vf22 rounded wheel???

[Guest]

what causes the wear on the comp wheel below? seen a few like this guessing it doesn't do great things for flow. any ideas?

[Stoffa]

A file? Looks like someone has tried to tidy up a damaged wheel

[ADIKT]

I bit of play in the bearings?

[Swindog]

Thrust bearing being worn.

Happened to mine too. Then one day pop at 7000rpm. Snapped a fin. Normally preceeded by a high pitched noise from the turbo area on full boost.

[gotasuby]

Bet you a pod filter was on it, a foam 1 prob

[D-Style]

You could put it on Trademe and say its a "special Mod" to make it boost hard bro.

[MercuryFree]

It's already on trademe on $1 reserve, I was thinking of buying it to turn into a table ornament

[Guest]

its worn right up the wheel not just the edges so it doesnt look like rubbing on the housing...

i've seen pics of a few like this in my search not just this one too.

i randomly speculate meth injection spraying into the wheel but not something i know anything about at all

no ones really comes close answer wise

its called contaminated air as in crap bypassing the filter or no filter thrust bearings in vf series are at the exhaust end and if they fail you wouldn't have a turbo but they also dont have that effect unless it has a shit load of side play.

eroded comp wheel is poor filtering blades broken come from foreign objects or server comp surge.

one of my mates vf23 whines real hard..very much from off boost all the way till redline

worn thrust bearing?

is there a fix

sounds good but gets annoying after a while

So what I said. A shit filter that didn't filter like it should have.

My VF22 whined like a btich from when I bought it on the car at 206,000 til when I sold it at 230,000...no performance change over that time and it still worked fine. I'm not saying your friend's one doesn't necessarily have issues, but it's not a RED ALERT

and some get lucky and that doesn't mean its right if i told my customers other wise i wouldn't be doing them a justice.

the picture about is classified as stuffed and end-float above factory by over .008" is also time to fix

[funkytown]

hot / fast / well used / modified bits on performance cars as always will mean:

YMMV..

like me and my 1 year old brand new unit. win some / lose some.

[pl0x]

Whats a "average" rebuild price on a VF22

fair enough

[Guest]

is it worth buying a shot vf22 cheap for rebuild though?

just whatever condition vf22 i get i want you to give it your special treatment coz ive only ever heard and seen great things about your work.

ps i want a mse turbo ;D

[vorigan]

the problem lies with just that....trying to find a unit and most vf are hard to find regardless the model

i can do most things to them but if the shafts poked there's not much i can do thus prevention is better than the cure.

my last spare vf's are on there way to Bonneville soon to hopefully put more kiwis in the record book, it should make the tv its something some my laugh at but its going for the worlds fastest 1000cc mini

and don't believe all you hear hahaha

[Guest]

so the shaft in the unit in the pic could be fine? if so do you have a comp wheel?

i can get my hands on a seized one too but havent cast my unexpert eye over it

and i dont doubt you i believe, i dont argue with experts as i know what its like when your customer can do your job way better than you...

as much as the vf22 is meant to be the highest flow of all the vf's i find the vf36 far better and doesn't blow blades off over 20 psi, if a unit has seized it depends of the shaft has made contact with the core or if the bearing collapsed and bent the shaft non of these can be answered till its pulled apart

[Guest]

id rather stick with single scroll i know its not best but im young and having a kid really tightens the wallet a lot. ive seen dyno graph of mse vf23 vs stock vf22 and it looks better everywhere

this is only a family wagon but im just used to a lot quicker...
