As title,

Also what is the standard boost pressure?

Ta!

i think i am right but willing to be corrected

standard boost presure is .7 bar max

and you realy dont want want to run it higher than 1.2 bar on overboost it should then fall back to 1 bar

chris:)

Or in english 10 psi or thereabouts for a standard car

That can go up to about 17-18 psi but as chorsley says It can't hold that

Others may have different views and I'm sure we will be corrected

Well mine has been running 1.4 bar for nearly 2 years and is fine really depends on the type of Map and equipment ie exhaust n stuff you get to go with it

I stand corrected

Our demo car ran 22psi in the mid range and dropped back to around 17psi at the top end.

Mine peaks at around 17-18, falling to 15psi.

Would like a bit more though

Standard is 9 psi....very tame!!

Tops for the KO3s is around 22/23 psi, however as stated above it cannot sustain this due to the heat build up and poor design of the turbo housing.

A good FMIC will go along way in helping you hold the higher boost levels (along with a performance d/p and sports cat!), but the higher you push the boost the more 'spikey' it will be.

Most that hit the high bhp levels (240-250) only actually hold it for approx 1500rpm, i.e. by 4000rpm they've dropped to around 220bhp and by 5000rpm only 190bhp etc. etc.

im sorry i cant agree with this statement if you put a front mount on a ko3s car it will drop boost pressure as the volume required to fill a larger intercooler is higher (obviously)and the ko3s is just to small to increase the boost levels above 22psi ish with a standard one.

Front mounts work ok on k04 cars but even so you will still see lower boost levels once you change from the original intercooler set-ups.

If the car in question is mapped well there is no need to change the intercooler on a standard turbo set-up (england is generally cold enough)

Its basically all about flow or lack of!

:popcorn:I'm in for the night now lol

Wouldn't that depend one the size, design, pipework etc. I say this cos I have a dyno plot showing 250bhp at silly boost through FMIC with a K03s on my old car. :confused: as I could not get these figures with the standard IC.

What boost pressure's where you running? also i bet it didnt make good power high up the rev range!Still if thats what you made thats what you made.

How much would you like to bet (only joking). Made power all the way to the limiter. Quite a well known car on early Briskoda. Can't remember boost levels, sorry. Trust me when I say that the ABD front mount on it made quite a difference. Ask the older fret on Briskoda about it.

Being the "Older folk" that my now, ex mate Des mentions, perhaps I should comment.

I also have a remapped Octy vRS with the ABD Racing FMIC, and it really does make a difference, it holds boost all the way past what was the limiter and beyond, and what ever the weather it never suffers from heat soak. Des will confirm the very low inlet temps (20c) at full chat if fourth when ragging it for Vag Com in the summer in the heat. Also no turbo lag what so ever, as Snoopie will confirm when driving Briskly.............

Ran 238bhp and 246lb ft torque at Marlins last year, with a max boost of only 1.02bar, with graph to prove.

This year ran 221bhp and 248 lbft torque, with the plugs misfiring at 5100 rpm, so the sensors pulled the timing back at those revs, would have been very good figures if it had run to full revs.

Whilst very large FMIC's may cause a problem if not designed for the car, I can assure you that the ABD Racing FMIC does everything it says on the tin and more.

The turbo lag, if much? Goes unnoticed... Could also be dependant on the remap to suit the Intercooler, and how does it substain the power? With ABD.

F1btn As a tuner, if you were to max out your K03s turbo on your Octy, the first thing I would of thought you'd have done, is not only make useable substained power, but reliable power also. Surely, if you run high boost pressures on a K03s, with no FMIC, your turbo will go pop shortly?

Ok well to answer some of the questions a fmic was the next thing on the list to stop the car pulling timing in very hot conditions (so it was losing power at those points) but the car has done around 20k running ph2 c-code software and peaking at 22psi with no problems and is still being used almost daily by its current owner (gary @piper cams).

The car was as drivable as it was when it left the skoda factory in fact id say even more so,yes the turbo is put under a lot more strain but good oils and letting the turbo spool down and cool after a spirited drive meant no unusal problems.We sell forge fmic for these cars anyway but on here so do forge! Anyway im sure the abd fmic are very good we used to sell there products some time ago when i had a g60 golf but thats another story.............................................................................................

My car has a standard turbo setup with CAI, Forge recirc valve and Blueflame cat back zorst, its an ex police so I believe it may have been mapped/chipped - I'm gonna get a power printout next week so I know for sure, so what boost could I run and whats the best way to get it?

I'm after a bit of wastegate chatter but at the mo theres none, so maybe its only running standard boost?!?!?! Not really sure its just been a work mobile up till now, but now I want a bit more punch from it!

Cheers!

Dont think increasing the boost is going to make any difference in wastegate chatter i'm afraid.

I may be wrong though.

Technically speaking wastegate chatter is a bad thing it will kill your tubro prematurely. Unless of course your a mutlinational rally team with loads of turbo money (which is why rally cars do it and the team doesn't worry) Or so I am led to belive but I may be wrong..................Anyone want to correct me feel free.

Hello i actually mapped an ex-police car yesterday and that definately wasnt mapped!

Wastegate chatter only occurs when u reverse on the octys for some reason you cant get a standard ish car to chatter im afraid as you need to run one without a dump valve or have an external wastegate! We can do a ph1 custom-code with the car set-up as is or you can have a ph2 if you put a blue flame or milltek sports cat on it which should give you upto around 240bhp and 20-22psi of boost but i would recommend sticking with a ph1 as the ex-old bill cars tend to be very well used if you know what i mean!!!!!

ta tar.........

oops i didnt say you cant run a standard octy with out a recirc dump valve,before i get accused of encouraging people to make there cars fault code!

should give you upto around 240bhp and 20-22psi of boost but i would recommend sticking with a ph1 as the ex-old bill cars tend to be very well used if you know what i mean!!!!!

ta tar.........

Have you got any graphs of the quoted 240 hp?

mmmmm sounds goooood. I have a standard vrs with full blueflame could i get 240bhp too??

Or is this guy just dreaming

May I ask if you are actually running a K03s at 22psi for any lenth of time other than a boost spike........have you got a graph to show this.

Yeah I know where you are coming from mate! Its been used well!

I'm gonna get a Blueflame sports cat anyway soon so I'll see how it comes out on the dyno as to whether its been remapped before I put that on. Sounds like it might not be then!

Thanks for the help, time to get saving up for a remap then!
