Raceco CAT?

[u01rsb]

Afternoon All,

 

For next year I believe we need a CAT for all cars competing in sprints / hillclimbs with an engine younger than 1998. My car is a busa (BEC) with a 2001 engine and I have a lovely raceco can, I run in mod prods with slicks. The car runs great and therefore I don't want to put my CAT back in. Does anyone know if I could have a CAT put in my Raceco can in that way minimising changing my primary and secondary lengths and minimising exhaust flow disruption?

 

Are Raceco thinking about this at all?

 

Thanks,

Looking into this. One of the reasons for making the new exhaust system for the Duratec is that we can either have a long silencer for noise reduction, a long silencer with a cat incorporated or a shorter silencer with a separate cat.

 

Not decided what to do but something has to happen before next year.

Rob, the cut off for requiring Cats AFAIK is for a car manufactured in 1999, it may be registered in 2000 but the VIN plate will have the year of manufacture.

No idea about a replacement engine though 🤔

 

Sure someone will be along shortly to clarify

Ammo,

 

I'd like the same silencer I have now with a CAT incorporated if that is at all possible?

 

Personally I think it is B/S that this is going to be required for non-road going cars for next year as a CAT only works at specific lambda values which it is unlikely to see after it has been tuned on the rolling road.

 

However I know that some officials are going to be particular about this kind of thing next year so I should just get on and comply...

 

Thanks,

Are you sure the rule applies to non-roadgoing cars? I thought it was only for roadgoing classes.

I'm not sure no, neither was the chief scrutineer when I asked him on Sunday. But rumours in the paddock suggest it applies to both road-going and non-road-going.

 

I'd like to know for sure.....

Summer 2008 edition of Motorsports now (MSA bulletin) states on page 36:

 

"They are already in use within motor sport and with effect from 1 January 2009 they will be mandatory on all petrol engine production based saloon, touring and sports cars, including specialist production and kit cars, manufactured after 31/12/99."

 

There is a two page article on cats which, I guess could be posted, copyright permitting. Unfortunately the MSA haven't yet made this edition available on their website.

That sounds fairly unambiguous.

So a 2007 Caterham with a 2001 Busa engine and a log book needs a CAT?

 

It just makes no sense.

[Paul Deslandes]

As the MSA definition of Specialist Production includes non-road going categories so I guess the answer is "yes".

 

The rational seems to be that Motor Sport has a vocal number of detractors and it has to be seen to be cleaning up its act to minimise arming the opposition with arguments against us. They are therefore bringing road and non-road going production based cars into line with road car regs, similar to noise emissions. With some exceptions, most competition cars have to conform to the noise regs.

But my '95 1400SS with R400 engine doesn't .....

 

Keep off the straight and narrow 😬
