Vf22 Repairer

[hack0r]

Hey Everyone,

There was a guy in Auckland that used to repair vf22's for the life of my I cant remember the guys name. I have seen it mentioned here, I used search but I cant find the post.

Anyone know someone that can repair them?

Thanks,

[LAZLO]

theres a shop in manukau

[Guest]

Steve Murch ?

[hack0r]

Steve Murch! Thats it, now any one got his number or the name of the shop?

[wrx_lou]

MSE turbos. He still lurks here and other places. I think Funky has his number.

DONT meantion funky in the same sentence as me thanks

Whoevers out manukau try them im overloaded building crap that doesnt perform theres tons of other shops around that will do it im sure

Oh sounds like a sore point here !

Is this in regards to the "back cut" turbo?

I'm assuming that "vorigan" is Steve Murch

I dicussed this topic with the main turbo engineer at FHI ( he studied air dynamics for 10yrs - so knows what he's on about)

He did agree that lightening the turbine will aid spool, but too much would reduce the "effective drive" applied to the turbine and reduce spool

He concluded that this would be a very fine balance between more or less spool

I'm no turbo expert, and take advice where available -

If your funkies wiz kid engine builder for subs RICK WHEELER WORLD #2 !!!!!!!!!then you should know all that and some( or should do ), backcutting has been around for many years in turbocharging for the reason you stated from someone else and the primary reason was to reduce backpressure on the turbine to raise power at the topend reducing cly temps thus reducing detonation( to which subs suffer from at the best of times), and with the status you have why didnt subaru teach you this?

Theres no free lunches you gain here lose there and was never done to reduce spool remember theres no bigger turbine wheels for the vf series as such so to increase flow you reduce backpressure or larger turbine to which most turbo sites will tell you that.

As for lighting the rotating mass it removes about 10grams on the average wheel depending on the angle for the backcut to which rally cars we use 5-7 degs and high hp 7-11degs, this is done to simulate a larger a/r turbine to which isnt avaliable nor are you allowed to change it in grp N or other restricted classes but backcutting is.

A 2-5hp gain as you would know on a grp N car is massive and this option fits the bill.

They now produce turbines with less blades lighter materials and reduced inducer tip height to achive the same thing and guess what? it has the same effect as backcutting strange that!! : then they reduce the a/r to get responce back dont know why :

Also scroll design and exhaust temp have a major part in turbo responce( heat increase responce ) as im sure you well awear of along with state of tune as in timing both ignition and cam that can be run compression based octane all part off the bigger picture of things,to which im sure your mate covered that so not not teaching him to suck eggs.

If you are his wiz kid builder you would also know ALL garrett GT series units come factory with backcuts even thou they dont promot doing it which is abit do as i say not as i do.

Backcutting is a case of every little bit helps when your limited to what can be done no pain no gain but hay its always the turbo to why things dont make power NEVER the car or setup : :

Im no turbo expert but plus or minus 10%( thanks qwerty) on a car making 232 would equal 255 would it not or less? So i guess every car is the same so it must be the turbo.....bill board

Anyway back to the shop i have an overload of units to do cause i do crap work giving crap results i might get one right one day, get your FHI engineer on here and spread his wisdom i dont know s*** and always interested to learn what works in the real world and what turbos he produces and results and a name....

can we say too many variables? and move on...

Sean I gunna make that you sig when I can

Glad you can see that but i guess when you have speacial needs people ( like myself ) on witch hunts ya gotta amuse them.

Now the trick is to work out the variables and make good from it rather than pointing finger.

As far as I can tell the only person saying Steve Murch's work is crap ... is Steve Murch? ... repeatedly?

so ive been told by the speacial ones on here that are on witch hunt for their net/forum life amusment since there on every forum known to man kind, wellington is small place in this industry so info and feed back is easy to come by 8)

I have no problem giving up what little free time i have to help those who are interested without having hidden agendas,as for the rest i do crap under performing working work ive got many proven cars to show that like the targa win couple weeks ago : guess i got lucky with that one ;D

lol . i love you Steve murch ! not in a gay way ha ha. the fact you can turn down work shows you are known as the best around and you have people lining up for ever wanting work done by you . . . . the sarcasm is the best part !

hahahahahah cheers dude im far from being the best( not #1 or #2 at anything apart from racing troheys but hay they were cheap at K Mart) never past that test ticking the boxes tests years ago but its all cheap entertainment but when i run out of work i can allways go back to doing chippy work just part time :D ( sarcasm again )

[pauly12]

i am also after someone that could replace the bearings in a vf22? can anyone pm me some details of a good place. much appreciated.

