Uh Bikecop, I think we are going to get are a$$es handed to us by these E55's. I really didn't know what kind of HP the E55 put out, so I done a little looking. A 2005 E55 is rated at 469 HP stock, witch might be a close race with a modded SRT 6 with the weight difference. But a modded E55, that might be a different story. I just watched a video of an E55 with a stage 1 RENNtech upgrade and he done an 11.666 @ 120.410. I'm pretty sure if these E55 guy's do some drag racing, they will most likely have a few mod's. But an 11.666 shouldn't be a real bad spanking for us, but it's still loosing .
