100% of the power your Honda Civic’s engine creates must be applied to the axles/wheels/tires to get them rolling and your Civic moving; but what holds the engine in place? The rear engine mount (along with the other two mounts) have the demanding job of keeping the engine in your Civic SI in-place. Unfortunately, the OE engine mount quickly loses effectiveness as the engine power output increases.
If you find yourself fighting for traction and would like to improve throttle response then look no further, the 27WON Performance Rear Engine Mount is the performance upgrade just for you.
Compared to OE and other options on the market you may notice something missing…or is it? With our design less is more; which is why our mount utilizes only one polyurethane isolated mounting point.
The mounting point between engine and RMM has a primary motion and secondary motion.
The polyurethane mounting point on the engine reduces the primary rotational movement of the engine due to the fact that the polyurethane compresses less than the OE rubber.
The rigid mounting point connected to the chassis sub-frame eliminates the up/down motion that the engine follows while the engine rotates. This eliminates associated secondary vibration and thus reduces NVH. More on this in the coming design blogs.
In an effort to reduce weight and maintain strength, the 27WON Performance RMM utilizes an “I-Beam” style design (very similar to high performance connecting rods) to connect the two mounting points. This design provides a reduction in weight without a significant sacrifice in tensile and compressive strength. The weight savings add up to ~1/2 lb vs OE.
The body of the 27WON RMM is manufactured from 6061-T6 billet aluminum for superior strength and weight. The vibration isolation pucks are made from polyurethane chosen for its durability and ability to withstand high forces and heat. The steel sleeve within the polyurethane pucks is manufactured from 303 stainless steel for strength and corrosion resistance.
Noise, Vibration, & Harshness is an evaluation of the various irritants that can be transmitted through the vehicle into the cabin and directly to the driver and passengers. OE engineers and designers spend countless hours reducing/eliminating NVH from vehicles, however, this sometimes comes with a compromise in performance and vehicle feedback. Not all NVH is created equal, an OE designer may consider turbo noise to be unwanted NVH, whereas a performance enthusiast may consider it a desired sound.
At 27WON when designing performance parts that may affect the vehicles NVH we strive to find the right balance of performance improvement and NVH increase. Ideally, we are able to create a performance part that does not affect NVH, but that is not always the case. Examples are exhaust systems, intake system, engine mounts, suspension components…etc.
