    Re: Lingenfelter High Performance Air Intake

    Jeff,

    Any reason why the elbow part of the intake was not replaced? I would much rather have the elbow you are using that is on the Lingenfelter shoot out car. Will this piece be available?

    Thanks,
    Shane

    I was gonna ask the question. The stock below hose looks very restrictive.

    The one on the SHoot Out car looks .......................sweet

    The factory one with the accordian elbow looks.................. well, like crap.

    The aluminum tube actually is prone to heat soak, and the factory piece isn't actually too bad. This was one of the more difficult air intakes to develope as the factory pieces are pretty efficient. Here is a dyno graph in which coolant temperatures were 192-194 degrees, no calibration work, completely stock CTS-V.

    Re: Lingenfelter High Performance Air Intake

    Jeff, we are referring to your tube (pictured below)


    Is that piece Aluminum? It looks like it's black plastic. Is that a LPE designed tube? You designed a tube but aren't selling it?? Or is itsomeone elses tube?

    ...very confused...

    Dreamin,

    When I spoke to Jeff about the intake this morning......(Oh yeah, I ordered one ) he said that the elbow on their car is aluminum and powder coated.
    He also said that it generated a LOT of heat. They only noticed a slight HP loss (less than 1 HP) with the stock elbow. I'm not worrying about it to much since the NEW Magnacharger elbow will work just right.

    Why wouldn't they make it plastic? I'm undecided now because of this. It seems like it would be the perfect combo.

    Tooling cost is what I was told. It (tooling cost) could cost as much as $5,000.00 according to Jeff.

    It's not only the 1HP. It would also look a lot cleaner.

    The black tube that you see in the picture of our original design was aluminum powdercoated black. The aluminum tube is prone to heat soak, and the power gains weren't justifiable in tooling a silicone tube like the GTO piece. We reuse the stock elbow in our system, and the factory pieces aren't too bad considering restriction.

    Re: Lingenfelter High Performance Air Intake

    Jeff, one more Q: Did you have a scanner attached during the dyno runs? Would like to know if you saw KR, reduced timing, etc on either or both runs... or if they were both perfectly "clean" runs (i.e. no KR, WOT timing 22*, etc.)

    All runs during testing were logged using EFILive. Each run was done at the same ECT (192°F -194°F). We would not use runs that showed knock retard for this comparison as they could skew the numbers. All runs used for comparison were "Clean" and the timing was identical. All testing was performed with the hood closed. Anyone who does not perform testing in this manner runs the risk of making false claims.

    Thanks Jeff... was NOT questioning your testing methodology... my car just made a lot more power and that was *with* knock... guess the power difference is dyno and engine variances.
