This next video shot at Spring Mountain Motorsports Ranch comes from Smoking Tire and presents a Porsche 911 and a BMW M3 (both turbocharged by VF Engineering) driven on track by Matt Farah.
Besides the upgraded headers and a blower added to the engine the rest on this Porsche 911 that can now produce 510 HP is stock, while the 620 HP BMW M3 features a wide-body conversion done by Vorsteiner.
The VF Engineering BMW M3 comes with a custom made intake manifold that enables it to hit mind blowing speeds, and even though that exterior treatment might look a little bizarre, the engine noise is quite impressive.
Watch the VF Engineering BMW M3 video after the jump.
