My Mini is
JCW Model 03

Do I have to install CrankShaft Pulley ?

or
Do I have to install the 15% or 19% Pulley ??


Or Both Of them

and

Q1:How much does it cost me to install pulley only ??
Q2:How much does it cost me to install crankshaft Pulley ??
Q3:How much does it cost me to install the Air Intake ???


Sorry For Bothering Guys

 

You don't HAVE to install anything. A JCW MCS already has a 14.8% pulley, so a 15% pulley is basically no change at all. If your car was a JCW when you bought it in 03, you could upgrade the intake to a JCW intake which wasn't available then. Not sure on the cost to buy, but installation of any intake except the VGS is pretty easy and fast. Meaning you can do it yourself or have it done pretty cheap.

 

a ROUND pulley Sorry couldn't help myself.

Tell us what are you looking to accomplish?

Any major brand will be fine. Defined major brand *ALTA, M7, Helix, etc.

Pulley size: Depends on application. I'm running an M7 16% pulley, which can be used with the stock sized belt, and no other mods. 17 and 19% pulley's require a smaller belt (I would replace it with a Gatorback anyway), and injectors are recommended. JCW is a 14.8% pulley, so like Argo said, it would be useless, and I think you wouldn't see to much of a difference with the 16. If you DD the car, and don't track it, I would go for a 19%, if you track it often, then stick with a 16 or 17.

Crank pulleys: I've never delt with them, but 2% oversized seems to be the most common. There are plenty of people running all sorts of combinations, including I think a 19 with a 4?

Intake: Intakes are easy to install, unless you are planning on going big, such as the AGS by M7, then things get more complicated. There are a whole lot of different intakes, which produce different sounds, in different spots. IE: You can hear the ALTA intake more from inside the cabin, whereas the M7 is a "crowd pleaser" because it's louder on the outside of the car. Intakes such as the HAI (Hot Air Intake), CAI (Cold Air Intakes) like ALTA and GTT, etc. are easy to install, and you can do it yourself.

Installs: Do the Intake yourself. Pulley will cost you ~$200-400 would be my gestimation, and I would think the crank pulley would be around the same. If you DO go with a crank pulley, I would also recommend getting a tension stop (http://www.myminiparts.com/proddetai...rod=TSB&cat=7). Keep in mind that when you go with a 17 or 19% pulley and an Intake, and Crank pulley, you might need new larger injectors as well as an ECU remap.

Hope that helps a little!

Actually, the red pulleys will go faster.

Just get some nice CR paint and paint the JCW pulley

 

So wut i need now to install is Crank Pulley 4% and Pulley 19% ?? And do i have to change the belts ?


Air Intake ?
Which is CAI (Cold Air Intakes) like ALTA ??

Is it important to install larger injectors and an ECU remap with the pulleY ????

sorry guyz for bothering u .. cuz i dont know anything about Mini cooper Tuning

 

Alright, the goodness of pulleys.

My story: I got mine installed by Helix for ~$400. It's a 19% pulley, and that is a tad pricy for a pulley installation. Since I had no experience of doing this on my own, I was willing to pay for the expertise help which Eric@ Helix gave me. Shop around and see if you can find a better price from someone you trust, that's the trick. The car is MUCH faster now though.

As I said, it also depends on what you are going for. If it is just for speed on the streets, I suggest doing a 19% pulley. I know it says an ECU map and injectors are recommended, but they are not on my car and it still runs fine. Although, don't do one without the other, as Eric has told me it can break the limits when running the car (ex. don't get injectors without and ECU map, or get an ECU map without injectors). But if you already have the JCW injectors, then you should be A-OK. For the ECU map I would go with the GIAC ECU flash, as you can always flash it back to the stock settings. i've heard iffy reviews about pricy UniChips, which are what some will recommend.

Eric also told me that there have only been three failures of his pulleys (just the belt breaking mind you, nothing else. new belt is ~$25 to replace) All have occurred on the track and they have been a 15%, 17% and 19%. So either way you can not go wrong. I would suggest calling Eric at Helix and he will tell you EVERYTHING you need to know about pulleys.

The air intakes should say if they are hot, cold or both. This is a very easy mod to install, and correct me if i'm wrong, if you go to Helix to get the pulley installed, they will do the CAI for free as well. That is, if you really don't have a clue as to what you are doing. I'd suggest the Alta intake, or the K&N Typhoon.

Good luck with your decisions

 

heheh sorry for this Question.. cuz im stupid on thies things.. :D
so how can i know that my enjectors are JCW to not be replaced, cuz where im living, we dont have anywhere to tune our mini accept the dealer :S

 

where are you located?

Yes, like silverbullet said, at our shop, we will install a CAI for free if installed at the same time as a pulley.

If you have any questions abotu what would make a good set up feel free call Eric at our shop. The number is 215-739-8800. I would try calling today if you are going to since he will be at SEMA from tomorrow until Saturday.

 

Actually I live very far away from u : (
I live in Bahrain ( Middle East )

So do u think if i installed the crank pulley 4% with 19% pulley on my mini JCW. It will give me more performance that i can feel there is much more power from b4 ???

Do u think is it warthy to change them ??

 

No. A 19 and 4 would be useless, I would go with a 17 and 2 or just 19. Once you start getting up there, the heat generated by the SC will soon stop making any gaines, thus it will be useless. Basically it'll spin the SC so fast that all you will be doing is making more heat, not power.

Someone please correct me if I'm wrong.

I think you are right.. because somebody told me the same thing.

so wut do you recommend me to install to my JCW ???

Its Stock .. I want the 1st thing that i have to install

 

The usual reccomendation is a 2% crank pulley for people with a JCW.

"The 2% is a perfect upgrade for the JCW, and it responds well - 8 hp and almost 4 ft/lbs of torque."

 

Ok = )
i think i have to go for 2% CrankPulley..

but do i have to order the Belts and Tensioner Stop Bar ???

 

You will want a shortet belt. Someone else will be able to explain which one.

 

You will only need the shorter belt, however the Tensioner Stop bar is not ever required, but is highly recommended in case your belt snaps. A $20 part could save you that shiney $150 pulley.

Those who make cars, like BMW, use damped crankshaft pulleys to protect the bottom end of the engine from catastrophic failure. These pulleys, such as your factory crankshaft pulley, have a rubber section around the hub to damp out engine and accessory vibrations that can set up sympathetic vibration in the engine.

Those who want to make money by selling you their aftermarket crank pulleys will tell you that their undamped crank pulleys are safe for the engine. No aftermarket crank pulley has the elastomeric damping that protects the engine like BMW chose to do.

You decide whose engineers to trust...

I suggest that you use a 19% SC pulley and let it go at that. You will wear out belts faster due to the smaller pulley diameter, so get a spare belt at the same time.

 

I have considered putting a 2% crank pulley on my JCW but decided against it for the reasons that were well articulated by OldRick. BMW use a damped crank pulley for a very good reason. However, if you do opt for a larger crank pulley then you should also increase the size of the alternator pulley to prevent the alternator from over spinning - see Craven Speed dual pulley set http://www.cravenspeed.com/index.php?productID=20

You also need to consider that air temperatures increase the faster you spin the supercharger, hence the need for an intercooler to cool the air before it enters the engine (cool air is denser than hot air). People who use their cars on the track or are aggressive road drivers often find it beneficial to increase the size of the intercooler. If you fall into either of these 2 categories then you might consider doing the same, especially as you live in Bahrain where outside air temperatures can be very hot.
