Can I get some before and after Dyno #'s from people who particiapted in the first GB.
In your list please include whether its a 98 SVT UIM, 99+ SVT UIM, or a standard UIM and what your Mod list is.
Anybody measure with a micrometer what the before and after opening were? Please tell if its a 98 SVT UIM, 99+ SVT UIM, or a standard UIM.
Do a search for "EH UIM" and "Extrude Hone" in Group Buy and Duratech Performance, all that you ask about has been posted...I even posted my personal Dyno results with a list of my mods, type of dyno and before and after dyno numbers. This was just posted again a few days ago in the Extrude Hone interest thread. Measurments were also taken on three SVT manifolds after Extrude Hone was done to show the conistancy between all three. The gains in port size was also noted on all 3.
