    Homemade Intake Installed

    Well today I finished up installing my homemade intake. It was that one that GroverDill ordered for the both of us. Just had to trim down the aluminum intake tube. It was ordered in 1 foot but probably trimmed off about 4 inches or so. Here are the pictures. The aluminum pipe was pretty beat up and raw. I used some steel wool and some polishing compound to give a little shine. Hopefully I can get to a Dyno soon and see if there are really any gains.

    WHERE IS MY TUBE!

    FYI the 3.5" clamps I bought would not fit on the MAF connection. So I would suggest a 3.75" for that.

    Looks nice, I want mine done!

    4" off would be perfect. Cough.

    May want to reseat the silicone elbow on the throttlebody and make it and the clamp square with the world.

    Position the clamp on the MAF square with it as well. Make the hump-hose do its thing.

    Aye, 3.75" or 3.80" *cough again* clamp would do it. 4" is overkill in a t-bolt.

    If it were me, I'd chamfer the inside edges of the aluminum tube.

    Or is that giving too much away in FFV land?

    Where'd you get the engine covers?

    I actually noticed that it didn't look seated correctly at the TB once I saw the pictures. I will go out and re do that part.

    The FRC's I bought used off a member here who said he got them from you.

    Re: Homemade Intake Installed

    Yeah, my tube came pretty $hitty also. I was already pi$$ed cuz the 3.5" tube was almost three times as much as anything else.
    If you have trouble with it coming appart, just loosen the air box. Let it move a little with the engine.

    Re: Homemade Intake Installed

    First off, looks nice and I appreciated the parts list from groverdill's intro post. For people who didn't see it and are interested, it's located at the link below:

    http://www.cadillacforums.com/forums...v-owner-3.html

    Vecstasy, groverdill, or if Stealth ventures back from his uber forums, you guys did a 3.5incher right? If so do you feel you could squeeze an extra 1/2 inch in there and put a 4inch tube in? Soon as my warranty is up, i plan to do a lil motor makeover that isn't warranty friendly and I don't want to order the parts for a 3.5in and find that a 4 would have made it. I am no specialist, so for all i know it might be not beneficial or stupid. I currently have lingenfelter box and the MAF wire plug is awfully close to one of the pulleys and i feel like with a lil engine mount wear, engine torgue, and Indiana tank traps (pot holes), it rubs. So i would like to make a new tube and move the sensor. Others with the Ling box can speak up on how they remedied this or if i am the only one with this.

    Once again, I want to say thanks to Stealth for making these in the first place and inspiring others to follow. Thanks to Vec and groverdill for your info and updates.

    I don't think a 4" tube would even be close to fitting.

    Re: Homemade Intake Installed

    Thanks for the compliments guys. I drove the car tonight and it felt really good. Of course that could be placebo but I need to get to a Dyno to verify that it actually did something.

    Cadiblk: I really don't think a 4 inch tube would fit. It is pretty tight as is.

    I have heard a few times in my day that a tube of mine won't fit, but after a few beers and creative persuasion, anything is possible.

    Bum deal that airflo's aluminum is all beat up. I plan on insulating my tube (always wrap the tube ), so my friend is going to give me a piece of ugly stainless steel. That $20 foot of aluminum is a rip, when they are buying it for prolly $2-3 a foot for a 20ft rod.

    Well I've had too much fun with this thread with all these tubes, rods and things being beat up, so since it is near 3am here, I am out.

    4" will fit but one needs to watch to make sure it doesn't rub on the powersteering pulley. Ran that way for a few months and then noticed the polished pulley face and silicone coupler about cut all the way through. Stick with the 3.5"

    ^ DING DING DING. This is definately great advice. It took me a while to gifure this one out. Once I did though, no more weekly futz-ing with CAI evey week.

    Like Rick said, a 4" will fit, but in addition to the PS pulley, you also have to worry about the radiator support bolt eating a hole through the tube on the other side. You could install a 'slim-line' bolt in place of the OEM one, to help mitigate that issue, but the bracket is still there.

    Additionally the MAF is 85mm (just under 3.5" in size), so I'm not sure there is much of a performance gain to be had on a stock cubed engine, going to a 4" tube. Bottom line is it's probably more of headache than it's worth.

    Well I wasn't too fired up on the way the intake tube itself looked. I pulled it off today and sent it out for powder coating. I am going to get it coated in a Silver Sparkle Metallic and I hope it matches the exterior of the car. It should be done in a couple weeks.
