420bhp hybrid k04

[IbizaAlex]

Going by the MAF figures, its not much higher than a stage 1 car. I logged an S3 with stage 1 Revo and that made a peak g/s of 251 and that was a DSG car that only rev'd to 6640!

That timing pull is and shouldnt be that high, ever!

I dont see why you also need RS4 injectors and an extra intake fuel pump. There are plenty of people running S3 injectors on 3071's with no issues.

I have my hybrid K04 back now, but I need to fit some rods first then we will find out if its worth doing or not. If it makes 10 bhp more than a normal stage 2+ car then dont waste your money. If it makes 20bhp more running less boost then its worth it.

Fuelling itself was never an issue with regard to volumes. Sufficient fuel got to where it was needed.

I think with a Hybrid though, you would probably need an uprated electric fuel pump to send fuel from the tank to the engine at a higher rate though.

is a mainstream K04 upgrade package likely to become available any time soon from a large and reputable tuning firm? also does this stage 2.5 on revo software have specific mapping or is just tinkering with the SPS module?

Revo aren't entertaining K04 Hybrid's at this point.

I think it's solely Statllers who are a GIAC dealer have had the turbo tweaked, then got a file from GIAC to utilise it's benefit's.

Correct about revo. Its not been fully tried with the stage 2+ file with the hybrid that im using so im the test pilot.

Is that the GIAC map thats got the crazy timing pull then? Needs some work then.

Until Revo bring out a fully tested map with a hybrid K04, this won't be an option for me. To much risk and massive PITA to completely return to stock if the engine fails.

The GIAC files have always been fuel rich in my experience. Having just seen the log you posted Al it don't suprise me that they had to run it so hard to get the figures. I have seen timing pull in the 14 and 15's on others. On another point the seals on the HPFP are listed as a seat part so can be replaced regularly just like the cam follower. I Cant see why a hybrid K04 would ever be a viable option considering the costs involved. If you want a bit more power for 1/4 mile action just put a 50 shot of NOS on

The log above was from a very well specced Leon Cupra TFSi with GIAC Extreme Plus, S3 Core, No A/C, Forge Twintercooler, Decat TBE, VF Intake, RS4 Valve etc etc fully sorted car with LSD, Uprated ARB's, Coilies, WOT Box etc etc etc, and it ran the 1/4 mile in 12.9 @ 112.

I was not aware that you could buy the seals for the OEM fuel pump on their own Ryan, but it is handy to know. Working on the Pump is not something I could be hooped with though being honest. Removing it to inspect/change the camshaft follower is bad enough

Regarding the MAF figures above, it would appear that they are not really hugely linear on the TFSi engine, and things like intake diameter can affect this. For example Evoms tend to show the highest figures and Twintakes show lower figures, but on the r/r, there is probably nothing to separate two cars (one with Evoms, one with Forge).

I would be really interested to see how the Hybrid K04's go, but I won't be the one leading the pack doing it.

Personally, I think there are going to be a lot of threads on here in the next year or so as more of these cars go out of warranty with fairly severe engine issues and they will probably be working OEM Turbo Chargers. I may well be wrong (certainly hope so) but I fear that as the cars get older and less money is spent maintaining them (always tends to happen with older cars), I won't be.

I don't see the point in nos shots, I'd want that extra power 24/7 and not through artificial means.


I too agree that once these 2.0tfsi get older they are gonna be needing alot more tlc than people have anticipated. Just look at the old Mitsubishi carisma with the direct injection engines for example.

Saying that though the fatplaster has done over 70k on his Cupra, is running jabba stage 2 plus and has had no problems whatsoever. It's not quite as fast the two revo cars but it's not really noticeable

 

[Blade]

I do agree that correct maintenance is the key when running highly modded cars. I treat every 5k as a major service interval and touch wood its been fault free up to date. Personally i think the K04 engine is very well built, its the owners that need educating on how to look after them properly.

I have seen timing pull in the 14 and 15's on others.

Only goes up to -12 Ryan?

 

[Blade]

well iv,e seen logs with more Dan, but i wasn,t there when they were done. It was in the USA, so i can,t confirm their validity.

 

[jon-tfsi]

Have seen timing pull of -5.8 on the Revo trial software set to B6 T6 F9 with no other mods other than the Cats removed from the standard downpipe

The car felt REALLY strong for a stage1

here is the thread with the released power of the hybrid k04. http://www.mk5golfgti.co.uk/forum/index.php/topic,19944.0.html

ignoring Hp figures, Hurdy's ed30 which was pretty highly strung and DSG in his own opinion was noticably slower than the K04 hybrid.

I also believe steve@stadtlers was making 12.7sec 1/4 mile runs with full interior as well

It wasnt even running correctly then either. I think if you can get a hybrid done for £1.5-2k then its deffinatley worth it and i believe the 50hp+ claims over stage 2+.

 

[wild willy]

The old K04 -023 pulls 70 bhp more in hybrid form than in its stock stage 2 form. Thats going from a 26lb/min compressor wheel to a 35lb/min compressor wheel (actually the very same wheel you guys run in your current K04's).
The secret to your K04 gains will be in getting the info off the suppliers as to the new spec of the hybrid wheel. 44lbs/min would seam doable and so power could be up to 440bhp.

£2k for a hybrid seems like quite a lot of outlay for a turbo solution that will, if your lucky, get just about 400bhp... really wouldn't you be better with a bigger turbo running less boost?

Jabba can do it for 1.5k.

It's all about the spool and response IMO, which slot of the BT kits don't do very well.

It's the way the oem turbo is integrated into the manifold which gives it such awesome low down response.

IMO a 400hp ko4 will whip the ass off a 480bhp big turbo 2.0tfsi

Will it not be a bit highly strung though? Just thinking from long term reliability perspective... I quite like the idea of k04 over a big turbo, just worried that its gonna put unecessary strain on the turbo internals when a BT solution would be running much more in a comfortable operating range... what do you think?

Well in regards to turbo reliability it should in theory be the same as a stage 2 plus car as the turbo being uprated will also means it's stronger and more durable according to the likes of T.D

HAHAHAHA i get that on my stock Cupra and SEAT say that timing pull is acceptable LMFAO!
