Got the exhaust apart and sure enough both my cats are plugged solid. Now I wonder if I have any engine damage. :shrug:
Cats plugged solid
- Thread starter Blackmax
- Start date
Delete the cats. IMO nothing but trouble, an extra restriction, and additional weight. Let that baby breathe. Of course I have the luxury of no emissions testing in my area.
I suspected it was the cats, how do I know if I've damaged the motor? I hear its pretty hard on valves.
As long as she was running well before (ie no knocks or funny noises with decent power) I'd say you're ok. Were you any having symptoms before you removed the cats? If not, delete the cats and make a pull or two to see if she still runs well. If so, I'd say you're still fine.
If you are worried about engine damage, I suppose you could do a compression test on your cylinders.
This is why you guys are so important on these forums, I deduced it was the cats from reading here, my tuner should have known better as I described the symptoms to him over 2 months ago when I first starting losing power. I even told him the left cat was noisy and when we put it on the dyno it was 140 h.p. down. :bs:
Yes it has had a Tasca tune in it except for the track, I run my tuners tune.
See this what happens when you don't have an experienced tuner. Most don't have the knowledge of tuning a car properly. Your not making enough HP to mess up the cats. Let's take the Bugatti Veyron. It isn't clogging cats and makes tons of HP. I mean I'm just saying here.
^^^^^ this. Good way of detecting valve damage. Otherwise, remove the cats and enjoy.
Interesting. Were most of your miles with the track tune or Tasca? My impression was the cats weren't supposed to cook with a Tasca tune.
The last 16 track runs and 2000 miles were with Tasca tune. But I don't believe that means a whole lot.
Kind of freaks you out to find this, how the hell did the motor still run? And at the track at redline!
Both look like this...

That's disconcerting...good thing you checked. I'll have my car re-tuned with the stock cats due to some pending mods and with the SS JBA O/R pipe with the Shelby 3" exhaust in Sept.
