FAB speed sport CAT review for F430 - The CAT become glowing RED hot

wow

 

more Wow!!!

 

my Scuderia stock cats get glowing red just coasting on the highway, if I drive it a little harder, when I park it in my garage, the entire garage feels like a summer day in Death Valley.

Normal.

 

I have cat by pass from Capristo and I send them to coat with ceramic to prevent FIRE IN THE DISCO !!!

 

just had fab speed headers installed on my 430 ...no isuues like that but i do notice some change in color under hard driving

 

I used this in my cat by pass.

My Kinetix sport cats glows only after aggressive driving. I think it looks kind of cool! I would make the cat more visible if I am the designer. Imagine people see you arriving with a glowing engine how cool is that? Engine led is silly

 

True, those sensors should reading a over heat temp.
You always can wrap the headers or put a coating on it.

 

Maybe after some hard laps in the track you have to do 1-2 cool down laps,thats what i do and never had red cats.

 

Point of order to clarify...

If a "single drop of petrol" touches anything over about 540F, "the whole car will be in flame"
as that is the autoignition temp of gasoline.

Essentially, that drop can hit anywhere on your exhaust system and you'll have instant ignition. It doesn't have to be glowing at all. boom.

Thus we attempt to show that one should use most care in keeping the fuel inside the fuel system at all times

The Fabspeed guys will probably chime in soon.

 

Suggestion... are BOTH cats red?

Do you have access to an IR temp gun? What's the temp of each cat after a run?

A normal Cat temp will be anywhere from 300C to 900C

In "color" that is "nothing" to a good "Cherry red"

Maximum temp is listed (in the F430's calibration) at 1200C or so. That's "reddish orange"

I don't know the construction of the Fabspeed cats, but if there is no - or little - insulation
between the matrix and the visible shell, the outside can easily reach "glowing".

Jim

Addition: at the normal exhaust gas temperature of 400-600C, metal will glow red "in the dark".

 

I did not meant the o2 sensor , can you tell me what is the other sensor atached To the manifold, cats or exhaust? No the air/fuel ratio? It is the termocouple next to the o2 sensor.

 

400-800 C

 

David,

Yes, EGT under load can be higher than 600C - wasn't my point.

My point was that the OP is showing his cats glowing slightly "in the dark".

This is nothing worrisome or unusual for "non-insulated" catalysts.

If you can see metal glow red IN THE SUNLIGHT you are at about 550C or thereabouts.

by 600C it's clearly visible.

(For photo buffs - you are sitting in an EV15 environment, and you can clearly see a red glow even though the item is in direct sunlight)

If your catalysts are "lit" they will be at or above the nominal EGT, since they are taking in reactants at the EGT and catalyzing an exothermic Redox reaction in-situ.

Thusly, every "non-insulated" properly working catalyst is in fact "glowing in the dark".

OEM headers and moreso catalysts usually have insulation on them.

Jim

 

Totally agree!
I think a heat gun should be a great tool for troubleshooting. Like you said the gun should be reading between 400 - 800c more than that can tell you that if the EUC don't sense it for sure the thermocouple are damage.

I'm gonna pul tbe trigger on a set of Fabspeed test pipes so can someone tell me if they will end up glowing red like the cats? I guess not coz it should actually reduce in temperature since most of the gases get pushed out to the mufflers.

 

They wont get that hot. I think Pat possibly had other things going on to cause that.

 

Does anybody know if the Fabspeed cats are 100 cell, 300 cell or what?
