Anybody ever tried this little gizmo?

I wasn't speaking to NASCAR engines, since I know not much about that stuff (nothing) and there doing something completely different than a drag race engine
That's pretty much the point of My post. There's only one way to know for sure what works for Your combo, try it, put it on the track & work with it. It either flies or dies....
Or just do what somebody else has done that works, & accomplishes Your goals, and move on..
