Most if not all X275 are 1/8th mile. The nitrous cars can keep up with the turbo cars if not do better.

In fact I get a daily report from the last 2 weeks of X275 racing from my co-worker that keeps up with that class and he's telling me that Nitrous is taking the wins and the Records.

4.7's in the 1/8th best I have heard him mention so far the last 2 weeks.
