. . . . . for those of you that don't look in the "Group Buy" section.

"Group Buy" on light weight pulley kits.

The Stock size kit consists of a crank pulley @ 133mm diameter weighing 550 grams, a powersteering pulley and a alternator pulley.

The underdrive kit is the same as above but has a crank pulley @ 104mm diameter weighing 350 grams.

If they get an order for 20 the prices are as follows :-

Stock size crank (550 grams) £45 each

Underdrive size crank (350 grams) £32 each

Alternator (50 grams) £15 each

Powersteering (200 grams) £50 each

Shipping £10

This ultra light new design crank pulley weighs just over 500 grams compared to the stock pulley @ 2700 grams. These have been made as light as they would possible go without making them weak, Will fit most models 93-2005 & can be anodised red/blue/green/gold or left as bright alloy finish.

Well done guys we made the 20

First on the list mate...

Now that's gotta get the punters in.

Hopefully where you lead others may follow.

I am surprised people aren't breaking his door down for these @ these prices.

Lol, look out jesus..... here I come ha ha

I know mate, a cracking price for an all gain/no loss modification.

These were on my to-do list anyway

 

What do you gain ???

Or am I being 'doopid' ??

 

You will gain a large reduction in rotating mass of which in turn provide better throttle response. Due to the reduction in weight you will also reduce some strain on the rotating items such as the crank etc

 

Very interested, not sure if mine are the same size though, I suspect mine will be the same as the newage...

Any idea's anyone... only thing I can think is to measure them...

does anyone have the dimensions available?

 

When a pulley or flywheel of a car is lightened it can have a great effect on acceleration - much more than just the weight saving as a proportion of the total vehicle weight would account for. This is because rotating components store rotational energy as well as having to be accelerated in a linear direction along with the rest of the car's mass. The faster a component rotates, the greater the amount of rotational kinetic energy that ends up being stored in it. The engine turns potential energy from fuel into kinetic energy of motion when it accelerates a vehicle. Any energy that ends up being stored in rotating components is not available to accelerate the car in a linear direction - so reducing the mass (or more properly the "moment of inertia") of these components leaves more of the engine's output to accelerate the car.

In other words ~ what fraz said.

Nice reply Mark

 

gone and done it....
