| Lovin' every MINI of it! | Scotty is right. I don't think that your TLC will be affected but if you have issues with the engine and they see the pulley they may (very possibly) void your warranty. It is a risk you take with modding. Also, you need to inform your insurance company as they may not cover you if you are in an accident. Global Moderator ![]() |

| i love that noise | the whole idea it to keep the car as stock as possible while just giving it that little edge so was thinking jcw airbox and a 17% pulley from alta as its the most stock looking one was just concerened with the whole idea of turing up at the dealer and them going to change the belt and finding it doesnt fit so i take then that the belt isnt changed as part of any service??? |

| Lovin' every MINI of it! | You could take your own belt for them to put on. They will know that you have a different pulley the minuet that they see it. Any reason that you are going 17%? I know that you can get more juice out of it, but you may also give yourself some minor problems without a proper tune. Global Moderator ![]() |

Offline | Guys, Your are wrong on TLC..... here is the copy of the TLC contract..... SEE POINT 5 TLC is invalid with a smaller pulley...... however many dealers chose to turn a blind eye.... 1 MINI tlc must be bought and paid for within 30 days of taking delivery of a new MINI from any MINI dealer in the UK. 2 MINI tlc covers the cost of the parts, lubricants and labour involved in all MINI servicing for 5 years / 50,000 miles, whichever milestone is reached first. It does not cover repair and maintenance items, such as tyres, brake pads etc. If in doubt, ask your MINI dealer for clarification. 3 Servicing must be carried out at a MINI approved dealership by MINI technicians as specified in the Owners Manual. 4 Servicing conducted under MINI tlc must be carried out in line with the Manufacturer's time and mileage recommendations. 5 Any form of tuning or performance enhancement that is not MINI approved invalidates the MINI tlc agreement. 6 MINI tlc can be made available for non-UK sourced cars, but not at the special £150 inclusive of VAT offer price. Ask your MINI dealer for a quotation. MINI tlc is only available on standard UK specification MINIs. 7 Additional services not covered by the vouchers in a MINI tlc book are not included in the MINI tlc package. Manufacturer guidelines are subject to change. 8 MINI tlc is transferable to subsequent owners of the car but not transferable to another car. Manufacturer's servicing guidelines are subject to change. 9 MINI UK reserve the right to amend or withdraw this offer at any time. Cheers Perm ![]() |

| i love that noise | DaFlake there is no real reason i am going for the 17% one just thought 15% is a bit much and 19% a bit wee this is the first car that ive owned / tuned with a supercharger previous car history bmw e46 330ci m sport - alfa romeo 145 2.0t cloverleaf - volvo s60 2.0t etc etc so im new to the supercharger game........ my plans are reduced pulley jcw airbox with upgraded filter and electric flap removed gtt reroute pipe for exhaust all 3 gtt front strut braces etc etc any advice you can offer would be gratefully welcomed |

| Lovin' every MINI of it! | My only concern with a 17% is that it seems to border on what is needed to smooth it out from engine to engine. I have seen some guys that can run it with no problems and I have seen others that need the remap to get rid of faults. Some tuners will argue with this, but I think that a 17% pushes the stock ECU a bit to much. Global Moderator ![]() |

| Lovin' every MINI of it! | Nope, it is actually in my sig. I have a 15% MINI-Madness pulley with CAI and an MTH remap.I have installed 17% pulleys and the guys that have them love them. Only one has complained about the engine light coming on and a remap cured it. Global Moderator ![]() |

| i love that noise | ok call me stupid if you want but i just want to clarify that the 15 % pulley produces the smallest power improvement and the 19% produces the largest i.e 15% runs fine 17% runs ok but may require remap 19% needs remap ??????????????? p.s thank you very much for the help |

| Lovin' every MINI of it! | Depends on who you talk too. Once you go past 15% you have to start worrying about heat management. This can actually cause a loss of performance rather than an increase. 17% is still fairly safe but most people have found that 19% is pointless. This is why 15 and 17 are the most common. 15% is a safe bet as it is the closest to the JCW (14.5 approx). 17% is a good bump but you may need some additional tweaking. 19% you will need to really tweak to get the performance where it should be.

| MINI2 Senior | I have the GTT220+ kit (17% pulley). I have no problems without a remap and my dealer still honors the TLC service plan; I did check beforehand though :-) GTT, GRS, Janspeed, JCW, OMP + various other bits - 232.6bhp, 191.2lbft on 1320's rolling road |

| Lovin' every MINI of it! | I just want to make sure that you and everyone understand what I am saying. The 15% pulley is the least problematic as the 17% can introduce other needs. This does not mean that the 17% is bad.... It just means that there are other things that you might need to do to get it running perfect. ![]() Global Moderator ![]() |

Offline | You can always go to a increased crank pulley to get a bit more juice if you want to boost up your 15% pulley anyhow. See how the car goes with the works motorsport airbox (this is the stripped out version of the JCW) and the 15% pulley....if its all good then start some other power mods and maybe a crank pulley is a possible choice...this could give you a similar effect from a 15+crank to a 17% anyhow. |
