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

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.

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....

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

good buy the 2k is the current price

+1

around 2100us for the 8 or 10cm, same as what i make but mines crap :

dam good turbo dude played with a few if them built to last like only MHI does.

Have a word to GCP/POSSUMS before you continplate buying a Blouch Dominator 2/2.5

only that if needed as for the rest inside its goes into the bin, if they actually copied the oem unit size for size but they come up with their own sizes that dont match anything else. as above you get what you pay for and if thats your budget then suck it up when things go wrong.

wont touch any chinese stuff wont add why might upset mr simon again

opens a can of beer

pulls up a chair gets out the popcorn

its illegal to have catch can that vents to atmosphere, oil to air separator is whats needed.

Sorry i dont give prices over the forums or pm go see your closest turbo shop they should help or point you in the right direction as long as your sure thats the issue. If they cant fix the turbo there will be many many many other shops that can.........

FUNKYTOWN !!!!!!!! seriously steve W T F.. a member is trying to throw business your way and with out anyone else saying a word you manage to come across like a complete twat. your forum etiquette is way off the mark. Also FWIW - i think your work rebuilding to factory spec is totally a-grade stuff. I wont take over this thread but based on you and ya mates you wonder why i answer that way? Dont be a hypercrite Jon read your past posts any praise from you means nothing go kiss someone else's butt and eat s*** ya tosser > Ive never ever been on forums but to help not chase work,thanks to speacial people like you and your mates i wonder why i dont anymore. So thanks to drop kicks like yourself and ya mates others miss out on PROVEN info. As for above yes you can rebuild vf's replace seals and many other things etc etc i do many per year You cant pin point what the smoking issue is without seeing in real life, White on start up from cold normaly moisture,blue oil burnt inside engine, white after 10mins plus running turbine leakage. OIL SEALS DONT JUST BLOW !!! LEAKAGE IS THE END RESULT OF OTHER THINGS GONE WRONG. Take your car to nearest turbo shop as such and let them have a look before you turn spanner based on unsure advise on forums, im sure theres many turbo shops around that'll repair the turbo if needed.

the best turbo is what you want it to be rebuild vf's? na cant be done even thou i did over 50 last year but dont take my word for it i dont know shit

