03 Cobra vs Mercedes Benz CL-600 friging v12

I got myself into a race coming up in a few weeks with a mercedes, didn't think to much of it untill I found out it has a V-12 in it!! My car has all the standard bolt-ons and runs pretty good IMO. It's best was a 118mph 11.88 et, on a very cool evening with track prep right on. But I haven't been able to match that , with my best the last few times out being in the 12 0's . I really want to beat this car....badly. Any ideas or something I can try before the race comes up? Oh , I'll be running on a set of pretty used Nittos, getting slick , that should help right? My 60ft has been as low as 176 , but average around 188, leaving on about 3500 rpms and just dumping the clutch usually spinning a little in first with hardly no spin , maybe just a chirp in second. Help me out , don't want to lose to a big ol barge that weighs about 1000 more lbs. than me. Mine weighs in at 3860...his at 4735. Don't know what if any mods he has..says it runs hi 11's low 12's.

I'm hoping he shows up on street tires. Don't know if he has any mods. Haven't talked with him yet, race was a set-up type deal thru some guys putting on a bunch of match races at the local track. Only seen one of these type cars around in our area, driven by a young guy, hope its him, maybe he don't know anything, or at least less than me, about racing at a track. Taking place on the 18th , I'll keep you informed on outcome.

All I know is what he posted up , called it a Benz CL-600 Turbo V-12. The Turbo part has me skeered!! When I find out more I'll pass it on.

I asked this ? in the Tech forum but thought I'd throw it on here also. Anyone put ice on the blower between rounds. Pro's & con's. Help et any?

Here's the results

Let me say from the git go, he was a nice fella, not cocky or a smart a. The car is beautiful , and it runs great. I started off from the house by setting my clutch up a little tight using the firewall adjuster, I like the pedal to be a little stiff. I'm not making excuses , but that cost me the race I believe. My first pass I smoked the clutch pretty much all the way down the track, I felt it and pedaled it thinkin I might clear it up. But when I got my slip I really new it was bad. Ran 12.86 at 111mph. Now I'm tryin to cool it down and get ready for the match race, it's a set time to line up. I back the clutch adjuster back out to almost where I started from and get in line hoping for the best. Oh yeah, that first pass 60' was a 1.93. We stage and leave about even but not for long. He pulls about 3 lenghts on me at around the 330 and we stay that way thru the traps. My time was12.51 at 112 mph. He didn't show his time and they split the slip so all I got was my side. If 1 length equals a tenth then he probably ran a 12.20's. I can run better than that, and I want some more, so I'm looking for him back in the pits and we find each other and before I can get it rematched he's saying he's got to go. He had his kid with him and another kid, his son's friend and something was up , they had to go. Didn't know what to think of this at this time. But, I've talked with him since and he's up for another round so to be continued. He was running some BFG drag radials and he told me that all he had done to the car was a chip tune. Said that's all they offer for the car, no aftermarket anything. Oh, my 60' on that pass was a 1.92 , still not good. I ended up running 2 more times that night with my 60's being 1.94 and 1.96 with my mph being way down , both being in the 111's , with my past runs being in the 117's and 18's. Just a bad night for me all around. I should have left things alone and just run the clutch the way it was, but this clutch has about 1900 miles on it since I changed it out and usually run with the pedal having some slack in the top , thought I wasa helping it by taking some of that slack out. OL well , live and learn. Sorry I didn't defend the American Muscle Car the way I should have......But I did outrun a 240 Z car with a sbc 350 in it. Don't know the particulars on it but it had uncapped headers hanging under it. Thanks everyone for the advice and support. I know I'm gonna get flamed , so let'er start.
