Been chatting to my local tuner and seeing as I have the Milltek already and Stage 2 is now available, thought it'd be rude not to give it a try.. :wink: So basically setting up a date with him tomorrow (hopefully sat morning) and I shall be giving it a whirl.
Only concern is that i've heard that you lose some midrange punch in exchange for the increase in power high up in the revs.. :rolleyes:, so i'll be giving it a try for a week or so and see what it's like. If I fell i'm not gaining enough oooomph to compensate for my midrange loss, then I will revert back. But for £50 may as well give it a bash... :wink:
Will report back my findings when done..
-
do you not need an intercooler? :smiley:
-
Intercooler isn't essential, but you will get more heat soak with the higher power output and so it is a good investment to look after the engine lifespan (also gives a few more horsies!!)
-
As I have mentioned previously, the limiting factor is fuel delivery. The mid range you have just now is not all that it could be due to the fuel pumps inability to deliver the required amount of fuel, and the ECU pulling back boost to compensate and therefore stopping the engine from running lean. The same thing will apply in stage two, only with the top end being restricted.
In reality, midrange is not affected that much, but the top end is a lot more enjoyable and the top end being more lively makes the mid range seem more paltry.
It will be interesting to see what you think, but you really should put in an uprated panel filter as the OEM filter is pap/inefficient.
-
Which panel filter is best for dtock airbox?
-
I have just put the ITG Pro Filter in mine, not the cheapest but seams to be good quality.
-
Where is that from mate?
Is it for stock airbox?
-
Yep it fits the stock airbox.

Blimey you didn't hang about :laugh:

LOL its my first mod :grin:. Did it come with fitting instructions?

ben......do you not think your cars fast enough??? :huh: didnt it come secont at inters for a mk5? and the only one that beat it was the regal one with ALOT more mods??

do you not think your cars fast enough???
i didn't know you had a sex change while we were offline :grin:

i didn't know you had a sex change while we were offline :grin:
i didnt...i dont think :tongue: but seriously, hurdy tried for more power and ended up loosing power, bens car is faster down the quarter mile than awesomes APR converted 380bhp GTI. with more power, theres more chance of things to go wrong :undecided:
+youd probs be in real need of a lsd
-
driver skill had alot to do with vtec's fast sprint time. 300bhp really is the limit for a front wheel drive car before needing some serious mods and almost throwing money into the wind.

the DS in DSG doesn't stand for Driver Skill :grin:

lmfao :grin: :grin: :grin: :laugh:

you can never have too much power :grin: it can only go bang :laugh: i am going for stage 2 soon :evil: but mines a manual
-
I've been there, fuel pump included and traction does become an issue :laugh:, it struggles in 3rd in the dry to grip.
-
Power is useless without control!
It's all about driveability and not big bhp, imo.

word :smiley: :tongue:

I've had mine dialed back to just over 300bhp and similar torque and I'm not suffering from the dreaded clutch slip at the moment, so all is good.
If anything it is faster from the off, but a lot slower at silly speeds. More useable though.
I phoned JBS at the beginning of the week and they are struggling to source a clutchpack :sad: and without it I'm stranded at 300 bhp :cry:
How does this link in?
Well, DSG is touted as being stronger than most people thought and I would generally agree, it is just that you have to be prepared to spend your way out if things do start needing upgrades....and that can be relatively expensive for most people to stomach.
When it is all sorted though, 340+bhp, LSD and DSG may just see some good times at the pod :evil:

Nope, but try this http://forums.vwvortex.com/zerothread?id=2547554

Changing the panel filter on the engine cover is easy enough, but it is a lot more fiddly than most other cars. The cover is held on with 4 stays and you have to release the connection to the MAF and piping down the left side of the cover as you look at it. Also, the connection to the air feed needs to be removed.
Once off, you have to remove about 8-10 screws then open it up and then change the filter and obviously re-assemble.
On the old 1.8T it took a couple of minutes. You need about 10-15 for the assembly on the TFSi

