I absolutely love that this car runs 11's with a literal boost plug in. Gonna spend some time stock but I'm sure a jb4 is in my future.

The jb+ is attractive just for ease of install and removal

Yes Ian.....for an non-M car they are impressive. Dyno man reckoned a JB4 could add another 15-20BHP over the JB+ if set up correctly and on premium petrol.

I ran my 2024 M240I xdrive on Dinans dyno in Opelika AL. and hit 405/439 wheel. Translates to 465/504 at crank with 15% loss for drivetrain.

405/0.85 = 476

516tq

In theory if 15% dt loss is real

What are the mods on your car? I see dinan exhaust.

Looks good in the colour grey.

The B58 is certainly easy to tune without spending too much money.

What dyno is that?

The dyno is at APR/Dinan facility in Opelika Alabama. My wife and I went for our anniversary to the Haus Party on October 12th.
Had a blast, met some cool people, toured the facility and learned how they take a 3d scan of vehicles to create performance parts they then test. I am in engineering and was impressed. 3d printers to full production of CNC machining parts. They also hand weld the exhaust systems in a jig. Very cool experience!

M2 Whp

Every 2024 M2 that I have seen tested on a dyno here in the US is pulling between 469-471 hp at the rear wheels (Whp). BMW claims 453 at the crank. They are notorious for underrating their cars.

Some tasty cars there with some nice lumps under the bonnet.

An impressive facility from the look of it.
