That is of course less than the 753 wheel horsepower that was hit on a Dynomite dyno and it should show very clearly that different dynamometers read differently. There is no established standard but BimmerBoost does prefer Dynojet numbers as it is the most popular dyno. There are enough of them out there in the world that anyone should be able to find a local machine to use and we are glad BimmerBoost member @Ak335i did so.
So, while this does not exceed the 725 peak wheel horsepower number Vargas Turbo Technologies achieved with their Stage 3 turbocharger kit we are now to the point of splitting hairs as whomever is willing to push their motor (and transmission) further will have the record. This being an automatic car means it is far more difficult to upgrade the transmission and get it to hold the power. In that context this is a major development for the automatic N54 crowd and hopefully they have a transmission solution soon.
Now the question is, who will be the first to push past the 7XX range and who will end up raising the bar that is now a bit stagnant in the 7XX range? All BimmerBoost can say is when it happens our readers and members will be the first as always to know (and the ones who are raising it anyway).