Guys guys guys... I 'm not going daft, don't worry. :grin:
The stage 2 (from what I can gather) will only be giving me a few more horses and is really just being done so it can tie in with my Milltek properly seeing as I have it. Plus it's only £50, so thought I may as well.
I'm certainly not going any further than that for most of the reasons that have been mentioned. So no fuel pump etc (for many reasons) as I am quite happy with what i've got.
Just though for £50, it seems I may as well..
-
One thing I do know though. If i'm not happy with it in anyway, it'll be going back to exactky how it was.. :wink:
-
Hello pal, I'm suprised you can go stage 2 without a fuel pump, I'd have thought you would need it to supply the extra fuel pressure needed to go with extra boost, ignition etc.
-

Nah thats not the case. The car does need an uprated fuel pump to take full advantage of the code but it works ok with the stock pump too. The ECU does compensate for lack of fuel by dropping boost to stop the car running lean. However you DO need an intake upgrade for stage 2.
Ben - Please tell me you are going to put in an uprated panel filter :smiley:
Edit: There will be stage 2 + for those of us fortunate enough to have uprated intakes, full uprated high flow turbo back exhausts, uprated intercoolers and the uprated fuel pumps. It has not yet been developed on a UK car though.
-
TBH can't really see the point of doin it then if your not going to make the most of it, but I also understand that Ben's in an unusual position that his ED30 is a company car so things are a bit different :smiley:
-
....My understanding is that if it's a Revo, you need their Stage2+ with an aftermarket fuel pump.
-

Well as it happens on a standard K04 TFSi the terminal speed on the 1/4 mile is approx 100-101. On a revo map with a full exhaust and uprated intake, approx 107.
With an intercooler and fuel pump upgrade, losing the rear seats, junk from boot etc, closer to 110 should be possible. Stage 2 asks for 1.4 bar of boost at the top end of the rev range, but the fuel pump only allows 1.1 bar. The missing 0.3 bar would make the car a monster at the top end and should not be subject to wheelspin on stage 2 code.
Stage 2+ code will be based on a car with all the mods listed including the pump as RR mentioned.
-
Jeez, I havent even had time to try the hammer with mods going on and already there's an update out.

You have all the mods Keith, but they are not doing any good gathering dust in the garage :laugh:
I am still keeping my eyes open for an exhaust for your car bud. Will be def be passing through Edinburgh tomorrow by the way.
-
If its in the evening pop by.
Aye once regal deliver the fuel pump next week its going into Star for the day and getting everything added.
-
From what Kev from Revo said.. (and on there literature)
Stage 1 = ECU remap (no other mods)
Stage 2 = Full Turbo back exhaust, sports cat down pipe, Intake, Ecu Remap
Stage 2+ = Full Turbo back exhaust, sports cat down pipe, Intake, FMIC, Uprated Fuel Pump, Ecu Remap...
I will not be going for the Stage 2+, just the stage 2.
And Al, I will get a panel filter just for you mate... :wink: :grin:. Which one do you recommmend?
Oh another thing mate. You mentioned that the fuel pump only allows it to run at 1.1 bar. But when my car was on VAGCOM, it was requesting 1.5 BAR and getting exactly that... :huh: I will get Neg (lad with the VAGCOM) to confirm..
-
I see Revo have different stages, not to sure about requested figures and actual, so i can't really comment on that. Will be interesting to see what you think Ben.

Hmmm. Would need to see the logs. Perhaps you had a lucky run when yours was logged as the pump does not always return the pressure requested from by the ecu.
As for panel filter, my choice would be for something like a green or K&N. I have a pipercross foam jobby on myself just now until I get a decent intake, but its only because I got it cheap.
With regard to fuel pumps, the guys who have them fitted already report that the gains are where commanded boost is highest. On stage 1 Revo this would be midrange and on stage 2, top end.
-
I had fuel pump and stg2 APR and it was deffo midrange where it made the biggest difference, +50ft/lbs just where you want it, 3500rpm
-
....May I recommend the ITG Competition panel filter? - One big fat mother of a mattress which fills the box very tightly and is well proven technology.
-
I jus bought the itg filter ben. It arrives tomorrow, i know there wont be a noticeable difference but should hopefully let the engine breathe a litttle better.
Cost £58 deliverd nxt day before 1pm
-
Another VAGCOM reading to look at is the rail pressure. Under APR mine was almost 47% below standard pressure at one point :shocked: this meant the engine was running extremely lean. The fuel pump is the one sure thing to prevent the engine running too lean with big power IMO (and in JBS's too!)
-
Still strange the APR saga on your car Hurdy, I'd love to know the reason
