Good Luck Rev!
My last trip to the strip I was accompanied by MystiqueSVT who recently purchased a WS6 vert auto T/A. He wound up running 13.5 at 105 with minor traction problems. His only mods were: "lid", and tb coolant bypass.
We had a slight "roll in" one could say on the back straight and from the 60-130 mph we were dead even. I was running 5psi at the time as usual as my car is pointless on anything more as wheelspin is a major issue.
My point is that anything is possible....A car not neccessarily made for drag racing running in the low 14's(that night) can be on par with a much faster car under certain conditions.
Fastest et to date is a 13.8 at 103 mph.
