Evening mate,

It just seems a tiny bit crazy to spend all that money on a top end setup and cooling system and then blow hot air over it all haha

Ive been in and around racing of various forms since i was 8 or 9. most recently drag racing in pro-et and pro stock with analysis and input on two top fuel teams aero setup. TBH most of my experience is in engine and transmission building aerodynamics was sort of a hobby formed through enginebay layout and cooling. I did a year studying fluid dynamic basics at university but dropped out as apart from the fuel crucial rules most if it is useless at the low speeds cars travel (compared to aircraft etc) and a few basic theories solve 99.9% of problems. My real center piece was a car develped with an ex f1 engineer for no reason other than we both wanted to see what you could do using the technology the racing world had banned i.e active dowforce, ground effect df, hydralic valve operations (i.e no cams) etc etc. The final car (based on a road going rx7 chassis, strengthened and seam welded) held 5.1g's offside cornering force at silverstone in 2004 before the tyres let go. Nearly level with an f1 car and not damn bad for what could still be road legal if you had a friendly mot tester!
What are the regs like in your groups?

Back to the world of electrical speed, if i had the space id have the setup completely flat with direct laminar ducting from and exterior wall and straight out the other side but i cant get away with it at the minute haha although we had some experiments with a chimney type setup on a unit in a sealed box whereby the top pipe (approx 3" od ran from the top of the box up3ft to open air and the tube attached by a 45deg bend piece at the bottom of the box stopped approx 2 1/2 foot above the box. As the board started to heat up you could feel the cold air being sucked forcibly into the inlet tube due to the heated air rising out of the top pipe.
Never took it any further than that but well worth a look especially with a fan or to in each duct to help keep the momentum going
