Mate of my brothers paid nearly £2000 for a clutch and flywheel change from a main dealer for his 350z (despite me sending them Zmanalexs contact details - fool!) so hardly cheap.

My R33 and VX220 were both as good performance as my zed (better than the zed in many respects actually - both the VX and GT4 have much better mpg as well) never got any hefty bills for either over and above the Zed cost. Looking online at the GT4 (again very quick car) costs for parts are on par if not lower than the Zed - it actually seems quite expensive compared to those cars especially the VX as that uses standard vauxhall astra parts.

He can stick around but not as leader, all a bit pathetic really, he said he would resign, thats means go, leave regardless of what his employers say. I would imagine the other parties will tear strips off him for years over this.

Of course a drift car will be performance over style...I would be surprised if anyone went the other way - however on here with peoples 'pride and joys' all I ever see with regards to exhausts are the sounds, hell there was even a thread arguing if single exit or dual exit looked better and influencing purchasing decisions. The percentage uplift is useful and another way of expressing the actual BHP uplift, my point stands that is that peak gain is not particularly useful if you are wanting to gauge your uprev performance.

In terms of area under the graph, yes that is true it gives you an even truer representation of what you have gained but that wasn't the issue - the question was why are the print outs showing peak power gain, my point was if showing a single figure that you want to interpret then average gain is more useful. In terms of area under the graph is it 'day to day useful' - can someone understand '8bhp gain on average across the range' easier than 'total area gain of 125bhp2' as an output, I would say in most instances they can. Its by no means the most accurate way to report it but its the most usable. When presenting data its often good to present quartiles, max, min along with some sort of score on the middle ground such as mean or median, all covered in your GCSE course. Your big arches were performance mods were they...? Maybe you are a departure from the norm then and somewhat of an outlier but most people that post on asking about exhausts invariably want to know what they sound like before buying, which indicates it not all about performance.

Bingo! I wasn't having a dig, I am a consumer researcher with a statistics degree, so am annoyingly finikety with how data is presented

misses out 75% of the numbers? I dont understand this Coldel? Sorry yes not a very good description! The scale runs from 800 to 1100 making the gap look big when in fact it is quite small, the same goes for the BHP it starts at 50, if you start it from 0 then you 'visually' see the true difference. Appreciate though that this helps reading the charts easier. Just in terms of what your remap gets you, I think everyone quotes 15-20bhp when in fact a more truer read is the average across the range (would be a nice number to have calculated on the software).

Cheers mate, I do have to pinch myself regularly to realise that I have been so lucky to pick up a great example Probably going to put on the tein springs in the next month or so...doesnt really need coilovers, its just had a whole new suspension set up put in so seems a shame to replace it so soon.

Used it on mine, rears were quite easy with a little bit of heat. Here is mine with it on the back

To be honest other than a plenum spacer thats all you need, should be good for 15-20bhp increase

Absolutely, there is no point in considering an exhaust purely for performance, which is why the exhaust note is so important when purchasing - same for induciton - I think the given knowledge is that the standard box is the best for performance yet everyone likes to switch to something else just for the noise.

Thats just a bit weird!

My point though is that when people say they get 15bhp from a remap they often refer to the max gain, the average gain is often quite a lot less. Hence the placebo effect. Have to be wary also of the visual impact of the charts, the curve on the left for instance misses out 75% of the numbers, the difference is actually relatively small. Although the cost of the remap is relatively small you could say i.e. £350+ most people spend around £1000 on an exhaust, induction kit etc to get that 8bhp extra on average across the range.

Ha! Surely the bit you are really looking forwards to!

Found mine! Packed away on photobucket...so my point is really that between 1500 and 4000 revs you are seeing a much lower gain in BHP, if anyone thinks they can feel more power on a 250bhp car because they have gained 5bhp at 2000 revs they clearly have super senses in their backside All the gains happen much higher up the range, it did flatten out a dip around 5300 revs though. Average gain over the whole curve, at a guess 10bhp? At the most used lower end a bit less.

Some more pics, had a nice drive out this morning. Also confirmed booking on 26th at TGM to sort the bonnet out so happy days. Definitely needs a little drop on the ride height...

And to think red doesnt always come out great on camera, so this must look even better up close. Outstanding effort Darren, still in awe of people that have the ability to pull cars apart and put them back together again!

837k is well above the statistically valid sample size for the UK population, with a 98% confidence level and 2% margin of error. I get your point about the conclusion I have drawn from the numbers, but if it was "untrue there is any correlation" why would the press bother front paging election coverage? Sample size is irrelavant if the question is asked badly or the framing is wrong - the Greens and Liberals have policies which are in lots of respects very pretty policies but would bankrupt the country if put into play - so of course blind voting on policies will always go for the more people/environment orientated policies. As for the sample size of 800 odd thousand, that sounds like something done for free, online, in some space where millions of people go i.e. facebook, which already biases the results as you are not getting a representation of those who dont use facebook regularly - so how much stimulus could you have given people to answer the question correctly and remain engaged? Probably 30 seconds worth? Thats hardly representing the policies fully of each party. Unless I can see how this question is asked to be quite brutally honest with you the data is worthless, despite the sample size.

So its going to be red...? What you up to sunday morning mate? Am going out for a drive and wouldnt mind popping by...

I don't object to cuts to public sector funding per se and I certainly understand that there would still have been cuts had the Tories not got in. I am however concerned that the cuts under the Tories will be so severe that services will suffer, be it education, justice (my area of work) or services in any number of other areas of life that people rely on. I've already seen the department I run reduce in size by more than half since the recession began. Any more and we simply won't be able to deliver the work. I feel equally for people in the private sector (my other half works for a private company). It's not been easy for most people in recent years and I doubt it's going to get much better for a good while yet, despite all the political rhetoric. Lots of private sector companies took cuts as well, job loses, spending cuts - the government generally did nothing unusual in terms of how the private sector had to react to the downturn in the economy. Lots of people (myself included) are now doing two jobs not one.

My import says GT4, therefore conclusion is that you are driving around in a Nissan Cube

Al Murrays face when the tories beat Farage in Thanet...brilliant https://www.youtube....h?v=xuzlKi-5qFE

TME what a piece of machinery that is
