I have quite an agenda with my old HPI Super Nitro Rally . Taking my que from rbinnovation's I have 3 main projects I am working on. I've decided to do these to A) improve my car's cooling and thereby increase performance, acceleration, and speed B) having something to do on it other than bolt on boring old parts from the internet and C) seperate my car in some way from the average enthusiast. Goals!!! 1) I am making an intake scoop that feeds air from the front of the car behind the body's grill and inside the hood scoop using some rubber hosing from Radio Shack, a CPU Fan case for the scoop, and a dremel of course. 2) I am making a radiator of sorts that sits on top of the heat sink that blows fresh air onto the sink using a 1" by 1" micro CPU Fan my brother gave me, a toggle switch (from radioshack) and a 9v adapter and case holder that wires up to the toggle switch using some metal tape (also from radioshack, imagine that!). 3) I have a larger, 1.5" by 1.5" CPU fan with more power that I will mount at the front of the car behind the windshield aiming back towards the exhaust system and header to cool that as well. This will also be using a double throw single pull toggle switch in tangent with another 9v source. I am extremely excited about doing this and have managed to get all the materials for goals 1 and 2 and the fan for goal 3! Just thought I'd share my current ambitions to customize my car!
