    • Weistec Engineering sets new quickest and fastest Mercedes-Benz AMG world record with a 9.1 @ 155 1/4 mile pass

      Congratulations are in order to Weistec Engineering for raising the bar and setting a new world record. The previous world's fastest Mercedes-Benz record also set by this same Weistec supercharged CLK63 AMG stood at 9.757 @ 151.95 which was set in November of last year at the ATCO dragstrip in New Jersey. In less favorable conditions at Byron Dragway in Illinois the same Weistec supercharged M156 built motor V8 W209 CLK63 AMG Black Series managed a 9.193 @ 155.11 pass with a 1.550 60 foot time good for a new quickest and fastest Mercedes world record.


      Density altitude at noon was 730 feet above sea level and the temperature was 55.9 degrees. Not the best conditions possible but certainly not terrible either. With zero to negative density altitude the car will run 8's as it sits and some power was dialed out to help the 315/50/16 Mickey Thompson drag radials hook off the line.

      A video and the timeslips are below. Please do not pay attention to the date on the slips it is incorrect. The passes took place on 5/17/2014 not the 5/19/2014 it states which at the time of this writing is actually tomorrow.

      The quickest pass comes on a 150 trap speed with a 9.160 elapsed time and the fastest trap speed is a 155.78 which comes on the worst 60 foot at 1.716. The most telling pass is the 9.193 @ 155.11 slip. An incredible 4.0 second flat 60-130 time was also achieved.

      Congratulations to all involved and at this point Weistec is only competing against themselves. It certainly looks like the first 8 second Mercedes street car will come from Weistec Engineering.

        I'm not sure what the bet is for but seeing how this has mostly been about the transmission, I will make a wager for you.

        I bet you that you cannot go quick (the times like you have already done) with the factory transmission that comes with your car. The transmission does not need to be stock, it needs to be a factory unit. I will bet you $500.00 that you can't do that, does that sound like a fair bet?

        That's fine let me know when it's back up mine should be ready to go by then. I don't know why it already isn't I have to make some calls.

        I don't think they have, no. I know they're pretty busy and not sitting on the forums.

        Butthurt= some MB members here. Very sensitive crowd. Maybe beat up as kids?

        As a newbie and a novice to AMG I'm going to keep my nose clean. This thread records an awesome achievement.

        As for the trans. I look at it this way. I'm no engineer but I know some clever ones - mechanical and electrical.

        Give me a MB Black Series transmission and a blank check and I'm CERTAIN I can find people who have never seen one to come up with a far stronger unit that could be shifted manually and mechanically whether via cable or linkage. I've seen Dodson do good stuff for GTRs.

        Its a gearbox and if electrical impulses can shift the damn thing so could custom made linkages. The factory ECU will need to be told a story it is willing to believe, but inside a factory looking casing, there could be a bold new world. Factory casing doesnt mean factory gears. There is IP in there that someone had to pay for.

        I'm confident of success if I had the money to throw at this, because I know what is possible. What I don't know is the cost or time involved starting from a clean slate and access to cad cam, and fully equipped engineering workshops with cnc etc. Maybe a year and $250k? Once I had the ecu and shifting worked out I'd certainly consider a market proven race shifter to adapt rather than waste money trying to make something unique.

        But Weistec Know these trans and have years experience. That gives them a big head start.

        If so, awesome, and when Weistec are ready to talk about it kudos for the effort.

        There will be an upper power limit to even billet gears with an over drive ratio. The lower gears are bigger and will take more. I'm going to go back to the corner now.

        Lol. I can see how some are here. I never accused anyone of anything. Just stated my opinion that from an engineering perspective it is possible to take a Mercedes trans casing and make the internals stronger and shift conventionally. Most got it, but someone negative repped. Hahaha, looks like we're going to have some fun on this site. But I'm done on this thread. Looking forward to seeing that first 8. That 9.1 is stella.
