Interesting. Keeping it under 200F under the hood might be a challenge. Figured the coolant temp on long climbs up most trails is going to hit 200+ plus then you've got a lot of exhaust heat in that situation too.
I've had some thoughts as to whether it could be mounted back by the fuel tanks on a pickup. Like in front of or behind the tank selector valve. Or maybe on the opposite side but that would add a little complication to the fuel line routing.
Thinking more about the under hood temps. I ran my K5's engine cooler because it was carb'd so the engine never hit 200F. I also had a temp gauge in the power steering system on the bottom of the remove reservoir which was mounted off the brake booster about 6" above the headers. Power steering system had a cooler as well; the gauge sender was located on the return port from after the cooler. Power steering temps always mirrored engine temps. So this would lead me to believe your under hood temps are probably going to mirror the engine temp, which makes sense. I wonder what engine temps the FiTech would work best at?
Either way, in a trail condition you are going to be right on the borderline of the 200F mark.

Yeah it seems like it would be pretty easy to hit 200 degrees. Is he talking actual fuel temp?
Think so
I mean fuel temp inside the canister... it seems like it would be pretty hard to get a gallon of gas to heat up to 200 with a constant flow going through it. Idk? I'm not going to be running the FCC but I am curious to see how it works.
I wonder how much fuel flows through the injectors at a part throttle climb up a moderate trail. I'm thinking about something like the beginning of Chinamans or Spring Creek. In other words how long does that gallon of gas sit in the FCC. Or the trouble could come if you have to stop half way up the climb and your stuck idling with no air flow after pulling hard for a bit. Although the cooling fans would be creating air flow - at least one would hope.
I didn't figure it was much.
Pack it with dry ice.
yes they do
Yeah there's not any big gas savings with big motors...
Big gas motors are cool though.
damn straight
I would have thought they ran hot. At least, for the purposes of this discussion (heat flowing through the engine compartment). Am I wrong?
With everything in good shape, the big stuff doesn't run hotter. IMHO
I did have a bad NAPA water pump that gave me fits for a while. It was a new one, but it didn't push coolant well. So when I got frustrated, I bought an Edelbrock. DONE!

Mine 468 ran cooler than my 454 but I think the 468 has an aftermarket high flow water pump. It doesn't resemble a stock BBC pump and it's aluminum so I'm pretty sure it's not stock at least?
I also have a cowl hood so that helps too.
Not talking about engine temperature, I'm talking about the number of BTUs flowing from the radiator, block, and exhaust. The stuff that heats up 1-gallon fuel containers that aren't supposed to get above 200*F. The BBC should be throwing off more waste heat and running a hotter engine compartment, no?
Well , since you put it that way, I would bet that you are correct.
