I did mine more fer seeing what aerodynamic improvements a grill block would accomplish and still provide enough air fer cooling requirements. So you will have to experiment on what yer goals will be fer yer grill block.
I found that zipties or velcro ties worked the best to secure the pipe insulation to the grill once I inserted a PVC pipe inside the insulation. I tried zipties fer durability or velcro ties fer easy removal. I did experiment with a locking cam setup behind the pipe but it was too complicated fer easy removal.
I did install a digital thermometer probe under the hood just so I could keep an eye on what was happening under the hood. Obviously...the probe placement is key so I placed mine between the top of the air plenum and hood. I've seen a range from 30°F to 80°F above ambient while driving distances over 50 miles. Fer warm up times, I can't really say it's decreased the warm up times as I really haven't paid attention/experimented with the grill blocks on or off during the colder months.
The key is to establish a baseline and then see what yer mods will do. If you establish a baseline with yer mods and then take them off...you might be able to extract what the mods did. It will depend on yer data collection and how diligent you are on yer data details.
