Background to POWERFLEX

EPTG Ltd (European Polyurethane Technologies Group) was formed in the UK in 1996 to take advantage of the significant advances made in the development of polyurethane in recent years.

The company has wide experience in automotive suspension and chassis systems and combining these design skills with advanced polyurethane manufacturing techniques led to the development of a wide range of high performance automotive polyurethane components now known the world over by the product name POWERFLEX.

The stainless steel components are machined on the latest computer-controlled equipment to ensure perfect repeatability and quality.

The moulding and tooling, design and manufacturing are carried out within the factory ensuring very rapid response time to special projects and complete communication between development, prototyping, testing and manufacturing departments. Component manufacturing is carried out with the latest automatic processing equipment ensuring 100% right-first-time quality. Testing of new components is carried out both on the vehicle and on test rigs.

All of these factors combine to make Powerflex the number one performance bushing.

BM Performance Centre stocks and sells both Road Series and Black Series bushes (for track and motorsport use) and suspension components.

Road Series – for Road and fast Road use.

POWERFLEX Road Series bushes improve your cars’ road holding and chassis performance by controlling the amount of unwanted flex in the suspension. This means the suspension is doing what it is supposed to. It means your tyres have greater contact with the road at all times, therefore, improving safety and performance. Correctly formulated polyurethane is as good if not better at noise, vibration and harshness suppression when compared to worn rubber. Our Road bushes offer Prolonged tyre life, Improved performance, Increase safety, and Greater cost-effectiveness.

Black Series – for Track and Motorsport use.

POWERFLEX Black Series bushes are manufactured using our Black 95 Shore A compound to provide maximum control of chassis geometry. They are designed for the Track, ready to Race and are engineered to be the best. This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material. If your requirements are purely for the ultimate in handling and chassis performance then Powerflex Black Series are unique, offering the most precise and accurate alignment for your chassis.

OUR MATERIALS

Our materials are colour coded to make them easily identifiable. Below explains the shore rating and their common uses.

Red 65A – Used for our Universal exhaust mounts and diesel engine mounts.

Yellow 70A – Mainly used for engine mounts, diff mounts and subframe mounts or areas where the bush needs a lot of movement and absorption.

Purple 80A – Our most common material. This is used in most areas of the suspension and provides the right mix between performance and compliance.

Black 95A – Our hardest material. This is used mostly for our Black Series range or in our Road Series where the vehicle’s standard suspension demands require us to use this hardness of material i.e. in areas of high load.

This is a replacement part that uses our Black Series material to boost stiffness over the original part by 18% to withstand increased loading seen by this position on the car. 

PFR5-4026 is a replacement bush that features a built-in support washer, providing further stability of the diff under acceleration. PFR5-4026 can also be used in conjunction with our PFR5-4030 dual-mount rear differential bracket to mount two bushes into the factory positions. Made using our signature Black 95A durometer polyurethane and Black anodised 2011-T6 aluminium, to reduce drivetrain deflection and the potential for wheel-hop during hard launches. PFR5-4026 bushes can be fitted with our PFR5-4030 dual-mount rear differential.

Flimsy Nozzle
Size: 2 fl oz
The nozzle is so flimsy at the moment I pressed on it it popped off the can into the gas tank. I didn’t press it softly but I also didn’t press it very hard either, getting it out was a huge pain in the butt.

Helped to improve combustion in 12 year old Mercruiser 3.0L engine
Color: Blue, Number of Items: 1
I used the whole bottle in 1/2 tank of questionable gasoline from used boat from dealership, with no idea what mixture of gas water and particulates was in the gas tank in this 12 year old boat. The dealer started up the boat, and it was taking a minute to get the idle going. He mentioned that the gas was a few months old, but I am guessing that is was more like 6 months old. This is the TKS engine, self priming. I think some water / condensate was in the tank. Before taking out to first trip, I added bottle and 5 gallons fresh gas. That trip to the lake, I still has some issues getting it to start easily. Ran OK, not great that day, went home, changed cap and rotor and wires. Next trip, 1 week later, the 3.0L started great, ran great, I am not sure if it took some hours to fully mix and interact with the old gas, neutralize the water, and perform it's reactions, before it made existing gas more combustible, but that is what it seemed like to me. ***UPDATE**** - I had strange fuel issues the next season after using this product. I had to replace the fuel pump and many other fuel delivery components including the carburetor. Not sure if this contributed to the fuel system failing, the long term effects outweigh the short term gains.
