    Not looking forward to the running in either 😕 I only do about 3k a year so it’s going to be some evening driving I think after work to get it done

    Power wise looking at 500 plus

    Either Sabre  devil development , or the Mountune 520 (but different mapping )

    How many miles you done now Matt??  Once the rings have bedded in ( after about half an hour) thats it, nothing else is going to bed in or run in, the crank and bearings will look the same now as they will in 20000 miles if built properly and proper oil etc.  A few half throttle runs through the gears to 4500, then a few 3/4 throttle blasts to 5000 and then youre good to go !  Soft initial running in is NO good at all, you need to force the rings into the bores to get them bedded, and thats only achieved by plenty of combustion pressure. Run it no boost and gentle, lots of rings and bores get glazed and never seal fully/get smoky especially with todays oils that DONT allow metal to metal contact. Thats why we run engines in on crap cheap oil for 50 miles then refill with the good stuff, then FLAT OUT !!



    No nothing.

    No Mods. No rockers. Just a chunky knob, thats now been replaced by an RS knob innit.

    No tackiness.

    Std as Ford intended, but with a space saver wheel and jack and nuts and wheel brace. oh.. and flaps, a man has got to have flaps.

    Innit?

    Stage 2 Piper cams are they the BP270 profile with a 7000rpm limit. Not used these in the Mk3 but did in an XR2 seemed fine and could feel the difference instantly. Tickover slightly higher but in comparison to the Stg3 very very similar.
    A nice drivable cam profile



    RS Edition.

    The rest of the “M” maps suck

    @white-rs2

    yes I think they are the 270 profile

    I was told they drive nicely without too much mapping, where would the extra power come higher up the range I am guessing ?

    Ive got 270’s and all good… nice change in the sound to the car, full rally car mode at the moment tho with so many changes and no tune 😅… really cant wait for the 27th Next month


    @71-bda
    states i don’t know why mental long run in periods are being done? 75-100 mile with correct procedure done…

    Also don’t understand how an engine builder would build new / forge, then let the customer with no or very little experience run in the engine. Or is it a kind of disclaimer, if anything is wrong…. “must of been run in wrong” 🤷🏻‍♂️

    @Matt. B

    Who built your engine wasn’t it at Mountune with their ex mechanics ,I think I spoke to you briefly at Ford Fair

    I am also concerned about the running in because I have had blowby on a engine before but at the end of the day I think we have to listen to the engine builders as they are providing the guarantee , what were you specific instructions ?

    Yes mate FJRS formally mountune built it. Instructions were first 500 miles no more than 4k revs and heavy load then oil change and able to use all the revs but dont go mad for another 500.
