Zyborg your car runs hard, and I believe you when you say what you got done. I don't think your car is a "freak" I think it just runs the way it should and you got the driver mod.
As for your races with those Cobras, there are a lot of factors. First of all the heat, not sure if you guys are racing in like 90 degree heat but a Cobra will get heat soaked FAST after back to back runs. Second is the driver, and 3rd is the running condition of the Cobra. Stock clutch? Supporting mods? Cooling mods?
The ported cobra is mine, it was warm that day but not to bad. My mod list is in my sig. He's beaten alot of cobras, not just mine, hes got a video of a pullied one that he put bus lengths on!
