They work on street engines, I’ve never had the few I’ve used over the years pop out but at the drag strip on a high 10 second car is it? No way in hell would I take the chance regardless of how many say otherwise, how many runs you planning?? envision being the guy that has one pop out, rpm’s at what? 6500+/-?? at a buck and a quarter at the top end at the track?

Street? Absolutely. Track? Yes, dumb.
