What can R-Tech do with this hardware?
« on: September 19, 2014, 10:36:37 pm »
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
