Question : I AM interested in
replacing my Kelisa's three-belt pulleys with the after market alloy type.
I understand that it will be much lighter on acceleration compared with using
the original metal type.
Is it a good idea to change ?
Answer : The alloy pulleys will definitely look better but your car is
not going to go any faster !
I cannot see how much weight you can gain by the replacement of these parts
but of course, the people selling it to you will show you documents to say that
this is so.
