PICTURES of Catalytic Converters

John Lowe

Hello All

I am close to finishing an RCR40 build in the UK. Motor is a Chevy LS7 with Kinsler stack EFI which means CATS to get through the IVA. I think that the LS (or other modern V8) are fitted to a number of 40s in Australia, also requiring CATS.

It would be most useful for me to see some pictures of similar installations of CAT equipped cars. Thanks in anticipation.

Excitement mounting, 560bhp, 1100 kilos, on a track, oh sweet joy.

Regards to all

John

Re: PICTURES of CATS

Thanks guys!

I took your collective sound advice and tested our Moggy in the oven to see if emissions were reduced.

Tests were inconclusive as the oven door was ripped off its hinges, my right arm was badly lacerated (fortunately the surgeons managed to save it) and the cat is in a complete sulk and makin' everyone's life a misery.

To the guy who does'nt like cats.

They Dont Care, they are masters of all they Universe. As Churchill famously said "Dogs look up to us, Cats look down on us, only Pigs treat us as equals.

Anyhow, many thanks to Frank Catt, clearly with a name like that a discerning engineer.

Ho bloody Ho

Rick, only the thumbnail of the image came through, not the image itself. Clicking on it gets you a tiny representation of what you're trying to show us.

Try again? Also, would you mind e-mailing the original image to me? I'd like to share it with some cat-loving friends. My e-mail address is just below here. Thanks!

Re: PICTURES of CATS

John, attached are a few pictures of how we have set up the exhaust system with cats in my car. The wxhaust boxes have been placed in the area where the luggage carriers were located in the MK11. It is hoped as well as meeting IVA requirements that it will enable entry at some of the quieter trackdays. Time will tell as I am just waiting for the EFI to be mapped so we can get accurate emission readings and noise levels. Also need to look at heat shielding for the cats which has not been done yet.

Hi Rick

As I have always said

What is this... how come you never see stuff this sick and mean about dogs? Why is it always about cats?

Reverting to the other cats, the converter type, has anyone ever had to replace them due to them wearing out? There were dire predictions of expensive regular replacement when they were introduced.

Getting serious now, on the way home from the national Pantera meet one year, I saw an '86 Corvette stopped dead in its tracks in the middle of the Mojave desert, when the catalytic converter came apart and completely plugged the exhaust system, like a giant internal cork. BLEAH and the car just quit stone dead in the middle of the road. Took some doing to diagnose and fix it.

Serves the guy right for leaving his Pantera at home! :laugh:

Catalytic converters will also lose effectiveness and/or become plugged up. Usually their change is precipitated by a smog test failure and/or a noticeable falling-off of performance. They can become plugged up over time, and/or fail to 'scrub' the exhaust gas clean enough for the government testing nannies.

Having said that, it's unlikely that you'd ever need to replace catalytic converters on a car that would be driven as occasionally as a GT40 replica.

I think Jim, it is because cats love us on their own terms. That is something some people can't accept. However, as Aldous Huxley said: To his dog, every man is Napoleon; hence the constant popularity of dogs.

My cats have me exceptionally well trained, but I admire them for that.

Re: PICTURES of CATS

not on a GT40 but a surprise on my Hartge Z3 when I had to change my cats because they were worn out...it blowed the expensive inside stuff out over the years (sport-cats) also blocking the air stream some years :-( I discovered to late)

but I wanted to show it as a maybe possibility for some GT40 owners? because those were not only cats but also little mufflers...(did not know that so now I only have 2 sport cats)

the in going side is cat and the other half is muffler see pics of those cats, Hartge did that nicely back then in 2001 or so.

the cats took a walk ;)

and here the other side the muffler side

this way you can see why I felt power missing specially at the German Autobahn and the engine got hotter and so les power because for 2 years the flexible stuff inside blocked the airstream...and then I discovered a while later (when it was almost gone) little pieces of that stucked in the rear end of the silencer and then I start wondering :D now with 2 new 200cpi cats its power back like when I bought the car but a little bit more sound because now I'm without those short front mufflers, but the sound is still fine for now because the cats work a bit better :D
