coltboostin Posted June 24, 2015 Report Share Posted June 24, 2015 Obviously, sucking hot air from the engine bay through a tiny filter is not conducive for making horsepower. So here is what I am currently working with. (Just a short filter on the turbo behind the headlight assemble with I opened up in this pic) Turbo sucks 100% hot air. http://i1003.photobucket.com/albums/af154/coltboostin/LsxRx7/IMG_20150624_095611622.jpg Option A-Straight shot. Pro's -Straight shot! In theory-maximum airflow -Removes the weight of the headlights from the front end -May look cool with a simple screen replacing the OE headlight cover Cons -Have to build and alternative headlight system to sit in the FTP section fot he bumper -Have to duct cold air to it, or run a screen in place of the OE headlight cover -Would not work with FC2000 bumper I may switch to in the future. http://i1003.photobucket.com/albums/af154/coltboostin/LsxRx7/IMG_20150624_095753378.jpg http://i1003.photobucket.com/albums/af154/coltboostin/LsxRx7/IMG_20150624_095801285.jpg Option B Pros- -True COLD air coming directly from the brake duct cut out in the bumper -Keep 100% functionality the 80's pop up headlight action -Can remove filter and add a Ram Air Velocity stack for track duty -Most room for a long filter-full 9inch-least restrictive Cons- -Would have to have 2 tight radius 90' bends in the intake. Would this hurt flow? -Heavier-keeping the OE headlight- http://i1003.photobucket.com/albums/af154/coltboostin/LsxRx7/IMG_20150624_095828394.jpg http://i1003.photobucket.com/albums/af154/coltboostin/LsxRx7/IMG_20150624_095835111.jpg http://i1003.photobucket.com/albums/af154/coltboostin/LsxRx7/IMG_20150624_095845024.jpg Opinions welcome! I am leaning towards Option B, but would that pose a significant restriction over Option A? Quote Link to comment Share on other sites More sharing options...

Dafunk13 Posted June 24, 2015 Report Share Posted June 24, 2015 Option B. The bend won't hurt too much, provided you're working with enough diameter. Quote Link to comment Share on other sites More sharing options...
greg1647545532 Posted June 24, 2015 Report Share Posted June 24, 2015 Option B. The bend won't hurt too much, provided you're working with enough diameter. This. Even better if your bends have a decent radius on them. If it were me, I'd mount the filter directly on the turbo and wrap it in a shroud, then feed cold air up from the bumper through that hole that's sitting right below where the filter would be. That would help with the packaging. Quote Link to comment Share on other sites More sharing options...

Geeesammy Posted June 24, 2015 Report Share Posted June 24, 2015 Option C, cut hole in hood, stick air filter through said hole, clamp that bitch down and pray she holds at 140 Quote Link to comment Share on other sites More sharing options...
Jewtoys Posted June 24, 2015 Report Share Posted June 24, 2015 I like that. Is there a $20 Chinese version? Yep, all over eBay ha. You could also make a air box and sheild it from heat, and get something like this to work. http://m.summitracing.com/parts/vnt-35753 http://m.summitracing.com/parts/vnt-35853 They sell multiple designs, but you could always get thrifty at Home Depot Quote Link to comment Share on other sites More sharing options...

You are not going to get any ram air enough to make much difference with those beastly turbos anyway I bet. Quote Link to comment Share on other sites More sharing options...
coltboostin Posted June 24, 2015 Author Report Share Posted June 24, 2015 Option C, cut hole in hood, stick air filter through said hole, clamp that bitch down and pray she holds at 140 Option A is more or less than since the filters would be basically be replacing the headlight assembly. That is a good idea. You are not going to get any ram air enough to make much difference with those beastly turbos anyway I bet. Its not really the turbo size-its where its at on the compressor map-if its at the edge of its efficiency range pressurized air coming into the inlet will move it back and free up some power. I hate to use psi as a reference since its a mass-flow thing, but think of it like this- Turbo A is 90% efficiency at 30 psi, and only 70% efficient at 34psi on a 2.0L Maxes out at 35 psi.. if you can get 4psi of charge in front of it, it will move air at 90% efficiency at 30psi, and will have a higher max boost around 39psi That being said-there is some gains to be had with true ram air there, but your right in saying probably not much considering my boost levels.

greg1647545532 Posted June 25, 2015 Report Share Posted June 25, 2015 I've cut through sheet metal with a hole saw before. It's not pretty but if you're willing to take the time it can work. Or you can drop the coin for an actual sheet metal hole saw. Quote Link to comment Share on other sites More sharing options...

C-Mart Posted June 25, 2015 Report Share Posted June 25, 2015 I had to cut two small ovals recently - 1.5X5"ish. Couldn't find a good way to do it so I used an abrasive dremel bit and too much time. Quote Link to comment Share on other sites More sharing options...

Metal blade on a jig saw? http://www.sencan-tools.com/photo/original_3e70502f120581c12b69dfbf6c77cd67/electric-portable-jig-saw.jpg I have a HF jigzaw but only wood blades, and zero time to fuck around. I had 1 hour of "loud car time" and I had to take advatange of it. I mean yeah cuz more power is what that car needs. Not more power-easier power. More power will come with more motor Quote Link to comment Share on other sites More sharing options...
