    • What happens when an ESS-Tuning VT3-700 supercharged built S65 motor DCT E92 M3 runs into a stock internal M156 Weistec Stage III supercharged C63? It loses

      This was a race many of you were waiting to see, a "built" motor supercharged DCT M3 versus a Stage III supercharged C63 AMG. The C63 AMG is the new W204 Black Series whose M156 V8 features stronger forged internals than the standard M156 in regular C63 AMG's that do not have the optional P31 performance package. At about 11 psi of boost on a 91 octane tune for the AMG power is in the upper 600 wheel horsepower range and would be higher with a race gas tune.


      The E92 M3 features an ESS Tuning VT3 built motor setup with power in the mid 600 wheel range on race gas. Unfortunately, this is a very weak example of a built motor M3 due to the block not being sleeved. It is simply a stock block with a dropped compression ratio for longevity purposes which prevents "accidents" from happening on the stock internals. It really does not offer much of a power benefit over a stock internal car as the compression ratio drop means more air needs to be compressed to make up for the lost power per psi of boost.

      It uses the exact same Vortech blower as the standard ESS kits which is undersized for a true built motor setup. A properly built low compression M3 with a properly sized blower should not lose to a stock internal M156 on a 91 octane and should not be in the 6XX wheel horsepower range. Regardless, what happened is what happened and the Weistec Stage III setups continue to impress as this C63 beats "the best" ESS has to offer and has been seen simply walking away from some very quick cars. Much respect to Wesitec on their build and checking egos, video below.

        Directly posted by JRcart I don't think he has any reason to make that up

        I will say this.. last year with the sweep was actually better for those with manuals then the short staging area we got this year. For us with M3's and short gears we could barely get to 40 before the cones, so no time to brake boost, and a lot of awkward gas brake gas brake trying to line up.. probably fine for american cars or dct cars but for us rowing gears with short gears.. it was tough.

The c63 BS made ~660whp with a medium pulley and a pump tune and was later revealed the 660whp was a sand bagged number so add in a big dog pulley and 109 race tune id think you'd be right there with the Vargas Car and with MUCH more power under the curve your only getting 725 from the vargas for a small rpm sample so a dig race would favor the twin screws instant off idle torque
        Good points...

        the run where i ran off the runway me and kevin went in 3rd and i didn't brake boost and my car felt boggy. in second it seemed to stay in the power better but its so fíng short!
