Krambo Posted February 13, 2007 Report Share Posted February 13, 2007 any one have any et gains after they did headers... Brad Sure do. Way back when, I had a CAI, 160 Thermo and ran it at the track and did a 15.2XX. That week I did ASM headders, X-pipe, dual Flowmaster 40 series all in 2.5". I ran that weekend and improved to a 14.8 under the relatively same weather conditions. After a cam, 3000 stall and lots of tuning, that set-up did a high 13.

thomp62301 Posted February 13, 2007 Report Share Posted February 13, 2007 with my mods i dropped from a 13.2 to a 12.6 just by installing the dynatech header kit and a shift kit. Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted February 14, 2007 Report Share Posted February 14, 2007 (edited) son!, guess i should've done headers. I could get a whole asm set up, bolt right on for like 700 used, but i kind of like the supermax. Looks like they both get great et gains. I've got my TEA heads and cam breathing through stock manifolds and cats right now, so i would think the headers might even show a better et drop for me. I think restalling my PI converter is next though. Thanks much guys! Brad edit: Krambo, just looked closer at your sig. Do you have the 9.5" vig or the 10.5"? I have the 10.5 and the thing is tight as hell, stalls at like 22-2400, so i'm thinking of pulling it and getting the 9.5", but chuck (flt) doesn't recommend them for the weight of our trucks. Here is quote from the PI guy I'm working with "We don't have a max vehicle weight per say on making a converter selection, we look at the whole picture. Of course getting into the 5k to 5500k range is pushing it." Edited February 14, 2007 by shadowsniper3006 (see edit history) Quote Link to comment Share on other sites More sharing options...
