I just supercharged my 2006 cobalt SS automatic 2.4 liter. I used ZZP's supercharging kit to supercharge it. The one issue I am having is when ever I try rev past 4,000 rpm the engine pops and wont give power. However, if i keep the rpm below that I am not having any issues. Any idea what the issue might be?

Thanks!

 

Why do you want to rev?

 

In general when I try to do a 0 to 60 the car revs past 4000 rpm which is when this issue occurs.

 

Try posting a video of the issue. Hard to say without seeing it.

 

Here is a video of the problem.

 

What intake do you have?

 

ZZP intake tube with K&N filter

 

Okay cause my 2.2 was s/c an I had that same problem when I had a eBay intake on it, I switched to the stock lsj intake an it went away

 

Do you think it is the filter that caused your issue or the tube leading to the filter?

 

I would stop doing that. What's the afr when that happens and what spark plugs are you using and what gap?and what tune?

 

Oh trust me I am only doing that for the video. And I am using a zzp tune and the gap is .041

 

I think my issue was that eBay intake has the maf in the wrong spot. Try closing the gap on the plugs an is it tuned for that intake

 

Well there's the issue. That gap is way to large. What size pulley are you running?

 

Put stock lnf ac delco plugs in it. What plugs are you even using?

 

The size of the pull is 3.1 inches. What gap do you recommend?

 

The plugs that came with the kit.

 

Just put the stock lnf plugs in it. They come gapped at .035. Been using them for almost 2 years.

 

Pretty sure what you're experiencing is spark blow out.

 

Gotcha. Will make the switch and see if it fixes the problem.

 

Ya. The gap you're running is pretty much stock.

 

I switched to the stock spark plugs and the issue is still not fixed. Here is a video of it now.

 

Why you put stock plugs in?they are gapped at .040 something. You need like .035

 

Oh gotcha. My bad. I'll make the switch.

Thanks again.

 

Yes stock is .043. Even larger than the ones you had. This is the part number you need to get. 41-108

 

Even with upgraded injectors and running premium these sparkplugs will work?
