Intake looks good mate.
Powerbond 20% underdriven pulley. Can you explain a bit about this for me mate? Had a bit of a search but found nothing relating to the sv6.
what do you want to know?
What gains do you get from having it? Performance and economy.
Is it something you would have installed for you or can you DIY?
How much did it cost if you don't mind me asking?
Good gains in performance in terms of how fast the engine revs out. underdrives only really work on manuals though they don't gain much on autos. can't remember cost mate $300 installed i think. i think the under drive helped a bit on fuel but a cai will help more. i can get 6.8 on the highway.
Got a 3.45 diff fitted from a ss manual one of the best mods to date.
hi mate where did you get the power bond balancer from and fitted ?
cheers nick
hey mate i was wondering where you got your boot lid liner from?
any Holden spare parts counter.
