The Doc's tranny waggin' Options

[partwerks]

A friend of mine has something that I thought he said they only made like 11 of them. I think he called it a DK10??

One side of the engine is done today. The aluminum is ugly, but I had to do a lot of building up to do, and subsequent grinding. Eventually, I had to leave some globs on as the material was too thin. New injectors and hardware are installed (IMG:style_emoticons/default/smile.gif)

Here is a link to the agonizing design of the CIS system (IMG:style_emoticons/default/smile.gif)

[Dr Evil]

So, one of the design things needing to be addressed to meet the and of the month deadline for completion is how to hook the CIS box to the intake. I have been looking at Volvo air boots, but the best think I am seeing is the 924 boot here:

Any other suggestions? I am wishing to go from vertical to horizontal and with the 924 boot I can do this with a simple elbow (IMG:style_emoticons/default/smile.gif)

I hope you bring this to Hershey Mike, cant wait to check it out

That looks very similar to the 3.0L intake!

You can do something like I did for the Volvo intake and the welded up elbow. I cut the original intake boot and made the elbow to fit my needs! Then I clamped the cut intake to the elbow to match everything together!

[Dr Evil]

The problem I see in cutting the OE boot is that it is oval. The 924 boot is circular so plumbing the rest would be easier with standard plumbing supplies (IMG:style_emoticons/default/confused24.gif)

At present, I am waiting to get the pipes for the down tubes, they ship on the 19th and this has held everything up. Once the plenum is built, i can install the engine, decide location of the airbox, measure FI hose lengths and order them, and make new engine tin while I wait. I can still make the end of the month deadline, but having to order out all of these damn parts is killing my timeline.

Back to posting in this thread. I have the heads done up and installed, the adapters welded up and installed withe new injectors and hardware, welded on the mounts for the AAR and the WUR. I diagrammed out the vacuum, fuel and electrical schematics that I will use to guide assembly and found that I am in need of 3 electrical plugs for the AAR, WUR, and CSI. I also found that I need a thermotime switch for the CSI....I think a 914 one should work so any used ones out there? (IMG:style_emoticons/default/biggrin.gif) You can also appreciate the billet pulleys I got to keep the belt form getting scruffed on rusty steel pulleys. Still need to keep the man crank pulley rust free and the alternator one, too.

Some more victory last night with the making of the base plates for the intake system (IMG:style_emoticons/default/smile.gif) I first made my own gaskets, then I transferred the pattern onto the 1/4" 6061 Al plate and drilled out the holes. It all lines up! The down tubes are reported to ship tomorrow and I cant wait for them to get here so I can get this all buttoned up and installed for testing.


I also took a different route with the air box for the flapper and dist. I had been generously given a nice aluminum setup out of a Volvo, but the filter that would have to be used would be of the cone-style KN that would be pretty small. So, I came across a setup for a VW rabbit (I think) that uses readily available disposable filters. I also found a refresh kit with new copper washers and a gasket for the flapper assembly. Good price and looks appropriate for what I need.

Wonder what the wagon would look like with a 914 painted on the side. (IMG:style_emoticons/default/idea.gif)

The down tube stock showed up today and I got to work quickly after I got home....from work (IMG:style_emoticons/default/rolleyes.gif)

Welding aluminum is difficult. I have yet to need to weld a straight line (IMG:style_emoticons/default/dry.gif) I think I finally got it dialed in. I also think that gun was not feeding uniformly so I fixed it (IMG:style_emoticons/default/smile.gif)

[Dr Evil]

These are the last welds when I got the feed and the power correct. You have to weld fast!

[rick 918-S]

Hey Mike, Get a stainless wire brush and clean all the pipe surfaces where your welding. Use a new clean brush that you only use for aluminum.

Edit: On second look I think I can see where you cleaned the 90's

[Dr Evil]

Yup, I have a brush just for this that is stainless. I cant imagine how crappy the welds would be if it didnt (IMG:style_emoticons/default/blink.gif)

The first set was a PITA as it would randomly burn through. I think I was welding too much at a time. The metal would flow through the burn through and make nice, HUGE boogers that I had to dremel out (IMG:style_emoticons/default/dry.gif) If I could weld better, I would be done (IMG:style_emoticons/default/biggrin.gif)

[brer]

good work mike! took me awhile to get the hang of it.
when you can weld a beer can back together you're getting good.

[Dr Evil]

I started on the hard stuff with the smaller tubes. I just finished up the large tubes and my welds were going awesome! Then I ran out of wire (IMG:style_emoticons/default/dry.gif) I put my other role of 4043 in and it kept misfeeding.....it was .030 and the feed wheel was .035. Off to the store to get a new spool and all they had was 54XX or something. Welded very different. Nothing a sanding disk couldnt fix (IMG:style_emoticons/default/thumb3d.gif)

I am taking a break for the moment to post pics (IMG:style_emoticons/default/smile.gif)

[Dr Evil]

Alright, I am calling it a night. I am out of sanding disks anyway. I got one side almost completely done. I had to re-weld the one side as I noticed cracks when I hit it with the hammer (good test). Added material and ground it down again. All that is left on this piece is to throw a bunch of nuts in it and shake it around to break loose any metal boogers that might have formed with welding.

PROOF that I can weld in a straight line (IMG:style_emoticons/default/wink.gif)


Second side


Both done (IMG:style_emoticons/default/smile.gif)

[Dr Evil]

So, rattled some nuts around in them and got only a few little nuggets of slag. Then I leak tested them.......and went to repair some welds (IMG:style_emoticons/default/rolleyes.gif)

Now to leak test the other one (yay).
