  1. Sound difference: Non-res vs. resonated decat

    Engine & Drivetrain
    Greetings, I've got a Milltek non-res cat-back. It's definitely an upgrade from stock, but I'm not really satisfied. It's loud externally, but quiet inside the cabin. Also quite high pitched. I'm not fussed about the external sound and I'm not fussed about pops. My priorities are: 1) Low...

  3. Exhaust Sound

    Engine & Drivetrain
    Hi Guys, I have a JCW R53, it has a 4-1 Janspeed Manifold and Decat on the JCW exhaust with the silencer removed, after having it all on for maybe 3-4 week its quietened down a lot, was just wondering if anyone has any ideas as to why? Thanks

    R56 General
    Just brought a Janspeed manifold off of here.....just wondering if it is actually worth heat wraping it before i put it on? Cheers
  5. Project Mini:RMR - Rotrex Mini (goal of 500+ bhp again)

    The Projects
    Well I think I'm at a point now where I can just about justify a project thread. I never ever anticipated to get into what I have, but hey ho :) I bought my JCW R53 not long ago (having had a MCS before) as a promotional car for my photography business. However, it became quickly apparent that...
  6. mcs' project

    The Projects
    Well, after some thinking and a few mods I've started modifying my '06 JCW R53. Big mods started some weeks ago when I ordered the 4-2-1 with 100 cells cat to Mini Motorsport UK. I also got the 225hp remap soon to fit a camshaft. Hope to get after that around 235-240hp. Dry battery's been...
  7. Fitting a new bypass valve

    Engine & Drivetrain
    Got a new BPV which i'm looking to fit at the weekend. Looks fairly simple in principle but maybe a bit of a ball ache to get to? Anyone got any advice when fitting it? Or has anyone made a guide? :thumbup:
  8. Would this fit a MINI GP?

    R53 General
    Sorry for probably a stupid question, but as I am new to this, thought I would ask! Janspeed Mani & Decat - BMW MINI MANIFOLD & DE CAT MINI COOPER S JANSPEED SM901 on eBay (end time 30-Jan-11 08:07:20 GMT) USED IN CONJUNCTION WITH -...

    Photos to come soon! The project is a suprise, as i haven't seen anything similar on a R50 or R53 :)
  10. Janspeed 4 Branch Manifold Fitment to R53 Cooper S

    How To Guides
    Right then, thought i would give people an idea on how to fit one of these after our efforts today. Only need basic tools and some elbow grease so can be done easily enough by some one handy with the tools :thumbup: Ok then, here's what we did: 1. First things first, make sure you have all the...
  11. Operation: Vacuum Gain System (VGS) - Thoughts?

    Engine & Drivetrain
    This mod was developed by Andy from Ross-Tech.com... Details to follow: The brass vacuum nipple on the downstream side of the BPV is definitely the hardest part to get to. For easiest VGS installation, I'd recommend the following procedure: ALPHA METHOD 1) Disconnect the short rubber...
  12. What mods have you done this week?

    MINI Chat
    So what mods have you done in the last week? Thought it time someone started one of these, so tell everyone what you have been doing to your MINI this week. Anything counts, little or large. Myself, I just finished fitting an auto-dimming mirror to my 03 MCS. It originally came from a cab, so...
