So a 7 inch replacement mount can transform your car and optimise performance? Absolutely – that’s exactly why Rear Torque Mounts exist in the Revo range.
Let me explain…
No matter how much power you have if you’re not transferring it to the road then it’s wasted. Fact.
When you start modifying any car you accept that, generally, it all becomes about trade-offs. A larger turbo offers vastly increased power but has more lag. Track-focused pads stop you like nothing else, but squeal like a scalded pig on the road… etc. You get the picture.
More Performance. No Trade-Offs.
But what if there was a performance mod that offered a host of benefits, with virtually no trade-offs at all? Well there is.
When mainstream manufacturers release performance models of their road vehicles business logic dictates that they still make them ideal for ‘the mass customer’. This means the cars are still laced full of parts that are designed to work in favour of comfort at the expense of performance.
A rear torque mount is a prime example of this.
What Does It Do?
Known as a rear torque (or rear engine) mount it’s situated underneath the car and connects the engine to the subframe to brace the engine in place.
Made from Billet 6061. A simple 10 minute fit. Packed with benefits.
The stock one is typically a lump of metal with very forgiving rubber bushing. And here lies the first key problem. The soft bushes are designed to optimise comfort by absorbing the maximum amount of vibration and movement when the engine is running. Great if you prefer comfort over performance.
Lost In Translation
The trade-off means that when you accelerate the engine twists and the bushes absorb the twist and vibration. This ‘twisting’ means that the maximum amount of power is not being applied to the road, it’s being lost in the movement.
Wheel Hop
Consequently, under hard acceleration this leads to wheel hop – so rather than your tyres putting the rubber into the road and optimising acceleration the wheels literally hop off the ground.
You’ll feel this in the car by a rather off-putting juddering sensation. Nasty. I’m sure you’ve experienced it for yourself at some point in your motoring career.
Simple Solution
The solution is to fit an uprated rear torque mount, which has stiffer bushes and is purpose-designed to prevent wheel hop meaning you put the power into the tarmac rather than wasting it ‘mid air’.
See. ‘Free’ power.
Added Perks
There are also a number of other benefits – you will also notice an improvement in gear shifts. There’s a feeling of increased preciseness too, due to the reduced movement.
Sounds Good! But What Are The Trade Offs?
Well, there aren’t any, really! To understand this better we need to talk about NVH. A term you may (or may not) have heard of. But it’s key here.
NVH – Yep, Let’s Get Technical
Noise, vibration, and harshness (NVH) is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks.
This is applicable to engine mounts because, broadly speaking, aftermarket engine mounts result in increased cabin vibration and noise, most noticeably at low revs or when the air con is on.
However, due to the specially selected Dual Durometer material used for OUR bushes, there’s virtually no increase in vibration under typical driving conditions.
OEM Comfort. Race Car Performance.
Having driven our Fiesta Mk8 ST with both the OEM and uprated mounts, you’d be hard-pushed to notice much difference. Even with the air con on and sat in traffic (the most extreme case), you might only just about notice the car has an aftermarket replacement! Impressive.
If you really went all scientific and specifically looked for an increase in NVH you might find it, but it’s minimal and certainly a tiny price to pay for the improvements elsewhere.
Custom Wave Shape Bushes
But the type of material used isn’t the only reason there’s a negligible shift in NVH. The ‘wave shape’ of the outer profile of the larger bushes for the Mk8 Fiesta ST has been designed in a way that the contact point of the bushing is reduced by over 50%, while still maintaining full rigidity of the mount.
By doing this the NVH that is transferred through the body to the chassis is reduced but still retains all the performance.
There are a total of 4 bushes in the kit for the Fiesta ST Mk8 – the two smaller ones are also made from a custom Dual Durometer material to ensure all of the same benefits.
Precision Fitment Billet
Come on, I mean who doesn’t love billet stuff? Made from aircraft-grade 6061 T6 aluminium the main housing of the Fiesta mount is a direct replacement for the OE unit.
CAD designed for precise fitment the machined housing is a single piece of billet material giving you a solid base for the uprated bushings to sit in. Finished with an engraved Revo logo.
Machined Pins
Specially designed machined pins were created for the mount to locate the bolts through the bushings without damaging them.
We opted to make the larger bush pin out of a single billet piece as it removes the opportunity for failure and gives a stronger more direct fit. The smaller pin is made from stainless steel further increasing the life of the product.
If you want better performance, and I assume you do if you’re reading this, then start small and build your car up.
Whether your car is straight off the production line (or has been treated to numerous upgrades already) an engine mount is one of those no-brainers that goes somewhere near the top of the list.
Maximise the car’s torque output. With virtually no trade-offs. Pretty much FREE power.
It’s a very simple upgrade that can be fitted on your drive at home with minimal tools, or in 15 minutes on a workshop ramp.
If you’re not in the uprated rear-torque mount club just yet take a look – it’s one of the least expensive, performance-enhancing bolt-ons you can do.
