Hi all,
Just letting you's know i have purchased a set of Mad Polly Evo 3 slotted engine mounts due to desperation of me replacing the lower rear one every 10,000 or so ks (GETS EXPENSIVE) I have upgraded the turbo, yet to be dyno'd but Torque Pro and Dash Command both say im producing on average around 237hp and 475nm (torque does seem excessive) but its pretty consistent. this is with all details on weight, tire size, gear ratios, drag etc etc etc. Acceleration hits 100 in 4.6 seconds. I have actually snapped 3 bolts on the left hand engine mount when the rear lower mount tore only about 2 months after it was installed!
I have fitted them and they are a perfect fit so had a conversation with the friendly and very helpful guy behind Mad Poly and hes now listed front and rear kit for the Volvo S40/V40 on ebay.
Just a note:
I would only purchase poly engine mounts if have upgraded your engine eg exhaust, ecu tune, actuator adjustment for extra boost etc, or taking the car to the track etc,, and make sure your engine is idling smoothly, eg no vacuum leaks, good spark plugs etc.
These do transfer a bit more vibrations through to the chassis, but if the engine is idling smoothly you wouldn't even notice the difference apart from when the aircon is turned on. Its something i defiantly can live with. After 4 days i barely notice the vibrations.
I am also going to measure up the left and right one, they appear to be evo 4 but have to confirm, and will be in discussions again once i confirm fitment, i am thinking it will go either way eg to hard on the chassis but at the same time may smooth the engine vibration out as the rubber ones allow too much movement (just keep in mind these are slotted not solid as others may have used in passed.)
They are super easy to fit, i did the two lower mounts in around 1 hour and he also has a youtube video on how to do it.
