    20 rwhp & 25 rwtq bolt on gain...



    Love the DI motor and the power were making, but the heat soak intake manifold up through 2011 leaves alot to be desired.

    Thought I'd share the latest power solution.

    Did before and after dyno with the motor heat soaked well before & after the swap.....far greater gains than expected:

    Graph looks like heck pulling in 3rd gear, 4th gear hit the speed limiter (no tune on the car) as you can see and only went to 5800 before limiter kicked in:




    Going to try it on the supercharger build to see how well it works with a boosted application.

    I'm not sure what we are looking at here, is this like an intake manifold spacer/insulator?

    That's what I thought too. Looks like an intake phenolic spacer.

    It is a phnolic spacer, 9.75mm. Uses the OEM manifold gasket on the bottom, permatex right-stuff on top. Stock bolts fit.

    Here is the link to buy them: http://www.camaro5.com/forums/showthread.php?t=203387

    The first graph is 3rd gear and the Bosch ECU/knock sensors pick up a resonance on a chassis dyno that keeps pulling and putting back timing.

    The 2nd is in 4th where this does not happen, but you hit the speed limiter at 5800 rpm (no tune so limiter is at stock MPH).

    No tune, no other mods, just the spacer. Mike Norris shop in Indiana found 20 rwhp & 28 rwtq in their dyno tests and they did before, after, and back to before to verify further.

    Damn tempting. Iv'e got the Trifecta tune on order, so paired with this, we may be on to something. Add a CAI, and now we're talking....

    But instead of this product gaining power, would agree that it's really only allowing you to maintain the power that you currently have? Since it's keeping radiant heat from the cylinder head, out of the intake, the ECM isn't retarding timing, therefore keeping power levels up, but not really a power adder. Either way, it sounds like a must have.

    Will the Cadillac engine cover be able to stay, or have you only tested fitment on the Camaro?

    Need a test mule?

    The CNC ported throttle body cures the dead spot between 1200 & 2400 rpm as well....if your in FL yes, look me up and will see how it fits. The cover is barely fitting on the camaro.

    Yes on the heat. The same as my Dodge Viper used to gain 40-50 rwhp by icing the alum intake for 10 minutes after a heat soaked dyno run. By the time your ready to drive after start up the IM is already 30*f hotter than w/the isolator. The 2012 LFX has a composite so not much improvement on it.

    Eliminate the oil ingestion into the intake air charge and there is alot less detonation causing the ECU to pull timing so that improves fuel economy & power as well.

    I'm definitely interested...that is a ridiculous $/hp ratio. Post says only 2010 and 2011 though...I wonder if they work for 2008 & 2009s?

    Unfortunately I'm in Maryland, so a drive down isn't in the cards. However, I'm still willing to test mule the product to see how she fits on the Caddy. I just got finished adding the Trifecta tune tonight, and I'm very happy with it. I'd love to see what happens with your spacer.

    Also, talk to me about the CNC throttle body. How many millimeters is stock, and how many millimeters is yours? Does it keep the same outer diameter as stock? What gains are we looking at?

    Not a whole lot of V6 Caddy performance modding going on in here, outside a CAI. You can see my trifecta thread here:

    Re: 20 rwhp & 25 rwtq bolt on gain...

    PM me your contact shipping info.....if you have access to before & after dyno I'll send you one free.

    The TB is a stock unit with CAD designed patterncut to break up the surface tension and straighten the air flow. It only gives 4-6 rwhp gains, but the off idle throttle response and low RPM gains are very noticeable. I will send one to try and eval, but will need it back afterwards or you could buy it and send your OEM core back if you want it. Either way the spacer I will donate if you can document the before and after gains for the members here in general.

    I think it will all fit on the 2008 & 9, but am not 100% sure the port design is the same.

    Oh, I didn't realize you were the seller on that forum too...didn't even think to look. I would buy one today if I knew it fit!

    I'm looking into access to a Dyno and would love to test these for the fellow members....
    I guess 3 runs would be easiest... stock, + spacer, + spacer + tb. I guess we can do stock +tb too.

    Let me confirm that my shop has an AWD dyno, since I have a CTS-4.

    I appreciate the offer, and I'm very interested to see what we can do, combined with the Trifecta remap.
