hAHA.. Well today i doug up the scraps of 4" that i could find, none being more than 6 inches long, half of them half way flat and decided since silicone intakes.com has my 4" pipe on backorder i'd just chop up scraps and make an intake to put a filter on my 4" inlet turbo

here's some pics, lots a pieces and i was running my argon dead on empty so the welds are ugly, but this will do for now.. it will at least let me get a real K&N fgilter on the thing (all i had previousely was a screen right on the inlet to get by) but today I had some time, energy and drive to burn up the last of my argon before i trade in a tank with anything left in it (them bastardds keep jacking my prices either way)

here's some pics.. lots a little pieces went into it LOL these were litterally all things i shuold have thrown away from other jobs but kept under the bench for just such an occasion


Now that i have this made i'm off to get a new bottle of argon and a real filter than can flow some air

THIS WAS A DAMN TIGHT FIT!!!!!!!!!!! I'll either grind and polish it later or make another one, i think i'll re-do the main upper pipe and see what i come up with here some day soon

Either way this has to be better than drawing through aluminum window screen from right behind the radiator fan LOL

Nice, I love to see scraps go to good use.
 
hahaha thanks fellas, it actually made the car pull a LOT better getting a fresher air supply and having the larger suraface area of the filter to draw through compared to the 6 layers of fine aluminum screen i had on there not wantig to risk getting anything in the turbo

I had my argon bottle reading less than 200lbs when i started (Q size bottle about 4 foot tall) and when i was finishing i had no post flow, gauge wasn't reading and the flow was turned down so low it didn't register on the new bottle when i got back home with the fresh one :D LOL

I only wish the piping wasn't so beat up so it would be easier to put a polish finish on it but oh well, it was free

the intake pipe made some HUGE gains in my data logs both as far as fuel consumption/boost per RPM range, as well as pulling to 8500 RPM much easier than when i had only the screen on there. THe bernouli effect has something to do with it i'm sure but i'm betting the air coming in at 87* instead of 185* + from the radiator made some changes to things :) best thing is it only cost me a few dollars to build it all together..the only thing i paid for was a few hose clamps and the HKS 4" coupler

that makes me wish i could weld descent

Welding is easy. Those are (functional) welds. What I call beauty welds are those nice even layerd beads, overlapped over each other like waves of water. Takes time and tons of practice.
 
Arg, I'm going to have to do the same. Looks good for a mig. I always say the only difference between a pretty weld and a ugly weld is a grinder... :D I had planned to use some cheap 4" adjustable ducting and fiberglass.

I would have to agree, if it weren't for the fact i know i've shown better work i would be ashamed to even post pics of that pipe LOL. I actually started working a little more on a 3" DP for myself under the same concept of using small leftovers of T304 SS that i have pie cut or had left over from other jobs so that i can finally get rid of the hideous thermal R&D bottle neck and matching 2.5" DP i've been running for 13 years LOL

I do so much work for others i never get time or motivated to work on my car but i spent a good 8 hours doing new wiring, running new inputs outputs and all sorts of goodies on my girl today :D

Now i have 2 step, fans, antenna, and other variouse rockers under the radio here the EQ space is. Got rid of the MSD DIS-2 so i can sell it towards injectors, moved my J&S safeguard to an awesome hidden and protected spot where i was able to pull over 31 foot of wiring from the ignition sustem!!!!and much more from other places and cleanups.. too tired to think about listing it all right now but i assure you i will post about it :D


What i want to do now is take the oassenger duct from the bumper and make a cold air duct up into the engine bay where the filter is (and i still need aa large REAL K&N instead of that aspect or whatever crap POS that's on there from the parts store but hey it was given to me and was 4"

Here's some pics of the rewiring i did today, most of these switches were hanging loose or tucked away some where only to be found by following the wires. this is much nicer.

The part on the dash was my first experience putting anything in that "padding" i'm making a fiberglass mold to clean it up but it doesn't look as bad in person as it does in the pic (that's the toggle to arm the nitrous, couldn't fit the gaurd on it cause of the padding :( )

The shot of the radio is laid out as follows

Black Rocker is antenna up and down
Red rocker is Both cooling fans on speed 3
small momentary is 2 step rev limiter (5200 RPM)

the night pic, doesn't show the global fuel trim knob under the reare defrost (allows me to add or subtract certain settings of fuel, timing, boost etc.. now it's set to +/- 12.5% fuel.. Also since the key isn't on you can't see the profec in the glovebox, but you can see the Bright blue LED's i replaced the interior bulbs with today as well (i did every ashtray, lighter, and panel light into blue LED)

The horrible dash hole (again not so bad when you're in the car) is the nitrous arming toggle

Thread from the dead. But I saw this and noticed the tight fit due to the hot-side pipe. Do you have a vertical flowing intercooler?
 
yea,my FMICflows bottomtotop, but the reason my hot pipe is lke that is so I could put the OEM fans back in so i could use my AC on hot nebraska summer days without overheating (i spent almost 700in slimlines and none worked)
 
yea, it's just a matter of sanding/grinding and polishing, but it'smore than I want to do until I have my final setup, I just changed it yesterday by putting a 9" K&N on it
