Mini Cooper S 15% Pulley Upgrade

Hey everyone, its been a while since another episode! In this episode, join me while I install a 15% reduction pulley! I also install a colder set of spark plugs and a new belt while doing the upgrade. Interestingly or frustratingly it didn't all go to plan, but that makes it all the more interesting!
For reference, I'm working on a Mini Cooper S R53 2004, and parts used:
Cravenspeed 15% Pulley
Gates belt
NGK Iridium Spark Plugs
I hope you enjoy it! I'll be bringing more content too over the coming weeks. Stay safe everyone!

The cars body is so clean, so lucky to live in a warm climate where there is no salt. I also enjoyed the property and the quietness!

[@ozmini6968]

Thanks for your comment, yeah I’m lucky I got a clean car. Not leaving in a salt environment really helps under the car and rust. Cars in Australian weather are pretty good in that regard. I’m really surprised when I see cars in UK where there’s high salt. Yep again lucky to live in a bush block!

[@johnhibbs6508]

I just bought a R53. My first project car. I plan to install a 15% too. Your channel is perfect for me.

[@brianroyle2533]

Spark plug socket drill a hole through the socket tap it and put a grub screw with a allen head

[@zokusharuuku1091]

When your spark plug socket comes off you just have to put the extension back in and try pulling up at and angle wiggling it.

Love the animals in the background please post a video of them just subscribed !!!!

[@Niki_R188]

You could put the new plugs with the existing spark lead just to get them to catch half a thread and then take the bloody rubber out of your tool to make your life easier..been there done that..

[@ozmini6968]

Ahh, didn’t think of that! Good idea! 😁

[@jaysemartinez2943]

UNO you could have just taken the rubber out of your socket and just tightened the plugs same way 😂

[@johnhibbs6508]

My R53 has 100k miles so I plan to clean the intake valves. Using chemicals instead a walnut blasting . Going to take off the intake manifold. Maybe I should start my own channel. Is it hard?

[@brianrabbit7159]

I did 19% it was amazing

[@JexL92]

great video, makes me want to install one also

[@ozmini6968]

Thanks, it’s a great upgrade, makes a noticeable difference for sure

[@davebalaam]

Cracking video. Definitely something I'm looking to tackle in the future. Quick question regarding using the puller: would applying some heat to the pulley before fitting and using the puller help with the removal of the pulley, or is it difficult to do that without setting fire to something nearby?

[@ozmini6968]

Thanks I’m glad you liked the video. Hear may help the pulley but not the puller. Honestly not sure. For me the chain vice grips was the key, clamped down as hard as I could. Alta sell a different style puller that could offer a better clamping force but didn’t try that.

[@johnhibbs6508]

Are there any ECU changes? Are you going to change out the camshaft?

[@hasaelmonty7531]

Pretty nice video very informative

[@ozmini6968]

Glad you liked it

[@emersenandreasen8457]

Hey oz mini you still got ur mini cooper s ?

[@nicolaisadowski8787]

hey, where did you get the rev counter for the middle? or did you build it by yourself? 🤙🏽 great vid!

[@ozmini6968]

Hi, no not aftermarket. In Australia the middle rev counter is standard for this model. There is another version that has what's called a Chrono Pack and that has three gauges in the middle instead

[@MrSamourai77]

Hi! Good job👍 did you made a remap after pulley upgrade? Thanks

[@ozmini6968]

No, no need for a remap. I do have a Cam to go in and that will require one though

[@stevene5194]

This design is NOT what you want unless you drive like a old lady, Over time even with thread locker that bolts work their way loose and causes the collar to widen , wobble, and will not tighten up again. Look for the type that has 2 bolts that hold the collar tight on the shaft, and 3 bolts to hold on the pulley.

[@johnhibbs6508]

How do you film from your head?

[@PekanOsijek]

Now after a time do you would say the 17 would be better? Or what would you prefer? Whats the big different between 15 and 17 ? I thinking of make the same move an dont know if 15 or 17...? What would you say...thank you great video

[@ozmini6968]

Hi Pekan, I’m really happy with the change the 15 made, it’s a must upgrade. I can guess the 17 would give a little more midrange pull, it’s roughly 2 psi difference so I should notice it if I did it. If taking on a track is your aim I’d say stick with 15, because a 17 will generate more heat. If it’s a road only car maybe go 17. I think at some stage much later I might try a 17 just to see first hand if with an upgraded inter cooler I could get get the most out if a 17

[@PekanOsijek]

@@ozmini6968 thank for the answer. It should be only a fun 2nd daily. Heat should not be the problem for maybe 4 pulls in raw. And little bit fun on curvy roads. Upgrade cooler maybe go in one when i am at the mechanics. Thnaks for the infos

[@K03sport]

You can also do a +2% crank pulley. Turns the 15 into a 17 and the 17 into a 19. But as said, more sc spinning generates more heat and wears on the sc gearbox more

[@GloriosoMD]

Just be aware that if the SC has a lot of milage on it, it can shorten its life. I did mine and 3 months later have to change the SC 😔

[@ozmini6968]

Thanks for the feedback, hopefully mine should last a while as the car has a little over 110k. Although I am thinking of doing a service on it

[@JexL92]

How many miles was on your Sc?

[@GloriosoMD]

@@JexL92 185k km.

[@alexalpizar4096]

hi my name is Alex I have one Mini Cooper 2002 ,wher you bye this pulley?

[@ozmini6968]

Hi Alex, I actually bought this pulley off Amazon direct from the US. You can get similar quality pulley's off eBay as well, even suppliers in Australia (but they were a quite a bit more expensive for me believe it or not.

[@hasaelmonty7531]

Would like to know where did u get the red trim of the bottom grill please reply

[@ozmini6968]

Hi, the red trim was on the car when I bought it, I think it was aftermarket. It looks like it was just a think plastic strip stuck on. I've actually replaced the front bar completely with a new one (someone backed into me) so its now gone

[@hasaelmonty7531]

@@ozmini6968 thank you so much replying back

[@waterlover]

Do you have a link to your intercooler? Wanted to know where you got it

[@ozmini6968]

I don’t have a link anymore but it’s just an eBay intercooler, which made an immediate improvement. I’ve now installed a “not so hobo” diverted which has made it even more effective which I’ll show in another video coming

[@waterlover]

@@ozmini6968 diverter? Really have to see a link to that video want to get one too.
