Pulley Sizes

[Charg'd]

i was just wondering, wat is the smallest size pulley you would recomend for a standard engine with pacemakers extractors? it already has a yella terra series one snout, its for my car, a Vt XU6, the pulley i have at the moment shows 8psi on the gauge unless i accelerate hard & then it shows 10.

Personally, without cooling and tune's, I would'nt dip below a 10psi pulley.

what he said

Also you can run a cam and smaller pulley

[TappetHead]

Yep.
You would need to tune it or cool it to be safe with anymore than 10psi.

[Charg'd]

wat size is a 10psi? as in mm?

[krazyboris]

10psi pulley is 86mm

C'mon Cool it you know you want to then you can go smaller pulley.

Hi every one i just measured the pulley on my car, its 90MM on the highest edge of were the belt runs. What sort of boost would this be?? I bought a second hand snout out of the trader and the dude told me it was a YT snout with a 10PSI pulley i think ive been jipped.

It would be 86mm on the bekted section which is where the belt runs. Perfect. Just make sure the intake is getting good cold air and your plugs and oil are good and it should be o.k.

I recently changed the plugs on a customers' modified L67 to cooler ones and it responded very well.

Yeah 87mm is the biggest pulley we make and should deliver about 10psi.
Standard factory pulley size is about 96mm

what about the 82mm pulley would that be too much for an XU6?
cheers

We don't recommend an 82mm unless you are getting a tune.
Cheers.
