I can't say I haven't seen slower cars hurt engines and cause oil downs, but most of the problems I remember seeing at those speeds have been trans blowups, not engine damage. You can add my vote to Overkill! opinion.

If my local tracks do start requiring this for 11.99 and quicker cars, how difficult is it to install one on a B-body street car with tight fitting (tti) headers, a full exhaust, but no power steering? I use a Street Hemi pan, so would I need a custom made diaper to fit the pan? It already looks kind of cramped under there to me.
