I get them mixed up for holden v8 apparently 2 kinds only meant to use steel street version????

Got to look it up one day as probably got wrong one on my 355 knowing my luck.

Are you asking me?

You and anybody else is welcome

Mine is probably a bit different because it's OD, so yes more heat because more powa because the blower turns faster

The only complaint I've heard about with the UD pulleys is that sometimes the alternator doesn't spin fast enough to charge the battery properly (25% UD is probably bad for that). That was years ago though so not sure if it's still an issue with the newer designs. Guess it also comes down to the type of driving you do, if you idle around in traffic all day than it's probably better to only use a 10% or 20% ud pulley etc.

Thanks for that.

I`ll get the 20% one (pic on the front page)

My last question fuel economy.
I`m going to drive the same as I always have.
So will a see any big difference?
Everyone welcome please.
Thanks everybody for your help.
Cheers Pete

It's hard to say. On my old VN V6 T5 I saw an improvement but then on our VS V6 auto no change at all with the same underdriven pulley setup.

 

[VS_Pete]

I didn`t think much would change thanks.

The big question is will it upset my tune?
Or Is it just a add on?
