Fuze Posted July 17, 2012 Report Share Posted July 17, 2012 Looks trick, but you better keep it dry! You don't have to submerge it to suck in enough water to hydro lock an engine. Link to comment Share on other sites More sharing options...
dmyers151 Posted July 17, 2012 Report Share Posted July 17, 2012 The intake tube looks a little on the small side. What is that, 2"? Link to comment Share on other sites More sharing options...
TexasQuest Posted July 17, 2012 Report Share Posted July 17, 2012 Nice but sucks that you got to take the fender off to change it. Have fun with that..... 1 Link to comment Share on other sites More sharing options...
speedyquest Posted July 17, 2012 Author Report Share Posted July 17, 2012 (edited) @ Dmyers151: The intake size directly from the filter is 3 inch. I then used an adapter to reduce it down to 2.25 which is what my intercooler piping is and ironically the size of the intake of the turbo. @ Fuze: Ya keeping it dry is a concern but I've taken care of that. With the fender liner in place the only way water is getting to that is if you were to drive thru a MASSIVE puddle big enough to reach well over the tire. With that in mind you may think "well Allen then how is it getting any air?" well plenty of air is coming from the front of the car. There is quite a few places for the air to enter that space that is before the radiator. I do also plan on adding some type of duct to pass air thru that square hole that you see in the picture thats just before the filter. When I tested this the car had no issues breathing the way you see it though. @ TexasQuest: Yea lol I wont lie its not the easiest thing to take off but its really not bad either. If you take your time and dont rush its not hard at all. Edited July 17, 2012 by speedyquest Link to comment Share on other sites More sharing options...
GLHS Posted July 17, 2012 Report Share Posted July 17, 2012 Nice little setup,looks good and sure it help with the cooled air i like Link to comment Share on other sites More sharing options...
Threedoor Posted July 17, 2012 Report Share Posted July 17, 2012 The intake tube looks a little on the small side. What is that, 2"? I am with dmyers on this, from personal experience. I had a 2.5" cold air intake pipe going to the turbo on my Galant VR-4. I was doing dyno tuning on a 2WD dynojet dyno (using welded center diff and removed drive shaft) and I wasn't making the power I should have been with that setup, only about 300. When I was almost out of time, I listened to the advice of the dynojet operator (who was also an experienced tuner / builder) and pulled off the intake pipe. First pull without the intake I had to back out because boost was now about 8 psi higher than with the intake. After backing boost down to the previous level (22 psi) I was making about 50 more wheel HP than I was with the intake in place, and I had compressor surge on spool up that I had never had issues with before because it was getting so much more air. Minimum inlet size I will use now on something I build is 3" for a short intake, but for a longer one I would prefer 3.5" or larger. As far as the turbine inlet size, it is best to have a tapered transition from your intake pipe to the turbine inlet over the last 6" length of pipe... but that is harder to source so most people do a step size transition at the turbine inlet.

JohnnyWadd Posted July 17, 2012 Report Share Posted July 17, 2012 That a cool setup. There is one i saw where they used a trash can like an office one and trimmed it to fit in the ingine bay corner. Link to comment Share on other sites More sharing options...
Technology Posted July 18, 2012 Report Share Posted July 18, 2012 ebay 3" honda intake piping. Probably 5 bucks. Or 4" for no reason at all... Link to comment Share on other sites More sharing options...
speedyquest Posted July 18, 2012 Author Report Share Posted July 18, 2012 @ Threedoor: I appreciate the info, I didn't honestly think it would make a big difference since the fact that the turbo inlet is only 2.25 as well but if its known to help I have no issues switching it to 3 inch all the way to the turbo. That said this was also simply done with piping I had laying around so its not as if this cost me anything. I'll definitely try out the 3 inch piping as well.

yzrider Posted July 18, 2012 Report Share Posted July 18, 2012 Your thread titles equation doesn't match up with the picture. I think you meant filter - fender = colder air. Who knew algebra on sqc was possible. Link to comment Share on other sites More sharing options...
speedyquest Posted July 18, 2012 Author Report Share Posted July 18, 2012 Well... you would be correct IF I didn't put the fender back on. I certainly dont plan on driving around without the fender on there lol. So yes my title is correct sir Allen Link to comment Share on other sites More sharing options...

I am only saying this because my brother hydro-locked his Subaru with the exact same setup, fender liner and all. Water goes everywhere when you hit a big puddle or hydroplane.

Technology Posted July 19, 2012 Report Share Posted July 19, 2012 If you don't bend any rods or valves when you hyrdolock an engine, you can just unplug the spark plugs and crank it for a while Link to comment Share on other sites More sharing options...
speedyquest Posted July 19, 2012 Author Report Share Posted July 19, 2012 Thanks for the heads up Fuze. That is a very real concern and I'll have to take every precaution to ensure that doesn't happen. Allen Link to comment Share on other sites More sharing options...
Skippy Posted July 23, 2012 Report Share Posted July 23, 2012 (edited) At one time I had cut a hole in the bottom of my filter can and ran a 3.5" tube (I think) to the small front small side spoiler opening and used something to wrap that and then go to the tube. It more or less created a RAM air type system but more importantly it sucked in clean fresh air and not engine bay hot air. Since I was concerned with getting water in my system if I got caught in the rain I had a tennis ball in my car I would just put in there. I may go back to a system like that when I do all my current upgrades being I will be driving it rarely enough that water should never be a concern.

Happened to my WRX as well during a heavy rain. But granted, the filter was not out of the way and up as high as that picture Link to comment Share on other sites More sharing options...
