They're interesting...but they have trouble going fast. Not that they lack power or potential...however it seems they have trouble putting the power down whenever I see them...especially if it's cool, especially if they're on street tires, especially if it's from a dead stop.
I've seen 4 of them at the dragstrip over the past 3 years
1. bone stock other than rear drag radials - ran high 12s @ 111-112 all day in good DA (around 0 feet)
2. modded (no idea what but LOUD!), drag radials - ran low 12s @ mid teens MPH in decent DA (around 1000 feet)
3. bone stock on street tires - this was the weirdest one. It was a cool day (50 fahrenheit/10 celsius), great density altitude (0 to +300 all day) and he couldn't even SNIFF the 12s. Mid to high 13s all day @ 110+mph.
Here's him vs. my bone stock 2008 Audi RS4
Here we go again...this time I blew the 3rd to 4th shift , but still won pretty easily.
