Hello,

I'm considering getting a set of light weight pulleys, most likely from CDF racing, just wondering, is there much benefit from the standard heavy ones?

Also, does it need a map? Or is it nothing to do with mapping?

 

no map required, but ive heard the cdf ones arent the best of fit, butcant confirm this as ive never used them.

 

Not sure where you heard that but our pulleys fit perfect

cheers chris

 

I think I have a friend who has cdf one's and they went on fine, I will check,

Chris, how much for a 1997 uk turbo without power steering, looking for black or blue, is it just 3, can I re-use the belt that goes around them?

Thanks

PS, I ordered a TMIC tilt kit last week, not received anything yet, I don't suppose you know when they are being sent?

Thanks

David

 

Hi,

I will ask the wife where the receipt is for that....


We don't do the pulleys without powersteering as the same belt runs the alternator, we do them without aircon...

will drop you a pm in the morning if thats ok as I am just leaving work now

 

i had a set on my car and they fit perfect.

 

oops, I meant to say no aircon, of course I have power steering!! So, a normal set then!

 

Do they make a difference ?

 

There is little weight saving without aircon ,but we can do it... just about to reply to your pm

 

I've sent you a pm, as I have confused myself , not sure how many I need, can I use 4?

 

i got a set on my 1997 sti very easy to fit well worth it

 

How long does it take, was the car more responsive? I think I just need 3, I can only see 3

 

there are 3 pulleys on mine. i had to take off my front bumper,fmic,25 row oil cooler, rad. because the crank pulley was tight and had to use a air gun

 

What the stock pulley was tight?

 

iv got a set and there perfect, CDF's customer service is also second to none !

 

The CDF crank pulley was much tighter than the stock one. I was stupid enough to force it into place so next cambelt change will be a pain.

 

sod that a breaker bar and 5th would of sorted that

 

I have a set of these, top quality and fit perfect .

 

I received a set of CDF lightweight pulleys today and having looked at them I have to say I am impressed by the quality and how much lighter they are than the standard items.

 

You beat me to it Ty! I have these on my shopping list for the rebuilt block.

 

do you use the original bolt from the standard 2 tone pulley ?

 

So,what do they do for performance then?
Have been chewing over getting some,if they actually do something other than look pretty and lower car weight by a few kg's.

 

cdf mite have another customer as im goin to change my timming belt this week so itgs a perfect time to fit 1

 

Guys ,

The stock pulley is actually made from two pieces. Because is it very heavy it has a damper in it ( the rubber piece in the middle) after a few years ( we find around 8-10) this damper is known to split and cause the crank pulley to split in two. We sell quite a few of our pulleys for this reason as ours are from 1 piece and can never split.

The kits are very light, the crank weighs around 500grams compared to 2.5 kilos.

You will noitce a better throttle response and maybe pick up a few bhp's

 

Looks like something else is going on my ever growing list !!

 

I can vouch for this: my crank pulley split and introduced a VERY worrying rattle into the engine note.

Sorted now, but only with a standard one, sadly, can't afford lightweight ones at the mo.

What is the benefit of a tmic tilt kit ?
How much does it tilt the tmic ?

Andy

 

andy,

can you pm me your details , i cant see nothing on my system

cheers

 

It raises the tmic closer to the undertray, for £6 ish, it's definately worth it

 

Huge bump: does the lightweight pulley have a damper too? If not: isn't it dangerous to not have this damper?
