Here's a good video explaining their value on a direct injection engine. |

I can agree with both items (at extended WOT pulls) but respectfully disagree on not needing data. Everyone loves to post time slips and dyno reports, let’s see some posted up with and without a catch can / same car, same conditions.

Someone please provide performance data with and without a can, on a dyno same day. Then do the test again on different cars at 30k, 60k and 90k. I don’t care if others use a can, more power to you (pun intended). |

Ok... this was supposed to be a thread asking for advise and tips! Not a catch can war! Can’t we just agree to disagree? Anything else one should know about the ZL1 as a new owner? |

I will throw this out there now that I have a 2005 Silverado 1500 with a 4.8 liter V8 5 speed that I am the original owner with over 93,000 miles that has never had a catch can installed that still runs good and doesn’t use oil. It’s a LS engine design that I have never had any issues with in the 15 years I have owned it. I do use synthetic oil and decent grade of gasoline usually 89 octane since it has a SLP parts CAI, SLP exhaust system and a SLP Diablosport handheld tuner.

Squirrely, take your time getting used to the extra power of the LT4 and break in the engine per GMs recommendations and I think you will be okay! And yes the catch can debate is real touchy for some folks here but it’s a forum and I respect everyone’s ideas/opinions on them.

If nothing else, this guy is pretty funny. That’s it from me on catch cans! |

There is one thing, there’s a chance that under WOT, your rear end will feel loose and pull the car to one side or maybe back and forth. This isn’t caused by wheel slip (at higher speeds). There are plenty of opinions on the cause(s) here. One person said the tires needed to be replaced. More often than not, others have resolved the issue with an alignment (bad from the factory, rear toe related). Others have gone to after market parts claiming too much flex under load on the rear suspension components. I think all of the aforementioned are valid points. If you have the “wag” then you’re ahead of the game knowing what to look out for. Start with the alignment first... I have the wag, and will be hitting the alignment shop in the spring. |
