Just looking around again for some new ideas and I found something I like!
Look at these...
I think I'm getting them and mounting them across my hood like so... on each side (2"x22")
Into the taped areas... passenger side actual example size (center rectangle)
to be functional there will be some hole saw drilling
I've already got these push button hood pins coming as well so lining them up in front would be in order... (1.25" round)
All aluminum to match my rad and other bits of aluminum around the car...
(ECM delete by me)
(Vent deletes by ROB5625)
ANyway.... has anybody done louvers on a B15 yet??
I'd like to see some more options
Maybe I read it wrong, but without the under pan, having the hod spacers and vent holes, minus the lower one, should still improve pressure changes and be functional.
I just found it funny that they put that hood scoop on for the intercooler, and found out the scoop was venting rather than scooping.
I think under pan is important to lower turbulence, but my car is friggen low, so there isnt going to be much, plus I have a PU lip to install... I'm going to close up the bottom of the front bumper cover, and add a top air diversion panel to ensure good pressure through the rad. Then the hood vents as done on the orange spec are well positioned to vent pressure out, but an additional vent... one near the windshield will allow air to flow into the compartment and cool the rear of the engine as well... (I'm thinking VQ header heat in back). Maybe I read it wrong.. ha ha... better read it again... the three piece jeep louvers are sounding better....
I think vents anywhere from the mid range to the front would be best. A vent up in the front half showed would an area of low pressure, reducing the engine bay pressure.
I got it backwards, the lower the better.... so the s2k vents, having the larger ones lower would be good, but the uppers would be some what unfunctional.
There is this bit... "So you wouldn’t site a bonnet outlet vent close to the windscreen" and "the greatest difference between the underbonnet and overbonnet pressures is at the very leading edge of the bonnet,where it is 0.6 inches of water.(However,it’s very hard to site a vent here and moving backwards a little to the front third of the bonnet still gives 0.4 inches of water pressure difference.)"
I had it wrong a bit too... front third of hood is the key area to vent.
I was thinking drawing air in at the back is good, but probally wanna close the hood 100%
So the spacers lifting the rear of the hood is bad? It should have some effect since it changes the dynamics of the pressure area being elevated over the windshield, which the article didn't really go into.
So I will probably just do the lower two then and leave the upper one intact, giving me openings on the lower 2/3s of the hood.
Well I think it's bad if you have functional vents on your hood relieving pressure, and the hood spaced... because of turbulence... you would be less efficient. There is always the try it and find out method
Well the spacers are easy to fix, and considering I already have them, they will stay for now. Glad though we talked it out, so I will only be doing the lower two holes on the passenger side.
I think we'll find out soon... Lol. But venting more toward the front of the hood is very possible with it.
I think it will almost make the hood look like it came like this from the factory.
Thats just under hood temps, do you have a gauge to read water temps? Thats more or less the issue, does the pressure drop or increase uder the hood effecting the air moving through the radiator and intercooler.
im going to keep a close eye on this thread i have a pare carbon hood oem style 04-06 that need to be painted but before i paint it i want to modify it so once its painted it looks oem
Got the first few holes cut. I'm going to need to prep and sand this thing and send it off to be paint professionally, but its going to look badass. Don't think I'm going to follow the pattern of the under hood brace. It kinda curves back up and would look better slopping into a triangle matching the line of the hood. Here's a quick peak....
Now that's a work in progress! Can't wait to see it finished. What kind of mesh... same as the s2k.... this is so original man...
