Anyone bought one?
I remember someone testing something similar.
Any feedback would be great :happy2:
Positives, negatives?
Ta V much.

I fancy getting the discharge and throttle body pipes as seen here:

Group buy :party:

i still haven't gotten around to take pictures of BN Autotekniks version of this upgrade, but i got 13bhp and 17nm from their version. :happy2:
-
im quite keen on the JBS version of the TB/IC pipe. it can be had with a bung for water methanol injection to save you drilling into an expensive pipe.
plus looking at the clips that hold together the piping for the discharge kit look very robust. this JBS kit definately looks better than the new speed varients.
other options are the SFS hoses which are 250 for the pair, but netted 10hp on chungsters before and after

Do those options have another "pipe" to replace the original outlet of the turbo? That's where the gains are to be had. not promising anything but hopefully i have pictures of the parts fitted to mine thursday. :drinking:
-
Hasn't Robin got this fitted, and also VrStu had it fitted to his Octavia IIRC???

Same thing....different turbo :happy2:
Just as happy for feedback from K03 owners too :ashamed:

....
Yes I've got the whole Neuspeed kit - Discharge and Charge pipes plus SAMCO hoses. Engine seems freer revving but not much else. I did it as a precautionary because stock hoses are potentially more prone to have problems with increased boost levels.
Rather expensive and with poor return (performance-wise) for the money in my case. I think there are possibly some better choices available now - As suggested in this thread.
I didn't do any dyno tests though.
-
iirc mater said he made 5hp from the neuspeed discharge pipe and nothing fromt he neuspeed discharge pipe.
from looking at the pics of the JBS id say they look a liittle better.
here is a pic of the SFS discgharge pipe next to the Oem pipe. which parts do the JBS kit replace?

here is the neuspeed varient

i dont get the neuspeed one. it seems as all they did was shorten the metal pie, throw some silicone at it, and increase the diameter slightly. then charg extortionate amounts of money for it.
I like the look of the SFS kit. the flow characteristics would be vastly improved over the others, but it does away with the metal altogether, hence why i like the look of the JBS kit. it looks that little bit more solid in construction
-
^^^^
Although I've got it installed, I don't get the Neuspeed offering either. I think Awesome were possibly trying to make their sales targets that month! As a result I'm now a little suspicious of most Neuspeed products.
-
i was going to pick the neuspeed one up back along but only as it was a second hand bargain, but i backed out when i saw the SFS offering as it looked like it made more sense design wise. plus chungsters before and after dyno runs showed a good gain.
the reason im stalling at the moment is i want water meth Inj at some stage. now i know the JBS IC/TB pipe can be had with a bung for w/m inj.
I wouldnt be able to do this with the SFS hoses as they are silicone, and the neuspeed one is a lot more expensive than than the others and id have to drill it so could never realistically sell it on. and the JBS pipe seems a lot fatter in construction.

Alternatively you can buy the 'JBS' parts from Eurojet (who manufacturer them) for half the price..

JBS sell it for £142 incl tax.
eurojet are knocking them out for $125 (£78) which is a big saving but doesnt take into account the delievery
ive never ordered from america before so if i was to buy that, would i get smashed with impot tax and delivery.
@JC
any reason why you are not running such a kit on your car. they must be better than stock and with your current setup every little helps with the efficiency i guess

True, just all adds up if your ordering lots of parts thats all..
I will be soon, just waiting for mine, should have some more news on it later hopefully :smiley:

I have a RR Graph of before and after the Turbo Discharge pipe was put on.
It didn't include the intercooler pipe as i have now Relocated the DV but the discharge pipe alone gave me 4bhp and 10lb/ft so i would imagine it would be somewhere around that figure for you Hurdy
See here:
Before Discharge Pipe

After Discharge Pipe

Oh and i know the RR Runs are 6 months apart but nothing else was altered on the car. I got the discharge pipe and added it. The car was still running Stage 2 REVO on settings B8 T5 F8. All other mods were the same.
The Intercooler pipe makes no difference (well not on my K03s Octavia anyway) which is part of the reason i relocated the DV and took it off (also because i have other plans).
But the Turbo discharge pipe definately gives an increase and i would expect it maybe a bit more on a K04 car.
@ Sy and RedRobin. The Neuspeed one removes the kink/curve in the OEM pipe so makes the airflow better hence the slight increase in power etc. Price i agree is too expensive but i didn't pay the full price.
Carl :happy2:
-
thing is carl there is 6 months between those two runs.
the difference could be due to the Discharge pipe, but could just as simply between different fuels, ecu adaption from when you first had your car set to revo stage 2, or just a difference in the dyno runs on different days (atmospheirc pressure, ambient temp, granted theyahve calcs to minimise difference) plusyou can chuck your car on the dyno and get 3 consecutive readings within 3-5hp of each other.
-
wow Carl , the torque peak looks to come in almost 250rpm earlier
although the plateau afterwards seems steeper ?
-
done within 2 hours on same dyno, only difference is BN Autoteknik Turbo discharge pipe and turbo outlet on K04 APR software.

Yeah it did come in a bit earlier Probably about 500rpm and The plateau dip is due to the wheels slipping slightly on the dyno (that's what Keith said due to the cold day.) the torque is higher from earlier on as well
At 2000rpm before the pipe was 180lb/ft
At 2000rpm after the pipe it was 210lb/ft
@Sy - The car is always run on V-Power and was on both those runs. The car had been on Stage 2 at that point for about 3 months so the ECU was well adapted. And as you well know from when i did the run in the second graph (as you were there) all four runs JKM did gave 256.x bhp (as the S3 cooler generally keeps the runs pretty consistent).
So maybe it could be difference elsewhere but i would be more inclined to believe (especially as i had a RR log done in the Nov in between iirc and that still gave 252bhp) it was the outlet pipe.
Carl :happy2:
-
not disputing it, just stating that is a possibility.
i dont doubt they would work, just a quick look at the stock discharge piping you can see the the amount of restiction there and the improvments that could be made.

....The supplier in the US will charge you shipping but will probably give you a choice of how. Faster costs more.
The UK will possibly, increasingly probably, charge you both handling and taliban tax (vat). Because of increased anti-terrorist security measures much more gets checked nowadays. Oh, and the UK system could hold it up a couple of weeks although the more efficient US system might get it landed in the UK in just a couple of days!
Sorry - I'm just telling you the worst case but it's happened to me quite a few times and it's best to plan for the worst. It's a lottery.
-
Some great info guys :happy2:
Just to let you know, I've taken a punt for the Neuspeed version and will be getting before and after dyno plots too. :jumpmove:
The Neuspeed one has a larger bore than OEM and isn't "squashed" like the OEM one.

you not going to look into the TB/IC pipe. alot of constriction in that pipe.

I have a Forge Twintercooler and only need the discharge pipe to mate up to it :happy2:
-

I have the Neuspeed version of that pipe Sy and it made no difference whatsoever to the output. I tried it when i was looking for the phantom stage 2+ problem and got the exact same Torque & Bhp as i did a month earlier.
I Still have it actually and might put it up for sale.
Carl :happy2:
-
the neuspeed one is still really constricted in comparison to the SFS and eurojet varients though.

-
lol, cancel my last then, the pic i saw looked remarkably similar to the stock pipe.
-
....
I haven't looked into the detailed comparisons but whichever kit anyone goes for they should make sure that the last section attaching to the turbo is that special heat resistant hose (Nomex) or metal, and not standard silicone or plastic.
