Revo MQB Chassis | Engine Mounts

Description

Revo Engine Mounts

More power results in more movement during aggressive acceleration. The stock engine mounts, designed to favour comfort over performance, fail to manage axle hop and torque effectively requiring you to ease off in order to gain traction. Designed to significantly reduce this engine movement, Revo engine mounts use Powerflex bushings to minimise noise, vibration and harshness levels (NVH) while drastically improving traction and acceleration. The engine, transmission and torque mounts have been CAD designed to offer OE quality fitment with the performance benefits and quality of a Revo product.

Key Features

• Dramatically reduce engine movement
• Improved acceleration and torque
• Powerflex polyurethane bushings
• Comes with removal tool for torque mount

Engine & Transmission Mount

The primary design goal of the engine and transmission mounts was to provide a management system for engine movement during vehicle operation with increased power/torque, in order to retain vehicle acceleration and tyre contact during aggressive driving. The aforementioned solution must also continue to dissipate the NVH naturally created by the drivetrain. To accomplish this, the bushing design of past Revo engine mounts was retained in the MQB engine and transmission mounts, allowing Revo engineers to focus their efforts on bushing stiffness/type to accomplish the task.

Torque Mount

Arguably the most vital engine mount upgrade to consider, testing highlighted that the engines stock lower torque mount allowed a substantial amount of engine movement to occur. Although some improvements were noted during testing of an insert style upgrade designed to stiffen the standard mount, there was a significant increase in NVH felt in the cabin. This was dramatically reduced when completely replaced with the Revo polyurethane torque mount and also improved acceleration. Fitting the mount does not require the sub-frame to be removed, reducing installation time and the need for axle re-alignment. A Revo installation tool is included to make removal of the OEM mount and                                                                                                                                installation of the replacement as quick and easy as possible.

Materials, Manufacturing & Fitment

Effective design and fitment plays a principal role in managing engine movement to ensure optimal acceleration and tyre contact with the road while dissipating NVH experienced from the drivetrain. Each component has been designed using CAD technology to ensure precision fitment and is supplied with class 12.9 hardware to replace the standard fixings. To ensure optimum strength and durability, brackets and housings are CNC machined from 6061-billet aluminium and finished with an anodised coating to protect from heat and corrosion.

Powerflex Bushings

Powerflex utilises a unique formula of polyurethane, custom designed to ensure optimum fitment in the machined housings. After testing of various amounts of compliance, our engineers were able to fine-tune the final bush to achieve a balance between performance and comfort. Polyurethane is also resistant to oil, fuel unlike the rubber used in the OEM mount which can lead to perishing and failure. Our specified durometers provide a stiffer mount to limit the engine movement without compromising on NVH (Noise Vibration Harshness) levels in the process.

OEM Comfort, Aftermarket Performance

To achieve the optimal balance between performance and comfort, several different durometer bushings were tested on a Volkswagen Golf Mk7 GTI. Bushings were systematically tested at precise increments at each mount location. A 3-axis accelerometer was used to quantify the NVH levels being transmitted into the cabin, as well as the acceleration of the drivetrain during loading.

Accelerometer data gave us a way to compare mount combinations against each other with a low data error percentage and to quantify driver comfort as well as engine movement. Supplemental data was taken from VCDS to ensure each individual test was standardised over a given throttle, RPM and speed range. The graph shows the amount of vibration measured whilst driving through the gears.

Fitment Notes

• Lower torque mount kit includes torque mount and Installation Tool
• Full kit includes engine mount, transmission mount, torque mount and torque mount installation tool
• Performance Engines mounts will produce more vibrations at low RPM then softer OEM Mounts.
