standard weight already cut to fit, one lightweight brand new

Spare wishbones

Spare quick rack

Spare coil packs and coil leads

Carbon effect rear arch protectors

Set of 13" Minilight alloys with slicks

Set of front springs 275lbs

Set of rear springs 150lbs

 

Optional set of 13" Compomotive CXR's in black with Kumho V700 or 13" Compomotive CXR's in gold with two event old Avon ZZR in super soft compound available to purchase separately (as shown in some pictures) 

 

I have owned the car since 2014 when it was bought with a crossflow engine.  Everything in the car has subsequently been replaced or upgraded, with a major overhaul to convert to the Vauxhall engine and ground up rebuild in 2015, followed by the installation of the race engine and dry sump setup in 2016.  The time, cost and development gone into this car is beyond value and if you're still reading, you will no doubt know that this is not your typical Westfield.

 

Included in the asking price is a corner weight session to set the car up to suit the new owner.

 

Asking price is £14,995

 

Happy to accommodate passenger rides to experience the drive but test drives will only be available on receipt of a significant non-refundable deposit.

Has this winning machine sold yet? 

[B.RAD]

Fair bit of interest and some viewings coming up. The weather hasn't been kind so had to reschedule a couple from last weekend.

[B.RAD]

Responses to a few questions from elsewhere:

Has a 20 litre fuel tank, baffled and foam cell filled.

Simpson exhaust is repackable and I have spare acoustafil that can go with the car. Measures at 96db and has passed all noise tests at every event, including track days at Bedford with no issues.

Fastest Novice awards are given to the fastest novice entrant from the entire entry list, not just Westfield competitors. I am by no means a great driver so there is still much more the car can give.

I am willing to remove the spares package and take offers for the car around £14k.

I strongly disagree with this point...

 

Anyway. Great car here, and one of the fastest "Arrive and drive" cars you can actually have without spending serious money or go to the actual only sprint focused cars and single seaters.

 

If I was on the hunt for a competition car... I would go for it without any sort of doubt.

Deposit taken

[XTR2Turbo]

well done but will be a shame to see her go.  Hope you get something else to enter speed series with again at some point

[B.RAD]

Thanks David. I'm absolutely certain that I will. Just have a few itches to scratch first! 

[Terry Everall]

will we see the Westfield back out in the speed series?

[B.RAD]

The prospective buyer seems most keen on the Javelin series, but is aware of the WSCC Speed series and the cars' eligibility for it. I don't think he is a forum member yet.

[B.RAD]

Sold. Off to its great new home tomorrow. 

[TAFKARM]

Great news! Nice weather to pick up a new toy too!

[B.RAD]

Yep, it's ideal. He's driving it back to Bristol, plenty of time to get acquainted!
