I drove all through southern cali and Nevada last year with no injector cooler and I was fine.... except for my radiator leaking but that's another story.

Yeah I Hear Ya On That. Your Club Planning On Hitting Vegas This Summer?

Hehe, unfortunately, no. I think on our last trip we were maybe 100-200 miles north of LV though (we were basically east of Bakersfield before we turned back up the Bay Area). It's all empty, hidden byways and highways where we go. ^_^

I just got a new multimeter that has a temperature probe function. Maybe I'll test out the temp of the fuel rail (finned Pallnet rail) both with, and without, the aux fan.

i can drive my car for an hr. when i stop. i can grab my fuel rail and it's just a lil warm. but mainly I'd say around 70Degrees maybe a lil higher. she stay's pretty dang cool.

Wow, that's definitely different than mine. I'd burn myself if I held onto my rail, though I'm sure my whole engine bay is just plain hotter since it's a turbo. All the heat is rising off the intake manifold and probably just saturating my rail.

70 degrees? I can't see how that's possible... your outside temp is prolly hotter than 70 degrees, and your rail is in an enclosed hot engine bay. Like HeatRave said, heat rises from the exhaust mani... it's going to heat the rail too.

70 C ? :d .....

no. when i checked. it was only about 50 or so out side
