patrickt Pat the old line been there, done that, and done it the hard way. I have covered it all. If you are running a mini multi disc clutch, this bell housing "may" protect and hold up fine. A full size 40 lb fly wheel clutch assembly is another thing. QT is tested but not certified, WHY?
They sell 2 bellhousing for the FE motor, one says nothing in the info about SFI testing at all. The other says has SFI testing. Did not say if it passed or failed. There is a 99% chance that these guys will never race or spin there motors 7,500 rpm and have a flywheel schatter. Again 95% of the guys are running SFI flywheels. I don't want holes in my bellhousing. I want everything to stay in the tub. I blew 1 clutch disc and it came through and crack the stock bellhousing,(aluminium) after this everything I have is lakewood. $400.00 dollars with worth walking and running on my own to feet. They sell shields for auto transmissions and blankets for racing. I have seen a 200R-4 explode and the blanket saved the driver's legs. There are lucky people and people without, I am the later, but have learned that by buying the best parts on the market for racing have limited the chance if injury to myself. Everything on my car is SFI CERTIFIED, I have no interest in tested Rick L.
