Another question we are constantly being asked is about remapping and correct set up and why this is better than a hand held unit.

Many people like the convenience of installing a map from a hand held unit (and are often ‘sold’ the same results as bespoke mapping, which invariably is not the case), but without checking it or seeing what it is doing for the car, the results are simply ‘hit and miss’. Put simply unless ecu software is properly checked and optimised to each car, you are unlikely to get the results you are expecting (or have been sold!)

Here’s a graph for an Astra VXR which we were asked to dyno which had a lower front mounted intercooler fitted, a full 70mm Remus Exhaust System and an unchecked map from a hand held unit. The resulting dyno figures show the map gave worse results than the factory software (where we have seen 270bhp on a car with exhaust and intercooler fitted):

Astra VXR Competitor Stage 3 : Before

This set up, correctly mapped should really have been producing at least 285bhp, not 252bhp!!

At the customer’s request, we changed the intercooler for one of our Full Height Front Mounted VXRacing Intercoolers and fitted a full 76mm system. Once properly remapped, datalogged and set up on the rolling road we achieved:

Astra VXR Courtenay Sport Stage 3 : After

And finally here are the before and after graphs, showing the differences. Much more power and torque right across the rev range, which will totally transform the drive of the car:

Astra VXR Stage 3 Comparison

Total Vauxhall March 2012 Issue 133

The latest issue of Total Vauxhall (March 2012 Issue 133) features Wayne Townsend’s 479bhp Courtenay Sport build Astra VXR, covering a total of 8 pages.

The car has been bespoke mapped and set up on the rolling road to the spec of the car and the spec on this car is huge; V Band Cast Manifold, Garrett GT3076, TiAL external wastegate, Low Comp Pistons, Steel Rods, High Flow COurtenay Klasen Inlet Manifold, Thermal Gaskets, Uprated Head Gasket, Courtenay Klasen High Lift Cams, 630cc Injectors, 90mm AFM, 3.5 Bar Map Sensor, Uprated Fuel Pump, External Swirl Pot and Uprated Pump, Uprated Fuel Pressure Regulator, Nitron 2 Way Coilovers with KW V3 Springs, TD Pro Race 1.2 Wheels, VXRacing AP 4 Pot 343mm Brakes, Rear 292mm Brake Upgrade, Quaife LSD, Lightweight Billet Steel Flywheel, Sachs Uprated Cover and Uprated Sprung Paddle Disc, Full 76mm Exhaust SYstem, Courtenay Sport VXRacing Full Height Front Mounted Intercooler, Uprated Courtenay Sport Water Radiator, and it was immaculately turned out by Autobrite Direct, who detailed it to perfection for the photshoot.

On more than one occasion we have extolled the virtues of a good, free flowing 76mm sports exhaust system for Astra VXR to get the best performance results out of remapping correctly.

Well here is another classic example……..

The car in question is an Astra VXR 2.0 Turbo which was fitted with a Stage 1.5 Hybrid K04 turbo (with exhaust wheel cut back), a large full height front mounted intercooler and a ‘one-off’ made to the car exhaust system which in places reduced to 50-57mm.

Once mapped the results were as follows:

Astra VXR Stage 3 : Poor Exhaust System : Before

Results: 278 bhp and 318 lb ft torque.

Upon examining all the evidence from the rolling road and datalogging, we concluded that the exhaust system was the limiting factor. Some might say it was easy for us to blame the exhaust (which we didn’t supply)….. why could it not be the installed software??

Well, we could comfortably rule out software based on the fact that all our maps are optimised on the rolling road and datalogged. so we knew we couldn’t get any more ignition timing into the software or take any more fuel out (without risking safety).

So we had the car back a couple of months later and fitted our full 76mm sports exhaust system, changed nothing else and ran the car back on the same rolling road, resulting in the following:

Astra VXR Stage 3 : 76mm Exhaust System : After

Yes, no word of a lie results of 305bhp and 348 lb ft torque, aided by the Stage 1.5 hybrid turbo, the full 76mm system and the cold February dyno cell temperatures.

Here is the before and after graph. The gains speak for themselves. Lots more power and torque right across the rev range:

Astra VXR Stage 3 - Good Exhaust vs Poor Exhaust : Before and After Results

So if you are trying to decide on which exhaust system to fit to your Astra VXR, we think we’ve just made the decision much easier for you. A good exhaust system may cost a little more, but you will get the benefits from fitting it.

