EBC GD Sport Discs

Over the next few months EBC GD Sport Discs will change from gold to black. The current gold coating is being phased out and will be replaced by a Black GEOMET coating, which is a new long lasting corrosion resistant finish.

This means that over the next few months the traditional gold finished EBC discs will be replaced with black coated discs. They will still be manufactured to the same high standards.

Astra G – LSD and Uprated Clutch and Flywheel

We recently had this Astra G GSi Turbo in with us to have a Quaife Limited Slip Differential fitted into the F23 gearbox and whilst the gearbox was off the car we had the opportunity to fit a lightweight billet steel flywheel and uprated clutch cover and 6 paddle disc, in preparation for some big horsepower upgrades.

Work In Progress:

Engine Bed/Subframe Bushes – Astra G/H and Zafira A/B

Front End Improvement for Astra G/H and Zafira A/B.

Poweflex have engineered a solution to replace the factory engine bed/subframe bushes in Astra G/H and Zafria A/B which can be prone to failure and contribute to vague handling. These stiffer engine bed bushes help improve the front end feel of the car especially during turn-in and cornering. By removing the flex in the subframe bushes the handling is improved giving a more positive feel to the front end.

These Front Subframe Bushes feature two polyurethane top-hat style bushes that makes for simple installation and durability. The bushes house a stainless steel sleeve and are supported by zinc coated steel washers at each end for increased support under load.

Poly bushes will be resistant to corrosion and the addition of a stainless steel sleeve should help prevent the bed bolts from seizing into the bushes, which can happen with the factory bushes.

Suitable for Astra G, Astra H, Zafira A and Zafira B All Models.

These new bushes replace OE part numbers 90498689, 9223022, 9223023 and 13107328 used across the model ranges.

The application of corrosion resistant materials, robust design and the Powerflex Lifetime Warranty ensures the subframe need not be removed again once fitted, unless removal is required for other service work to be carried out.

These bushes are available in Purple Series 80 Shore Road Spec material for vehicles that are mainly used on the road and also Black Series 95 Shore Track Spec material that suits vehicles being used in Motorsport or predominantly on the track.

Purple Spec: £22 each Black Spec: £24 each

6 bushes required per subframe.

Professional installation is recommended. The ideal time is when the subframe is removed to allow access to the gearbox or clutch.

Focus ST Remap

Just for a change we recently had a Focus ST here for remapping and rolling road set up. Already fitted with a cat back exhaust system (the standard downpipe and cat had not been changed) and an intercooler, we remapped the ecu and carried out a rolling road set up achieving 261bhp and 311 lb ft torque.

Astra H VXR K06 Conversion

One of our recent jobs was this Astra H VXR, brought in to have a K06 turbocharger fitted (complete with an uprated recirculation valve), along with our CSRacing Full Height Front Mounted Intercooler. Whilst in our workshop it was also converted to Evans Power Cool 180 Waterless Coolant.

Already fitted with a 70mm exhaust system it was onto the rolling road for mapping and full set up. During mapping the mid range and top end boost was reduced slightly due to the 70mm exhaust system giving more back pressure than a 76mm system and also because the engine did not have steel rods or uprated valve springs. Once the ignition timing and fuel were optimised we saw results of 304 point something bhp (so nearly 305bhp!) and 341 lb ft torque. With a 76mm system estimated gains are 305-310bhp so this particular car is making good power on a 70mm system.

There is still some in reserve to come for this car once it has a 76mm exhaust system to help with back pressure reduction as 310bhp+ is more than possible, with potentially even more should an inlet manifold, steel rods and uprated valve springs/shims be fitted.
