Stock tank

how are you doing the fuel pickup and line routing into the tank?

For the fuel lines the plan is to remove the fuel pump from the stock assembly and just have a tube pickup inside there. Then I'll use a little bit of the stock lines and then have 8mm barb to -6AN adapters. I've been told this type of setup works fine, as long as you don't put the fuel pumps really far from, or way above the tank.

More work done. Started getting a heater core back into the car. I originally had the stock one installed, but removed it at one point and it never got re-installed, partly because it was big and got in the way. It is nice to have one though when its a bit colder or especially if its raining.

The new set up Im installing will use a 9000 oil cooler as the core, and two 3in inline blowers. For the heater valve Im re-purposing a C&R remote oil filter housing with a built in bypass valve. Because I don't want to be filtering my coolant, I welded a small aluminum "bowl" where the filter would have gone.

Way to go Pascal on great climb yesterday at Mt. Washington! It was an awesome day with great weather, great cars, and fast times. My lady was so giddy when she saw the little old SAAB blasting up the mountain :)

I had transmission issues at Burke this weekend. Last night I pulled the side covers and it looks like the Pionion housing is now in two pieces. I drove the car for a pretty short distance after feeling something wrong, and the gear oil looked ok, so hopefully there wasn't to much damage to anything else.

Just checking, but you didn't use std 4spd cast iron pinion housing did you? Those fail on stock 105 HP 99's.
You need the 86-88 5spd aluminum one...

It is definitely aluminum. Did the later 4 speeds have aluminum ones?

some of them were sand cast ? which I thought you also didn't want to use. Or was that cast iron?

See pages 39-40

Most of the 4spd I've seen are cast iron, Its possible that 79-80 4spds used aluminum? At any rate a 4spd aluminum one would have been the die cast or sand cast variety. I have a picture of the good one somewhere.

They still were available from saab a short time ago, but I checked yesterday and they are NLS. Not that there is a shortage of blown up gearboxes to pull from.

That's the chillcast unit, stolen from this thread viewtopic.php?t=867

Erickson used to have custom carrier available that took one larger bearing (like on the '89+) but fit the early gearboxes. I don't think the big bearing is necessary for high power (I think it's more a long term wear benefit) but it would be cool to have a batch of really nice billet aluminum carriers custom machined....

it looks like the kind of part that a machine shop could mill out of a chunk of aluminum for you relatively easily.
