    Weistec M156 3.0L Stage 3 Supercharger Upgrade. Photos, Dyno, Vbox Record

    My Brother @Jacob502 asked me to post this for him.We wanted to do this write up a while back. We recently upgraded our M156 SL63 to the newly developed stage 3 Weistec SC kit. We also got the 722.9 bullet proof transmission and valve body upgrade along with the trunk ice tank.


    Photos of the MCT transmission being removed before sending it to Weistec:

    Here are some photos of the 3.0L system being installed:

    The upgrade was completed around mid January. We tested the car on the Vbox and it went 6.86s from 60-130mph. World's Quickest VBOX Record for A Mercedes SL class from 60-130 . the record is on dragtimes on the following link
    http://www.dragtimes.com/Mercedes-Be...lip-25207.html
    (They somehow uploaded our previous dyno run with the 2.3 and thought it was the stage 3 dynosheet..lool)


    During that time, the car was misfirng at cold starts. We took it to the dyno and it made 630whp/580wtq. The AFR was around 9.5-10. We later found out that the SC wasnt installed properly and it was causing Vacuum leaks. We later installed it properly and the misfiring at cold starts thankfully disappeared. The Supercharger was fitted correctly with no leaks

    Luckily for us, Steve, Director of operations at Weistec, was in the Middle-East working on a few cars in the UAE. He was kind enough to fly out to us in Qatar to custom tune our SL63. A true gentleman who knows what he is doing. He came with all the tuning tools necessary and was commanding AFR and ignition timing changes at the dyno. We are very thankful that he helped us out. He gave us a few tips as well:y. Thank you Steve


    This is Steven making map changes on the dyno. He made the AFR stable between 11.5-11.8






    Last dyno runs resulted at 671rwhp/617rwtq, here is the dyno sheet:

    Car is absolutely a beast. I am more than confident that we will tap a quicker Vbox record than the 6.86 we posted. It is pulling speed quicker and harder right now. We want to take it to the drag next winter, as it is getting hot now. Hopefully the results will be excellent. This beast is really FAST:zoom:. It literally spanks my SLS right now. It also looks absolutely stunningClick here to enlarge.

    Again, Thank you Steve for giving birth to this Weistec Stage 3 Beast in Qatar.:zoom:

    You pulled the MCT transmission and replaced it with the 722.9 torque converted transmission ? Doesn't make sense.

    Where did we mention we added the torque converter?
    Really shows your level of understanding Click here to enlarge

    For the record guys, the MCT doesn't come with a torque converter from factory. It is replaced with a wet startup clutch

    The torque converter from Weistec is also optional on TC cars, like the C63, @Sirex63 also had the bullet proof upgrade without the TC from Weistec


    The transmission upgrade consists of hardened internals, upgraded clutch packs, upgraded discs, upgraded Shaft and maximizing the surface area of the transmission, which is on our SL63 RETAINING THE WET CLUTCH

    The Mercedes 722.9 is the automatic torque converted transmission. What you should have said is that Weistec BUILT your existing MCT gearbox the same way they do the 722.9. Thanks for showing YOUR level of understand. LOL

    Yupp the MCT is the 722.9 same trans just using the wet startup clutch instead of a torque converter like you already mentioned hehe How does the car drive with the new built trans? Are the WOT shifts the same or crisper? How about daily driving at part throttle has it added any jerkiness

    Transmission is smooth really smooth. WOT Shifts are quicker. Daily driving, its like you did not upgrade it at all. Nothing is changed in drivability.

    when kicking it hard, I have founf that in modes S or S+ the tranny shifts either a little early or hits the rev limitier. It is better if I switch to manual mode

    Just wanted to share what we use for our Ice Tank. We have found that Prestone Antifreeze (RED) is so far the best coolant to use for the Ice Tank. right now in the Middle-East Temps are between 95-100. On our OBD, IAT's dont go above 39C ~102F on normal driving and they dont go above 45C~113F on WOT.

    It really work good with us in the Middl-East. I am sure it will even work better in the USA.


    You can buy it from Amazon, they offer it in a six-pack. The Ice tank needs about 3.

    The 671rwhp/617rwtq Pull was done using Prestone Red

    It has some Anti-Corrosive Materials in a higher concentration. It also contains some concentrated additives that help prevent heat. There is the Prestone Blue and the Prestone Green. I tried them all. The Red seems to work the best and helps in reducing IAT's

    Great post guys, @Weistec are improving themselves more and more. This SL63 happens to be the most powerful in its category in the Gulf and the Middle East hemisphere. We're just waiting for the the best weather over here ( UAE or Qatar ) to take it to the drag strip.

    Congrats @Jacob502.

    A bit off topic. We got a idea of the C, CLK and Sl's but what about SLS Weistec. Are there any racing around in the ME? Are they only 2.3L or are they fitting 3.0?

    Yes there is. There are two, one with a 2.3L and one with a built motor 3.0L that is making 800+ at the wheels. Weistec worked on this SLS when they were here.

    My Brother's SLS will also be boosted . We were going to put 3.0L setup last winter.We are just waiting for Weistec to officially release thier new productsClick here to enlarge.