first off this was never said "In each case the turbo was custom tuned to peak it's pote.ntial" it was meant to be back to back bolt in no other changes guess that was over looked : Secondly the way i tune isnt just going for pike torque( you would run out of power pretty guick just using that method), you would measure the backpresure before the turbine and compare that to the comp end to establish what fall over first, did it need a change in cam timing,ran into knock( if were talking about the same tuner i spoke to knock was an issue) etc etc also temp intakes also so a better picture than whats being shown here. Torque drops off well before peak power as per most engines unless your running a t51 thus your not tuning to its full possiable outcome. The compwheel isnt that big 68/47.5 compared to stock its bugger all bigger as for the lag the graphs ive put up shows a differant story, again if the units gate isnt right or rate of gain for the boost controller etc etc to which if it was a link there boost control isnt very good even link say its 75% ok will effect it.( i have customers that run PRS and they dumped the link due to this issue) The graphs as ive shown backs up what we spent so much time testing before joe blow got to use it,many have a many are very happy. I send alot of bolt on mse units to aus to where they take out the avo so called bolt in and replace with mine due to the fact they lack responce, the head tuner for motec Paul has tuned afew his words were it was more responcive than stock give him ring dont take my word for it. Now i did ask you to explain why guys with stock vf3x cant get close to what others are getting stock even with changing tunes, this is pretty comon with subs so just maybe theres good ones and bad ones and i or the tuners i use dont make the cars we just try to our best with what rolls thru the door. I have seen many times car "a" stock run against car "b" with good mods done get its butt kicked,you could bring driver into this as with other possiable errors but doesnt explain with the power differance why it couldnt even match the same topend yet the dyno tells another story. Big power figures of a dyno dont always reflect a fast car,the backcut has been standard practise for many years to help aleviate backpresure for a stock turbine hsg or wheel as im sure your awear they all share the same turbine wheel and factory or after market dont have a bolt in rh6 turbine which would be nice. The back to back testing with or without a backcut we found a small increase in power but what it showed the most is the reduction in backpresure reduced exhaust temps allowing more timing to be used be knock and everyone knows subs are prown to knock at the best of times and theres many posts on here asking how to remove it even on stock setup. We found tuning grp n that tuning each cly( using motec) we found one gave the biggest isssue and adding fuel or ruducing timing we could lean on it harder and i dont mean boost, but repeating that for each cly we gained 30hp for no more boost. I think we just has to be accepted that each car responeds differant to the next, if you use my upgraded on a car struggling with a stock vfx to go past 210 then gets 225 with mine but wont go further its still a gain regardless even if it didnt hit the 240 mark so i guess theres alot more to it than the turbo. I think alot need to spend a week in a dyno shop watching and seeing what realy goes on and how we have to try and make a silk purse out of cows ears,thus with all these net pros that are such critics i would love to see how they deal with issues and the answers to fix them and not on a forum. The answer your after based on whats meant to stock from car to isn the case, we have pulled down many engines to find from side to side the deck heights were differant chamber cc was differant and cam timing marks stock didnt line up being half a tooth out, now the guys that do ken blocks engine make adjustable idlers to allow a slight adjustment to put things back to factory and seeing another 30plus hp for there efforts. And theres meant to be no differance between engines? yea right would make a good bill board. So you want an answer? maybe your not seeing it or looking for a easy one well there isnt just keep testing and trying is what everyone does. So lets take your v34 turbo off and put it another that cant make anywhere near yours, wonder what would happen try it and lets know but everything has to be the same no retune just to be fair. Usless info here i spent the afternoon at alltech we went thru all the OEM documents from Garrett, holset, mhi, ihi,borgwarner and couldnt find one statment referring to the compwheel to exhaust wheel ratio to what is max allowed. So we measured my little upgraded thats been said the wheels to big and that was a .77 ratio, stock was .87, 3071 was .8, a 3082 was .7. There is however a ratio for manufactoring a compwheel that borgwarner dont recomend you go past of .8 theres no refferance to anything else unless you guys have access to documents the biggest turbocharger place in nz doesnt?

I apologize net is great for interpriting how things come across, Concerned about what? its 8kw short of what its max is meant to be for that and how its tuned when it leaves my shop is out of my control as your seen by a back to back we did that wasnt the case nor was the v7 and v8. Im repeating here each turbo regardless or whos will have differant effects to some point on any vehicle, so in fairness you would say 8kw isnt that bad as for the mid range who knows how that was being controlled was the gate tied? preload been changed? again regardless of the back to back as per yourve pointed you still have 3 differant units. again explain why the 3076 is 50kw down for 3 psi more? Now if it realy is the same motor theres more than likely something it doesnt like from one to the other, you need to tune the base setup to 90% of what its capable of then change to the next unit and do the same to find the limitations or gains. The little details will make a big differance thus take your pick to which thats the job of the dyno operator to find these. You cant compare a 400hp unit to a 525 that isnt by no means remotely the same( comp wheel turbine and housings totaly differant),52lb/min versus 40lb/min its not hard to work that out. So if we bolt a t51r on and ran the same base tune and boost what do you think that would look like? Theres 5psi differance between the 3 at points thats not an even playing field in anyones books. Every upgraded thats done thats big 16g uses a genuine MHI wheel you will never see the power of a 3076 out of them and ive never promted that, its designed as mild upgraded as s straight bolt in nothing more nothing less. Subs are know for boost drop off on the topend everyone knows that thus all the posts asking to improve then we have others that dont drop off and yet were talking the same stock vehicle with no upgraded turbo, explain that. As for your vf34 looks like a good effort now theres also alot out there that cant get near that result for the same vehicle again explain that.

hahaha cheers in person i just punch people that piss me off saves a ton of typing And those who dont like what i make or say dont use my units and get over it, suck ya heads in and show us hows its done or live inside a pc for the rest of your life cause thats the real world :-* HTR969And this is the end result of a crappy built under performing mse turbo. RIP stacey a top guy that will be missed by many let stace have the last word......

