  1. thanks guys! The way the VG's are mounted on the wings are exactly as Jon mentioned.. The VG's really take effect at HIGH angles of attack.. (ie right before the wing stalls) The aircraft stalls because the aircraft exceeds the angle of attack and the airflow no longer accelerates over the leading edge of the wing and buffets behind the wing. If you notice the way the VG's are mounted on the Cessna's, at the highest angle of attack to maintain slow flight (55kts) the VG's are just below the highest point of the leading edge.. allowing the VG's to take effect and keep the air flowing and accelerating down the wing. Now in a Z car.. the air flowing over the top of the car actually accelerates down the rear hatch before it seperates from the boundary layer. The point of the VG's is to increase the boundary layer seperation and keep the air accelerating down the hatch, which increases the effectiveness of the spoiler!
  2. WOW!! Scott that looks incredible!! Everyone is shown me up! LoL.. mine was a ghetto 1 hr project.. haha very impressive! I have some work to do!!
  3. OK.. I called a company by the name of MicroAero who produces vortex generators for Cessna, Beechcraft, Piper etc.. and I spoke to a wonderful technical ops manager. He said that mounting the VG's parallel with the wind is NOT effective... They mount the VG's pigeon toe'd on the leading edge of the wings which can be as high as 30* degrees.. He said there should be no difference in which direction the VG's are mounted (pigeon or duck (opposite)). Here are some pics to support the data
  4. Wait a sec... I was looking at SDI's VG's... Seems mine look backwards.. BUT I followed the directions from Vortekz.. and this was tested effective in the windtunnel Which is right?! http://www.mitsubishi-motors.com/corporate/about_us/technology/review/e/pdf/2004/16E_03.pdf I was reading Mitsubishi's article.. and they seem to be at ZERO degrees.. hmm
  5. that is very impressive Dragonfly I am still trying to figure out a way to seal the intercooler and radiator with the opening I have.. its very very difficult to get right and ALOT of time to get it sealed perfectly.
  6. Welp.. I have been wanting to install my vortex generators for sometime now.. I bought them for $19.99 from a company by the name of Vortekz Generators. There are supposed to be installed at various angles.. the inner 4 are 15* degrees from the roof line.. the next outer VG is 10* degrees, then the 2nd to the last are 5* degrees then the final outside VG's are parallel with the roof line OK OK i realize in the very last picture they are not PERFECT.. but it's hard to do i'm telling ya! But it still does its job.
  7. #6 is the furthest cylinder from the waterpump and cool fresh antifreeze.. Cylinders #5 and #6 run the hottest.. you probably blew the headgasket on cylinder six which blew cylinder fives seal. Increase heat = increased chance of detonation or pre-ignition. Best way to tune is individual EGT sensors on each cylinder much like aircraft do... but clearly this is hard to achieve. Tuning on the other hand for each indivdual cylinder and timing is expensive and difficult to do
  8. you would have to use a proportioning valve .. the handbrake would not be used.. the calipers do not have a manual mechanism..
  9. I have a carbon fiber hood (fiberglass bottom/carbon top) which is still very light.. when its hot outside.. to prevent heat soak I open the hood which allows all that hot air to escape... yes i've driven it unlatched at 100mph plus and I did not see it rise that much.. only 2-3 inches. maybe its the airdam I have
  10. Daniel congrats on fixing the problem yes you can post your findings on MSefi.com which is the megasquirt forum
  11. I had that SAME problem with my MS1 2.2pcb I dont know what happened or how it fixed itself.. but it did
  12. I havent had any issues like that.. weird. Mario I ran a piece of metal just like you mentioned!! did it last week!
  13. the Ferrari F50 has fans in the hood.. designed to suck the car down to the ground and provide downforce.. which is awsome
  14. omg.. i just woke up lol I tried to get into DC-10 (bar) downtown .. and they wouldnt let me in because I reeked of booze so bad. Now thats an acccomplishment haha I ended up humping a pink volvo too.
  15. haha this effn rocks!! hit up the bars at midnight last night.. bein a pilot i cant get ANY underage tickets or anything so i've had to be responsible! Now im 21!! haha this rocks
  16. http://www.e31.net/engines_e.html This has AWSOME illustrations on crank designs!
