76 subaru conversion Options

[carphappy]

hi everyone. several years ago i built myself a jdm ej20k subaru powered 914. unfortunately i did not document my progress. because it already had an aftermarket body kit installed i had no ethical reasons not to install a different motor. i am using a diy megasquirt ecu with the stock cam and crank sensors to control the motor. to say that i learned a thing or two along the way would be an understatement. thanks to everyone who has done a subaru conversion before me. your posts have inspired me and helped in numerous decision making situations. here are a couple of pics.

I wonder,.how much air turbulence,.MAY be created under the hood,.. with the hood scoop/vents in which ever direction,front or back,..I would think,.in at bumper,..out at top of hood towards windshield...??? would be the best flow pattern..

That is the best flow pattern- that area in front of the windshield is a low pressure area so it you fill it with air from the front of the vehicle not only does the low pressure pull the air through the ductwork, it also helps stabilize the car at higher speeds. I'm not a fan of the look necessarily but it does work well so make it as pretty as you can... the general math works out that you need twice the outlet area as you have for the inlet area and the straighter the ductwork is, the faster the air moves and which makes it more efficient. I'm still not a fan of the way it looks tho... (IMG:style_emoticons/default/dry.gif)
