LS6 intake results not good!
LS6 intake results not good! I installed an LS6 intake on my car and the results show I gained nothing. Apparently even lost a little.
Two weeks ago I ran an 11.978 @ 112.74 mph. Installed the LS6 intake, last night ran a 12.065 @ 112.63 mph. The weather conditions were almost identical. Both runs the temperature was 66 degrees. Humidity last night was up to 78% verses 60% and the barometer was up to 30.06 verses 29.95.
I am wondering if I bought a standard intake. It has mold number 12573572 molded on the manifold. Is this really an LS6 intake?
I have an LS6 cam and ported heads so surely I should have gained something. My heads are self ported but they were dynoed to gain 20 hp so they do flow better than stock heads.

Re: LS6 intake results not good! Larry, was the bottom of the intake FLAT? That is the most surefire way to tell...the LS1 intakes are concave on the bottom allowing the coolant line to run beneath it where as the LS6 is flat requireing you to go to the 2 seperate coolant lines....
Re: LS6 intake results not good! JoSeY,
The bottom of my new intake is flat. I looked it over real good before installing it and this is about the only difference I could see. I did use the plugs and coolant bypass tube.
99taws6,
Last night: 60' 1.675, 1/8 7.692 @ 90.10 mph.
Oct 16: 60' 1.659, 1/8 7.713 @ 90.19 mph
There has been no programming since the install. I had about 60 miles on the car with the new intake.

Re: LS6 intake results not good! it will take around a couple of hundred miles to realize a difference bacause the computer has to get use to more air flow. it should be straightned out after 500 miles. You live in sugar land so just come into town an run it around 610 a couple of times. Instant 500 miles <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> but anyway where did you get it from

I bought it off of Ebay. It is new and never installed and was sold as an LS6 intake.
Surely somebody can identify that number?

Re: LS6 intake results not good! Well 12573572 is not a current GM part number. Not sure what you got, but I tend to think it is an LS1 intake. That is why I never buy off ebay <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
Re: LS6 intake results not good! I have both intakes in the garage and it's neither one. GM did change the #, so it could be an older one.
BTW- Where did you get it from; Miami Motorsports?

Re: LS6 intake results not good! If the bottom of the intake is flat then its an LS6 intake. I know that for sure. because the LS1 intake has a valley for tubes to run underneath it, you gotta drive it more so the PCM can get used to it.

The manifold is flat on the bototm and some have said that only LS6 manifolds are flat. I still didn't gain any et though!

Now to find out why I lost et. As some have said, I may have tuning issues to deal with now.
Thanks!
