Just thought I would give you guys an update on my Mk4 AUM since my oil pump failed and shot number1 rod through the side of the engine... :grin:
Second hand block fitted from a 80k AUM fully stripped and rebuilt with h-beam steel rods from THS performance, new oil pump, oil pick up pipe and S3 BAM harder big end bearings.
Still running the K04-001 turbo, oem maf, 386cc injectors with THS FMIC and large bore Milltek turbo exhaust, but now with ported exhaust manifold, reduced collector and over sized runner port 3.
Around 100 hours fine tuning and mapping time managed to pull 334lbft 233bhp. Due to having the stronger rods I went all out on the torque mapping, which caused peak bhp losses due to flow and turbo VE, BUT.... the car holds a flat 230bhp from 3300rpm to 5300rpm which makes the average much power MORE than a full spec stage2 LCR running 280bhp. :smug: With launch control the car will pull 0-60 in 4.5sec and 0-100 in 11.5s.
NOW The the fun part.. since we have become a NOS refil station and Wizard of NOS dealer I decided to fit a 200bhp+ wet not kit to the old girl.. :laugh: which means detuning the map to 270lbft to get some peak bhp back and reduce the peak cylinder pressues and pull 3.25 degrees of timing out, it is now closer to 250bhp with the turbo running 95% at the top end.
We fitted the NOS nozzles with the 50shot jets and managed a dyno pull on NOS of 288bhp 308lbft during testing and setting the noz, at this point the idea of getting to 300bhp+ was cut short due the fuel pump hitting its hard limit. Plus the amount of timing pull was was seeing with nos on peak torque was around 10-11cf which I was not happy with, and did not want to pull any more timing back as this would cause higher EGT and lost effichency.
SO new in tank fuel pump pushing 225lph and a custom modded swirl pot fitted, this should see me well over 400bhp.
The next problem was charge cooling and keeping the ignition pull down to 5-6cf the only answer to this was a progressive injection of water &alcohol (methonal) mix direct into the inlet manifold next to the AIT sensor.
Next stage is to finish the mapping, and dial in the ratios for the NOS and 100shot jets with water meth injection, then fingers crossed 330bhp+ 380lbft and a 12s 1/4mile.
I will get some pic up tomorrow

0-60 in 4.5 :shocked:
Keep up the work Nick :evil:

Pretty mental :laugh: wander what it's quarter mile time is !

Nice!! Good to see you in the forum again nick!

Pretty mental :laugh: wander what it's quarter mile time is !
Last summer with just the stock engine, k04-001, FMIC, Forge TIP and Milltek back and around 250bhp 250lbft@3000rpm it ran a 13.8s @103mph on stock rims and goodyear rubber, full interior, full tank of fuel, baby seat and tools. :grin: The car feels twicw as qucik in the midrange now
Its very very nippy all the power on tap between 2900rpm and 5500rpm, but still pull strong to the 8000rpm limiter which when shifting up ther gear at around 7800rpm land the rpm in the sweet spot of the torque band for the next gear. 80mph in 2nd gear, 125mph in 3rd and 152mph in 4th at 8k.
-
Awesome, looking forward to the pics. :cool:
-
would of loved to see u hit nos butten on the rollers :cool:
sounds like ur gona have a right machine on ur hands keep up the good work lads :smiley:
-
Genius at work :grin:
-
right this ir what Im aiming for ko4-001 Is it worth keeping standard maf also the injectors sab reds? so with all the mods without nos and rods can i hit 250-260 with the ko4.001 and is it custom map cheers

Saab reds will be no good for the aum, you will need the inectors from a 225 TT or S3.
With the right mods we will tune your k04-001 to around 265-270lbft 240-245bhp. The main gains over the k03s is how long the 001 can hold the torque for. I wont tuned a customer car to the limit i have tuned mine to.
Nick
-
na i don't want the limit just thought i would ask as someone hit the 260 mark i will Be diffo be doing it And where and what size Are the injectors?

380cc @3bar static.
I have seen claim 270bhp from the k04-001 on its own merits, but I have found the 100% maxed out with the fuel and timing set for power not component protection the 001 will pull 206gs at 257bhp with a dyno correction factor set at DIN 70020. So maybe with some other correction factor it could see over 260bhp?
If your going 001 your aim needs to be on getting the torque curve as long and as smooth as you can to get as much average power as you can. Getting the car to pull strong from 2700rpm then constant to 5500rpm. :cool:
-
Nick how many packets of biscuits to put that set-up on my car? :laugh:
-
yea thats what i mean haha so basically it can be done but toget the torque curve nice i got to loose some bhp?? my goal was 250bhp after that is a bonus lol i just wanted to add 100bhp or slightly more due to agew to the golf and im happy
im still running stage 1 and this being my first turbo car im still loving it but the opower bug is inside me and wanting more lol
also with the mods and how much will be a session with you to be able to get as much out of the car but still being safe cost me cause im interested haha
cheers

