Poly Engine Mount Additions – Astra H VXR and 1.9 CDTi

At our request, Powerflex have added a couple of new polyurethane engine mount inserts to their Astra H range.

Courtenay Sport supplied the relevant OE engine mounts and asked if a lower front engine mount insert for Astra H 1.9 CDTi models and an insert for the Right Hand Side Mount for Astra H VXR and 1.9 CDTi could be produced.

These engine mount inserts fit into and fill the voids in the original bushes and are recommended as a labour saving method of limiting engine movement to improve vehicle performance and reduce the likelihood of engine mount and downpipe failure caused by excessive movement. Some additional NVH may be experienced.

These mounts are now available in both road spec material to reduce engine movement but limit increased Noise, Vibrationand Harshness (NVH) and Black 95 Shore Track spec material, which due to its nature is much stiffer and will lead to significantly more NVH being transmitted.

Side Gearbox/Engine Mount Fitting – Astra G/H and Zafira A/B

Astra G/H 2.0 Petrol Turbo, Astra H 1.9 CDTi, Zafira A/B 2.0 Petrol Turbo and Zafira B 1.9 CDTi have a gearbox side mount that is rubber and prone to failure.

Courtenay Sport approached Powerflex to devise a solution to not only improve the original factory mount, but also give it some additional support and to help reinforce it. In some cases where the original factory mount is not too badly damaged or split, the polyurethane insert can be used to ‘save’ the failing factory mount and prevent further deterioration.

Two specifications of material are available for this mount: Yellow for road use (Shore Hardness 70) and Black (Shore Hardness 95) more aimed at trackday/competition use as it is much stiffer.

We recently fitted a yellow mount insert to an Astra H VXR which had covered just over 46,000 miles and the factory mount was already showing signs of weakening due to splitting which if left would ultimately deteriorate fully and  fail completely.

Once fitted there was no noticeable increase in NVH (Noise, Vibration, Harshness) into the vehicle. The vehicle used also had an uprated front engine mount insert fitted. Additionally it was noted that the gearchange had improved and became smoother due to the reduction in gearbox movement at gearchange, due to the uprated gearbox mount insert.

On vehicles with a full set of uprated engine mounts, some minor change in NVH may be experienced by fitting this additional mount.
