Hi Guys,

Has anyone heard anything about the am-04 turbo? I thought there was a tread on here about a month or two back but I can't find anything now.

It's a k04 hybrid(tt&s3 not k04-001) which will bolt onto k03s cars I don't recall seeing any power figures though.

Was looking at this a while back, looks a great piece of kit. Would be a great upgrade for someone wanting no more than 270bhp. Of course the problem is on the 150/180bhp engines the injectors are maxed out well before this, even on 4 bar.

[rob_watti]

i would also be interested in this, is it possible to fit the k04 to the auq engine??

 

[Badger5]

not seen or heard any figures from it as yet

SCN has more info on it.

Yeah, they have intended the turbo as a direct bolt on the standard mannifold, all you'll then need to do is get a customised map from the likes of Jabbasport or AmD.

Oh no wonder I couldn't find anything on here![)]

I should be getting my anni back of the other half soon (she wants a BMW) so I would like to stick somthing bigger on there.

According to Jabba the ihi entry level only makes 280 on the later engies. So 270 ish for this sounded great

Did'nt they also say it would need a manifold they've found?[?]

 

[MkIV Turbo]

You could be right bill, I thought their manifold was only needed if you were wanting better top end flow though.

I thought the same that the manifold they found had better flow, not essential. I'm no expert though[:I]

Hasn't the anni got big injectors on a 3 bar fpr?

I know the AGU is small injectors, mine has a 4 bar fpr now, if I need new injectors for it then for 30 bhp it's just not going to be worth it, I may just have to bite the bullet and either change to an S3 or big turbo the anni.

[rd20vturbo]

Standard 180 injectors are NOT maxed out at 270BHP, with a 4-bar FPR they are good for 300BHP - I've done a 293BHP dyno run with stock injectors and 4-bar FPR and injectors were 98% duty cycle. My engine regularly makes 275-278BHP on the dyno with stock 180 injectors and a 4-bar FPR (goes into the 290's with nitrous spray on the intercooler) and they are never maxed out.

 

[MkIV Turbo]

98% duty cycle is too high to be reliable in the long term though and will eventually lead to failure. The injectors will hardly even be having enough time to switch off at 6400RPM before being asked to switch back on again. Anyone who knows anything about solenoids will tell you that's not ideal...they get hot...and stick. 6400 RPM + hot turbo engine + no fuel = bang. Big time. Also running the injectors that close to their limits can create problems for getting the fuel to atomise correctly. Also, I've never seen another 180 engine running the amount of power you have on stock injectors.

yeah course you have []

Im not doubting your claims, but i am doubting the RR these figures are achieved on. and i fail to see how freezing the core gives another 10-15 bhp?

I may be wrong here and i will happily apologise if i am, but i would like to see those figures reproduced somewhere else? Cos imho the stock injectors wont push past 260's..... Didnt John Wilko uprate his with the E05 to produce about 270 ish?

Not wanting to alienate you are slate you, but it does seem a little unfair to those members that may be take this in and believe that 300 ish bhp is possible on a ko4-001... which plainly put ISN'T.

 

[rd20vturbo]

But I don't have a K04-001, so your assumption is incorrect, we're not talking about the 001 here, the AM04 is a hybrid K04 and so is mine! And yes, using the nitrous halo spray on an intercooler generally results around the 10-15BHP power increase, seen many results across the net on various makes of cars. Don't be so quick to make judgements about things when you don't have all the facts please.

I've had this setup for around a year now and always made over 270BHP on the dyno, never had any problems - I'm not interested in who believes what, just reporting facts here. Plenty of people have watched my car on the dyno make these numbers.

I've seen and heard of other hybrid K04 VAG cars make the 270-290 range, so can't be a fluke. remapped LCR/S3/TT 1.8T engines usually make 265+BHP with their K04 turbos, so why so hard to believe a hybrid of similar spec? I'll be upgrading to a big turbo this year for 300+! [^]

 

[rd20vturbo]

I'm not here to argue or be told I'm lying because I'm not. The AM04 should be a very good turbo, but to get 270+ you'll also need other stuff like a different downpipe, FMIC, intake, etc. but my standard 317cc injectors are doing just fine. If you have the smaller 210 or 282cc injectors they would definately need changed. I'll be switching to 386 or 440cc injectors when I go big turbo later this year.

Food for thought ... the 600BHP HPA R32 uses twin hybrid K04 turbos and standard R32 injectors - who would have thought stock injectors could support 600BHP - but they do - do the math, I'm happy!

 

[Tim Sims]

Sorry Rob i didnt realise YOU had the AM04 already fitted... am i correct in thinking you were ko4-001 tho?

Infact i wasnt even aware that they had actually sold them on? Like i said i wasn't calling you a liar, i was doubting the figures...But i think its a road we dont need to go down then. If you're happy then good on ya.

No offense meant mate! []

 

[Badger5]

dont think Rob has an AM04 he's got a K04 hybrid.

 

[Shock_xe]

Cant Believe I missed this [:O] To clarify thigns, Rob Dopn doesnt have our Turbo, from what I understand he started off with a K04-01 and then star performance modified it to their spec (they not sharing secrets)

The AM04 is 80% K04-22/23 which is used in the LCR/TT225/S3. However it Does bolt on to a stock K03 Mannifold/DP/Charge Pipe, I have used a different variant of the K03 mannifold as there are a few variants, some with better flow rates but this was a personal thing not a nessecity.

I also have a sports actuator on mine which again is an option. The only things you need to change is a new oil Feed line (Supplied) and a new TIP (Turbo inlet pipe) due to the increased diameter of inlet. We are supplying one which is made out of Cast ALU 2" which then goes to 3"

I am also using an 3-5Bar adjustable Reg, S3 Pump, S4 maf 3.2"OD, 3"ID 440cc Green top Injectors at 3bar, 3bar Map sensor, 17core FMIC, 3" Turbo back System with 100cell cat, Our stage 3 hybrid 228ml clutch (400lbs WTQ rated) Large port ADR Head & exhaust Cam, and being fabricated at present our own Custom intake Alu mannifold, Oil Catch Tank and Oil Cooler and water injection

All of the above we can supply. The turbo is on the car and running using a LCR/S3 TIP at present until all the bits are fabricated. Turbo has covered around 2000miles so far using lots of different ECU's [:I] So far its had Revo, Jabba, Stock and Cupra R. All running with no issues. Im dying to get it mapped up as the majority of the bits are here and waiting, just the clutch/head to be fitted for the most part.

The reason why its taking so long is that I want to have the car finished 100% before its mapped and get the best I can out of it. Although we have 2 AM04's ready made and are hopefully going on 2 cars very soon (1 being Audi.... Bill u can prolly guess that 1) and the other is undecided... Maybe a golf []

For those who havent seen pics, Here.

EDIT:

Damnit I cant get the Img Link to work, So unless someone can tell me will have to see http://www.seatcupra.net/forums/showthread.php?t=46664

The Jump it K03S to AM04 is a similar =Jump from K03-K03s as a Jump from K03s- am04 is 4ml bigger compressor housing, 4ml bigger inlet, larger main vein and a bigger exhaust wheel, This is a similar jump from K03-k03s. So the gains are double K03-AM04

 

[rd20vturbo]

Thanks m8, yes Star have K04 turbos re-worked to their own spec, from what I know they sound very much like your AM04 turbo, they certainly work well, most of these hybrid K04's in conjunction with other mentioned mods usually see around the 270BHP mark, not just my car, I think Star have done about 5 and all make good numbers.
