Hi, I have an ed30 dsg and will be going to R-Tech when i'm ready for an engine/dsg map.
I have the following hardware and i'm wondering what your thoughts are on the output i'm likely to achieve. I'm not looking for big numbers and i'm even going to leave the stock air filter system in place. I use 99ron fuel.
- BCS de-cat downpipe mated to standard system
-S3 intercooler
-APR hpfp
Thank you...
-
Your cat-back will be the limiting thing... You'll struggle to get over 330.
Sort that out and youd get another 20-30bhp
-
Thank you Rich, when I saw your reply my belly went over with excitement lol. I didn't think i'd get anywhere near that figure, i'd be well chuffed with that. Would i benefit from fitting the rs4 valve that i see mentioned on this forum? (As it's only a few quid!).
Thanks for your help...
-
Not really. Best thing to do is get a 3" cat back on there before hand.
Ohh... have you got an intake on? Youll need one of those too to get the figures above.
-
Ok will leave the rs4 valve out. No i haven't got an intake and i don't plan to get one, don't want any of the increased sucking noise associated with them and will be happy to go the quiet route even at the expense of some bhp.
So, bearing in mind my hardware, and the fact i'll not be fitting an intake or a cat-back...what do you think R-Tech can do for me?
Thank you...
-
I have never heard of a catback yelding 20-30hp the best it can give you is a better sound ,the ko4 is a small turbo so getting 20 to 30 hp from a catback upgrade isnt right 5hp seems more thinkable you will reach 330-335hp my friend with our without catback
-
The OEM cat back will limit power. As will having no intake.
-
You'll benefit for the RS4 FPRV as you already have the HPFP fitted and a better than OEM IC, no brainer for £40 plus fitting.
Is a bit restrictive with the OEM cat back on. Yes a HPFP and better than OEM IC will benefit even a standard car but your nearly there so why not get a decent (BCS) 3" cat back?
Niki will only say "it's all about the flow" which yours is not at the mo. I think around 320 ish but Niki will get the max out for you no problem.
-
Not attacking you brother but it wont unless hes running a GT30 turbo then i would say go with a catback for better flowing but a ko4 is small enough to make a 2.5" catback limits his power potential
-
Not trying to hijack but is there any ko4 car running anywhere between 370-380bhp without wmi?
-

Speak to niki if you don't believe me. My mate had a stage 2+ edition 30 mapped at rtech with Oem catback and it didn't make what it should have done due to it.
-

Think best I've seen on a ko4 is around 350-360bhp

+2
Flow is very restrictive on the oem Catback,u should see the difference in size of the pipes oem vs bcs"big difference"
As niki says"it's all about the flow"

Thank you for your replies fellas, all very interesting. Just to clarify, i'll not be using an intake or an uprated cat-back, just the hardware mentioned above - it would be great to get a nice figure at R-Tech (using the rs4 valve) then post the result here to show that expensive intakes and expensive cat-backs are really not worth it, so saving a few bucks.
Jeez, i'll be chuffed with 300bhp lol, even the standard ed30 is fun at 22-something bhp
Thanks all...!

Nikki can put in a piper cross filter into your standard one with stage one map and that'll be 300 :driver: which is nice

Hmmm!

Yeap, mine is 362bhp without WMI and that was all well within limits with a nice safe progressive map.

If Niki doesn't make 300+ from your car I'll drink my wife's p*ss!! mmm

MC71's is running 370bhp ish.
My mates Stage 2+ edition30 is running 365bhp with an R-Tech map.
Look at James build thread for a list of the best flowing hardware.
Best flow = best power.
The limiting factor is the hardware, not the mapping :happy2:
(Niki mapped the 700+BHP dubshack racing mk4)
-
Thank you all for the replies.
Since fitting the de-cat downpipe, pump and intercooler I have become increasingly curious as to what is achievable without an uprated intake and catback so going to try this route.
One more thing....i'm guessing the CEL can be removed when mapping, is that right?
Thanks...
-
^^ correct... niki will do that.
-
That's great, cheers fella...
-
I cant help but think you are limiting yourself with the hardware.... @R-tech-Nick (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=2179) will be the best person to tell you.
-
I have no idea whos niki but im sure niki will not tell you a catback will give you20 to 30 hp neither an intake will im not from europe so thats why i asked how much power are ko4 doing in your country and a friend of mine runs a ko4 an have 370bhp without a catback neither methanol and with an R intercooler on his GTI

Niki is the owners and developer of R-tech maps.
I dont know why you wont listen to what I am saying.
My mate had his ed30 mapped at r-tech.... twintake. fuel pump. decat. OEM catback. S3 intercooler. it made 332bhp.
Reason why it only made 332??? OEM catback.
It should have made ~350
-
I made 5 hp more after fitting s3 cooler and hpfp over stage 1. Reason? Stock catback.

