250NM..at least, anybody out there with a tuned 106hp version of the 1.5DCI? Standard 197 already has 215NM, so I expect the turbokit to take it to at least to ~300NM. The 6-speed box in the Megane is not a TL4?

As per title; was wondering how much the gearbox can take? And with 'can take' I mean it's good for at least 70k miles and you can just always use all the available power in every gear. Reason for asking; The main thing I don't like about the 197 is the lack of torque in combination with the...

Getting tired of those silver seatbelts which always seem to look dirty, is it easy to change the seatbelts to the normal black/grey one? Can you just order seatbelts from the non-rs version? and of course how much €€(or £ in your case)? Thnx.

Exactly, strange thing is; outside that speedrange it's still loud, but just nice and raspy instead of boomy. You have the road-version? I was hoping that that one wasn't so boomy at those speeds :dapprove: . Not that it is going to help you (being in the UK), but my Renault specialist has a...

It won't pass the dutch MOT, don't know about the UK MOT. The sound is indeed truly unique, when you're in the mood it's lovely. But living with it day by day (especially when you have passengers) becomes tiresome.

I have the non-stainless steel race version; it's the lightest exhaust by miles, the mounting (of the single backbox) is superb, there's a sportcat(100 cell I believe) included and you do feel a noticable gain, haven't had a before/after RR though. But it's unbearable loud (especially at legal...

Officially, my Orbisoud was €1700 (the race version, which isn't even made from stainless steel :eek: ). Bloody expensive, but when you look at the system, the mounting plates/points, design(single backbox), weight, etc. it makes some sense. It's unbearable loud on top of it! Love it though..

So, it has for sure nothing to do with enhancing the rigidity of the chassis (even as a side-effect)? I'll take it out tonight if that's the case..

Just do a Group N remap, problem solved (in my case anyway).

Nope, park a 197 next to a 1*2 and you see my point. Even the most basic cars today (like an Aygo) have bulging arches, needs more then that to stand out from the crowd these days.

I always thought the front/rear brake balance was variable? In the wet there must be less braking on the back then in the dry.. Don't know how the system knows how to adjust the balance depending on roadconditions though..

It seems the Mk3 Ph2 is going back to the Mk2 Ph1; the closed front, the rounded flat headlights.. Agree the Mk2 as a whole looks dated; low waisteline, narrow arches, it has no roadpresence at all..still drives damned wel though :) .

I've had the decat removed/fitted a few times now; before grp N mapping, after grp N mapping, etc. I'm convinced it loses quite some torque lower down the rev range and no gains top end either. It's a shame because I love the sound of a decat (with a Milltek). No RR data to prove it though, so...

Hi Frank, Could you please count me in on this one? If Henk can do the total job, that's perfect.

I've got a Milltek, it has indeed a nice bass sound to it, not loud with a cat, but with a decat it's quite a bit louder (bit to boomy for my liking). I'm not satisfied on how it fits; first of all you need to fill up the rubber spins it hangs in, otherwise it's hanging way too low. I also...

The standard alu pedals really annoy me. You keep sliding of it when your sools are wet. Trying to dry your sools on the mats is useless as they don't absorb anything. I'm sure I'm not the only one with this issue, are there pedals that contain more rubber? Or mats that actually absorb something?

Can this resistance on the end of the accel pedal be removed? Don't like it at all and I never use this speedlimiter nonsense anyway. There must be a spring or something which creates this resistance :S ?

Changed my tyres from front to back once, back-end was all over the place even when going really slow. First corner out of the garage and it just spun 180 :S .

Wish I thought of number 3 (about matched rear lengths) before I bought my Milltek. It irritates me big time that the right exhaust puts out far more gasses then the left one :( .

The shift light tells you the most economic time to shift, that's why it's green..:clown: . Just buy an Aygo when you're worried about fuel consumption.

Jesus, I'm stupid! I thought you meant some enginering god at Delphi automotive systems, even after reading that it was some old greek tart, I thought; 'hmmm, well, that's unusual that this engineer is an old Greek woman' :clown: . But now it finally got it, you mean this ancient Greek sh*t :o .

http://www.superchevy.com/technical/engines_drivetrain/exhaust/0505phr_exh/ A long and complex bit of reading, but some very interesting issues: - The so called 'scavenging effect'; this effect occurs when the intake and exhaust valves overlap, the vacuum at the end of eacht exhaustpulse...

Thnx Fred, but if I follow your 'less backpressure = more bhp' explanation, why is it when you take off the complete exhaust, it loses so much power (unless that was a perception too:S)? doesn't make sense..

That's why I mentioned parameters staying the same, but I agree it's quite hard to achieve that. Anyway; for the moment I trust my perception, to little backpressure is only going to give you losses imo. I'm convinced by this theory, because my exhaust broke off once and the car almost lost...

I was thinking about that either, but the perception is quite convincing tbh. Are there any before and after cat/decat RR graphs available (where all the other parameters stayed the same)?

I'm putting my cat back on, it's just gutless on torque lower down the rev range since the decat. Don't think it gained any power top end either. (this is in combination with a Milltek cat-back)

These are very crude, restricting the flow almost completely. This is much better; http://xforce.com.au.tmp.anchor.net.au/cars/view_car/29

Indeed, especially with a decat it's just loud!

Can someone in the know please explain what kind of function backpressure exactly has (i.e. what it does with escaping exhaustgasses) and how it effects power/torque. I always hear that less backpressure = more bhp, but once my exhaust broke (just before the cat), so it had no restrictions...

Greeny; regarding the carPC, if you have some €1400 lying around, this is nice: 1 din format PC including motorized touchscreen.
