Hi i have a 2005 mcsc, at the moment I have a miltek cat-back system fitted and bmc ram induction kit.

Got three hours alocated to me at Lohen on monday and dont know whether to have the pulley changed or go for janspeed manifold and de-cat what do you think?

Being as though going de-cat is illegal in the UK I would suggest the pulley (plus its a far more cost effective per bhp mod than a manifold). Push came to shove then and you wanted the noise (I love my sport mani! ) then I suggest one with a sports hi-flow cat, not a de-cat, so it will pass emissions and road/some track sound levels and be legal to drive on road. I run a milltek mani/cat and exhaust but have heard the MTH one is pretty nifty. Janspeed is very good too but I think they do a sport cat version to maintain legality.

Sorry i should say de-cat is illegal for road use in the UK not illegal outright

three hours you could do both imho get the pulley £/bhp its so much better and you can physically feel the difference.

I'd do the manifold. upgrade the scharger pulley on it's own is a bad idea in my view - also need the IC to be upgraded, don't want temps running high.

If you change the supercharger pulley do you really need to upgrade IC. No mention of that on GTT site regarding their 210BHP upgrade.

I would agree with the latter,on the works 210,gtt 210,birds/hartge 210 etc the stock intercooler remains.
I would go with the pulley as its more bang per buck,tho i love the note on a sports manifold.....but that can wait.
There has been a lot of discussion on the pulleys and it is recommended having it mapped at tjhe same time, there is absolutley no problems in changing the pulley but it will need a new map,whereas with the manifold its not essential.You said it was going to Lohen and from what i know they are very reasonable with their pulley and remap upgrade

No problem then. You read, you learn.

Still think that the manifold is the way to go, esp if you have a milltek zorst already.

If you have 3 hours, then it may be possible to fit pulley & manifold - more more more

Whilst a manifold is an enhancement that you will enjoy, the pulley swap is what really really changes the charachter of the car. Pulley mod first every time..... suggest 17% reduction.

You can't say that it is the pulley that really really changes the character of the car - have you not heard the whoosh from the intake or the bellow from the zorst or experienced the handling from big brakes or coil-overs or the change in styling to the exterior or interior, or delivery of power from having octane booster in the petrol tank.

Hmmm - don't agree that it is the SCharger Pulley that is the main character changer

Perhaps you should take yourself back to a standard Cooper S - with less than 171bhp - and realise what a slug it can be in 5th and 6th gears.....

Done all the above, and yes, the greatest single change was the jump from standard to 210bhp.... achieved wuth a SC pulley and ECU upgrade.....

Everything else enhanced the experience, but the basic initial jump is what matters. Whats the point in a expensive manifold upgrade if your car is otherwaie pretty standard ?

Im with Tony if you looking for power 17% pully massive difference and the best bang for £ you can get

[DaFlake]

Just installed a 15% pulley this morning and I have to say that most people are right that this is the best mod for the dollar (pound) that you can get. Pulley is definetly the way to go. Took me 3 hours to install and I would reckon that a person that has done this a few times could do it faster.

i personally would not want to change the pulley myself, but i think the 210/220 conversions are the way to go.

Although i myself ( surprised still ) am still very very happy with the standard 163bhp the MCS has as standard. And while i am happy with it i will keep it standard for as long as possible. Knowing that in a years time when i eventually get bored i can just slap the 210/20 kit on and effectively have a new car.

The only things i am changing are service parts and intake and exhaust as i want the beefy sound. It really is one of the first cars i have ever bought where performance has been just right out the box.
