..... Briz,,,, i went down to the hardware store and picked up a alluminum drier hose, wall connecter, clamp, a joint of 6'' wood stove pipe, and a 4'' rubber plumbing connector with clamps.... and that is what I used.... I squeezed the stove pipe down to 4'' and cut/fitted the air cleaner to the pipe and then welded it in..... On the inside, I cut the flange pan out from a old qjet air cleaner that I had , cut the locator tabs off of it, then I cut the small carter flange pan out of the pancake unit and welded the bigger one in... spacing it the same distance from the carb flange.... when I got every thing welded up, I filled the highs and lows with body filler and block sanded it and rattle can sprayed it.... I would have never guessed it was snap lock pipe. very well done!
Actually,,,, i have found that stuff to be very good metal....it welds good, cuts good, the only thing that you have to contend with is that it is essentually a spring....but it is great for fabricating stuff....
Designing and building HVAC systems, I use alot of metal pipe and pre fab duct. I just never tried to weld it.Screws, tabs and tape is the preferd method out in the feild
Actually, to get it down to 4'',,, I lapped it over and ran some sheet metal screws into it to hold it while I welded it...had to tack it about every 2 in. and then go back and fill it in... then cut the excess off with my cut off tool.... on the inside , I had to make a large oval cut so the air could get from the pipe , into the air cleaner can..... and of course , I had to fashion a end plug for the passenger side.....
Most W/S base heater air sources have drain holes for water; on some cars they end in a metal tube and a hose leading down to the ground, some have screen covers to stop leaves etc. from blocking the drains. Stopped drains is a major cause of cowl rust and dashboard leaks. A negative: any gasoline vapor coming from the bowl vent, throttle bore, etc. goes into the A/C can, and may reach your heater vents inside the car. Depending on the W/S angle, etc. you may get light pressure there as low as 50 mph - which is why the heater works. If the area were under vacuum, the fan would do much less.
Hmmm.... Looks real good Doc! Wonder what would happen if it was plumbed to the A/C box for REAL cold air?:idea2: (if you had A/C...) Erik
Well, Erik, i can tell you from first hand experience,,, me and my uncle got the bright idea:idea2: that we would build us a ''supercharger'' out of a squirrel cage blower that was in a wrecked car in my grandads wrecking yard.... Now this ''supercharger'' was to go on a flat head ford with a 2 barrel carb that was about as big as 2 eye droppers tied together....:laugh: We worked and worked and welded and welded... and when we got thru with it ,, you could not close the hood...:Brow: Heck, you could not even think about closing the hood...:Brow: so we took it off... it was the most rediculous looking thing you ever saw, stuck up 2 ft. in the air,,,, took two days,,, but we off and running... went thru town so people could see,,,, they saw alright,,, pointing and laughing...ou: and when we got out on the main highway and flipped the switch to the ''supercharger'' the engine sucked enough air thru it, that it did not matter that the electricity was on...in fact, the car was way slower than it was before,,,,the only thing that we could tell that it did was to make it idle rough....got a lot of laughs though....:laugh: :laugh: so if you hooked it up that way , it would overwhelm the blower and you would not get any cold air out of the a/c or heater inside the car .... but that idea is not so far fetched , I have seen Z28 cameros that was drawing off the heater chamber...where it comes into the WW chamber....actually the set up is a old nascar set up... the ww chamber is a high pressure area from the wind shield....and the air moves down the glass, not up as one would think...
LOL! Thanks for the laugh! ....oh wait... I guess I wasn't supposed to laugh at that... Probably still strikes a sore spot with you...ou: Actually, I wasn't thinking along the lines so much as using the blower fan for positive pressure, but rather more gains in cold air density. It has been claimed that for every 10 degrees in temperature reduction results in 1% increase in horespower and torque. If thats the case, how cold of air can we blow into our intakes? ...and here I thought all along "air density" was to be used as a correction factor for modern engines with a Mass Air Meter to maintain proper air fuel ratio.... Erik
Hey, Erik,,,I have been laughed at so many times that i cant count them.... heck, I laugh about it my self... and there is more where that came from...:laugh: :laugh: feel totally free to laugh at me....:Brow: :Brow: That car I was telling you about was a 49 ford coupe,,, wish I had it back.... come to think about it ,,, I wish I had my uncle back,,, but sadly he made the decision to smoke....
