• Renntech tuned SL65 AMG Black Series with 651 wheel horsepower takes on a bolt on Nissan GTR.. and loses?

      Here is a race that has caused some confusion on the boards and rightfully so. We have a Renntech tuned SL65 Black Series that is putting out 651 horsepower to the wheels. The GTR is believed to have 551 wheel horsepower from bolt on's with an AMS intake, exhaust, and tune. The Nissan GTR is essentially said to have an AMS Alpha-6 package which is capable of propelling it to a 10.6@130 in the 1/4 mile.

      The SL65 Black Series in stock form runs a mid 11 second 1/4 mile in the 125-126 mile per hour range. The GTR is lighter but not but all that much lighter with the SL65 Black Series coming in at the mid 4300 pound mark. It is also rear wheel drive with more horsepower and torque through the curve. It does not have the quick shifting dual clutch transmission of the GTR or the tight gearing down low. However, that does not explain how the GTR runs away at higher speeds where the V12's power should take over.

      The only logical conclusion is that the GTR has more than we are being told. A disparity of 100 wheel horsepower at higher speeds where the tight gearing down low is not paying the same dividends simply should favor the SL65. Yet we see the GTR increase the gap up top. Video descriptions without dyno graphs or mod lists to back them are very difficult to take seriously with these types of results and we always encourage users to question what they see when the claimed numbers do not add up.

      A stock SL65 AMG Black Series will dyno 560-570 wheel horsepower. With another 80 wheel it should be capable of at the very least matching the GTR trap speeds with the Alpha 6 package and realistically should pull it up top. Come to your own conclusion.

        Do not forget that that SL65 has 651 rwhp on a dynojet, while the GT-R has 551 on a mustang dyno. Add to that the weight of the driver ( no insults it's a fact ) and his passenger ( camera man ) + SL weight vs the GT-R weight with no passenger only the driver. Click here to enlarge

        it's freakin' youtube people . obviously there are plenty of half truths on youtube so unless the owners of the cars are here to discuss , just watch the race and the results and move on to the next video Click here to enlarge

        Frankly speaking being a RENNtech Bench flashed owner the GTR's are AWESOME cars and believe me they can run. Although the MB had two persons albeit the driver counted for two LOL and the passenger the GTR only had one person that can be misconstrued anyway you want it. We as in RENNtech owners got spanked!!

        those hp numbers should be taken with a grain of salt... from what i've read here... different dynos... probably different days...

        it's just a youtube video... they should have just listed the mods for each car and that's it... modded gtr vs modded sl65... and done...

        i find it funny that the description has the whp for both cars... yet in the video it has 805hp vs 551whp... which most people may miss with a quick glance...

        I can't help but feel someone wants to make it seem like their GTR is faster than it is by exaggerating the difference.

        You guys are also overlooking the differences in gearing between the two cars, in addition to the ~600lb difference in the cars the SL also has a five speed auto with really long gears compared to the GT-R's 6 speed dual clutch with tight gearing.

        We didn't ignore the gearing.
