7/8" stretches on hard launches, ask if the V8's do as well. Heck, you were there when I noticed the last 7/8" stretch and again reluctor was torn off. It comes down to normal driving. The V8 chains are very good and hold a lot of power, Dave would be the one to know best on if 7/8" are stronger than V8 etc.
You can destroy either chain setup by driving the way I did. Look at the way Dan and Nick drive.. sure seems the rolling race is a lot easier on the chains. A few track passes shouldn't hurt either chain setup though.
