X5 50i with Dinan Stage 2 tune, 13.159 @ 104.16
I took the X5 to Raceway Park today. It ran consistent 13.23s until the first round of eliminations. I ran a 13.159 @ 104.16.
The truck seems to need a little time to build boost. On the last run, I was powerbraking the truck for about 3-5 seconds more. My best MPH was 104.46. The truck weighed 5190 with me in it. Based on the MPH and weight, it is making roughly 485HP at the wheels. I know Dinan is not the most agressive tune; but, they definitely meet their claim of 501HP on the Stage 2 tune. |

Nice numbers. I have a stage 1 and I ran door to door with a new S5 off the line without brake boosting up till about 100 when he had to let off to merge behind me, and also ran side by side with a Mustang 5.0 from 40-100. I also absolutely embarrassed a new GS350 that was trying to mess with me on a freeway onramp.
It's definitely quick, especially when you use manual and make sure you are in the right gear. With brake boosting off the line you can very closely approximate the launch of the X5M. I think it should be capable of high 12s at around 108 with the right launch and good conditions.