Yes it is me - Rick Wheeler , World #2 Hello Mr Murch, nice to meet you

I have never professed to know all -are you serious?

Not even you Mr Murch know everything about turbos

But you know more than pretty much every one in the country - which makes you a specialist

I know more in general about Subaru's than pretty much everyone in the country - Did the paperwork / nailed the competition - which makes made NZ # 1 and World #2 since 2007.

I have built many engines . from std to mild to race to wild. Inc alcohol fueled engines.

Fabricated custom fuel / oil / air sytems / rebuilt gearboxes / MT and AT / diff's / ECU's and sorted many problems that often many workshops can not.

I know more in general - FACT.

My post was a simple are you Steve Murch? and was it the prob you had with Funky and a backcut turbine? (which has/had nothing to do with me !)

I dont know you, never seen the back to back test results of your work, and as your the specialist - take your word.

I wasnt knocking you, calling your work shart etc.

I am interested in the process of backcut, had a look at my spare Garrett GT, it is backcut from orginal (very slightly) as you say

Do you change anything with the turbine housing when you carry out the back cutting

Cheers Rick

PS - At 40 I aint no wizz kid, I prefer wise tradesman

[vorigan]

hi rick tis nice to speak with as such but due to the total retards that responed on here i tend to fire back hard until i see they arent dropkicks so ill repsonced accordingly.

Glad you looked at the GT unit but they state dont do it if you ever check out a 3071/76 or 3582r they have very aggressive backcuts, turbine hsg isnt touched unless its a twin scroll where the divider cuts off close to a 1/4 of the flow to the inducer creating issues with the divider falling over or coming away, mitsi suffers from this big time totaly killing hp and turbines.

I call my work shart as it seems to amuse the gifted ones on here makes them fell all warm and fuzzy, whatever blows ya dress up i guess.

As i stated im limited to what can be done on the exhaust side so its an option that adds power which everyone wants, after the units leave my hands either local or off shore im at the merrcy of these people to the results there after short of me doing the whole job, ive posted dyno plots before and after not an excell spread sheet that can be played with but it tends to mean nothing so i dont bother posting the many others i have its more for their amusment than anything else.

I have never never ever proclaimed to know it all i just do what i do based on what the customers wallet is, you want top of the line ill take 20k off you for a unit to which we all know no one will pay that.

I have a setup thats no differant to places like owensdevelopment in the uk but nz is full of diy that want to do it cheap which is the kiwi way i encourage that geat things can come from it look at burt munro and john brittan,we need more of them but for me i spend alot of time developing products that no one here can afford so no point marketing them plus the tall poppy syndrome why would i want to.

Thanks to a few on here that screwed my reputation cant say i care( BUT pay back is a bitc h but ill enjoy every minute of it ) i stopped dealing with the public along time ago thus have 90 plus business i deal with i do work that no one else dares go near i love a challenge like odd ball setups.

I dont know about the people you deal with but most sub owners i deal with are great guys and are over the top happy to clear 200kw wheel not everyone wants 300kw monster cause they know the turbos the cheap part.

Side note alcohol engines are dam good fun to play with.

Out of interest based on your rating as such why arnt you snapped up by a team or people like possums? knowledge is hard to come by at your level.

your 40? got a few years on you dude.

the thing ive learnt over the years "you get what the motor desides" not you regardless of your wallet.

but i seriously dont know crap and been told i build under performing unreliable crap, guess wont have them as a customer bugger ;D ;D ;D ;D

i wont paint my own wagon to how great thou are long past doing that just deal with those who are serious about what they want

[Guest]

Had offers from two AP teams, but at 40 have spent enuf years chasing cars/ girls and booze

Settle down time, and chase one girl (the wife ) and do cars for fun

As for Possum's - umm never spoken to them nor been appoached by them - and in saying that like life south of Bombay too much

I come on here to help guys but do get a little heated at the red-necks ( just a couple on here) just trying to flame me because I have a tiltle

So funny to baffle them with so many facts - they soon stop typing and move on to the next thread

As for Kw atw, it's just a number. with subaru 2.0 and 2.5 and I know that my 250kw eng will be faster on a tight track than a 350+

I build my engines backwards - work out rpm / gearratios etc and build an engine to what I want it to do

I then do airflow clac's and sort turbo size, and then have my Garret guru double check

Will pm you my email and chat further there

cheers Rick

interesting when these gurus run out of things to copy and paste, since nz and aus cant purchase repair parts for gt anymore its makes my ceramic replacements for them somewhat popular, and you mean there places after the bombays? :D