I know that you did not reply to this post since 2 months, but i have a question for Nick.
Nick, i got RP k04-001 TURBO, KnN typhoon CAI, Forge 007P DV, Forge Tip, JDM FMIC, 3" downpipe and 2.75" custom Turboback on my MK4 AWD engine code. we don't have a custom remap here in Lebanon, but i have Revo and APR, so what do you recomeend me to do?
and can the tuner fine tune these remap or they are installed as they are???
your reply is highly appreciated.
many thanks in advance,

Best option would be revo stage 2 software, but this will allow the. KO-001 spike to 29/30psi with easy due to the actuator and faster spool rate. You will need to run an inline ball bearing manual boost controller along with the n75 valve. From what I know about 1.8t mapping the ecu will fuel fine ( you will be running stock injectors at 4bar static) you cannot run the 380cc injectors with the revo s2. The revo loaf request map should be enough for 250bhp, but u will need to dial in the timing via lemmiwinks.
When I do maps above stage 1 they are all fully custom and scaled to the exact engine spec.
-
Just an update!!!
The R-tech k04s has been up and running since Saturday pm.. Not had chance to do full data log, but findings are it's holding 2psi more at the top end, boost scale seem much better and more controlled. Then my arse dyno is telling me the car pulls like a b!tch to 7500rpm. Feels like a ko4-023 top end but still got the spooling speed like the ko3s.
-
sounds interesting how much are the ko4s>??
cheers
-

All depends what the are built from, and what machine work is needed, any ko3 ko3s and ko4-001 can be upgraded to a K04s.
Nick
-
im running the ko3s so how much for that to get to ko4s??
also whats the benifits over the normal ko4?? same bhp or more
cheers
-
Good work Nick :cool:
-
So far with out any mapping 267bhp 285lbft :grin: :grin: :grin:
-
see thats the power i want lol so with mapping 300 easy whats the standard internals good for mate??
cheers
-
well seeing as he blew rods out of the original engine, i'd say less than 250
-

Thought rods are rated in torque and there limits are around 300lb???
-
There is no real to know what the rods are rated to, some take 350lbft some fail at 260lbft I have pushed and old agu to 340lbft at 29psi spike and the car is still going strong. I wanted to take my oem road to the limit for testing but number 1 gave way when the oil pump fail at 30mph on the A34.. :laugh:
Nick
-
I will be replacing everything when I do the conversion lil
-
Very tempted Nick.
I want to get a spare AGU and rebuild from the bottom up,whack this new turbo and AUM ecu on it and we'll have some fun :evil:
-
The K04s will be good for 265/285lbft as a retail turbo, and on my car 330lbft 279bhp, but due to it having so much midrange power on tap and can easy provide 300lbft well before 4000rpm I have decided to aim for 300bhp.. :evil: A bit more fabrication work needed and a bigger comp wheel and we should be at 300bhp..... :grin:

so for us its 265bhp and thats safe??

Just doing some more testing, I am testing at 27psi at the moment and maxed out to the red line, the peak power and torque will be down to customer exact engine specs

nothin to do with this post nick but i thought i'd let you know there is a recall for the coilpacks for the ARZ engine :wink:

Update 16th July :grin:
K04S-v2 now fitted to my car and running 21psi flat with a MBC during development... :evil: :evil: Power run here we come..
300bhp or not?
-
ill put a pound on 296..
-
ill put a pound on 296..
290bhp 290lbft 17.5psi to the red line 24psi peak.. :rolleyes:
Its also hit its traction limit on the rollers, we we need to strap it down as if its being live real time mapped, so the car is running just on the front roller against the eddy brake
on the dyno is seeing around 17psi at the red line on the road its holding 20psi..... Its awesome as I have lost non of the spooling..lol
Next step is a dyno on the dyno mapping logging and EGT probe welded in place.... I am off to play
-
I want a ride in this when I come up, PM coming your way too :wink:

Lol wes i went in his aum last time i was down there just had the ko4 001 turbo on lol and boy was it quick lol

Just wased £40 off v-power, the thing is mental pulls stupid
-
thats not waste! thats earnt and fun :laugh: :laugh:
-
You got pm nick lol
-
lol was fun and the launch control was fun to :laugh:
-
Thats 290bhp without running my water injection.
-
Tbh i got a shock how quick it was lol

