so this forum was down when I started all of the install but wanted to take some time to catch everyone up on this site since a fair amount of folks asked me to post progress... keep in mind the trans is installed inverted with a custom Chevy bellhousing but the S4 comes standard upright with the Porsche bellhousing.

it would be nice if this forum allowed more than one pic per post as it takes a long time to upload progress pix one at a time (IMG:style_emoticons/default/wink.gif)

Started off with installing the Kennedy Stage 2 dual 8" disk clutch - good for 550 ft-lbs of torque (at sea level racing I make 438 ft-lbs so should be plenty).

The flywheel is 10" diameter overall and the custom pilot bearing installed in the Chevy crank

the TO bearing installed in the Mendy with a new clutch fork I had to swap out - they accidentally installed the stock S4 fork and the inverted setup required a 180deg opposite fork - Dwight at Mendeola next day aired this one to me so I could get the ball rolling which was solid cust service.

the shim piece that had to be custom fabbed for the early Chevy. The bellhousing is for an LS series engine and the early setup requires this shim to get input shaft spacing correct and clutch stuff aligned properly.

so you LS guys wouldn't need this shim at all.

installed. stabbing the beotch took about an hour of fighting (anyone who has stabbed a trans knows what a PITA that can be - sometimes is just goes and sometimes it doesn't).

I was sitting on the ground behind the car getting ready to call a friend to swing over for help and out of nowhere *kathunk* and it just fell together!! I jumped up pushing on the back so it wouldn't fall back and got a couple bolts in it ASAP (IMG:style_emoticons/default/smile.gif)

the starter is back on the left side down at 7 o'clock. With an inverted 930 it is on the opposite side at 5, stock is upper left at 10.

so with the extra shim in place I have a bit more axle angle - you can see the notches I had in the original frame for extra boot clearance but no problem now since switching over to high angle off-road tapered 930 boots after I had a couple stock 930 boots tear.

I used the original breather tube location to put clear hose to easily check fluid fill level in the trans. Then I fabbed up a bracket to mount the trans at the rear support.

I used high grade hardware torque rather high at 50 ft-lbs to get a lot of joint stiffness with the spacers so I wouldn't get bolt bending. I needed spacers so there would be slop somewhere in the system when time comes to remove stuff again.

lightweighted the simple shifter that Dwight included in my purchase - it seems to work rather slick, just used some rather thick steel to make the housing so I felt compelled to try lightening something for once (IMG:style_emoticons/default/laugh.gif)

The trans BTW was 175 lbs!!! v. 130-ish for the 930 and probably double the 901.

my friend Ken swung by tonight with his TIG welder and welded the bracket in place, welded the shifter to the plate I made to mount it, and welded up some new brackets I made for the oil coolers. I will snap shots tomorrow as I put all of that back together. Just waiting on shift cables at this point - I ordered last Monday but due to holiday shutdowns and such I don't think they will even ship until this Monday.

I might get it back together enough to run tomorrow and blast around the block in 1st gear tho' if it doesn't snow too bad tonight (it is wanting to snow all evening and we have a slight blanket right now). Snow, ice and slicks don't mix too well, especially coupled to a 50mph 1st gear and 400 ft-lbs of torque hahahaha.

(IMG:style_emoticons/default/aktion035.gif) Glad you got everything together, that tranny is wicked!
Nice job, I can't wait to check it out.
Dana.

Looks like that should hold your SBC torque together nicely!

At the very back of the transmission where your chassis is cut, was that done to accomodate the Mendola only? Or did you need that space for the 930 also? Either way, great looking tranny!

Dana - thanks man, obviously my buddy was able to weld in the couple items I needed, I know you are moving so didn't need to bother you.

atomix8 - yes the bar needed to be cut to accommodate the Mendeola BUT that said, the Mendeola's overall length and the 930's overall length are nearly identical. The difference is the 930 housing isn't near as bulky and doesn't extend as far back as the Mendy, but the shift rod out of the transaxle, engaged in gear at full length, is only about 1/2" shorter than this.

If you had an LS engine they would be essentially identical since the spacer I ran is 0.400" thick.


Now the fun part, I blasted it around the block in first gear today... DAMN I forget how much fun this thing is to drive. Fricken go-cart with plenty of right pedal (IMG:style_emoticons/default/smile.gif) The clutch actuates almost instantly so I can adjust the pedal to maybe an inch or so of throw! That is NICE and the pedal pressure is very light. The new disks are nowhere near broken in but I can say they don't grab excessively and I was in fact able to slip it a bit to get out of the garage and the big dip at the end of the driveway. Neighbors probably think I am nuts to see a car running around with no rear end bodywork and just a bunch of engine and trans hanging out there (IMG:style_emoticons/default/laugh.gif)

the new oil cooler mounts and the rear mount welded into place. It was a real treat for Ken to lean over and TIG nearly upside down on the rear mount.

finished up the install for the most part tonight - just need to get a couple shift knobs and weld mount stud to the shifter that match them.

made some brackets yesterday for the cables and buttoned everything up tonight.

forward control bracket and cable installed, reverse looks the same, just opposite side of trans
