Wildcat 1000i H.O. here in the UK

At last the long awaited Arctic Cat Wildcat 1000i H.O. side by side has arrived in the UK. Thorney Offroad are the first UK Arctic Cat dealer to receive shipment of these awesome vehicles and have them available now for viewing and demonstration rides.
To celebrate this fact Thorney Offroad are arranging an official launch day at their brand new Silverstone facilities. The launch date is set for Saturday 16th June and on offer will be:- 

• Tour of Thorney Motorsport race workshop and Thorney Offroad showroom
• Free BBQ
• Rides and drives on the new Arctic Cat Wildcat 1000i H.O.

There is limited availability of places so early booking is recommended.
For more information go to the Thorney Offroad website.

Gearbox Front Mount Bracket

We are making great progress towards completion of the Astra VXR engine transplant. The latest achievement is the design and manufacture of the gearbox front mount bracket. The chassis of the Corsa SRI differs from the Astra VXR is as much it doesn't have a crossmember running across the front of the engine bay. Consequently we have had to manufacture a bespoke crossmember resilient to absorb the torsional loads imparted by the 400bhp Z20 LEH engine. The final design is very innovative since, not only does it provide an anchorage point for the Astra gearbox front mount but also doubles up as an anti-roll bar, thus providing additional body stiffness. Yet again a fine example of Thorney Motorsport's engineering expertise. Once painted this crossmember / anti roll bar assembly will really look the part!

Astra VXR Engine Conversion Update

With less than 4 weeks to go to the launch for the 400bhp Astra VXR engine transplant into the Corsa SRI race car the fabrication of the new front gearbox mount bracket/cross member is under way and should be completed by 22 May. Attention is now focused on production of the full set of cold air intake and cooling silicon and rigid pipes. We intend to use black silicon hoses as well as black rigid pipes, both of which will incorporate the TMS logo. The complete set of hoses/pipes will be available to buy through Thorney Motorsport, once the engine conversion project is finished and fully tested.
We have called in the services of SFS Performance, specialists in the manufacture of motorsport silicon hoses to measure up the installation and produce the kit.

6 weeks and counting ...

Throughout this Astra VXR engine transplant project regular project review meetings have taken place with Thorney Motorsport. At the last meeting it was decided to set a target date for completion of the project so as to focus the minds of all concerned. With Thorney Motorsport competing this year in the BTCC with their Vauxhall Insignia we fixed the weekend of June 9/10 - this being the next scheduled BTCC race meeting at Oulton Park.
 The aim is to have the Corsa race car fully run-in and dyno tested with a smart new livery to do justice to the collabaration between us and Thorney Motorsport. The Corsa will be on display in the Oulton Park paddock at the TMS team garage.
Still left to do include:-

• Tidying up the various wiring harnesses
• Complete the Pipercross air intake system installation
• Installation of the Scorpian 3" full race exhaust system
• Fabrication of front gearbox mount bracket/cross member
• Dyno testing / custom mapping to achieve 400+ bhp
• Vinyl wrapping / bodywork detailing

6 weeks and counting ...

Engine management sensors - Z20LEH engine conversion

One of the main engineering challenges faced when installing the 400bhp Astra VXR engine (Z20 LEH) into our Corsa SRI race car has been the integration of the Z20 LEH engine ECU with the main Corsa ECU vehicle management system. The engineers at Thorney Motorsport have come up with an ingenious solution to this challenge which ensures the reliable and smooth running of the whole vehicle. Along the way the opportunity has been taken to incorporate several additional sensors into all areas of the vehicle management system including fuel and engine control and monitoring. These extra sensors will provide vital data output to assist with engine set up and ongoing vehicle performance monitoring.
Details of this exciting project undertaken by Thorney Motorsport can be found at our website dedicated to the Corsa SRI race car and this 400bhp Astra VXR engine transplant.

Air Intake System - Corsa Race Car

The Astra VXR engine transplant into our Corsa SRI race car is slowly moving forward. Attention has turned to the cold air intake system. We have decided to use the Pipercross Viper VFC244 sealed unit cold air intake. The unit will be tucked away down inside the nearside front wing away from the heat of the engine bay. It will draw cold air in through the nearside front fog light aperture.
Using 'velocity air force', the Viper air intake directs cold air directly into the engine. The cold air feed takes air from the area of cold, dense air straight into the Viper's inlet, swirling it through a unique Pipercross reverse-flow air filter contained within a carbon fibre heat shield, then into a ram pipe to increase the air pressure before feeding it into the induction system.
The carbon fibre heat shield protects the air charge from under bonnet heat keeping it cool -and therefore more dense -thus introducing more oxygen into the combustion mixture,giving increased power.
The reverse flow technology filter and 150mm ram pipe make use of the physical phenomenon of air tending to move towards surface area's, creating more air flow on the edge rather than in the centre of the inlet. The unique design of the filter cone and the inlet 'tune' the moving air flow to increase its speed and therefore its pressure maximising the laminar air flow into the engine, again resulting
in increased power.

Wildcat 1000i H.O.

Thorney Offroad, a division of Thorney Motorsport are launching the new Arctic Cat racing side by side atv. The Wildcat 1000i H.O. is an awesome, all powerful machine and has it all when it comes to extreme offroading.

In fact, it’s so good that Thorney Offroad are planning to race two of these Wildcat 1000s in competitive side by side racing. Being a race car team Thorney are adept at modifying the Wildcat 1000i H.O. for competition with upgrades to the chassis, cage, suspension, brakes and power train which maximise the already stunning performance.

A website dedicated to the Wildcat 1000i H.O. has been created by 2geedesign for Thorney Offroad and can be found at www.wildcat1000iho.co.uk. Here you will find full details on the Wildcat 1000 to whet your appetite.

At just £13,990 plus VAT why not be the first in the UK to own a Wildcat 1000?
