Welcome to the Tire Kickers channel! We're stoked to finally share what this BMW E39 is like to drive after spending 5 months in the garage being fitted with a new breathing apparatus. In case you missed the introduction video (link below), this car used to be a 2000 BMW 540i with the stock 4.4L V8 M62 engine before the drivetrain was completely re-engineered. The heart of the E39 is now the 6.2L V8 LS3 Chevy engine that can also be found in the 5th gen Camaro SS and C6 Corvette. The engine was previously naturally aspirated, but it now breathes through GM's LSA Supercharger. The most important part of this Supercharger system is the "Killer Chiller" that cools the intake air well below ambient and is incorporated into the A/C for more effective heat transfer. With cooler, denser air going into the engine, the car can add more fuel and therefore create more power. Proper performance of the "Killer Chiller" will be critical once the E85 tune is added, but for now we're sticking with 93 octane as we work out any kinks.

To say that we're THRILLED with the results is an understatement. The car absolutely sounds meaner and the Supercharger whine only adds to the mechanical symphony. The 6 Magnaflow mufflers allow the car to sound really aggressive without deafening you as you'll see in the video, and the exhaust burbles are sick. New tires are definitely in the cards because the car is struggling to find traction with all of the new power going to the rear wheels, but this should be a good opportunity for a proper burnout! We're also keeping an eye on the temperatures and pressures during these initial shakedown runs so we can identify and address problems before sending the car off to the tuner.

We have a TON of content planned for this car so definitely SUBSCRIBE so you can keep up with everything in store. Also, feel free to drop a comment down below if you have a question you'd like us to answer or have a video topic you want to see. Thanks for watching!
