Philip Posted March 23, 2009 Share Posted March 23, 2009 POBC - 1st MOT on the Toxic Frog (oh, the irony...) for me, never had to think about getting a car through an emissions test before . Wisdom seems to be that fitting a cat may not be enough to get my 98 SLR VHPD through the emissions test. Is there a concensus on how this can be done ? I'm fairly dumb when it comes to all this ECU trickery - why should it not pass with a cat ? Strange one - did factory cars leave without a cat fitted ?

Mr Locust Posted March 23, 2009 Share Posted March 23, 2009 Worth a read here to see if you need a catalyst fitted first. Ian Green and Silver Roadsport 😬 Link to comment Share on other sites More sharing options...
Philip Posted March 23, 2009 Author Share Posted March 23, 2009 Been through it with a fine tooth comb - looks like it (factory car, post 92) , plus tighter emissions Dayglo Yellow / Carbon Superlight R No.29 (VHPD) Link to comment Share on other sites More sharing options...
CageyH Posted March 23, 2009 Share Posted March 23, 2009 Just got my VHPD through an emissions test using an Emerald K3, and wideband lambda.

Diff Posted March 23, 2009 Share Posted March 23, 2009 Hi, I will be putting my Feb 98 VHPD through the MOT in May (1st time in my care), it has alway got through with a visual inspection. Checked the VIN numbers and according to the info on the link above it was not fitted with a CAT. I am not sure why. Does anyone know? Should I be concerned Link to comment Share on other sites More sharing options...
MADMALC Posted March 24, 2009 Share Posted March 24, 2009 Anything up to and including 'R' registration is visual. 'S' registrations need the cat and will be tested for emmissions. (I understand if you can prove the engine is older you could get away with visual but we need more expert comment on this) My SLR was SVA'D with a cat and passed the test. Needs to be very very hot.

Brucey Posted March 24, 2009 Share Posted March 24, 2009 Philip, Put some injector cleaner/emmisions reducer in with a tank of posh petrol, Take the car for a good thrashing up and down the motorway. Make sure the engine is nice and hot when they check the emissions (ask them to do that test first). The worst that can happen is that it fails, but the above usually works for me. Good luck, Bruce.

CageyH Posted March 24, 2009 Share Posted March 24, 2009 Mine was fitted with a Cat. Emissions test was last, and it still went through. I have set the AFR to 14.7:1 at all the test sites though. Only dead fish go with the flow....! Link to comment Share on other sites More sharing options...
Philip Posted March 24, 2009 Author Share Posted March 24, 2009 As car was factory built, cat is required. Caterham do not have any in stock (6-8 weeks was being generous - Darren thought the 'special' VHPD cats means unlikley order... ) So - has someone got : 1) a spare Cat for a VHPD 4-2-1 system ? or 2) a spare K cat-equipped exhaust for "temporary" purposes ? or 3) 7-friendly MOT station in Scotland.... Getting desperate, as I cannot bear the thought of the car being off the road waiting on an MOT Dayglo Yellow / Carbon Superlight R No.29 (VHPD) Link to comment Share on other sites More sharing options...
