We found that it was just to big and the huge lag in preasure caused the turbo to stutter, not spin smoothly and lag was increased and with a lose of power at the top end. Cars feel quicker with it as you get a big wag of power delivery in the middle but poor low down and top end.

Was this on a standard ibiza cupra or did it have other mods aswell?
 
The car we used had only a stage one map. But that was not so important. What we did was take the flow we have on the cylinder head, exhaust manifold and the turbo charger (up to its maximum flow rates) and found that it was not possible for it all the breath (flow) enough volume to warrant anything bigger than 2.5". We found that a K04 turbo and the better exhaust manifold attached as standard, when running increased boost that this would warrant the larger diameter.

I hope this helps.

Each to their own like i said before but i know my car performed better with the larger diameter dp & cat.;) Quicker spool up, more power and more torque. The gains weren't just at the top but all the way through.
 
Indeed :) Its not so much about the bore of the system its also the silencer placement and design of the silencers used. All need to be matched to suit a given application. Its quite hard to get it right but worth it when done :)
 
dont meen to sound stupid but i want a turbo back blueflame exhaust for my lcr but dont no were u get them from. could some1 please tell me?
 
They are known to be a bit inconsistent with their prices but expect to pay £575-600 for a turbo back Blueflame with 3" DP and 200 cell race cat
 
Blue Flame have an ebay store, full list of applications and prices are on there
 
Sorry to drag this from the depths but Piper are absolutely correct in what they say, I'm not biased as I'm having a full Milltek system fitted next week as I had the cat-back system ona previous Cupra and thought it was superb. A 3" from the turbo back on a K03/K03s turbo will produce less torque than a 2.5" system on an identical car, this is a proven fact. The 3" will be better than the standard exhaust but not as efficient as 2.5" aftermarket (Piper/Milltek) downpipe.
 
MY car made more power and torque with a 3" on. And thats fact! The car also drives better and gave it better power curve. Not just a top line torque figure!
 
I think there's some confusion here. The Blueflame system is a 3" downpipe that tapers down to 2.5" to adjoin the cat, where the rest of the system in 2.5" all the way back - the same as the Milltek

I'm not saying otherwise mate but with an optimal map, a 2.5 inch downpipe on a K03S turbo will make more torque with a flat spread than a 3 inch in the same situation.
 
All I can say is that I have the blueflame turbo back exhaust fitted (inc. 3" downpipe and cat) and I love it.

As far as i'm aware, turbo charged engines are happiest when there is very little back pressure. N/A cars are a bit different but we won't go there now.

Surely a bigger downpipe would reduce back pressure?

Just my 2p's worth.

What's the theory behind this? Not having a dig or looking for an argument, just looking to learn that's all.

So your saying that if my car had an OPTIMAL MAP it would have made better torque with the 2.5" than the 3"?? Just for your info my car was mapped with the 2.5" fitted so that kinda blows your theory clean out of the water!