Courtenay Sport would like to wish all our customers, fans and friends a very Merry Christmas and a Happy New Year. Thank you for your continued support during 2011.

We look forward to seeing you in 2012.

The dates for the 2012 Production Touring Car Trophy have been announced as follows:

The Championship returns to Oulton Park to start the year with a hectic one-day meeting at the picturesque Cheshire circuit where two rounds will be run. The second event is at Donington and runs alongside the Britcar Championships before moving on to Brands Hatch on the Indy circuit. The Snetterton event runs alongside CIK British Kart Grand-Prix and at Thruxton there are races scheduled for the British Truck Racing Championship. The season finishes with races at Rockingham and Croft, which always provide exciting racing and it is hoped that the title will go down to the last event as it did last year.

Courtenay Sport Garrett Conversion. The brief was to achieve 420bhp with Garrett GT3071 turbo, tubular manifold, 76mm exhaust, 80mm air flow meter, 630cc injectors and Courtenay Sport Full Height Intercooler. The 80mm Astra VXR is maxxed out at around 420bhp so the achieved figure was the best achievable using the given components.

Vauxhall VX220 Turbo modified by Courtenay Sport to Stage Four – 290 bhp / 335 lb ft torque.

VX220 Turbo

2.0 16v Turbo (Z20LET) VX220 finished in Coral Blue Pearlescent with a blue soft top roof.

This car is a One Owner car from new, registered on 26 September 2003 (53) and has covered just over 25,000 miles, has a full service history and is in all but immaculate showroom condition throughout. You will struggle to find a better example of this car. Standard features include ABS, Driver’s Airbag and Alloy Wheels.

The car also benefits from the addition of Paintshield stone chip protection film which as the pictures show is all but invisible. It has been fitted across the front clam and nose area, edges of the turbo ‘ears’, the door mirrors and the headlights for protection from stone damage, from which these cars can suffer very badly.

The car has been garaged overnight for its entire life when not in use.  It has not spent any time outdoors over the winters, and has spent the last 12 months off road (SORNed) and garaged.

The car has been regularly detailed (washed, clayed, polished) and the paintwork has been regularly waxed, as the pictures show.

This car was specified with the following factory fitted options:
Coral Blue Pearlescent Paint
Blue Hood/Soft Top
Remote Central Locking
Leather Seats, Door Cards and Centre Console
Blaupunkt Los Angeles MP72 Stereo Radio/CD/MP3 Player – Security Coded
Additional Front Tweeter Speakers
Passenger Side Footrest
VX220 Branded Floor Mats
Rear Stowage Net

Additional modifications to the vehicle are as follows:

Courtenay Sport Bespoke ECU Remap to 293 bhp and 335 lb ft torque
Full Stainess Steel Milltek Sports Exhaust System
Pro Alloy Charge Cooler System
Pro Alloy Enlarged Alloy Water Radiator
VXR (Astra Z20LEH) Turbo Charger
Uprated Actuator
Lightweight 5.6kg Billet Steel Flywheel
Fast Road Clutch (drives like OE)
Enlarged Plenum and Enlarged Hose
Enlarged Pro Alloy Intake Pipe
16 Groove Brake Discs All Round
Mintex M1144 Brake Pads All Round
Uprated Polyurethane Engine Mounts Front and Rear
Carbon Fibre Dash Panels and Door Escutcheons
Genuine VXR220 Matt Black Petrol Filler Cap and Surround
Boost Gauge
Colour Coded Rocker Cover
Matt Black (Painted) Windscreen Surround
Matt Black Opel Blitz (removal of the V grille allows more cold air through to the water radiators)
Paintshield Stonechip Protection Film over the front clam, headlight and door mirrors

The cost of getting a standard VX220 Turbo to this specification would be in excess of £8,000

This has to be one of the best examples of a VX220 Turbo around. You will struggle to find a cleaner, better looked after example. The car will have a new 12 Month MOT Test prior to sale.

Both keys and remote key fobs are present, as is the security code card for the car, the book pack with full service history and previous MOT Test certificates and Tax Discs, the stereo front case and the original stereo SD security card. Private Plate is to be transfered at time of sale.

Clear on HPI, No Outstanding Finance.
