I just installed my new motor and want to do a lay down radiator. I have come across the Secondary Air Injection pump. I know what it does with the emissions at start up. I've read that it can be removed and have it tuned out. What have you guys done? Removed it or mount it else where?



Thanks guys,

I just took mine off.

Any codes pop up? Did your check engine light come on?

Paul Schmidt

Anyone else can help me out on this? Any tricks on making this happen with out a check engine light? I'm about to remove this and just want to know what to expect.

Thanks

block off plates on the exhaust manifolds, all AIR stuff in the trash, just remove it in tuning

Removed it and the plumbing on engine. Never had a code and it was not tuned out to my knowledge.

Ditto.

You guys are the best

Let's us know what happens. Can you weigh just the pump? That would be great.

Thanks,

4.6 pounds


2.2 pounds


6.8 pounds total.

I also ordered LS1 AIR Block-off Plates for the headers.

I wanted to take just the pump off. If I need to smog it, I could just put it back on and leave the hose in place. Would I have to plug the hoses going to the pump?
thanks,

where do you get the block off plates from?

varkwso

I used a gasket and cut it out of a piece of stainless. Regular steel will be fine also.

Thunder Racing sells a block-off kit. Just remove it and cap the vacuum line. There's a check valve in the system that can throw a MIL. I had any related codes turned off with my tune.

I believe the PCM can sense the extra air via the O2 sensors, but as stated your tuner can block the codes.