Twintake may have held it back too. They aren't great on K04 cars as we all know
-
Thanks for all replies, some good points being made here.
Cheers...
-
So a FBO ko4 GTI should make a strong 350-360bhp on Rtech tune thats good numbers good luck guys

Cheers Adrenaline...

I always say that and the reason I sold my Twintake after having it on my car for only 2 months but (and by no means any kind of proof whatsoever :laugh:)..........
Mine at stage 2 with the awesome ceramic cam coated free flowing REVO CIA and BCS Powervalve TBE with 200 Cell cat made 331bhp (R-Tech tuned) and IIRC SaintSteve's stage 2 map (also R-Tech tuned) also made 331bhp but with a Milly TBE and the Twintake, go figure. :confused:
-
MC71, have you at any time thought the revo intake too noisy?
How would you describe the noise when you are giving it some?
Cheers...
-
^^^^ You'd certainly not hear the REVO's whooooosh dissssssssh in my car on WOT due to the noise from my Powervlave TBE. :laugh:
Anywho......when not ragging the car the REVO CAI is relatively quiet while pottering around town, yes you'll hear it but (personally) I don't find it intrusive.
:smiley:
-
...lol, ok thanks for that, so if you had a standard cat-back, that revo is going to be loud(ish) by the sound of it.
Cheers...
-
I've got the same revo intake and it's fine, even on the motorway at higher speeds it's fine, I've got used to the sucking etc! At first I found it loud but just knowing that it's more free flowing and is going to help with the gains when I get the car mapped is all good :party: :evilgrin:
-

Whats your location? Im sure someone might be localish that could demo an intake.
-
Hi and thank you for everyone's input, much appreciated.
I realise i'll be losing out on some bhp by not fitting an intake but I really don't want any sucking noise in the engine bay so i'm ok with that.
Regarding the rs4 fuel valve, if i fit one, will the car run fine bearing in mind i'm not mapped yet? I'm going to get booked in at R-Tech when I know what time i have off from work.
Thanks....
-

You should have no issues with it installed on an unmapped car.
-
Ok thanks very much...
-
How come you went down the route of hpfp + fmic but not I take as I'd say that's going to be a very lkmiting factor compared to the rest of ur mods ?
-
Hi DeanSutherland,
well in answer to your question, when I bought the ed30 I had read about the injectors flowing more fuel than the normal (but still amazing) gti so I treated it to a pump.
I had also previously read an interesting article about the ed30 motor by a tuning company called mtm who mentioned the importance of uprated intercooling, so I treated it to the s3 cooler.
I have also fitted a BCS decat downpipe (my favourite uprated item) and prior to the remap will be fitting the rs4 valve and uprated panel filter.
I love how the car sounds right now and as i'm in my thirties I do not require any extra noise from a cat-back or any sucking noise from an induction kit. I'm well aware that I may be short of a few bhp by going this route but i'm fine with that.
Ps, just saw your wheel colour in a pescara thread...very nice.
Thanks.
-
Mine with ITG maxogen intake & milly cat back made 302hp & 325lbft, limiting factor, exhaust then HPFP.
Thing Niki's wife Ed30 has made good figures, but i know from the updates he has changed quite alot now.
-
Hi Frodo-anni,
Thanks for your input. I guess you and I have gone about things in a different way. Funnily, if you put my downpipe, pump and cooler on yours, it would fly.....and I guess if I mapped mine with your intake and cat-back, mine would fly :-) Although saying that, yours at 302bhp must feel rapid now. Are you going to add the extra hardware then tweak the software?
The next thing i'll be doing in readiness for the map is getting a new oil pick-up pipe fitted. If it wasn't for this forum and all the helpful info available, I would never have known about this important maintenance tip, fair play.
Thanks.
-
I have every possible mod on my eddy apart from wmi and I have a twintake but it's a hybrid with itg filters as it's the forge filters that don't flow well and niki got 360 and 390 from mine extremely happy.
-
ah ok mate can understand i think for the sake of abit of noise at high rpm id have an intake :P

You wont get any benefit from the RS4 fuel valve if you have an edition 30,you already have S3 injectors in your car all you need is an hpfp for fueling and your good to go

The valve helps maintain the required fuel pressure for high powered K04 equipped cars (with HPFP). It has been proven to bring benefits for Stage 2+ ed30's :happy2:
There was a thread about it a few years ago where people with Stage 2+ K04 were experiencing fuel cuts at around 5200rpm, the valve solves this.
