Fair enough, most get 210 tops from a stage 1 unless they are on optimistic rollers. It's funny when you see rolling road days and people who reckon they have 230 find out they actually don't

i was shocked when i first seen mine that is why i went for another rolling road day at scooby clinic in chesterfeild and i know theres is bang on as they built my track car...

I've heard of a stage 1 making 230 but that had a faulty n75. Lucky you.

and new garret waste gate..fitted

how much was this? did you get any performance gains? and where on the 1.8t is it located?

No faulty parts on mine ,what ever it needs or I want it gets,As long as the wife don't see the bill all is good (cause if she did she would kill me)

Dunno how much they are retail, but a wastegate actuator costs about £3-4 for turbo manufacturers to buy.

Also Garrett don't make their own actuators, it will probably be from Helical Technology or Gits Mfg. So I'm guessing Mountie just means it came off some Garrett turbo.

Fitting the wrong actuator will probably only cause problems, as this engine runs a dynamic wastegate control system, using a PWM valve (N75). So the ECU controls the boost, by only sending P2 pressure to the actuator when the MAP sensor sees the pre-set boost levels.

The ECU relies on the fact that the wastegate valve will then open, based on spring characteristics and diaphragm area. If you change the spring pre-load, rate or diaphragm area, you will effect the operation of the wastegate. So you will either cause the turbo to overboost/overspeed (great for power, until it explodes!), or you will cause the valve to vibrate on it's seat (at about 4krpm it'll vibrate at around 270Hz, so won't last long!).

If however the actuator from the Garrett turbo is structurally the same as the one on the KKK unit, then you will have no problems. Or you could just get lucky with your actuator choice, and get one that works fine.

What peak boost are you running Mountie66?

230+ stage 1 lol :rofl:

jesus bodge where did you learn all this!!

bodge works with turbo's so he should know lol

:thumbup:

230+ stage 1 lol :rofl:

Yes it is real I have the papers to prove not only that I have naf all to prove to you or anyone I simply posted what I know as a fact I have spent alot of time and £££ on my car so I know what it is...I have been around performance cars for 20 years have raced for 10 years of it and still do....This is just a toy for me that is it I thaught I would do 1 up to see wot there like...I am currently doing alot to it I want to get 300 or so out of it and I will do it not really bothered what it costs me... As for boost it runs at 1.6 bar and the wastegate was matched for my turbo that is all new not even been run yet so when I get it all done I will post all pics and printed docs to show what I get.should be within a couple of weeks all being well.

23psi is a lot of boost, most stage 1 maps go to 19psi tops, guess this is why you have seen 230bhp, don't fancy your turbo lasting too long. Would be a good excuse to get a hybrid when it does go pop.

Never, 8 mths now of heavy driving not a problem.... 5 trackdays in there to

You have been lucky then, as that is a very aggressive boost.

Most mappers don't even take a stage 2 over 18 PSI.

My REVO 2 is 18 PSI running 226 BHP and 261 Ibs torque. The KO3s runs out of puff when limits of 230BHP is hit.

Most mappers will take a stage 1 to around 210 BHP max.

You are doing very well with your motor to reach that figure on a stage 1.

Ya I know that but if you read into it more I am in the mids of changing turbo and lots of other things to so it will come in higher soon like I said I will post pics and info up when I am completed it

I know you are and have read your thread so yes agree not really the figure you have now means much as they will soon change when you have completed your next phase.

The KO3 hybrid is probably my next move so be interested in your project when completed.

cheers

probably are hitting that with that boost

aggressive is the word is it peaky???

hybrid is a big jump and is amazing trust me

p.s if you want a true 300 then the k03s hybrid is not the turbo you want

not using ko3 using garrett

what garret????

imo the best setup for track and 300+ is the k04 hybrid has seen 330bhp so far with minimal lag in comparison to laggy garrets on the 1,8t

i take it you will be doing diff etc etc??

yes having dog box built now and bigger drive shafts

dog box nice getting a ppg for my scooby standard 5th cut 1 to 4th

if you are targeting 300 i would suggest the k04 hybrid with water meths as its has next to no lag

or go straight to a gt2871 or gt 3071 mapped down

what engine mods are you doing ?? i.e rods are a must

Pistons rods the lot is getting done £7600 for engine build it is done and sat in my garage now...I have been waiting for ever for my gearbox and drive shafts that is what is taking the time....I had a dog box on my scoob straight cut 1 to 4 standard 5 ran 60 plus track days with it never had a problem.. mine was ppg and so is the new one..my turbo is the t 28 they say it can get 340bhp upwards so that will be fine....

with the engine fully built and running that style of box you will be far better off running either the gt2871 or the gt3071 imo

have a chat with badger bill he really is the man in the know and will prob advise the same as the turbo wont be streaming but will be making same power with less boost etc etc

ppg is awesome hard to break wich is a good thing guys running 600+ on them on scoobys with no issues and sound awesome lol

£7600 for the engine build,what spec did you settle on to arrive at that figure.top spec engine build with inlet (apr or sem) manifold and cnc big valve head should'nt be much more than £5000,unless you are including the gearbox in that figure.

:yes:

you what???? parts alone where nuts never mind the time to do it gear box is another 3500 with new shafts engine price included the turbo to though.....god my scoob I spent £15000 for my build on that it was running 550 bhp 600ftlbs it was a right tool....

you could easily spend 5k just on engine parts buddy without it even being built lol
