330e's Xtraboost on dyno

Hi, this is my first post on the forum after been stalking for quite a while.

Just wondering has anyone put 330e on the dyno test and see the different in the result when the Xtraboost kicks in? I've ran many rounds on various factor, but I cannot see any effect from Xtraboost function.

In any modes (Comfort/Sport/Sport-Xtraboost), I've got almost identical results except slight 1% variance from all of them. I tested on 4-wheels dyno, dyno test mode enable, sport manual gear shift, full throttle kicked down. Not sure what's the actual trigger to call out that Xtraboost?

Anyone has a comparison graph or advise regarding this Xtraboost function?

Thanks for sharing, cheers!

Totally stock my 330e with b48b20B on gas 99oct RON (50%/50% 98/100oct)



So i think good result

325hp 465nm only on good quality gas

What is your final result?

Is that HP measure at engine or wheel? Mine is 280 HP (322 engine HP) for stock run and 328 HP (377 engine HP) with the box.

Back to my original question, by any chance you test in the normal mode vs Xtraboost mode. I keen to know if there's a comparison graph as no matter what I tried, I cannot see the different on the graph (with and without Xtraboost).

What tuning box are you using?

And also, I hope someone with a G20 330e can provide some dragy numbers for a stock car. The only run I've seen is from Mazman and his car didn't seem significantly faster than a 330i for a car that puts out 325hp stock!
This is exactly why I'm more into dragy/drag strip numbers than dyno numbers.

would be interesting to see a stock 330i on the dyno as well.
I guess it will also be underrated as BMW's usually are. Also important to keep in mind the 330e Sedan is 300kg heavier than the 330i which will eat up most of that advantage before the car is up to speed.

On the 330e I wonder if one can trick the car similar to GOLF GTE/Seat Leon hybrid and a like. Those cars also have the same setup with an extra HP function for shorter period however on those cars its seems if you briefly let go of the accelerator and get on it again you get another 5-10 seconds of x-boost which gives some 10th's
I unforunately did not try this on my car. Maybe I have to get a loaner and try this out