All this is what sits you head and shoulders above any tuner around,would love to see the generic mappers try mapping this......
-
What system are you looking at using Nick?
I could build a basic system myself, only things I'm finding hard to find is the correct nozzle and a trigger switch...
-
All this is what sits you head and shoulders above any tuner around,would love to see the generic mappers try mapping this......
Its all down to playing around and trail and error testing and crunching data logs... I go bed dreaming about maf flow, egt, boost lambda ect... :laugh:
I cannot wait to get its up and running with all my other mods.. Its going to be utter madness with the NOS, when it pulled 262bhp it made 340bhp on the N0S, so with a bit of jetting 400bhp 400lbft is the aim and to crack low 12s at santa pod before the years out.
I am trying to get all the bigbhp.com project car down pod on the same day.. the quickest we got so far is a 11.4s 134mph from GT35-C20LET.
The the AIM next summer is to blitz the R32 turbos as Gti inter... since one of them stole my faster Mk4 2wd award at the 2011 event.. :cry: Small tuner did well but got fooked over but comes back to KILL 4wd.

Is that the 001 it your turbo on his car mate I want power.lol

Hi Nick, very interesting car you have mate!!!
my K04-001 is an RP turbo so i was thinking to install a Forge actuator with an in-line boost valve set at 25PSI as limit to stop an overboost, what do you think of it???
what did you mean "to dial the Timing? can you explain more mate, you know which chanel and what is the best number?
I appreciate your help.
Best regards,
Sas

Dial in timing using det cans and knock sensors to listen for pinking ( pre detonation of air fuel mixtures)
To dial the timing in we use 7maps, ignition maps x2 related to cam positions, 2x ignition correction maps related to temps, and knock control recovery maps.
The higher the peak boost the greater the peak cylinder pressures, and the mixtures burn quicker and easier, so with 25psi peak boost less timing is needed to get a the combustion to force the piston down at just after TDC, if too much timing and the combustion can happen as the piston comes up, which give know and power loss, too little ignition advance and again loss of power and high egts. As the peak cylinder pressure drop along with the boost at the higher rpms we can add timing to compensate for a slower flame front (start of combustion). There is a find balance to getting if right to make the best power stroke, a poor timing map can lose around 25bhp on a turbo engine. On peak boost I am seeing a safe 12deg and at the top end 22deg, with water injection I can see another 4deg on top and still be knock free and gain 10bhp in places.
Correct ignition timing is free
-
Bloody iPhone
Should say
Free power for same amount of fuel and boost.

Before I reply, I want to thank you a lot Nick for your help you are showing, especially that you are not obliged to do so. I REALLY APPRECIATE IT!!! :smiley:
Dial in timing using det cans and knock sensors to listen for pinking ( pre detonation of air fuel mixtures)
what is a "det cans" and where I can find the "knock sensor" - is there any links i can follow?
To dial the timing in we use 7maps, ignition maps x2 related to cam positions, 2x ignition correction maps related to temps, and knock control recovery maps.
can this be done when I with Lemmiwinks? or SPS3? if not what should I do especially that I am going with Revo stg2
The higher the peak boost the greater the peak cylinder pressures, and the mixtures burn quicker and easier, so with 25psi peak boost less timing is needed to get a the combustion to force the piston down at just after TDC
how I get less timing with Revo? and what is a TDC? I heard that Revo got the SPS3 that can adjust boost and Timing, would this help?
As the peak cylinder pressure drop along with the boost at the higher rpms we can add timing to compensate for a slower flame front (start of combustion).
Can you explain how I can add timing at higher RPMs??? What did you mean by “add timing to compensate for a slower flame front†????
Can you explain me more about the Degree??? And it is used for what and how do I should adjust it???
Many thanks in advance for your support and Help,

Thanks for the reply mate :smiley:, I will surely google it.
My 001 setup is doing well for a none mapped car, now i have a lot of mods done, all is needed is the remap. I got an ECS stg 1 Clutch KIT, all the bushes in Poly, Metal link for the sway bar, Forge TIP, DV007p, FMIC, N249 bypassed, Oil catch can, new coil pack, NGK sparks BKR7E, ECS N75 Race, I am relocating the DV this week-end, and I bought a Overboost kit like you advised and i will install it when i do the remap. I just want to know if would you advise me to get a FORGE actuator? and with which spring? :undecided:

Hi Nick,
It is been a long time we did not get any updates of your car.
Anyways i wanna ask you 2 questions please:
1- Can I send you My ECU so you do me your customs remap for the K04-001? I know that you prefer to have the car to put it on a RR session but I am on a dead end road now, and when I get back the ECU i will do a fine tuning on a RR session here, can this be done?
2- Do you prefer if I get a Forge Actuator for my Turbo? and which spring should I get?
thank you in advance mate,

If its a k03s then forge actuator and blue spring would be recommended
