I have a Rotrex Blackbird engine....


And intend to build my car for road & competition use, ie hillclimbs & sprints.


Which CAT and where from please ? to compy with iva/msa regs....

Merlin Motorsports

thanks for that..


any others ?

But don't expect a cat to survive long on a BEC.
The 750 racers have trouble with their cats.

MNR fabricate their own so should be able to make you one to fit.

use a slice of zx12 cat, fitted into the end of the tail pipe

The whole CAt thing is a pain in the butt...


Volume cars yes, but realistically how much is motorsport and the home builder contributing to global warming.

Hi

As mentioned above take the advice of those running in RGB. They know what will work and certinaly what won't.

The whole thing with cats on competition cars was purely a Green Pr load of rubbish. The emphasis has now moved on from the pollutant side of things to the noise side of things. Hence we are now being restricted on noise pollution more and more and tyres are having to be made so we don't keep squealing tyres round corners.

Wouldn't surprise me if the MSA implement speed limits on corners next year to reduce the tyre noise. Would be about as sensible as trying to run a race car on a set of twin 50 webbers with a cat.

Cheers Matt

Thanks for that, I will have a look at the 750 site...

Your right though, its all pretty futile to me !
