Greetings 6 Speeders,
Thank you for all your questions and responses. Let me take a moment to clarify a few things since this has become such a hot topic and the plenums are such a new and unique product.
1. Installation time in about 30 minutes on your first install and probably half that during your second installation. The plenums on naturally aspirated applications install VERY easily and VERY quickly. We have installed over 40 plenums and have had only glowing results.
2. Many of the older dyno sheets from older webpages had earlier model plenums installed, some even prototypes. These product have gone through many design and manufacturing evolutions. The latest version is the one that is now available. It incorporates the equilization holes, epoxy coating and casting improvements.
3. All plenums "should" provide improved performance with any and all other mods. We haven't tested the plenum with any after market super chargers but the plenum allows for greater air flow so fundamentally it should enhance any forced induction system. Improved air flow is always a good thing whether it's stock or tuned.
I also know that a picture is worth a thousand words so hopefully this illustration will help simplify how the plenum improves and speeds air flow.
Again, we welcome any and all questions or thoughts on this subject. Please feel free to post, PM or contact us by phone. Thanks again for all the feedback and postings.
