The only issue I had was the smaller idler pulley that came with the kit gave way (along with the OEM belt) around 5K miles after the install.
I re-installed the larger OEM idler pulley and went with a larger Gates Belt and I've never had a problem since. (45K miles)
I don't race but my car has been subjected to the Texas Mile, high speed desert runs (+160 mph) and hard core canyon runs (hard on the gas / hard on the brakes).
I think the 185 is great for highway driving as it gives a huge shot of instant boost to blow by cars and have some fun in the curves.
Can't rate it for the 1/4 mile racing.
Running a Texas mile is no worse than running several 1/4 mi runs. But I can assure you unless you have one of those motors I mentioned, it will run lien on a sustained run. How many runs? Only time will tell. But I bet you don't run like that everyday or for long distances. If I am wrong, then you are lucky. The motors are built well, but they are all a little different. More fuel solved my lien issues. A tune can solve them as well, so yours may be tuned to the rich side. The fine line is tuning to run right at the line between lien and rich...and that line is hard to find without a great tuner.
