Kooks Green Cats question
I'm looking at a bolt on ported blower build, no meth, no cam, no e85, with kooks headers, 2.30 pulley, and new heat exchanger with larger coolant tank at around 650/700 who, how well will the green cats hold up to that power and to being daily driven? I need reliability more than anything else.

If you are going to run cats, those are the ones to have. At your power level they will be fine.

Green cats will be fine with your proposed mods. In fact, you would most likely be ok with the standard Kooks cats. I've been running the "high flow" cats for 10k miles with the mods in my signature. I do run e60 almost exclusively which helps keep things cool. I read that std cats are good for 1500 F, greens 2300.

What would classify as road racing? Time? Track days? Speeds?

There's no reason to believe the green cats will not hold up if the car is tuned correctly, I believe each cat is rated to 400hp per cat so its really only above 800hp that they might start to become restrictive. That being said, I ran stock cats on my 1000hp Hellcat for almost 2 years without any issues and those were stock. The Kooks Green cats are made by GESI and are the best available, they are not cheap and they are very durable.

Another way of saying "I want more power conservatively as necessary". |
