A relatively new i8 owner question
Hi All
I recently moved to an i8 from M4 and so far loving it. I'm pretty technical and curious about everything. One thing I had not cracked is where is the air scoop for the twin turbo buried in the back over the rear axle? Is the aerodynamic cavity from the bottom or the side feeding into an intake? If so, how low is it and how susceptible is it to suck water and get hydrolock scenario? Thx for the responses.

Single Twin power does not mean Twin Turbo

That poor three 500cc cylinders are working hard. Of course, I could be wrong.

This should clear things up: http://s3.bimmerfile.com.s3.amazonaw...B58_Engine.pdf
It describes the B58 engine, but also shows that except for number of cylinders, the engine technology is the same as for the B38, which we have in our i8s. "TwinPower" is used for any setup that includes a number of performance and efficiency enhancing modules, incl. variable valve control and turbo charging. The turbocharging technology used in Bx8 engines is a twin scroll setup, with two differently shaped fans on the exhaust side driving the same spindle. According to this document (p. 50), all Bx8 engines have a single turbo unit. |
