You're NOT putting a Japanese engine in a German car, are you?

nice duct work BUT i thought the consensus was that suby did not require much air flow.

Well done Kent! So the real question is. Did it fix the heat issue with your tank?

I've driven the car about 5 times since completing the new duct work. Usually for about an hour at a time with temps ranging 87-92F. The gas tank has remained cool to the touch after all test drives, so far. (IMG:style_emoticons/default/piratenanner.gif) After this evenings drive I touched the metal ducts and the right side was hotter than the left. I wonder if that Celica dual core radiator passes the water thru one side before the other? (IMG:style_emoticons/default/idea.gif) I also installed a new fan controller today so it may be that the right fan was the only fan activated. I'll install some small LEDs to show when the fans are running. I can't hear them and I don't want them running when on the hi way. My old Derale controller ate it so I replaced it with this Dakota unit. I've always been pleased their attention to quality and am thus far happy with this purchase. They require a dry cool climate so I located it next to the fuse panel. It's programable too; whether you have 1 or 2 fans; 1 speed, 2 speed or variable speed fans as well. Can use your engines temp sender and gage or get the info from your ECU with the $40 adapter. One advantage of this methods is the controller knows your speed and will shut down the fans on the hi way when connected to the ECU. I went the simple route with a single sender. I may have some in/out parameters to dial in but so far so good. The real test comes tomorrow. I will be on the 15 S 80 mph in 92F+ and I'll be running the AC. Hopefully I'll make Cruising Grand. I've had to abort enroute to the last 2 events. (IMG:style_emoticons/default/sad.gif)

This is the 12v spade connector that supplied the old controller.

Remnants of the old relay. Notice the residue on the male spades? It's melted circuit board.

Very nice,

Looking at it, I see an A/C terminal. This traditional is used to run a fan to pull air through the A/C condenser even if your coolant is not up to temp. Not sure if you need to hook it up or not. Here in humid Ohio, yeah I would hook it up.

Best of luck on the trip and let us know how it goes. (IMG:style_emoticons/default/beer.gif)

You're confusing 2 core with 2 pass. Celica rad is one 1 pass, sounds like only 1 fan is running.
If you have it set for 2 different run temps if might not be hitting the 2nd. My second fan only comes on in town on hot days.

Well, the trip was a smashing success. When I left Temecula it was 90 something degrees. I ran 80mph (that is the minimum speed limit in SoCal) with the AC blasting and the fans never even came on. Temp stayed centered, which it always has, but the big news is the gas tank was cool to the touch. (IMG:style_emoticons/default/piratenanner.gif) The return trip was the same speed but temps were down about 6-8F and I didn't use the AC. Same result. Cool gasoline. Now the fuel pressure hasn't dropped below 49psi since the fuel is no longer piping hot. My cabin is now much cooler too. I think I can finally put this major PITA to bed. That was an 18 month long puzzle. (IMG:style_emoticons/default/headbang.gif) Unless there is a Gremlin hiding somewhere this car is basically finished sans a paint job. Everything now runs together harmoniously.
Elliot once asked me whether it was more difficult to build this car than it was to build an airplane. Now that it is finally "ironed out" I can say that it was positively more difficult to build this car than the airplane. There will be the usual maintenance items but nothing worth posting in this build thread. If I discover anything that doesn't work I'll mention it here. Other than editing some of my boo boos out of this thread I'll ask Andy to move this thread and call it a wrap. Thanks to everyone that contributed to this build.

Whoa, whoa, whoa! Move the thread? Car is done? None of this is making sense to me! (IMG:style_emoticons/default/blink.gif) Maybe I drive a completely different type of project then you? Done? Is that possible? I thought without consistent tinkering a 914 will progress to its natural state of rest on jackstands? (IMG:style_emoticons/default/slap.gif) Say it isn't so!
