I don't think it'd be on long enough to heat the intake up THAT much. At key on the lift pump only runs for 20 seconds am I right? If so it takes roughly 5 seconds for the heater to put out full "flame" so your left with about a good 15 seconds of burn. After that you'll have to start at which point the heat will travel with the airflow.
I'd imagine the best spot for it would be in the manifold, but 7/8" is a big hole to drill, with lots of shavings, and I don't feel like taking it that far apart to get it off, again.
Once I get it goin I'll do some testing with an ir gun to see where the heat is goin for sure.
I like the idea. So don't get me wrong
... But above the silicon hose between elbow and valve cover is a very small place to install it and it's also relatively close to the weeks elbow silicone hose. But heat goes up so it may be ok. We need a glow time to warm up the heater then start the fuel flow.
We can have a switch installed to kick the warmer, then another one to start the pump on demand. Radio "ignition" plus works when you turn the key "down" (like unscrewing it - to start the radio when engine is off), so the tank/lift pump can get its plus from the radio through a relay and switch. What I mean is to turn the key to start the radio when engine is stopped, this can send power to the switch for the warmer fuel, turning the switch on will start the fuel pump which will push fuel in the injector and then start burning since it's hot.
I still think this is overkill for us in Ohio, weeks intake heater is more than enough, but may be a very good system for somebody in Alaska or Canada.
Can you calculate the amps required for the warmer? Weeks glow plug (from intake heater) has a 30 amp fuse.
