Not doubting ur word, but ur having more trouble than I do, and I can only run a 17" mechanical fan. I`m still experimenting tho. If I ran a larger fan, it would hang out the top and bottom more, and maybe the pass. side too.
I`m currently having a 1" ring heli-arced on the shroud to almost cover the fan to the rear.
Will be interesting/I`m going to drive it to mens prayer breakfast this morning w/ no shroud, bet it cools real well on the hiway.
