Dave,
Another apple! Do you have pictures of your cross over pipe? I'd love to see that installation. Any chance you dyno'd before and after?
Tell us more please!
(edit ->) CobraEd...I think you are absolutely right! The problem is of course the room available to work with. I'm talking "street use" and your talking "optimum use". With us, building an exhaust system is little more than guessing, I don't have a Dyno to use for testing purposes and the time it would take is absolutely prohibitive. It takes me a full 50 hour week just to build one set of headers for our DV's.
I actually entertained the idea of trying to build equeal lenght type headers for the DV II just to see how much HP would be gained. Roughly three hours later, I trashed what I had and simply gave up.
We're contracting for an entire new type vehicle with a very, very special engine. If this comes to be, I'm going to be knocking on your door along with ERP's. ( I still think he is not letting us in on all his knowledge!
)
