ANDREW AND DEAN HOULT - SUNBEAM ALPINE

A complete turnkey car by CIRC, Andrew and Dean Hoult's Alpine runs a 429ci big-block Ford with C6 trans, a street roadster style 8.50 tagged chassis, and is fully street legal.  Shown above waiting for its MOT, with 500hp and an all-up weight of about a ton, the car is quite lively on the road when full throttle is used!  The brothers intend to enjoy their car on the road for a while, though a track debut in 2010 is planned.

 
TREVOR WILLIAMSON - MK2 CORTINA

Trevor is building his street/strip/trackday Cortina himself with guidance from CIRC, but decided to have the front suspension built by us as a complete unit.  The chassis rails are represented here by the sides of the black rectangle.

As this car is to go round corners too, it was decided to fabricate everything, including the uprights, so that all the geometry could be controlled in the design phase.  This suspension features very shallow kingpin angle and 4 deg of caster, for minimal cornerweight and camber changes during steering input, 20% anti-dive geometry, and a low roll centre to match the CIRC-designed triangulated 4-link setup at the rear.  The car will eventually run LS2 smallblock power.

 
MATT DAINTY - VW BEETLE

Completed in Jan 2009, this is a fairly standard CIRC VW rollcage in chrome-moly, using our technique of mounting the cage to both the heater channels and the floorpan, greatly increasing the effectiveness of the structure.

 
STEVE & ADELE WOODBRIDGE - VW BEETLE

Longtime race car crewmembers, 'the Woodys' are going racing with their oval window VW.  This car has been constructed a little differently to most other Volkswagens, having a funny car cage and twin aluminium seats built in.  A 230hp motor should see the car well into Outlaw Flat Four territory, along with forays into Pro ET and Comp Eliminator.

The 'almost finished' car debuted at the Volksword Show in March 2009, taking a Top 20 award.


MARK PASCOE - VW BEETLE

 

Another Beetle, this one also a little bit different.  In this case, Mark has chosen to cut out the factory steel front and rear bulkheads to save weight.  This has necessitated continuing the chrome-moly rollcage to the rear shock absorber towers at the rear, and to the beam axle mounts at the front, to retain the required structural rigidity.  The front of the frame assembly also mounts the fuel cell.

The new bulkheads are fabricated from aluminium, the rear firewall being dzus-fastened in place for easy removal for maintenance.  Mark hopes to run in Outlaw Flat Four competition.


STEVE NASH & MICK FRANKLIN - MERCURY COUGAR


'Splinter' took his proven ICE-built twin-turbo Ford motor and commissioned CIRC to build a new, lightweight Street Eliminator contender around the potent powerplant and a Team Wildcat constructed fibreglass Cougar body.  The chrome-moly frame was the first SFI 25.2 spec chassis built in the UK, and the suspension, weight distribution and vehicle dynamics specifically designed for street-legal tyres (CIRC pioneered the use in the UK of the Strange long-travel GT struts on this Cougar, now seen on one or two other Street Eliminator cars).  Emerging from the CIRC shop in early 2007, Team Wildcat took the hard-fought Street Eliminator championship, and the class ET record, in their debut season with the new car.

 
JOHN HOYES - FORD POP

John's street and strip Pop runs an unusual supercharged, Wildcat-headed 5.3 litre Rover motor backed with a 5-speed Tremec manual transmission, coupled to the engine with an SFI spec steel bellhousing and a CIRC-made adapter plate.  The brake and clutch master cylinders are hidden beneath the floor and will utilize remote fluid reservoirs for easy access.  CIRC were responsible for the 8.50 tagged tube frame plus all the tinwork and other fabrication seen in these photos, and the Pop is now back in John's workshop for finishing.




JOHN DEWEY - '57 CHEVY

Out of the shop a while back and now finished, this ground-hugging 57 is inspired by the fast street cars seen in the USA. 
Featuring a CIRC-built SFI 25.4 spec chassis and the first ST1200 street Lenco seen in the UK, the Chevy is has a 588ci Pontiac Big Chief motor in its engine bay.  In spite of its radical drivetrain and quality of finish (the '57 placed highly in the 'Best in Britain' category at the Doncaster Custom Show in late 2008)  John does indeed use the Chevy regularly on the road attending local cruise nights, and recently attended a Peak Performance day at Santa Pod where some 'gentle' low 10 second passes on street tyres provided an encouraging starting point.


 
LEE COHEN - FORD POP

CIRC built the chassis and suspension on Lee's Pop a few years ago, as a street/strip car with a single-carb smallblock on board.  Recently the car has been back for a series of substantial upgrades to take the 1200hp supercharged alcohol smallblock Chevy which now resides in the engine bay.  After a couple of checkout passes at Easter 2008, Lee's first proper outing at the Santa Pod Big Bang saw him gradually moving up the learning curve to a PB of 9.37 at 153, whilst later in the year an easy 8.69 at 160 showed more of the car's potential.
