Found out about these from a link on the WRX list http://www.gofastbits.com.au/product/pulleys/pulley.htm

Anyone know anything about them, any good, bad points etc ?

Never heard of them before....

 

I've got a couple of them in stock John.

They are lighter and smaller to reduce the reciprocating mass, and you will need to buy different drive belts for them.

Haven't had time to put them on yet, Think I'll fit the Blue ones.

Will tell you more when I've tried them.

Just get 4-5kg taken off your flywheel.

Losing 0.5kg at 50mm radius is nothing like losing 4kg a 275mm radius.

Thanks Mike - wasn't really interested in fitting them, just whether they made any difference or not. I'll look forward to your review once you've had a chance to evaluate them.

 

Less is more.

 

More or less...

 

From you Mike maybe!

 

I didn't bring the topic up, or offer anything....... but now you mention it ..... err Yes actually.

 

Yeah, me too

 

I'm not until I've tried them on my car though?

 

Is that pulley solid or Dampened? If solid, don't do it.
