On Sunday, January 20th, my E63 S with Renntech full tune and Renntech sport mufflers (stock cats and stock downpipes and stock turbos) competed in roll races at Race Warz 2 at Pocono International Speedway. All of the roll races in the videos below had a 60 mph start.

Overall, I was happy with the results. It was faster than tune only cars but not as fast as cars with catless downpipes or water meth injection.

The wins:

1. Dodge Charger Hellcat. Lost badly to my car (4 car lengths):


2. E63 S AMG sedan with catless downpipes and custom tune (2 car lengths):


3. AMG GTS (stock) (1-2 car lengths):


4. Dodge Viper (1 car length) -- 2 wins:


5. Cadillac CTS V (modded) (4 car lengths);



6. E39 M5 (6 car lengths):


7. 911 Carrera S (many car lengths after giving it a head start):


8. and 9. Other wins not videoed: 997 Turbo S (from a roll) and Lexus RC F (from a dig)

Losses:

1. 800 bhp water-meth injection, catless downpipes, custom tune, aftermarket intake F10 M5 (23 lbs of boost) (fastest F10 M5 in the New York area) (many many car lengths):


2. JB4, heavily modified M6 with 21 pounds of boost (2-3 car lengths):


3. Cobb Stage 2 tuned 991 Turbo S (3 car lengths)


4. SLS with all Renntech mods including tune and straight pipes (3-4 car lengths):


Other losses not videoed:

5. E63 S with Renntech VIP tune and catless downpipes (5-6 car lengths)

6. Modded SL55 (I had mine in manual mode and missed a shift)
