I will say as I have before, a “non certed” steel housing (like the Quicktime) will most likely provide better protection than a cast iron or aluminum housing.
Just remember there is a large difference between a SFI certified bellhousing and those that are not.
If anyone here has information, data or photos of SFI Certified housings failing to contain an explosion, Id love to see them and discuss it.
