Transmission shield or tunnel cover
I would and I do run a blanket. It does not make the trans run hotter. I have been drag racing over 25 years and everyone I know runs a blanket. The shields are a pain in the ***. You do not need a bell housing shield til you run in the 9's. You can also buy a billet drum for the trans that won't come apart. Where you are likely to have a drum explosion would be launching in 1st gear and breaking a ujoint, drivshaft or rearend, that in turn will make the sprag in the trans break and the drum in the trans will spin backwards 3 times the speed of the engine RPM and then the critical speed hits and the drum comes apart leaving parts everywhere. So make sure your ujoints, driveshaft and rearend are in great condition before you race.