forgive if im wrong but im not awear of any other shop in nz doing what i do but your are correct, the max i would expect to see from my upgraded is 240kw so it was 8kw down yet with his 3076 versus my crap 3076 on 3psi less turbo for turbo hes is close to 50kw down!! must be the dyno or photo shopped dyno sheet.

what mods were done to the v7 - thats bloody good bro!!!! Was on a version 4 STI, just like the one Steve posted of his modified oem turbo, except this turbo was not modified and is making more power everywhere As Steve as recently learned though, you can adjust the dyno parameters to make boost come on early or late, you can also make it read whatever power you like. So we must agree posting dyno sheets is a hapless cause. I also would like to hear Steve's analysis on the three compared turbos (one his) that were tested in controlled conditions as we know dyno discrepacy can be eliminated. Nothing like learning from the experts If your going to turn into total f***wit like the others ill treat you accordingly( i was told you better than the others), as for the comparring turbos if you read just a tiny little bit closer many get differant results from similar setups and alot cant get even close. Based on your analise of these units lets compare the why the 3076 was crap compared to what we did over 300kw and yet we ran 3 psi less? as for the units being close i think a blind man can see theres a 5psi spread between them at differant points and depending on the rate of gain( 1psi plus or minus =?) will can alter that picture dramaticly but hay as you said dyno sheets are a crok so i guess mine is just as much a lie as what you and others have posted. So maybe the reason mine was a tad low is the same reason the 3076 didnt cut it either,it too could be a lemon thus spend 8k or so to make slightly better bargin. Differant or even the same turbo will give differant results on differant cars, heads, cams, compression,cooler,piping, intake,rod angle,crankcase volume,manifold,headers etc etc etc all contribute to the outcome. So take your pick to what could alter the outcome talking with PSBM and afew others they too have had lemons that no matter what you do wont make numbers,get over it and move along or open your wallet. We can only work with whats presented to us based on customers budget to which kills alot of their dreams and expectations, in saying that what would have that dyno sheet you put up looked like if it had a tricked up turbo on it? So lets take them to track and see what it all adds up to or just get over the fact there is differance based on many contributing factors or just screw with the dyno.....A. To which many travel from dyno to dyno to find that warm fuzzy feeling for a result to never take the car to the track ( or write it off on the road to where they shouldnt be racing in the first place) or sit in traffic 3hrs a day with dyno sheet glued to the back window "hay look what ive got" or jump on a forum !!

Not according to the speacial ones on here its the be all end all, but i totally agree with you no offence taken glad someone else can smell the coffee.

hahaha cheers dude you mean my grandads 5 series bmw? na its just all shit yourve seen and that tiny little cheap chinese turbo going on it itll never work like that 600kw holden ute i showedu on 12psi na just all bullshit and hear say. did you have a look at me being a drop kick in me 5hp briggs kids kart? crazysteve.mov imagine if i knew what i was doing and it actually went well? all those tropheys on my shelf was from being a dick, i should apply myself one day :D

No prob that was a stock back to back on the same dyno and day,big 16g comp wheel backcut turbine and thats it. the comment made about lack of mid range responce and power shows a differant story as everyone else has found that used them bar the gifted ones. Any good responsiable tuner or car owner wouldnt be to smart to bolt anything more on a unknown condition engine even with lowish km's and tell the customer "yea bro itll handle more" and has to explain the hole in the block or a run bearing. Its funny to compare the 3076 to someone else that made alot more power on less boost, but as has been said "what's great about the information posted is that it is from the same car, same engine setup, same dyno, same dyno settings same same same Just different turbos". Must be something wrong here but since my piece of shit usless crap mse turbo setup won its class in targa a few times then the problem must be? I will add more engine details on many more ive done including cam timing igniton timing, compression intake temps ramp rates etc etc etc but just ignore it all cause my stuffs shit and i have no idea what im doing.
