Sounds like your under tray is working, at least to keep your temps up. I think we got a team going here. You try some mods, I'll try others. That way we can eliminate the bad ones and find the good ones faster
I wouldn't go any hotter than 225, it can take more, but you risk getting hot spots that could cause trouble. You gotta realllly over heat it to warp the head. I would try this under tray on my car right now, but without the scangauge, I don't want to take a chance. So I'm relying on you to gather data
Here's a couple pics of the begining of the manual shifter. The four switchs are, the 4PST switch is to switch from auto to manual, the 3PDT is 1st to 2nd, the DPDT is 2nd to 3rd, the SPDT is 3rd to 4th. The extra switch pictured is for the Torque converter lock up, which I am not hooking up yet, one thing at a time. I kinda messed up the switch placement, I'll go back later, after it's working, and get that all straightened out and looking nice. Besides, I gotta make sure it's ergonomic and easy to use before I obsess over looks. Of course the Led's are to indicate which gear you are in. I'll do a full write up in the Sucess Stories, assuming it is successfull
