I'd do it if I had a setup, looks to be good parts inside, teflon will take +200 deg easy. At work we use cal. discharge blower relief valves like that, they work w +180 deg discharge temps. Pretty simple imo, not much to go wrong, adj. a spring.
With something like this that old procharger f1 03 cobra setup might work w that bonnet and blowthru, at least build boost quicker to get the tq. on the street.
