LCR 1.8T with OEM K04 & B5 V2 Manifold 325bhp?

ANY gtx will flow a hell of a lot more than a stock ko4

Yeah but would a gtx28 justify the cost when you can get 340bhp with let's face it just a few bolt ons with a k04..

I'm still going the gtx28 because I'm funny like that, but it's just something to think about when people consider the upgrade

That flow at 1.2 bar puts it on a par with a garrett GT2860, going off the compressor map.
HAHA they used to be a common upgrade for these cars

I say to folks often if the low to mid 300bhp range is their desire and they're on a k04 framed install currently, there's no real market for a GT2860 type or IHIVF34 unit these days with the improved spec of hybrids and supporting hardware etc.. TIP,s manifolds, downpipe etc etc
28GTX range will do more of course so there are limits.

Makes me reconsider, would you still bother upgrading to a gtx28 when you can get so much from a k04.

What do you think you could get from a hybrid with this manifold?

GTX2867 can do high 300's into low 400's when pushed so they are significantly more than k04 hubrids.

Ironically, I have an overlay of the lupos k04 hybrid (mutant) and a GTX2867 we did as a track car
Red plot is lupo btw

Will every k04 hybrid achieve this? Nope. The mix of parts on the lupo aum motor has hit a very sweet spot and has mods no other car has which may be part of its high power achieved.(on its gen2 chinafold I made)
For track use I would choose the GTX however.. Probably.. I think.... Hmmmm..
 
The Lupo has a 3.5" downpipe doesn't it Bill? Was it ever tested with a 3" downpipe? Wonder if that is the key to a few extra ponies too.
 
i think people need to remember that this is a massive one off
and do we know full spec yet?
will we ever really know?
most k04 cars wont hit a real (decent) 300bhp

Its maths that its flowing that much air


1 g/s = 0.132277 lb/min

259g/s = 34.25lb/min

lol, maths I understand hehe

comp map showing a k04 being able to do this 34lb flow is my question.
remembering no other k04 we can think of or know of has flowed as much from that 1.2 bar level of boost.
mutant thing.. very spinny spinny - lol

Exactly my point, very hard to justify the gtx now with the way the hybrids are going haha.

I'm going to have a stab in the dark and say that the egts will be less with the gtx? Also I believe it could be pushed a little further than you are pushing it?

Thanks for the dynos though, very interesting. Seems like if you go the gtx you'll want to do work to rev it higher. What would you recommend if you want a 8k rev limit?

Or stroke the motor and the power band should shift left abit and up with the GTX.

I was just looking at Sam Bryants Cn GT2871 dyno you tuned on the relentless v3 and the lupo hybrid flows more at less boost, lol

yep I can push the GTX much more.. but for the track use it was destined for less is more in terms of heat generated and reliability imho. I have turned a GTX2867 up to 415bhp at 32psi previously at customer request.
Overlayed the respective boosts vs the power made for some surprising viewing.

Geez what combination haven't you tried..
Would you consider 32psi "safe", or is it just a matter of time for something to blow up? Obviously on a rebuilt engine with rods. Would you take it to the track for instance?
Given you need to run such high boost to hit 415bhp, I might fork out to get some valve springs to rev a little higher and go the gtx30

I would not choose to use 32psi daily no..
all gets rather hot
Customer in this example was sold the GTx2867 turbo kit by a.n.other well known UK vag tuner for a 450bhp power request. The customer previously had a GT3071 and got talked into the GTX and was from that moment gutted when he drove away from them with only mid 300bhp level.. We logged the car on the dyno, advised him of some mods and remapped it on a return visit to his desired 400bhp+ level.. He has 5 map switching so can run on lower (more sensible for longevity imho) as a daily on the road level.
If someone came here and asked for 450bhp I would not be advising a small framed GTX28xx unit thats for sure. They do flow but have to be pushed to run a lot more boost to get there and that has a lot of unwanted side effects thermally.
 
Thank you Bill. You've talked me into the gtx30, I'll have to accept the later spool. I guess solid lifters, valve springs and maybe cams wouldn't add too much to the build and then hopefully I could rev to 7800-8000.

My only concern is that I've got a small port head :/
 
Yeah I'm actually getting a brand new head for a great price, so I can get it ported at any time. Will I need to get the inlet manifold ported as well?

I'll just go the valve springs then on your suggestion. If I manage to save enough I'll go for some cams as well ;) do you think just Springs on a stock ported head would be okay for 8k rpm? Given its brand new, never used
 
Could you pm me a price. Bare in mind id need it shipped to Australia :/

valves and springs imho, not just half a job.
 
Hmmm.....certainly food for thought.

Wonder what my top secret custom setup will achieve vs KO4 Hybrid, Big Garrett, IHI VF34.....

Well the mystery continues

The owner confirmed its a bone stock Ko4 023 turbo that was refreshed a few years ago.

Its an AMK engine that 2000 miles ago had piston rings, stem seals and supertech inconel exhaust valves done. The car has usual FMIC, B5 tip, R32 dsg intake, Miltek cat back, 3" downpipe and 100 cell cat.

Internally the car has:
Stock AMK pistons
IE Tuscon rods
Calico Coated ACL Bearings

I was expecting the car to have 9.5cr AGU pistons and maybe a billet compressor wheel but nope.

The cars a freak, in a good way

Why did they rebuild the engine just to put a standard turbo back on? Obviously it's made great power but if I was going through all that effort I would slap on a hybrid
 
Reliability / future proofing / peace of mind.

340lbft has been seen from a stock ko4. I think at one point on Mikes car (the subject of this topic) they were at 329bhp / 345lbft before reigning t back to a more sustainable level.

Most definitely beyond the safe limits of any stock lump.

hi guys been a wile hope u all well.

anyone test the B5 gen2 against the pro4
debating wich way to go in my new quest for 350 bhp plus

great results on this freak car lol makes me want to push mine harder now I think head coming off soon for some nice new work and goodies hehe.
 
iam not an expert but all dyno i saw with the pro4 the power starts droping at 6.5k rpm
 
given the gen2 mani has been supporting 372bhp on our own test car on bbt hybrid for > year its kinda proven to be able to support that flow..
NOW, whether the REST of someones build is also up to it is the actual question.

Stop focusing on a single component. No single component "magics" up xyz bhp

rtechs post on std k04 the other week confirms the gen2 can be part of a "syetem" which exceeds previous best in class k04 power outputs.

We've had a trial gen1 mani back for checking and update off a TT racecar ran by Track Driver magazine, and its performed well, remains intact, cosmetically on receipt it looked well ******, but a quick shotblast and it went back to looking as new.. Zero signs of problems, despite serious track use for a race season.

I think it is mostly standard stage 2 sped. It's the turbo that is standard with just some light porting.

hmm, 15 months ago i was slated left right and centre for saying Ron had a stock turbo, i was told that didnt count as it had been (very lightly) ported, the figures were dismissed by many

NOW a car has done even better the porting hasnt been mentioned

This proves one thing, Bill mani, the one the fan boys were jumping on last year has/is the difference, 12BHP is a massive amount esp with no meth, humble pie needs eating by a fair amount of people imho

Great figures, glad the 20v tuning is getting stronger, but as already said numb nuts will see the results on FB and think every 20v will make the same figures

Bill like i said last friday top work on the Manifold mate

im with you
stock k04 means off the shelf
but an off the shelf unit wouldnt have been ported
its like saying my stock untouched s3 is faster than all the other stock s3's but its had the fueling timing and boost slightly tweeked.
impressive definately
stock k04 its not
