BMW upgrade of N54 turbo six!
It has been made official: BMW Performance will be offering a performance upgrade for the N54 twin turbo six! The engine software and components that gave the new 740i an increase in horsepower and torque will essentially now be available as a dealer installed option for 135i and 335i models.
The BMW Performance Power Kit consists of both software and hardware components including additional water cooling. The kit will be installed and covered under warranty by BMW. In European terms this gives the engine 20 more horsepower (326 from 306) and 50 more Newton meters (450 from 400). In the US that should figure to somewhere in the 321 hp and 336 ft/lbs neighborhood. The performance increase is noted as .2 of a second from a standstill to .5 seconds faster in the passing range.
Official US information has not been released but we have heard for some months that this was in the works and that we could expect something at dealers in April. We will update you as we hear more so as always stay tuned!

Hmm...what does it all mean!?!? Its all but common knowledge that the N54 motor from BMW isnt putting out 300hp/300lb tq. Its more like 330hp at the crank. So does this bump it to about 360ish? We will see. BMW is super conservative with their acceleration times on the corporate website.

Only 20hp? GM gives 30hp with the new tune for the Solstice/Sly, and probably costs a lot less.
