With the impending expansion of the ULEZ in 2021 to the North & South circular I'm trying to research if it's feasible with a change to the exhaust after treatment to alter the emissions of a Euro 3 K-Series to Euro 4?

I've read that once you improve the emission level you can get a LEC (Low Emissions Certificate) that is valid for a year at a nominal test fee.  Significantly less than the £12.50 daily charge.  I live about 200m within the South circular!

Euro 3 emission limits (petrol)
CO – 2.3 g/km
HC – 0.20 g/km
NOx - 0.15
PM – no limit

Euro 4 emission limits (petrol)
CO – 1.0 g/km
HC – 0.10 g/km
NOx – 0.08
PM – no limit

Dave Andrews or anyone else know if there is any work done on this yet?

Thanks

Alex

Invoices are being sent out this week.

I've paid mine, looking forward to setting a date for fitting.

Thanks everyone.

I've sent a DM to all those confirmed with next steps. 

If you could let me know when read and complete it would be much appreciated.

Hi Jon

Congrats on your purchase and getting booked in with Dave. Exactly what I did, you’ll not be disappointed.

I’ll ask about other people adding to the group buy as the minimum 4 is met, I don’t see why not! I’m having a cat integrated. I personally don’t want the faff come MOT time. 

Will let you know when I have more detail  

thanks

Alex

I’m organising a groupbuy for a powerspeed system, not asking for opinion or alternatives.

No of course I don’t but I’m not saying one is better than the other or making defamatory statements of the other.

I’m sure ME systems are as you describe, exquisite, and as their site is currently under construction I’m not able to see the Caterham examples you refer to, but the google images I’ve just searched are race car oriented with bonnet cut outs which isn’t an option for me as I’m not looking to re-skin but obviously have a more direct flow path, which might be why you say “their collector isn’t a good design”.

I’m an automotive design engineer with 20 years experience I’ve worked with both hot and cold end exhaust engineers many of which are petrol heads like us so have discussed this in great depth.

I've done my research, the PS system will improve airflow, reduces dB levels and meets my form and function requirements, not to mention they’re also recommended by one of, if not the most respected k-series tuners. That’s not to say if DVA were to update their website ME wouldn’t be there also!

I wish you well. 

Do you have Computational fluid dynamic analysis you could share to show why one is better than the other? or back to back ME vs powerspeed rolling road data?

This thread is a group buy for the subject system. Your additions are a little off topic and negative.

To date I’ve not seen a single picture of a Caterham with a Michael Edwards system. Their Facebook has some nice pictures though. 

Yeah I know, it’s taken me a while to bite the bullet.

Hi Mike

I'm just a customer with no commercial ties to Powerspeed, although expensive I think you get what you pay for.

DVA (well known and respected tuner) recommend Powerspeed and another one or two manufacturers.  Yes there will be others but I'm happy to go with a tried and tested formula.  Powerspeed are my favorite of what is available.

If you have a look at CC site vs Powerspeed the later is cheaper for what you get on a like for like basis.

Residual value is also something to consider, if and when I come to sell my car, having a Powerspeed system over another "brand" not synonymous with Caterham's in my opinion will not be as easy to sell.

Happy motoring.

Alex

Amazing - we now have 4 people on the list. Just need number 3 to confirm end of Sept.

One extra to follow at the end of year to also benefit from the GB. Will keep you posted at beginning of Oct. 

Cheers chaps

Alex

Michael had to pull out, so now 2 more people required.

Obviously a popular thread with 760 reads, can't believe it such a struggle to get 4 people interested/confirmed.

One more person required!!!!

Hi Russell

I don’t think so at this point. Just need 4 names to commit. We can then give our order specifics to powerspeed and make payment. 

I’ll add you to the list. 

Thanks 

Alex 

Anyone at all interested?

The sun is out and I would like to improve the mid range torque.

Is anyone else at all interested?

To close this issue off, I discovered that I hadn't seated the new horn ring far enough away from the steering wheel hub, so it was making contact.  I've now seated the horn ring right up against the dash allowing the required clearance to the steering wheel hub with only the spring loaded copper finger now making contact.

Thanks for all the input.

Ladies & Gentlemen

I am organising a group buy for a K-Series Powerspeed 4-2-1 complete system.  I've wanted one for a couple of years now and as they never really come up for sale I've decided to bite the bullet and get one made.

I’ve spoken with Lee & Andy and have the follow confirmed details.

We need 4 of us, so 3 more to get a 10% discount.

Full 4 2 1 System without CAT = £1500 inc VAT                   (Discounted price £1350)

Full 4 2 1 System with integrated CAT = £1680 inc VAT       (Discounted price £1512)

Fully polished = £200 +VAT

Free delivery or Fitting @ £200 +VAT

The non polished finish was described to me a being Scotch-brite "Matte", so you'll see the colouring of the metal where welded.  I've not got a picture to show this but they said it had a race finish and does look nice.

Payment or a deposit required from all of us before the first system will be shipped or fitted.  They have been let down in the past. 

Please only commit below if you are genuinely interested.  Obviously 4 is the minimum - more welcome.

Once we have a full list I’ll DM you all so we can agree a deadline to make the payment/deposit.

So who’s with me for a full system? 

1. (Me) 2004Academy80 - Full 4 2 1 System + CAT + Polish + Fitting.  (£1,992)

2. RussellS - Full 4 2 1 System without CAT + Fitting.

3. +1 will confirm end of Sept.

4. Chris whitlow Full 4 2 1 System with integrated CAT = £1680 inc VAT       (Discounted price £1512)

Highside43 - able to purchase at end of year.

Thanks

I found that lining the inside of the tunnel help a little.

Fitted this product under new carpet from Caterham (I used the carpet as a template).

There are also air gaps between panels and small holes in the foot well that allow hot air to flow in.  I'm going to use a foil tape to close these gaps off.  I'm also considering ducting cold air from the front to the footwell. 

For 14 years old it's holding up rather well.

Any help in identifying the ground wire would be gratefully receive.

Been a while, but I’ve made some progress. 

Switched relays and it makes no difference. 

Fitted new horn ring and that to, makes no difference!

So it seems there is a short circuit, where is the ground? locate?

FYI, it’s the top relay that’s doing all the clicking. 

Hi Phil

I may also be interested.  I've got a 2004 car so presume I must need to go down the CAT route.

Complete 4-2-1 with Cat, fitted.

Still looking - ideally a Powerspeed system. If you have or see one please let me know.

Cheers

Good tip, thanks.
