Tapeing LG supercool radiator - F-Body Road Racing and Autocross Forums

Since this is about as low tech as it gets, I am putting it here. Absolute, if you think it needs moved, feel free.

I have had the abosulte hardest time trying to get my engine temps up high enough that I feel safe. The combo of the Mexiere EWP and the LG supercool radiator w/ a 180* stat I CAN NOT get my engine temps above 140*. Even on the dyno with NO fan running it never went above 140. If it did right after a pull it would drop like a hot rock right back to 140*.

I saw an older post by Lou on LS1tech saying that some of us would have to "tape" the radiator to get out engine temps up to a normal operating area. What did he mean by "tape". Did he mean litterally tape over part of the radiator? And if this is right, what would I use? Duct tape, 200mph tape? And if I do use tape wouldnt the heat off the radiator melt the stick'um off the tape? i was going to use a pice of cardboard to block about 1/4- 1/2 the radiator and thought of using tape to hold it on but was worried about melting the tape.

Can anyone help me out with this?

And if this is right, what would I use? Duct tape, 200mph tape? I think he meant 200mph tape right over the rad opening - preferably on the screen if you have one - not on the rad itself.
