Robs74, if you can get hold of one of the powder pulleys for zx2's, supposed to be the smallest and I believe it was dyno'd with significant gains. At least moreso than the others on the market. Might pop up used on teamzx2.com. Powder hasn't made them in a while.

Talking

curry crazy read on this thread, I am contemplating CFM's or Massize's purply purple UDP. Good read.

According to many, SRI, front upper strut bar's & UDP are a waste and since I have all those my SVT has got to be the most useless beater here according to their logic.
but butt dyno makes you tink you da fastest lolz!!! ... of course they look good too!

I could but to be honest, nobody else here would understand the math - maybe one or two of several hundred. Mechanical, and fluid for that matter, dynamics are hardly, if ever, what one would call 'intuitive.'

You have never taken the pulley off an SVT engine and spin balanced it. Try it sometime, I promise you'll be surprised.
