I know all cars seem to be a little different but I had to really beat the floor for clearance to get my CSI shield on a 904. My exhaust is super close to the pan ran and I can't see how a blanket would have worked well for me. My shield came with the mentioned 12 point bolts. I cut holes in the firewall to access them with a socket. I should have done that long before the shield, it sure shaves some time off a transmission removal.I run a blanket, or used to. 904 now, just personal opinion, but I believe a blanket would control an explosion better. I have seen pictures of holes through a shield. Just my gut feeling.
With the shield, I have never got my trans hotter than 210 and that is after 9 rounds of racing and on the return road where the trans will build most of its heat after the run. Goin down the track it’s never been over 180-190Did any of you guys notice a temperature increase with either the blanket or shield?
