K04 Max Power

[Lestat]

Hello.

First at all excuse my poor English.

I have a Leon Fr FSI with the K04 in it, ATP Downpipe, Autotech HPFP, Neuspeed CAI, EuroJet TP.

Also have Labonte Stage 3 Meth Kit (the screen broken and is not working rigth now).

The DV is ventilated because the CAI haven't the falange for the S3 DV.

I feel my car very fast but I don't think have more than 300 Hp, and I read than this turbo are 350+WHp capables.

What more I need for more power? In my plan is weldded a falange to the CAI, put the Meth kit working, catback, Forge actuator and RS4 return fuel valve for 136 bar.

Also have IE rod ready for install.

Think 350whp would be pushing it. 360hp at flywheel is the average. Some people have managed up to 380hp at the flywheel.

think you will be able to hit 400 no problem mate if you get it hybridized

Hmm why not go for a 3071R instead you defin get more power this way or even billet turbos.

because you wioll suffer alot more lag on the big turbos than you will on the hybridized k04

What is hybridized k04?

What is hybridized k04?

Rather than going for an expensive replacement turbo for the K04, such as the Garret one mentioned above you can have your exisiting K04 turbo modified.

This is relatively new for the K04 but some companies now offering this modification.

Secondly just out of curiousity you say have an 'FR'. As standard the FR ran the K03 turbo so assuming you already upgraded to K04? If you do still have the K03 then 300 bhp is probably about right as you looking at 40bhp difference as standard k03 v k04.

Might also be worth adding an intercooler such as one from THS or APR to keep things nice and cool and possible looking at a better induction kit that your CAI.

What remap are you running, revo, custom code, GIAC etc? You mention a stage 3 meth-map ?

Should have WMI on by Saturday, utilising max Revo Settings of 9 Boost, 9 Timing and fuelling of 5 or 6. No idea what the power will be, but if all the hype is true, hopefully should see somewhere closer to 400bhp from 370bhp the car has without the WMI.

the lag won't be THAT big but then again I go on other forums talking about turbos I like the idea of port/polish turbos too but for me (personal preference) would like bigger turbo instead

have a look at these, this was hurdys plotted against DANGBS GT2871 with WMI. now a GT30 would suffer this even worse.

Notice at the huge difference upuntil 4250Rpm the k04 is way ahad on power, and only then does the GT28 take over. nearly 100Hp 100Ibft more at 3.5k. that make for a much quicker car around roads id bet

Stop using that graph sy! My car was broken then!

I dont know mate, whilst dans car does take longer to spool up, when driving with anger its always gonna be in the optimum rev range, and if someones going BT over k04, it would be worthwhile to upgrade the valves springs etc etc to let the motor rev up to 8,500rpm, a turbo that will sustain its power to 8.500rpm will be a beast.

TBH Id rather have dans setup over the k04, its quicker when driving hard, and when not driving hard he gets much better MPG, win win as far as im concerned.

Thank you I should said this from the begining! in BT for the win esp when it can rev @8.5k

turbo has nothing to do with how high the car will rev!, fact is if the turbo is pulling all the way to that revs it means all you internals are being harder pushed that with the KO4 and the fact the the K04 is half the price, also has less lag and it is still a K04 so doesnt need to be amended on car insurance

I'd say 420bhp. My LCR k04 turbo in hybrid form flows 30 bhp over a stock k04 albeit the mk1 lcr. The mk2 twin scroll is a superior turbo and i would expect at least 35 bhp over a stock one couple that with 20 bhp from wmi and your into super car accelleration performace. My 300 bhp lcr is very quick so 420 must be insane.
Big turbo would have to be past 500 bhp to make it worth while surely. What head room do you guys have in your injector duty cycle to allow these mods to take place.
Remember also that the hybrid will give you a flatter torque line in the upper revs also so its not a proportional increase in power.

yes but a k04 turbo coupled to a motor built to rev to 8500rpm is pointless as the K04 cannot sustain boost at the higher rpm scales.

You guys should hear how much dans insurance is with all mods declared through a specialist, its fooking cheap as chips, roughly a third of what im paying IIRC.

out of interest which companies in the UK do the hybid K04 upgrades. I know I am a bit out of date but last thread I read suggested they had only done the K03 so far?

Also do they usually 'uprate' your own turbo or is it a swap out as part of the deal?

 

[Al]

Turbo Technics is one.

Statller have just fitted their DSG Edition 30 with a Hybrid K04 (and some other goodies) and from what i've been told (and I quote) "It's a F***ING missile!!!"
Looking forward to seeing it run at Brunters (Inters)

 

[Al]

It was a missile before though .

I would be keen to see how much faster it would be vs the same car with a stock K04 turbo Realistically though, without trying to sound negative about it, even if it was say 20bhp more, how much that would equate to on the road when you are near enough at 400bhp anyway?
