H2O Lines - Right down the CENTER.

FRONT & CENTER



re: "Tunnel" shot. Both barrels.

On a previous project (79 vert) I ran mild (1 1/2" or 1 7/8" ish, to long ago) steel tubing for the water lines straight down the tunnel. I utilized the small access panel in the front (for the shifting rod) to get the pipes in. And cut two oval wholes out the back/bottom just below and before the horns split.

It really worked well. Everything was pretty much kept inside. There was no shifter interference and I don't belive my shot threw the rear tunnel had any impact on the pan. I did have a few "hang ups" as I tried to pass the pipes down and back. But nothing that a sledge couldn't handle :wink:

I'm guessing it was more work than attaching directly to the bottom of the pan. But it sure cleaned up things. I kinda' remember the tunnel feeling warm(er) but nothing I would change next time.

Actually, what I might try with my current sedan. Since I'm running a type II trans with the shifter "over the top. Pumping the entire tunnel full of a (light weight) insulation foam? I would be insulating the watter lines and (guessing here) cutting down on a serious noise producer? I'm guessing that hollow tunnel really has to amplify the noise coming up from the transaxle? Talk about your 8Ft trumpets?

Anybody care to ring in on these hair brained ideas?

Re: H2O Lines - Right down the CENTER.

thanks for the info i have been thinking about doing the same to clean the whole mess of water lines from under the car. what kind of pipe did you use, i was thinking about going with copper lines all the way to the back and how big where the hole where the pipes came out. by any chance do you have some pictures that you can share with the rest of us:smash8:

So much extra work running them through the tunnel and you don't get to take advantage of the free cooling cooling having them under the car in road draft.
