    • 515 wheel horsepower modded '03 Cobra Mustang takes on a Weistec Stage I supercharged C63 AMG

      Here is a very good race video showing two runs from a dig featuring a Weistec supercharged C63 AMG and a modified 2003 Mutang Cobra. The Cobra has a ported blower and is putting out 515 wheel horsepower. The C63 AMG has the Stage I Weistec Supercharger kit with a full exhaust. It may be the Stage I or Stage I+ so in the 500-530 wheel horsepower range, possibly more thanks to the full exhaust.

      In the first race the C63 appears to hit its rev limiter and is forced to catch up which it impressively does. The second race is clean with the C63 walking away. A very impressive showing by the Wesitec supercharged car versus stout competition from a stop.

        Thats exactly why I jumped to the Vette... The Termi doesnt have top end legs and extended top end pulls make motors go BOOM. The stock HEATon (yes thats spelled correctly) is worthless for serious power. You need a built short block with cams & a big Whipple to play top end games with that car. AMG is nice the exhuast on those sound great

        Is it me or these SC'd Benz have bad noise? It's a luxury car (relatively). Keep it classy. That whine noise is great in an American muscle. Not in a Mercedes.

        It has power though. Lots of it.

        have you heard them in person Sorena? they are loud as $#@!. even without the blower, lol. even on a stock car, putting an aftermarket exhaust makes it sound similar, very deep and growling rasp. as for the whine, i kind of like to hear my forced induction at work Click here to enlarge

        I was referring to the twin screw whine. I'm very OK with hearing BOV's or whoosh or sc sound from BMW's because the majority of modded BMW owners are punks. No offense to real gentlemen like you or others whatsoever. This as a result, downgraded the image of BMW.
        But this is not true for MB's. You see much less modded MB's, and even those are not as bad as BMW's.

        As for the exhaust note, i would agree with your prespective 10 years ago. But nowadays things have changed. A Bentley CGT is a loud car. You can hear Maserati's and Astons coming from miles away. And all of them are more luxurious brands with higher prestige than Mercedes. It seems like quieter doesn't mean more luxurious anymore, it's the opposite.

        But when was the last time you heard a car pulling with a screaming positive displacement supercharger? For me it was days ago and the car was a Mustang GT500. I like that car, i really do, but it's not as classy as a Mercedes at all. Most of the cars rocking the same setup with the same whine place in that category as the GT500.

        Got my point?

        That's an exception. Definitely SC'd Cadillacs are classes above the most of cars sporting a screaming supercharger.

        I love the whine. But i don't find it suitable for a Mercedes. TS will give you instant throttle response that centrifugal and turbo can't even get close to. true.

        IDK. Maybe it's just me though. My famous classy this and classy that, sometimes annoy the hell out of people. Maybe it's one of those times that i'm too touchy about stuff.

        Sorena, I have the Weistec 3.0 blower. It is a direct drive off the serpentine so there is no whine. I personally do not like the whining sound for a mercedes so this is a perfect set up.

        Great race, that Merc really puts in work. I'm with sorena, not a fan of the whine on a Merc.

        i personally love the whine of a blower , no matter what vehicle it's on . the way i see it , if you are looking to buy a Mercedes for the luxury side of it , who is looking at the C-class ? most people would buy an E , S , or CLS for luxury . i think the C , SLK and SLS are closer to the sportscar category .

        Other than curb appeal, blower whine was my favorite aspect of both my past Jaguar XJR's. Luxurious and elegant, yet fierce when it needs to be Click here to enlarge
