    • Weistec McLaren 720S M840T V8 W.3 turbo upgrade dynos 957 rwhp on a Dynojet - 1100+ crank horsepower

      The 1000+ horsepower McLaren 720S era is exploding and Weistec has just what you need if you want big, big power out your 720S. Avid McLarenBoost and BoostAddict readers might be asking, wasn't there a dyno posted for the W.3 M8340T upgrade already?


      Yes, but that was on a Mustang dynamometer. It is important to highlight this fact. No matter how many times this website mentions it people will compare Dynojet figures to Mustang figure as if they are equivalent.

      For those who love Dynojet figures, here you are:


      957 horsepower to the wheels with 736 lb-ft of torque at the wheels. That power curve building to just past 8000 rpm is gorgeous and you will be hard pressed to find another car with a torque curve like that closing in on 1000 whp.

      Keep in mind the Weistec W.3 upgrade is a very reasonable $7999.99 as well: https://weistec.com/w-3-turbo-upgrade-m840t-series.html

      You definitely will want water-meth injection especially if you are in California and the supporting mods are listing on the dyno sheet.

      The McLaren 720S is simply stunning in the aftermarket.
